What does foundation repair cost?
$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.
Cost breakdown
Foundation crack injection
$500 - $1,500Common for non-structural leaking cracks in poured concrete
Basement interior drainage / sump
$3,000 - $10,000+Perimeter drain, sump basin, pump, and discharge work
Crawlspace vapor barrier
$1,500 - $5,000Basic moisture control, not full sealed encapsulation
Crawlspace encapsulation
$5,000 - $15,000+Sealed liner, air sealing, drainage, and dehumidification
Wall anchors / braces / piers
$5,000 - $30,000+Structural stabilization; engineering may be needed

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+.
Read cost guideHow much do helical piers cost?
Helical piers often cost $1,000 - $3,000+ per pier, and total foundation underpinning projects commonly land around $10,000 - $30,000+. Engineering, access, depth, number of piers, and lifting goals drive the final price.
Read cost guideHow much does basement waterproofing cost?
Basement waterproofing often costs $3,000 - $10,000+. A single crack injection may be $500 - $1,500, while interior drain tile with a sump commonly runs $4,000 - $12,000+ depending on basement size and access.
Read cost guideHow much does crawlspace encapsulation cost?
Crawlspace encapsulation often costs $5,000 - $15,000+. A basic vapor barrier may be $1,500 - $5,000, but full encapsulation with drainage, sealing, insulation, cleanup, and a dehumidifier costs more.
Read cost guideHow much does foundation crack repair cost?
A single non-structural foundation crack injection often costs $500 - $1,500. Exterior crack repair can run $2,000 - $8,000+, and cracks tied to bowing, settlement, or wall movement can become $5,000 - $20,000+ stabilization projects.
Read cost guideHow much does foundation repair cost?
Many foundation repairs cost $2,500 - $8,000. Simple crack injections can be $500 - $1,500, while piering, wall anchors, major waterproofing, or crawlspace structural work can reach $10,000 - $30,000+.
Read cost guideHow much does pier and beam foundation repair cost?
Pier and beam foundation repair often costs $2,500 - $12,000+. Simple shimming or isolated pier repair can be less, while beam replacement, joist repair, moisture damage, drainage, and crawlspace encapsulation can push projects much higher.
Read cost guideWhat should I do about a bowing basement wall?
A bowing basement wall should be inspected before it is patched or finished over. Repairs commonly range from $4,000 - $15,000+ for anchors, braces, carbon fiber, or drainage relief, and severe movement can cost more.
Read cost guideWhat should I do about crawlspace moisture or mold?
Crawlspace moisture or mold usually means water, humidity, poor drainage, failed vapor barrier, or ventilation/conditioning problems need to be fixed. Cleanup and moisture control can cost $1,500 - $15,000+ depending on damage and whether encapsulation is needed.
Read cost guideWhy does water seep into my basement after rain?
Water seeping into a basement after rain usually comes from poor exterior drainage, a leaking foundation crack, window well problems, sump failure, or hydrostatic pressure at the wall-floor joint. Fixes can range from $0 - $500 for downspout/grading work to $3,000 - $12,000+ for drainage and waterproofing.
