Foundation & Structural costs
Foundation repair, underpinning, framing and the structural work nobody budgets for. Page 3 of 3.
Foundation repair cost$350 to $30,000per projectFoundation repair costs $350 for one injected crack and $7,000 to $30,000 for underpinning a settling house. The same visible crack can mean either, which is why the first $400 should buy an independent engineer.
Foundation crack repair cost$350 to $1,000eachInjecting a foundation crack costs $350 to $1,000, typically $600. The expensive question is not the injection: it is whether the crack is the problem or a symptom of something moving.
Foundation pier cost$1,500 to $4,000eachUnderpinning costs $7,000 to $30,000, typically $16,000. Push piers are $1,500 to $3,500 each and helical piers $2,000 to $4,000. Piers are priced per pier, not per foot of wall.
Bowing basement wall repair cost$5,000 to $15,000per projectRepairing a bowing basement wall costs $5,000 to $15,000. A horizontal crack along a block course is the one crack in a house that deserves a phone call today.
Basement waterproofing cost$3,000 to $10,000per projectBasement waterproofing costs $3,000 to $10,000, averaging $5,000. Interior drain tile is $50 to $120 per foot and exterior excavation $100 to $220. Do the cheap things first.
French drain cost$10 to $90per linear ftA French drain costs $10 to $90 per linear foot depending on depth and placement. Slope and an outlet decide whether it works, and both are invisible once the trench is filled.
Crawl space encapsulation cost$300 to $1,000per sq ftEncapsulating a crawl space costs $3 to $10 per square foot, averaging $5,500. In humid climates the vents code once required are actively delivering water into the space.
