Foundation Type
Your options for foundation repairs will vary based on your home’s foundation type, whether it’s a basement, a concrete slab, cinder blocks, bricks, or a crawl space. Prices for each foundation type also depend on the type and extent of damage since there’s no single solution for all foundation problems.
With most homes in Kansas City having basements, homeowners will need to budget for the higher cost of repairing basement foundations compared to slab foundations. However, the severity of a foundation issue is generally the biggest cost factor of all.

|---|---|---|
| Concrete slab | $700–$16,000 | Low |

Does Foundation Repair Affect Home Value?
A foundation that is in good condition can add substantially to a home's value. By ignoring foundation issues, homeowners risk allowing their homes to become uninhabitable. Unfortunately, a crumbling or cracked foundation could prevent you from selling your home because lenders generally will not provide mortgages for homes that cannot pass foundation inspections.
