Foundation Repair Services
Reviewed 2026-07-30
Foundation repair stabilizes settlement, bowing walls, and structural movement. Crews use engineered methods such as piering, wall anchors, or slab jacking, chosen to match the cause found during inspection.
Symptoms foundation repair solves
- A structural engineer has confirmed active settlement or wall movement
- Foundation walls are visibly bowing or leaning inward
- Doors and windows have progressively worsened sticking
- Floors have a measurable slope confirmed by a level survey
- Stair-step cracks in brick or block are widening over time
- Gaps have opened between the foundation and porch, garage, or addition
When to book foundation repair
- After a structural engineer's report confirms the cause and recommends a specific repair method
- Before listing a home for sale if foundation issues were previously identified
- As soon as monitoring shows a crack is actively widening rather than stable
- Before finishing a basement over a foundation with known but unaddressed issues
What happens during foundation repair
- Engineer's report and soil conditions determine the appropriate repair method (piers, wall anchors, carbon fiber straps, or slab jacking)
- Contractor pulls required permits, since structural foundation work is inspected by the local building department
- For pier systems, excavation reaches load-bearing soil or bedrock and hydraulic piers are driven and load-tested
- For bowing walls, wall anchors or carbon fiber strips are installed to stabilize and, where possible, gradually straighten the wall
- Drainage improvements (grading, French drains) are typically recommended alongside structural repair to prevent recurrence
- Final inspection verifies the repair meets code and the engineer's specifications
Foundation Repair methods and approaches
Push piers or helical piers
Steel piers are driven to load-bearing strata beneath the foundation and used to stabilize and, in many cases, lift settled foundation sections back toward original position.
Wall anchors
Steel anchors are installed in the yard and connected through the foundation wall to counteract inward bowing pressure from expansive soil, then can be tightened over time to straighten the wall.
Carbon fiber reinforcement
For walls with early-stage bowing (typically under 2 inches of deflection), carbon fiber straps are epoxied to the interior wall surface to prevent further movement without excavation.
Slab jacking / mudjacking or polyurethane foam injection
Used to lift settled concrete slabs (garage floors, walkways, porches) by injecting material beneath the slab to fill voids and raise it back to level.
What drives foundation repair pricing
- Repair method (piers are more expensive than carbon fiber straps for early-stage issues)
- Number of piers or anchors needed, determined by engineering calculations
- Excavation depth required to reach stable soil
- Whether drainage correction is bundled with structural repair
- Accessibility around the foundation (landscaping, hardscaping, additions)
- Warranty length and whether it's transferable to future homeowners
Questions to ask your foundation repair contractor
- What method are you recommending, and is it based on an independent engineer's report?
- How many piers or anchors does the engineering calculation call for?
- Is the warranty transferable if I sell the house?
- Will you also address the drainage issue that may have caused this?
- What permits will be pulled, and will the work be inspected by the local building department?
- Can you provide engineering documentation I can use for future resale disclosures?
Foundation Repair safety and licensing
- Never skip the independent structural engineer step — get a diagnosis before hiring a repair contractor, since diagnosing your own product creates a conflict of interest.
- Confirm any pier or anchor system is installed to written engineering specifications, not just a contractor's standard package deal.
- Ensure permits are pulled for foundation work — unpermitted structural repairs create major disclosure and insurance problems at resale.
Foundation Repair questions homeowners ask
How much does foundation repair typically cost?
Carbon fiber wall stabilization runs about $350-$1,000 per strap; a full pier system to stabilize settlement typically runs $1,000-$3,000 per pier, with whole-house jobs ranging from $5,000 to $30,000+ depending on severity.
Do I need an engineer before hiring a foundation repair contractor?
Yes — an independent structural engineer's evaluation avoids the conflict of interest of having the same company diagnose the problem and sell you the repair.
How long do foundation pier repairs last?
Properly installed and engineered pier systems are designed to last the life of the structure, and most reputable contractors offer transferable warranties of 25 years or longer.
