*Prices shown are estimates for the Washington DC, Maryland, and Virginia area. Foundation repair costs vary widely based on soil conditions, structural engineering findings, and the extent of damage. A professional inspection is required for an accurate quote.
Our free foundation repair cost calculator estimates your project based on the type of problem, your foundation, and the size of your home. In the Washington DC, Maryland, and Virginia area, sealing hairline cracks starts around $500, major crack repair averages $1,500, and structural problems like settling or bowing walls typically run $4,000–$10,000+ once support piers are involved.
Foundation problems get more expensive the longer they wait. A hairline crack that costs a few hundred dollars to seal today can become a settling issue requiring $1,200-per-pier underpinning in a few years — so early inspection is the cheapest repair you can buy.
| Repair | Typical Cost |
|---|---|
| Hairline crack sealing | $500 |
| Major crack repair | $1,500 |
| Water damage / leak repair | $3,000 |
| Settling / sinking (underpinning) | $4,000 + $1,200 per pier |
| Bowing wall stabilization | $5,500 |
| Drainage correction | $1,800 |
| Basement waterproofing | $2,500 |
| Crawl space encapsulation | $3,500 |
| Structural engineer report | $500 |
Most foundation repairs cost between $500 and $10,000. Simple crack sealing sits at the low end, while structural underpinning with steel piers — the fix for a settling foundation — averages $4,000 plus about $1,200 per pier installed.
Usually not. Settling, soil movement, and normal wear are excluded from nearly all policies. Coverage generally applies only when the damage comes from a covered peril — a burst pipe, for example. Earthquake and flood damage require separate policies.
Non-structural cracks are injected with epoxy or polyurethane from the inside. Structural cracks — wider than 1/4 inch, horizontal, or stair-stepping through block — need reinforcement such as carbon fiber straps, wall anchors, or piers, which is why a professional assessment matters.
Crack repairs take a day. Pier installation typically takes 2–5 days depending on how many piers are needed and soil conditions. Add time for engineering reports and permits on structural jobs.
