Foundation Repair Questions and Answers

They are a reliable and safe way to re-level and support sagging floor joists in a house. We reach the underside of the floor through the crawl space and use the jacks to bring the floor back and hold it there.

For a solid foundation the jacks are set on concrete piers. Four by four lumber is placed inside the jack, the lumber is secured to a horizontal beam with a splicer, and then the assembly is jacked into position.

Jacks are available with or without thrust bearings in the adjustment nut. The bearings reduce friction when the adjustment is being made under load, which makes it easier to jack the weight. On a heavier load that difference matters.

It should not be. Bringing a floor up too fast puts stress into finishes above and can crack drywall and plaster. Adjustable jacks allow the correction to be made gradually, which is a good part of why they are used for this work.

It is a type of Atlas Resistance pier built for foundation lifts of up to four inches. The bracket is installed directly beneath the footing, and it transfers the weight of the structure down to deeper, more stable soil, bypassing the surface soils that caused the settling in the first place.

Pier diameters come in two and seven eighths, three and a half, four, and four and a half inches, with capacities from thirty up to seventy and a half kips. Reinforced sleeve options are available where the load demands more. There are also Standard-Series and N-Series bracket models to suit different structural conditions.

Select models meet structural requirements under the BOCA National Code, the ICBO Uniform Code, the SBCCI Standard Code, and the 2000 International Building and Residential Code, under ICC Legacy Report NER-579.

No. They are used on residential, commercial, and industrial foundations. The range of pier sizes and capacities is what makes that possible, because the system can be matched to loads well beyond what a house puts down.

The under footing bracket system is engineered for lifts up to four inches, and it is well suited to correcting moderate settlement. How much of that is achievable on your building depends on how far it settled and what the structure will take. We will tell you what is realistic before we start.

We excavate down to the footer in the affected area and clean the foundation wall and footer so the surface is ready. Then we apply an asphalt material called Blackjack, rolled or brushed on generously to seal the pores in the block. Over that goes a second asphalt based material called Bituthene, which comes in rolls and adheres to the Blackjack. Then we install a protective flex board called Hydroduct over the Bituthene to shield it from gravel and dirt, and back fill with gravel and dirt, finishing with a positive slope away from the house.

Each layer does a different job. The Blackjack seals the pores in the block itself. The Bituthene is a membrane that bonds over the top of it and forms the actual barrier. The Hydroduct protects that membrane from being torn or worn through by the gravel and dirt when we back fill. A single coating on its own would not survive the back fill.

It is not better in every case, it is different. Exterior work stops water before it reaches the wall, which is the more thorough approach when the conditions allow it. It also requires excavation, so access matters and it costs more to do. Interior work is less disruptive and manages water once it arrives. We recommend based on how the water is getting in, not on which job is larger.

Because it decides where the next rain goes. All the sealing in the world does less good if the ground still tilts toward your house and holds water against the wall. Creating a positive slope away from the house is what promotes proper drainage and keeps the pressure off the foundation you just sealed.

Pressure from the soil outside. When the ground around your foundation takes on water, it expands and pushes against the wall. Block walls are strong straight up and down but far weaker against a sideways push, so the wall bows in at the middle or cracks along a mortar joint. That is hydrostatic pressure, and it does not let up on its own.

Carbon fiber bands are for walls with vertical or horizontal cracks from hydrostatic pressure where the wall has not moved far. They bond to the wall and hold it from moving further, and they stay flat so you do not lose floor space. When a wall has bowed enough that holding it is not sufficient, we move to steel.

The beam is anchored to the slab below and bolted to the floor system above with half inch bolts. That ties the wall into the structure at both ends and gives it the strength to resist the pressure pushing on it. It is the right answer when a wall needs real reinforcement rather than crack repair.

Anchors work against bowing. Rather than bracing the wall from the inside only, an anchor reaches out into stable soil beyond the pressure zone and holds the wall from that side. They are used to keep a bowing wall from moving further, and in some cases to bring it back over time.

It depends on how far it has moved and what is behind it. Some walls can be brought back toward straight. Others are best held where they are, because forcing them further risks doing more harm than good. We will look at your wall and tell you honestly which of those you are dealing with.

Interior waterproofing manages water that has already reached the basement. We install a drainage channel around the inside edge of the floor, collect the water that comes through cracks in the wall and floor, and pump it away from the house. Exterior waterproofing stops the water further out. We excavate down to the footing, seal the outside of the foundation wall, and give the ground a slope that carries water away. Interior work is less disruptive. Exterior work addresses the problem before the water ever touches the wall. Which one is right depends on how the water is getting in.

Because the water table moves. During heavy rain or a fast snowmelt, the water level in the soil rises and presses against the basement wall. That pressure pushes water through cracks that stay dry the rest of the year. It is also why a basement can be dry all summer and then leak in one bad week of spring.

They cause more of them than most people expect. A clogged gutter or a downspout that empties right at the corner of the house puts a large volume of roof water directly against your foundation. Moving that water out away from the house is often the cheapest fix available, and sometimes it is the whole fix.

That is efflorescence. It is mineral salt left behind after water moves through the block and evaporates. The residue itself is harmless, but it is proof that water is passing through the wall, and that is worth paying attention to.

Usually, because the smell comes from moisture. Once the water is controlled and the humidity comes down, the conditions that cause the odor go away with it. In basements that have stayed wet a long time, a dehumidifier helps hold the humidity down afterward.

Sometimes the cracks are the whole story and sometimes they are a symptom of movement in the wall. If a wall is bowing or cracking from pressure, that needs to be addressed structurally, not just sealed. We will tell you which situation you are in when we look at it.

Carbon fiber bands work on foundation walls with vertical or horizontal cracks caused by hydrostatic pressure, where the wall has cracked but has not moved far out of line. If the block has sheared or the wall has displaced more than about an inch, carbon fiber is not enough on its own and the wall needs steel.

Poor drainage, nearly always. Overflowing gutters, a clogged downspout, or ground that slopes back toward the house. The water has nowhere to go, so it settles in a low area beside the foundation. The soil there expands, pushes on the wall, and the wall bows inward and opens a long straight crack along a mortar joint.

Very little. The bands bond flat against the wall, so you do not lose usable floor area the way you do with a steel beam standing out from the surface. That matters in a finished or partly finished basement.

It keeps bowing. The pressure that moved it does not stop, and the further the wall goes the more involved the repair becomes. A crack that carbon fiber could have handled turns into a wall that needs beams or anchors.

You usually see it upstairs before you see it below. Floors begin to sag, or drywall cracks above the line where the support runs. What has happened underneath is that the structural support or load bearing area has sunk into the ground and the column has failed. Sometimes we also find there were simply too few supports there to begin with.

Block columns are typically placed on concrete footers of thirty by thirty by ten inches, or twenty four by twenty four by ten inches, spaced on six foot centers. The footer is what keeps the column from sinking again, so it matters as much as the column itself.

For maximum main girder support, a double stacked eight inch block column with a solid four inch cap block, built on a thirty by thirty by eight inch footer on six foot centers.

In many cases the floor can be brought back up as part of the work, depending on how far it has dropped and what the framing will take. Where a full correction is not advisable, the goal becomes stopping the movement and supporting the structure properly from there on.

It is a four inch corrugated perforated pipe with a sock cover, installed along the interior footer to carry water to a sump pump or to a low spot where it can leave by gravity. The drain is back filled with gravel, and in some cases masonry.

A crawl space drain is a good alternative to exterior excavation and waterproofing in hard to reach areas. Some houses simply do not have the access around the outside to excavate, and on those a properly installed interior drain does the job without tearing up what is above ground.

Not completely. The drain removes standing water, which is the first job. To get the full benefit you also need a vapor barrier or an encapsulation system, because that is what brings the moisture levels down and improves the air quality under the house.

It keeps soil and sediment out of the perforations so the pipe keeps draining years after it goes in. A perforated pipe without a sock silts up over time, and a clogged drain does nothing for you.

The duration of the encapsulation process depends on the size and condition of your crawl space. Typically, it can take a few days to a week. We can provide a more accurate timeline after a brief crawl space inspection. Give us a call today to schedule an inspection.

The cost of encapsulation varies based on the size of the crawl space, the materials used, and the complexity of the job.  Contact us for a free estimate tailored to your specific needs.

Encapsulation significantly reduces the risk of mold and mildew growth by controlling moisture levels in the crawl space. However, existing mold should be professionally removed before encapsulation.

Yes, once your crawl space is encapsulated, it becomes a clean, dry, and safe area suitable for storage.

While some homeowners may attempt to encapsulate their crawl space, it is generally recommended to hire our professional team to ensure the job is done correctly and effectively, especially considering Knoxville's specific environmental factors.

Regularly check the encapsulation barrier for any damage, monitor the humidity levels, and ensure the dehumidifier or ventilation system is functioning properly. Professional inspections are also advisable.

It means sealing the crawl space off from the outside air and the ground moisture, and insulating it, so the space underneath your house stays dry and stable instead of following the weather. Sealing and insulating are both part of it. One without the other does not do the job.

Because venting was based on an idea that has not held up in a humid climate. The theory was that outside air would dry the space out. In East Tennessee summers, the outside air is warmer and wetter than the crawl space, so what actually happens is that the moisture condenses down there. Sealing it stops that cycle.

It generally helps. Your floor sits directly above that space, so when it is damp and unconditioned, your heating and cooling work against it all year. Sealing and insulating the crawl space takes that load off. How much you save depends on your house, so we will not quote you a number we cannot stand behind.

It removes much of what draws pests in. Insects and rodents are looking for moisture, darkness, and a way in. Sealing the space takes away the damp conditions and closes off the openings. It is not a substitute for pest treatment if you already have an active infestation, but it makes the space far less inviting.

The materials are made to stay in place for the long term. What matters most is that the water problem is solved before the space is sealed. Sealing over standing water or an active leak traps the problem instead of fixing it, which is why we handle drainage first when a crawl space needs it.

You often smell it before you see it. A musty odor in the house, especially on the first floor, usually starts underneath. Other signs are floors that feel soft or bouncy, humidity that stays high no matter what the thermostat does, higher power bills, and more insects than you used to see. If you can get down there safely, look for standing water, wet insulation hanging loose, or wood that has darkened.

Our climate does it. Hot, humid summers push moist air into a cool crawl space through the vents, and that moisture condenses on everything down there. Older homes around here were built with vented crawl spaces because that was the standard at the time, and those vents let the wet air right in. Add a wet spring and it stays damp under the house for months.

It does. A good deal of the air you breathe upstairs started in the crawl space and worked its way up through the floor. If it is damp and musty down there, that is what is moving through the house. This is why people often notice the smell and the allergy symptoms before they notice anything structural.

That depends on what we find. It may mean drainage to get standing water out, sealing and insulating the space, replacing supports that have rotted or settled, or some combination. We inspect first, tell you plainly what is causing the problem, and then price only the work that addresses it.

No. The inspection and the estimate are both free, and there is no obligation attached to either one.

In most cases yes, and it is usually a better storage space afterward than it was before, because it is dry. We will let you know if anything about your particular setup makes that a bad idea.

The floor system of your house. Girders and joists run across the crawl space, and the posts and columns beneath them carry that weight down to footers in the ground. When a support settles or fails, the floor above it drops with it. That is why sagging floors and cracked drywall upstairs so often trace back to something under the house.

We install four by four or six by six treated posts together with adjustable support jacks resting on solid concrete footers. The footers are eight inches, or twenty four by twenty four by eight inches depending on the load. It is an effective way to level and stabilize sagging floors without a large expense.

Because the footer is what keeps the support from sinking. A post set straight onto crawl space dirt will settle again, and you will be back where you started. Sizing the concrete footer to spread the load across enough ground is what makes the repair last.

Usually moisture, settling, or not enough support to begin with. Damp conditions rot wood posts and rust hardware. Soil under a footer settles and lowers the post along with it. And sometimes we find the house was simply built with fewer supports than the span really needed.

Often a good deal of it can be recovered. The correction should be made gradually rather than all at once, because lifting a floor too quickly puts stress into the finishes above and can crack drywall and plaster. Adjustable jacks are well suited to that kind of measured adjustment.

Structural engineers recommend at least ten feet away from the foundation. Anything shorter tends to put the water back into the soil close enough to the wall that it still causes trouble.

They let water collect near the foundation instead of moving it away. That standing water is what draws unwanted insects and critters, and it puts moisture right where you least want it. They look like a solution but they leave the water where the problem starts.

We connect a four inch corrugated pipe to the gutter with a four to six inch attachment, bury it, and run it out to daylight. PVC pipe is available as well. Leaving the exit point partly exposed matters so the line can be checked and cleared.

They do. Clean gutters and free flowing downspouts are one of the least expensive things you can maintain, and they carry a large share of the water that would otherwise end up against your foundation. Many of the wet basements we look at start at a clogged gutter.

Most people notice the small things first. Doors and windows that stick or will not latch the way they used to. Cracks above door frames. Floors that feel uneven when you walk across them. Gaps opening where the trim meets the wall. Cracks in brick or block outside, especially stair-step cracks that follow the mortar joints. Any one of those on its own may be nothing. Two or three of them together usually means the house has moved, and it is worth having someone look.

Soil and water, almost every time. East Tennessee has a lot of clay, and clay swells when it takes on water and shrinks back when it dries out. That movement happens under your footing season after season. Add in our heavy summer storms, gutters that overflow, or ground that slopes toward the house instead of away from it, and the soil under one part of the foundation gives way faster than the rest. That is what makes a house settle unevenly.

Usually, yes. Settling is driven by conditions in the soil, and those conditions do not correct themselves. A hairline crack that lets water in will let more water in next year, and water is what causes most of the damage underneath. Waiting also tends to raise the cost, because a house that has moved further needs more piers and more lift to bring it back.

We dig, but we dig by hand and only where the work requires it. Hand digging takes longer than bringing in equipment, and we do it that way on purpose. It lets us see the footing and the soil conditions with our own eyes before we set anything, and it keeps the disturbance to your yard down to the area we are actually working in.

It depends on how many piers the house needs and how deep we have to go to reach stable soil. A small job on one corner may be finished in a day or two. A larger job along a full wall runs longer. We will give you the honest timeline when we give you the estimate, not after the work has started.

Yes. We come out, look at the problem, explain what we find, and give you a written estimate at no cost and with no obligation. If we do not think you need the work, we will tell you that too.

Often it can be lifted. With a pier system we can usually recover some or all of the settlement, depending on how far the house has dropped and what the structure will tolerate. Sometimes the right answer is to stabilize where it sits rather than force a lift that would crack finishes upstairs. We will walk you through which one applies to your house and why.

Because of the ground here. Knox County has clay-heavy soil that does not drain quickly, and heavy summer storms deliver a lot of water in a short time. Water that cannot soak away has to go somewhere, and on many lots that somewhere is up against the foundation. A french drain gives it a better path.

Much of the Knoxville area sits on ridges and slopes, and on that kind of lot the useful place for a drain is uphill of the house, intercepting water before it arrives. That is called an interceptor or curtain drain. On flatter ground a perimeter drain around the foundation is generally the better fit.

It depends on the job. The NDS EZ Flow system uses four inch corrugated perforated pipe wrapped in foam peanuts rather than gravel. It saves labor, is crush proof, moves about thirty percent more water than traditional pipe and gravel, and carries a hundred year life span rating. A traditional system uses the same pipe wrapped in a soil separating sock and topped with gravel or soil, and it suits landscaping drains, perimeter drains and roof run-off well.

It can, by lowering how much water is sitting in the soil around the foundation in the first place. Whether that is the right first step depends on how the water is reaching your crawl space. Sometimes the answer is an exterior drain, sometimes an interior crawl space drain, and sometimes it is as simple as moving the downspouts.

A french drain is a trench, so the line of the trench gets disturbed and then restored. We keep the work to the run the drain actually needs. As with our foundation work, we would rather take the time to do it by hand and neatly than bring in equipment and tear up more ground than the job calls for.

A perforated pipe buried in the ground that collects water out of the soil and carries it somewhere it will do no harm. We install two types. A traditional system uses four inch corrugated perforated pipe wrapped in a soil separating sock and topped with gravel or soil. The NDS EZ Flow system uses the same four inch corrugated perforated pipe wrapped in foam peanuts instead of gravel.

The EZ Flow system takes less labor to install because there is no gravel to haul and place, and it moves about thirty percent more water than a traditional pipe and gravel system. It is crush proof, and it is rated for a hundred year life span. On the right job it is both quicker to put in and higher capacity.

Traditional systems work well for landscaping drains, for a foundation or perimeter drain, for an interceptor or curtain drain that catches water moving across a slope, and for roof run-off. We offer both so the system fits the job and the budget rather than the other way around.

A properly installed system lasts many years, and the EZ Flow material carries a hundred year life span rating. What shortens a drain is silt getting into the pipe, which is exactly what the soil separating sock is there to prevent.

Somewhere it can leave the property safely, away from your foundation and away from your neighbor. Working that out is part of designing the system, and it depends on how your lot falls.

A grate drain is a surface drain with a visible grate over a catch basin. They are commonly installed in driveways to capture rainfall and redirect it away from the house. The typical situation is a home or garage that sits lower than the road above, so water runs downhill and floods the garage or the front of the house.

Most grate drains are four inch drains with a durable plastic grate on top. Installed through a concrete slab, the grate runs from four to twelve inches, in hard plastic or steel, resting over a catch basin that collects both water and debris.

The catch basin is designed for that. Debris collects in the basin rather than washing into the line, and the grate lifts so it can be cleaned out easily. Checking it after heavy leaf fall is usually all the maintenance it needs.

Depending on the flow, the drain may need to be slanted, recessed in concrete, or widened. We size it to what your property actually sheds rather than dropping in a standard part and hoping.

When a below grade wall has more than about an inch of displacement or shearing. At that point most engineers recommend i-beams. If the blocks are sheared or displaced, carbon fiber is not an adequate repair and beams need to go in.

A W6 by 16 i-beam, unless an engineer specifies something different for the situation. It is anchored to the slab below and bolted to the floor system above with half inch bolts.

The gaps between the wall and the beam get filled with a high strength mortar. That closes the space so the wall bears evenly against the beam instead of flexing into the gap, which further reduces movement.

In some cases the floor system above needs blocking added to keep the wood framing from twisting or moving once the beam is loading against it. It is not needed on every job, but where the framing calls for it, it is part of doing the repair properly.

We remove a section of concrete along the affected area and clean the trench of debris. Then we lay a four inch corrugated perforated pipe wrapped in a soil separating sock, and pack gravel around it so the pipe does not shift. We install bead board against the wall so moisture coming through the block can reach the pipe underneath the floor, then we pour the concrete back over the top.

It keeps soil and fine sediment out of the perforations. Without it, the holes that let water into the pipe gradually silt up, and a clogged drain does not drain. The sock is what keeps the system working years down the road.

The drainage channel carries it to a sump pump, and the pump moves it away from your property. The system collects the water that comes in through cracks and crevices in the walls and floor and gets it out before it can stand in the basement.

We use one to control the humidity after the drainage is in. Getting the standing water out is the first job. Bringing the humidity down is what prevents rot, mold and mildew buildup, and dust mites, and that takes a dehumidifier in most basements.

Generally yes, because the work stays inside and we are not excavating around the house. The trade-off is that interior work manages water after it reaches the wall rather than stopping it outside. Both approaches are valid. Which one fits depends on how water is entering and what access we have around the foundation.

It is common enough that most foundation contractors in this area stay busy. Knox County has clay-heavy soil that swells and shrinks with moisture, limestone bedrock that can form voids underneath, and heavy summer rain. That combination puts more movement into the ground here than in places with sandier soil and steadier rainfall.

Karst is the term for landscape formed where water has dissolved limestone bedrock over long periods, leaving cavities, voids and sinkholes. Knox County sits in karst terrain. It does not mean every property has a problem, but it does mean soil can migrate down into a void and leave less support beneath a footing than there used to be, sometimes with no sign at the surface until the house moves.

We cover the greater Knoxville area, including West Knoxville, Bearden, Farragut, Hardin Valley, Karns, Powell, Halls, Seymour and Louisville, along with Oak Ridge, Lenoir City, Maryville, Alcoa, Clinton and Sevierville. Our shop is at 1058 Lovell Road in Knoxville.

People notice them most often in two stretches. Late winter into spring, when the ground is saturated and pressure against basement walls is at its highest. And late summer, when clay soil has dried and shrunk and a house settles into the gap that leaves. A crack you first saw in March is worth checking again in September.

We schedule the free inspection at a time that works for you, and being based on Lovell Road puts most of Knox County within a short drive. We are open Monday through Friday, 8:30 in the morning to 5:30 in the evening, and we are available for emergency service after hours.

No. The inspection and the written estimate are both free, and there is no obligation to go forward. If we do not believe you need the work, we will say so.

A push pier carries the weight of your house down past the soil that is causing the trouble and onto ground that will hold. We expose the footing, set a concrete cylinder six inches across and twelve inches long into the hole with a powered ram on top and a titanium plate bracing the footing, and drive it down. Then we feed number four rebar through the cylinder and drive the next one in behind it. We keep going until there is enough resistance to stabilize the wall and, where it is possible, lift it.

As deep as they need to. There is no fixed number, because it depends on where the stable soil is on your lot. We drive cylinder after cylinder until the pier builds enough pressure to carry the load. That is the point of a resistance system. The ground tells you when you are deep enough rather than a specification deciding it in advance.

Yes, in many cases. Once the pier is set, we fix an eight by eight by sixteen inch cap block rated at nine thousand psi to the pier, and use a twenty ton bottle jack to make the adjustment. Then we shim from the cap block to the footing to hold the correction. How much lift is possible depends on how far the house settled and what the structure above will take without damage.

We back fill the hole and tamp the dirt as we go so it packs down properly rather than settling later and leaving you a depression in the yard. Because we dig by hand, the disturbed area is limited to where we actually worked.

Both carry the load to deeper soil. A push pier is driven down using the weight of the structure itself for resistance, which suits a house heavy enough to push against. A helical pier is turned into the ground like a screw and does not need that weight, so it fits lighter structures and additions. Which one is right comes down to your house and what is under it.

Re-grading is reshaping the ground around your house so that water runs away from the foundation instead of toward it. Often that means cutting a swale, which is a shallow, gently sloped channel in the ground that collects surface water and carries it in a controlled direction.

Ground settles. Soil that was placed against the foundation when the house was built compacts over the years and drops. Mulch and topsoil get added to beds season after season and build the ground up next to the wall. Neither happens fast enough to notice, and one day the ground tilts back toward the house.

A swale is a shallow depression shaped into the yard that gathers surface water and moves it along a path you choose. It works with the lay of the land rather than against it, and it does the job without pipe or hardware, which makes it a good fit where the problem is broad sheet runoff rather than a single concentrated source.

The ground should fall away from the foundation steadily for the first several feet out from the wall. What matters more than a number is that water never has a reason to stand next to your house. We look at how your lot actually drains and shape it to suit.

Sometimes. On a property where the only problem is surface water sitting against the wall, correcting the grade can be the whole fix. Where groundwater is also involved, re-grading works alongside drainage rather than replacing it. We will tell you which one your property needs.

We use the Manta Ray anchor system. A galvanized anchor head is attached to steel rods that are driven into the substrate behind the wall until they meet refusal. The rod then passes through a steel plate or C-channel on the inside, and a pneumatic piston pulls the rod and sets the anchor. The anchor is holding against undisturbed soil out beyond the pressure that is pushing your wall in.

Most engineers recommend installing them on four to six foot centers along a concrete block wall, with steel C-channel to help spread the support across the wall rather than concentrating it at each anchor point.

Yes. The wall must be filled with concrete before an anchor can be set. A hollow block wall does not have the strength to take the load at the anchor plate, so filling the cores comes first.

Their main job is to keep a bowing or tipping wall from moving further. In some situations a wall can be brought back toward straight over time. How much is realistic depends on the wall and the soil behind it, and we will tell you what to expect before we start.

Water management means controlling where rain and groundwater go once they reach your property, so that water moves away from the house instead of collecting against it. Nearly every foundation problem we see has water somewhere in the story. Getting the water under control is often the difference between fixing a foundation once and fixing it again in a few years.

A french drain is buried. It is a perforated pipe laid in the ground that collects water out of the soil and carries it away, which makes it the right choice for water that is saturating the ground around your foundation. A grate drain sits at the surface with an opening you can see, and it catches water that is already running across the ground, like runoff from a driveway or a low spot in the yard. Many properties need both.

It makes a bigger difference than most people expect. A roof sheds a great deal of water in a storm, and a downspout that ends at the corner of the house drops all of it right against your foundation. Carrying that water out away from the house is one of the least expensive things you can do, and on some homes it solves the problem by itself.

Re-grading reshapes the ground next to your house so it slopes away rather than toward the foundation. Over the years soil settles and mulch beds get built up, and the ground ends up tilted back toward the wall without anyone noticing. Correcting that slope sends rain away from the house from the moment it lands.

We come out and look. The right answer depends on where the water is coming from, how your lot drains, and what the soil is doing. The consultation and the on-site inspection are both free, and we will set them at a time that works for you.

Sometimes, in a crawl space that is already dry and well drained, where ground moisture is the only source. In most East Tennessee crawl spaces it is not enough by itself, because humid summer air coming through the vents is a bigger source than the ground is.

Yes. Sealing the space is the point. Leaving vents open while sealing everything else means you are still inviting in the humid air that caused the problem.

Many people notice that it does, because the space directly beneath the floor is no longer damp and unconditioned. How much difference you feel depends on your house and how the floor is insulated.

In most cases yes, and it is usually a better storage space afterward because it is dry. We will let you know if anything about your particular setup makes that a bad idea.

The foundation is the whole system that carries your house. The footing, or footer, is the widened concrete base underneath a foundation wall or column that spreads that load out across the soil. When someone says a pier was set beneath the footing, they mean beneath that base.

A kip is one thousand pounds of force. It is used to state how much load a pier can carry, so a pier rated at thirty kips carries thirty thousand pounds. Pier capacities in the range of thirty to seventy and a half kips cover residential work comfortably.

It is worth having looked at. A stair-step crack climbs diagonally through the mortar joints of brick or block, and it usually means one part of the foundation has settled further than the part next to it. Whether it is serious depends on how wide it is, whether it is still moving, and what is causing it.

They do, and the cause is often different from an older home. In an older house the trouble is usually decades of soil movement and drainage that has gone wrong slowly. In a newer house on a graded lot it is more often differential settlement, where fill soil under one part of the footing compacts more than the undisturbed ground under another part.

Settlement can show up within a few years of construction on a graded lot, and it can also appear twenty years in. Age alone does not tell you much. What the cracks look like, whether they are still moving, and where the water goes tell you a great deal more.

We are on Lovell Road in Knoxville, which is close to Farragut. It is a short drive, and we schedule the free inspection at a time that suits you.

Because the valley sits between ridges and water runs downhill into it. On a sloping lot, runoff from higher ground arrives at your foundation regardless of how well your own gutters work. That is the situation an interceptor or curtain drain is built for, and it is a common recommendation here.

Not worried, but worth watching. Homes on graded pads can settle differentially in their first years while fill soil compacts. Check the doors, watch for cracks above door frames, and make sure the ground still slopes away from the house after the landscaping matures.

Closing the vents on its own is not the answer, because you also need the space sealed and insulated properly and any water problem handled first. But the instinct is right. Vented crawl spaces do not perform the way they were intended to in a humid climate.

A musty smell on the first floor is the most common tell, because much of the air you breathe upstairs started underneath the house. Floors that feel soft or bouncy, humidity that stays high, and rising power bills point the same direction.

No, but it does mean drainage deserves more attention than it might elsewhere. A higher water table puts steadier pressure on below grade walls, and that pressure is what pushes water through. Controlling where water goes around the house is the first line of defense.

Because only part of a walkout basement is below grade. The wall holding back saturated soil is under hydrostatic pressure while the daylight side is not. Water finds the path of least resistance, and that is usually the buried wall.

Because they are two structures on two footings, and they rarely settle at the same rate. The original house has had decades to find its level while the addition is still finding its own. A separation crack at the joint is one of the most common things we are called out to look at.

Yes. Maryville and Alcoa are both within our regular service area, and we are based on Lovell Road in Knoxville. The inspection and estimate are free.

Not harder, but they need looking at rather than assuming. A house that has stood for eighty years has usually been altered along the way, and what is under it may not match what was drawn originally. We inspect first and tell you plainly what we find before quoting anything.

Often it is the supports rather than the perimeter foundation. Girders and joists run across the crawl space, and the posts and columns beneath them carry that weight to footers in the ground. When a support settles or a wood post takes moisture damage, the floor above drops with it.

Yes, and on some homes that sequence makes sense. Interior drainage gets the basement usable while you plan for the larger job, and the two systems do not conflict with each other.

It depends on whether the crack is the problem or a symptom. A crack that simply lets water through can be handled as part of waterproofing. A wall that is cracking because it is bowing under soil pressure needs structural repair, and sealing it without addressing the pressure just hides the movement.

No. A sump pump runs when there is water to move, which in most basements means during and after heavy rain or a fast snowmelt. A pump that runs constantly in dry weather is telling you something about groundwater around the house that is worth investigating.

Efflorescence. It is mineral salt left behind after water passes through the block and evaporates. The residue is harmless in itself, but it is evidence that water is moving through the wall.

Neither is stronger as a category. Capacity depends on the pier size and the soil it lands in, not on which installation method was used. A properly sized helical pier and a properly sized push pier can both carry more than a house puts down. The right question is not which is stronger but which suits the structure and the ground.

That varies by job rather than by type. Depth to stable soil, how many piers the structure needs, and how much access we have all move the number more than the choice of pier does. This is why an estimate has to come from looking at the actual house.

Both can recover settlement in many cases. How much lift is achievable depends on how far the house dropped and what the structure above will tolerate without cracking finishes. Sometimes the correct answer is to stabilize where the house sits rather than force a lift.

No. Once a pier is set on stable soil and the load is transferred, it is doing its job passively. What is worth maintaining is the drainage around your foundation, because water is what caused the movement in the first place.

It scales with the method and the length of wall involved. Carbon fiber on a short run is the least expensive route; anchors on a long wall is the most. The free inspection produces the number for your wall.

Tie-back anchors can pull a wall back over time, sometimes substantially. Carbon fiber and I-beams stop movement where it is but do not straighten. We will tell you which outcome is realistic before you commit.

A horizontal crack with visible deflection is not something to sit on for a season. It does not stabilize on its own, and the repair gets more expensive as deflection increases. Call and we will come look.

The straps are low profile and can be painted over. They do not take up floor space the way beams do.

Yes — lifetime and transferable to the next owner.

It scales with square footage and with how much drainage or structural work is needed alongside the liner. A dry space that only needs sealing is very different from one that needs a sump and new supports. The inspection is free and produces a written number.

A loose vapor barrier laid on the dirt slows ground moisture and nothing else. Encapsulation seals the space — floor, walls, seams, penetrations — and controls the air inside it. The second one is what actually changes conditions in the house.

A sealed, dry crawl space usually makes the floors above it noticeably less cold and takes load off the HVAC system. That is a real effect, though the size of it depends on your house.

Often yes. Sealing stops new moisture coming in; a dehumidifier handles what is already there and whatever gets in through normal use. We will say plainly whether yours needs one.

Yes. Block columns and adjustable jacks are installed as part of the same visit where the framing needs support.

It is priced by the linear foot and by what the run has to get through — lawn, hardscape, tree roots, or a slope with no natural outfall. The inspection is free and the estimate is written.

Regrading handles surface water and is usually less expensive. A French drain handles subsurface water that grading cannot reach. Plenty of properties need both, and we will tell you if yours only needs the cheaper one.

To a suitable outfall — daylight on a slope, or a collection point away from the structure. Identifying a workable discharge point is part of the inspection, and it determines whether the whole plan works.

Sometimes entirely. If water is being delivered to the foundation by grading and downspouts, correcting that can solve a basement problem without touching the basement. We check the outside first for exactly that reason.

Most residential drainage runs one to three days depending on length and access.

Interior systems manage water that reaches the foundation. Exterior systems stop it reaching the wall at all. Exterior is more thorough and more expensive because it requires excavation. Which one you need depends on where water is entering, which is what the inspection determines.

A regrading and downspout correction is a modest job. A full interior system with a pump is a significantly larger one. You get a written number for your basement after the free inspection.

Only if water is reaching the floor or the footing. If it is coming through the wall above the footing, a pump never sees it. This is the most common mismatch we are called out to correct.

We address moisture remediation as part of the work. Persistent mold is a moisture problem, and it returns unless the water is dealt with.

Yes, lifetime and transferable.

It depends entirely on what is wrong and how much of the structure is affected. A few carbon fiber straps on one wall is a different job from piering a whole side of a house. That is why the inspection and the written estimate are free — you get a real number for your house, not a range off a website.

Yes. Someone comes to the property, looks at the foundation, the crawl space or basement, and the drainage, and writes up what they found and what it would cost. There is no charge and no obligation.

Most residential jobs run one to three days on site. Larger piering projects can run longer. The written estimate includes the expected schedule.

Yes. Financing is available and we can walk you through the options during the estimate.

Yes. The warranty transfers to the next owner, which matters if you sell — a documented, warrantied repair is far easier to explain to a buyer than an unexplained crack.

Piering is priced per pier, and the number of piers depends on how much of the foundation has moved and how much load each one has to carry. The free inspection produces a written per-pier count and total for your house.

Push piers use the weight of the structure to drive, so they suit heavier houses. Helicals are torqued in and do not need structural weight, so they suit lighter structures, additions, and porches. We choose based on your soil and load, and we explain the reasoning in the estimate.

Sometimes fully, often partially. Attempting maximum lift on a house that has been settled for decades can crack finishes that have long since adjusted. We tell you what is achievable and what we would recommend stopping at.

We dig by hand rather than bringing in equipment, specifically to limit the damage. Excavation is localized to each pier location.

Steel piers bearing on load-bearing strata are a permanent repair, and the warranty is lifetime and transferable.
