Common signs include cracks in walls or floors (especially diagonal cracks from door and window corners), doors and windows that stick or no longer close properly, uneven or sloping floors, gaps between walls and ceilings or floors, and visible cracks in the exterior foundation wall.

Complete foundation replacement is the most expensive option. Get multiple bids with detailed engineering specifications.

Surface-only repairs without addressing underlying causes are temporary.

Unrepaired foundation problems significantly reduce home value and can prevent sales entirely. Properly repaired foundations with documented engineering and transferable warranties typically restore most or all of the lost value. Disclosure of repairs is required in most states, but documented professional repairs with warranties are viewed favorably by buyers and lenders.
