Structural repair costs

The national average is close to useless on its own, because "foundation repair" covers everything from a tube of epoxy to lifting a house off its footings. Use the by-method and by-problem numbers instead.

By method (Fixr, 2026): crack sealing or epoxy injection $200-$1,000; mudjacking or slab jacking $500-$1,900; sealing and waterproofing $2,400-$7,000; carbon fiber reinforcement strips $4,000-$12,000; tiebacks $5,000-$15,000; underpinning or piering $10,000-$40,000; house lifting $20,000-$30,000. This Old House prices piering at $1,000-$3,000 per pier, which is the number to ask about, since pier count is what moves the bid.

By problem (Fixr, 2026): a foundation crack $200-$1,000; a foundation leak $2,000-$10,000; a bowing wall from hydrostatic pressure $4,000-$15,000; sinking or uneven settling $4,500-$25,000. By foundation type: slab $1,000-$10,000, pier and beam $2,000-$15,000, crawl space $2,500-$12,000, basement $2,500-$25,000.

Budget separately for diagnosis. This Old House lists a structural engineer report at $500-$1,000 and a soil report at $500-$3,000, and suggests holding $1,000-$2,500 in contingency for what gets found once the ground is open. Paying for a soil report before a five-figure repair is usually money well spent.
