What does foundation repair cost?

The answer

$2,500 - $8,000 covers many foundation repair and basement waterproofing jobs, while structural piering, wall anchors, major drainage, or crawlspace encapsulation can run $8,000 - $30,000+.

Small crack injections are often much less. The expensive part is not the crack itself; it is whether water, soil pressure, settlement, or structural movement is still active.

What moves your price

Movement vs. moisture

A dry hairline shrinkage crack prices differently from active settlement, bowing walls, or recurring water pressure after storms.

Access and finish level

Unfinished concrete is cheaper to inspect and repair than finished basements, tight crawlspaces, decks, patios, or landscaping that block access.

Drainage scope

Gutters, grading, exterior drains, interior drains, sump pumps, and discharge lines all change the quote. The right fix depends on where the water is entering.

Structural review

If floors are sagging, walls are bowing, or cracks are widening, budget for a more careful inspection and possibly an engineer's letter before major work.

Do I need a sump pump or a French drain?

A sump pump removes water from a collection basin; a French drain collects and moves water toward an exit point. Basement systems often need both: an interior drain routes water to the sump, and the sump pumps it outside. Combined systems commonly cost $3,000 - $12,000+.
