Foundation Repair Cost Calculator

Minor crack sealing can be a few hundred dollars; settling repairs commonly run $3,000 to $8,000, and major structural work can exceed $30,000.

Stair-step cracks, sticking doors and windows, uneven floors, and gaps around frames are common warning signs.

Usually not for settling or soil movement, though sudden covered events may qualify. Check your policy.

Yes. Foundation problems worsen over time and can threaten the whole structure and your home's value.

For anything beyond minor cracks, a structural engineer's report is worth the cost to confirm the right fix.

Yes, foundation repairs are almost always worth doing because structural issues worsen over time and significantly reduce a home's value and marketability. Minor crack repairs can cost a few hundred dollars, while more extensive stabilization work ranges from $5,000 to $25,000 or more. Leaving foundation problems unaddressed can lead to much costlier damage to walls, floors, and plumbing. Consult at least two licensed structural engineers or foundation specialists for an honest assessment before committing to a repair approach.

Standard homeowners insurance typically does not cover foundation damage caused by settling, soil movement, or long-term moisture issues, which are the most common causes. Coverage may apply if the damage was caused by a sudden, covered peril such as a burst pipe that undermined the foundation. Flood-related foundation damage requires a separate flood insurance policy. Review your policy's exclusions and talk to your agent to understand exactly what scenarios are covered before assuming you have protection.

Foundation repair costs vary widely based on the type and severity of the problem. Simple crack injection or sealing may cost $500 to $2,500, while piering or underpinning to stabilize a sinking foundation typically runs $10,000 to $30,000 or more for an average home. Drainage correction and waterproofing projects fall in the $3,000 to $15,000 range. Getting multiple quotes from licensed foundation contractors and ideally an independent structural engineering assessment gives you the clearest picture of what your specific situation will cost.

In most cases, homeowners can continue living in the house during foundation repairs, since the majority of the work is done from the exterior or crawl space. Some interior access may be needed for crack repairs or waterproofing, which can cause temporary dust and disruption. For major underpinning or lifting projects, your contractor will advise you if any rooms need to be vacated during specific phases. Confirm the timeline and access requirements with your contractor before the project begins so you can plan accordingly.
