Foundation Repair Cost Calculator
Foundation work is not priced per square foot — the unit changes with the method. Pick the repair, enter the pier, crack, or strap count, and get a realistic cost range adjusted for severity, site access, and region.

Estimate Your Foundation Repair Cost
Choose a method and the quantity field switches to the right unit — piers, cracks, straps, linear feet, or square feet. Severity, access, and region adjust the rate.
Piers are typically spaced 5–8 ft apart along the affected wall.
$1,200–$3,000 per pier before adjustments.

Reading the result: the spread between low and high is real, not padding — the same pier job can differ by double depending on depth to load-bearing soil, which nobody knows for certain until driving starts. Treat the midpoint as a planning number and get the pier count confirmed by an engineer before comparing bids.
Foundation Repair Costs by Method
National ranges before severity, access, and regional adjustment. Note the unit column — comparing a per-pier price to a per-square-foot price is the most common way homeowners misread two bids.
Why two bids can differ by double
On a pier job the price is almost entirely the pier count, and contractors routinely disagree on how far the settlement extends. One might quote 6 piers under a single corner; another 12 along the whole wall. Both can be defensible.
The fix is to get an independent structural engineer to define the scope first, for $350–$900. Then every contractor bids the same pier count and you are comparing prices instead of opinions.
Repairing the symptom vs. the cause
Most foundation movement is a water problem. Expansive clay swells and shrinks with moisture, and downspouts dumping against the wall or a yard graded back toward the house will keep that cycle running.
Piering the structure without correcting drainage often means new cracks somewhere else in a few years. Budget for regrading, gutter extensions, or a French drain alongside the structural work — it is the cheaper half of the job and it protects the expensive half.
From Material Takeoffs to a Signed Proposal
SubcontractorHub is the platform contractors use to turn takeoffs like these into a branded proposal, financing the customer can accept on the spot, and a scheduled job — without re-entering the job anywhere. This tool is free to use; the platform is here if you want a closer look.
Foundation work is a high-ticket, financing-sensitive sale — most homeowners are not writing a $15,000 check from savings. Presenting a clear scope and a monthly payment in the same visit is what closes these jobs. See how contractor estimating software and embedded financing work together on jobs this size.
Common Questions About Foundation Repair Cost
How much does foundation repair cost?
Most repairs land between $2,500 and $15,000, but the category range is enormous because the unit of work changes with the method. Epoxy injection on non-structural cracks is $400–$900 per crack. Underpinning with steel push piers is $1,200–$3,000 per pier and usually needs 6–10, putting a real job at $8,000–$25,000. Slabjacking is $4–$12 per square foot.
How much does it cost to fix a foundation with piers?
Steel push piers run $1,200–$3,000 installed per pier and helical piers $1,400–$3,200. Spacing is roughly 5–8 ft, so a settling corner might need 4–6 piers ($6,000–$15,000) while a full side of the house could need 10–14 ($15,000–$40,000). Pier count — not house size — drives the price.
Is foundation repair covered by homeowners insurance?
Usually not. Standard policies exclude settling, soil movement, expansive clay, and poor drainage, which covers most foundation problems. It is typically covered only when caused by a named peril — a burst supply line washing out soil beneath the footing, for instance. Flood and earthquake need separate policies. Get an engineer's report first, because the cause determines coverage more than the damage does.
How do I know if a foundation crack is serious?
Width and direction matter more than length. Hairline vertical cracks under about 1/8 inch are usually cosmetic shrinkage. Treat it as potentially structural if it is wider than 1/4 inch, horizontal, stair-stepped through block or brick, wider at one end, or paired with sticking doors, sloping floors, or gaps at wall-ceiling joints. Any crack that measurably widens over a few months needs an engineer.
How long does foundation repair take?
Crack injection is often one day. Slabjacking takes one to two days and the slab is usable almost immediately. A 6–10 pier installation typically runs three to five days on site. Carbon fiber straps take one to two days. The bigger schedule risk is what surrounds the repair — engineer reports, permits, and restoring excavated landscaping.
Does foundation repair need a structural engineer?
For anything structural, yes — and it is worth the $350–$900 even when not required. An independent engineer is not selling the repair, so the report gives you a neutral scope to bid against and stops the pier count drifting between quotes. Many jurisdictions require a stamped letter to permit underpinning.

Book a Free DemoCost ranges are national planning estimates based on typical published contractor pricing and are adjusted by the severity, access, and region factors you select. Actual foundation repair pricing depends heavily on soil conditions, depth to load-bearing strata, and local labor rates, none of which can be known without a site investigation. This tool is not a substitute for a structural engineer’s assessment.
