Carbon fiber, steel I-beams, and tie-back anchors. Free inspection and a written price before anything starts.
A basement wall bows because the soil outside is pushing harder than the wall can resist. That pressure does not let up on its own, and a wall that has started to move will keep moving until something takes the load.
Monday through Friday, 8:30 AM to 5:30 PM. Emergency service after hours.

What you are probably seeing
A horizontal crack across the wall
A crack running side to side, usually about mid-height, is the signature of soil pressure. It is more serious than a vertical crack and it means the wall is already flexing.
The wall is visibly leaning or bulging
Hold a straightedge against it. Any daylight in the middle is deflection, and deflection is load the wall is no longer carrying properly.
Blocks stepping or shearing
Courses of block that have slid relative to each other, or a wall that has moved in at the top, mean the failure is already progressing.
What we do about it
The right fix depends on how far the wall has already deflected. Under about two inches, carbon fiber usually holds it. Beyond that you are into steel I-beams or tie-back anchors, and anchors are the only option that can pull a wall back rather than simply stop it where it is. We measure the deflection during the inspection and tell you which category you are in.
Carbon fiber straps
Bonded to the wall to stop further movement. Low profile, no encroachment into the room, and the right answer for early-stage bowing.
Steel I-beams
Vertical beams anchored to the floor and the framing above to carry the load where deflection has gone past what carbon fiber can hold.
Tie-back wall anchors
Plates on the inside connected to anchors set in stable soil outside. The only method that can progressively straighten a wall rather than just arrest it.
Fix the water first
Hydrostatic pressure is what pushed the wall in. If the drainage and grading are not corrected, the pressure comes back. We address both.
Find out what it will actually cost
Free on-site inspection and a written estimate. No obligation to book the work.
How the free estimate works
1. We call you back
We ask what you are seeing and answer the first round of questions. If it sounds urgent, we say so rather than booking you three weeks out.
2. We come and look
Someone inspects the foundation, the crawl space or basement, and the drainage. There is no charge for the visit.
3. You get it in writing
A written estimate covering what we found, what we recommend, and what it costs. You decide from there.

A job well done! The work was performed in a timely and professional manner. Each person I spoke with seemed to genuinely care about correcting the problem and not just completing a job. I am very pleased and highly recommend Guardian Repair for any foundation issues.
Common questions
How much does bowing wall repair cost?
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.
Can a bowing wall be straightened?
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.
How urgent is this?
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.
Will carbon fiber be visible?
The straps are low profile and can be painted over. They do not take up floor space the way beams do.
Is the repair warrantied?
Yes — lifetime and transferable to the next owner.
