How much does foundation repair cost?

Foundation repair costs $2,100 to $7,500 on average, depending on the severity and method used. Minor crack repairs start at $500, while major structural repairs with helical piers or underpinning can exceed $15,000.

How do I know if I need foundation repair?

Common signs include cracks in walls or floors wider than 1/4 inch, doors and windows that stick or won't close properly, uneven or sloping floors, gaps between walls and ceiling or floor, and visible cracks in the exterior foundation.

What are the main foundation repair methods?

The five main methods are: steel push piers, helical piers, concrete pressed pilings, slabjacking/mudjacking, and epoxy/polyurethane crack injection. The right method depends on your foundation type, soil conditions, and severity of damage.

Does homeowner's insurance cover foundation repair?

Standard homeowner's insurance typically does not cover foundation repair caused by settling, shifting soil, or normal wear. However, if the damage was caused by a covered peril like a burst pipe, it may be partially covered.

Warning Signs

8 Signs You May Need Foundation Repair

Catching foundation problems early saves 40-60% on repair costs. Here's what to look for around your home.

Diagonal cracks above doors or windows

Stair-step cracks in brick or drywall at 45-degree angles signal differential settling.

Doors or windows that stick

When frames shift out of square, it's usually the foundation moving underneath.

Gaps between walls and ceiling

Visible separation where walls meet floors or ceilings indicates structural movement.

Uneven or sloping floors

More than 1" slope per 20 feet needs professional attention.

Bowing or leaning basement walls

Horizontal cracks with inward bowing means hydrostatic pressure. Can become urgent fast.

Chimney tilting away from house

Chimneys are heavy and isolated. They show foundation movement before the rest of the house.

Exterior cracks wider than 1/4"

Hairline cracks are normal. Anything wider — especially if growing — needs a professional look.

Wet crawl space or basement water

Water intrusion can be a symptom of foundation cracks or cause future soil erosion.

FAQ

Foundation Repair Questions

Straight answers from our research team.

Foundation repair costs $2,100 to $7,500 on average. Minor crack repairs start at $300-$800, while major structural work with steel piers can run $8,000-$15,000+. The biggest cost factors are the repair method required, number of piers/pilings needed, accessibility, and local labor rates. Always get at least 3 quotes — we regularly see 30-50% price differences between contractors for the same job.

Not every crack means you need repair. Hairline cracks less than 1/8" are usually cosmetic (normal settling). Get a professional inspection if you see: cracks wider than 1/4", doors/windows that suddenly stick, sloping floors, or gaps between walls and ceilings. Many contractors offer free inspections — but be aware they have an incentive to sell. For an unbiased assessment, consider hiring a licensed structural engineer ($300-$600) before committing to repairs.

Yes, when done correctly. Steel push piers and helical piers reach stable soil or bedrock, providing a permanent solution that most manufacturers warranty for life. Concrete pilings and mudjacking are less permanent — they rely on surface soil stability and may need re-treatment in 5-10 years in expansive clay soils. The key is matching the right method to your specific soil conditions and foundation type.

This is a common fear, but it's usually the opposite. Unrepaired foundation issues can reduce home value by 10-15%. A completed repair with a transferable warranty can actually restore most or all of that value. The key is documentation: keep all inspection reports, engineering assessments, and warranty paperwork.

Usually no. Standard homeowner's insurance excludes "earth movement" — which covers most foundation settling and soil-related damage. However, if a covered event caused the damage (e.g., a plumbing leak that eroded soil), the resulting foundation damage may be covered. Check your policy for "accidental discharge" coverage. Some insurers offer optional foundation endorsements, typically $50-$150/year.

Most residential foundation repairs take 1-3 days. Crack injections can be done in a few hours. Pier installation for a typical home (8-12 piers) takes 1-2 days. Complex jobs may take a week or more. You can usually stay in your home during repairs — the work is mostly exterior.
