FAQ · Cost
How much does foundation repair cost?
Stabilization, not replacement, is the right call for most CT and NY foundations – and the cost picture reflects that.
Short answer
Carbon fiber straps run $500–$1,500 each; helical piers $1,500–$3,000 each. Most stabilization jobs total $3,000–$15,000. Full replacement runs $25,000–$80,000. Most CT/NY foundations don’t need replacement – that’s the contractor’s profit motive talking.
The full picture
Foundation repair pricing depends on the diagnosis, not on a per-square-foot rate. The same crack can mean a $2,000 fix or a $30,000 project depending on what’s actually moving and why. Our position after 30+ years in CT and NY: stabilize, don’t replace, wherever the engineering allows.
Common repair methods and per-unit costs
- Carbon fiber straps – $500–$1,500 per strap. Used for bowing block walls and stable vertical cracks. A typical wall needs 3–6 straps.
- Epoxy / polyurethane crack injection – $400–$900 per crack. For non-structural cracks that leak but aren’t moving.
- Helical piers – $1,500–$3,000 each. For settlement repair. Typical jobs need 4–10 piers.
- Push piers (resistance piers) – $1,800–$3,500 each. For heavier loads on deep stable strata.
- Wall anchors / I-beam systems – $800–$2,000 per anchor. For bowing or leaning walls with yard access.
Typical project totals
Carbon fiber stabilization on one bowing wall: $3,000–$7,500. Helical pier underpinning at a settled corner: $8,000–$20,000. Full perimeter helical-pier underpinning is rare and runs $25,000–$60,000. Full foundation replacement – demolish, excavate, pour, backfill – typically lands between $25,000 and $80,000 depending on the home’s size, access, and what’s above.
Why we push back on replacement quotes
Most CT block and poured-concrete foundations from the 1940s through 1990s can be stabilized for under $15,000. The 1800s fieldstone foundations common in Litchfield County and the Greenwich Backcountry are usually re-pointed and reinforced, not replaced. A contractor who walks in and immediately quotes full replacement on a wall with a single vertical crack is selling a project, not solving a problem. Get a second opinion. Every time.
Get a real diagnosis first
Crack width, direction, and movement matter more than what they look like. A hairline vertical crack in poured concrete is almost always cosmetic. A horizontal crack at mid-wall height in block is structural and urgent. The free inspection isolates which one you have before anyone quotes a number.
