Foundation repair cost: what you'll pay and why

How much does foundation repair cost?

Published national figures, by type of repair:

These are national ranges, not local quotes. Depending on your area and what your house needs, you could pay well above or below them.

Foundation settling repair cost

The more piers a job needs, the higher the price. Each one adds steel, a bracket, equipment and labor. HomeGuide’s ranges by number of piers:

Source: HomeGuide, underpinning cost (November 2024).

Most quotes for piers include the piers, brackets, equipment and standard labor. Daniel wouldn’t expect one to include a report from an independent engineer, permits, a soil investigation, drainage, digging in difficult conditions, interior repairs or landscaping. If rock or soil conditions call for deeper piers, the price can go past these ranges.

That job’s approximate breakdown, rounded (Virginia, 2026):

The first line works out to $3,000 per installed pier. It doesn’t include an extended soil investigation, surprises at depth, pipe replacement or restoring the whole house. If another quote just said “six piers, $18,000,” Daniel would want to know about all of that before comparing the two.

Slab lifting is a different job. Mudjacking and foam lifting are for slabs, like a basement or garage floor, that have lost support underneath. They won’t stabilize the footings that carry the house. See foundation settling for when each method makes sense.

Foundation crack repair cost

Injecting a crack from inside costs about $350 to $900 with polyurethane and $400 to $950 with epoxy, and digging outside to patch it about $1,500 to $4,500 (FoundationSage, July 2026). Those ranges usually include materials and labor, not an engineer or a permit.

Polyurethane and epoxy do different jobs. Polyurethane is mainly used to stop water. Epoxy glues the two faces of the concrete back together, when conditions allow. If the foundation is still moving, an injection won’t repair it. See foundation cracks to work out what kind of crack you have.

Bowing wall repair cost

Bowing walls are priced by the method and the length of wall. HomeGuide lists these figures per linear foot of wall, installed (October 2025):

These are prices per linear foot of wall, not per anchor or per strap. Daniel wouldn’t turn one into the other without working out how many anchors or straps the wall needs. He also wouldn’t give different ranges based on the state the house is in. A tall wall, hard access outside, saturated soil or an expensive finish can raise the price far more. For per-unit prices and when each method works, see bowing basement walls.

Crawl space foundation repair cost

HomeGuide’s national figures (February 2026) put crawl space foundation repair at $2,500 to $8,000 for most jobs, about $1,000 to $2,000 per pier replaced in a pier-and-beam house, and $1,500 to $4,000 to replace a beam. Those include materials and normal labor, but not necessarily engineering, permits, hidden damage or moisture work. For Virginia ranges on posts, beams, joists and leveling, see crawl space encapsulation cost.

I’d want drainage, water discharge, the vapor barrier and the dehumidifier listed as separate lines on a quote. Many crawl spaces in North Carolina and Tennessee have very tight access, sloped yards and long humid seasons. I wouldn’t encapsulate a crawl space without knowing where the water gets in. And encapsulation won’t fix a support that has sunk.

That job’s approximate breakdown, rounded (North Carolina, 2026):

What raises the price

Daniel’s list, from what weighs most:

1. Number of piers, or how much underpinning. Each extra unit adds equipment, steel, brackets and time.
2. Real depth and required capacity. Going through deep fill or hitting rock isn’t the same as a routine install.
3. Access. Hand digging, patios, porches, slabs, buried utilities and tight spaces.
4. Work before or alongside the repair. Shoring, drainage, footing repairs, pipes or washed-out soil.
5. Lifting and putting things back. Controlled lifting is delicate, and plaster, masonry, windows, landscaping and paving are often billed separately.
6. Engineering, soil testing and permits. Small next to the cost of piers, but they define the job and make it legal.

He always asks for the price with depth included, the price per extra foot, what the quote assumes about access, and what happens if the piers don’t reach their design load.

Engineer and permit costs

Angi (August 2026) puts typical structural inspections at $350 to $800. These are fees for the service only, with no repair materials or labor. Daniel’s figures are national references and may not match prices in your county.

Permits depend on where you live. For underpinning, Angi lists $200 to $1,000 for the permit. Fairfax County, Virginia, lists foundation repairs among the residential work that needs a permit. In North Carolina, many repairs under $40,000 don’t need a permit, but repairing or replacing load-bearing structures does, whatever it costs (G.S. 160D-1110 (opens in a new tab)). Check with your local building department before work starts.

Does homeowners insurance cover foundation repair?

If it’s settling, probably not. Standard homeowners policies generally exclude foundation cracks, settling and damage from shifting soil. Damage from a covered event, such as a sudden burst pipe, may be covered, but that doesn’t mean the policy will pay to repair the foundation itself. It depends on the cause, the exclusions and what the adjuster finds. Check your own policy; this isn’t legal advice.

Two states have programs for damage from old mines:

• Pennsylvania offers Mine Subsidence Insurance through its Department of Environmental Protection, for damage tied to abandoned underground coal and clay mines. It doesn’t cover sinkholes from limestone. The program says it has paid more than $30 million in homeowner claims since 1961.
• Ohio has a mine subsidence insurance fund. Coverage is mandatory in 26 counties and optional in 11, up to $300,000 or the dwelling’s insured amount, whichever is lower.

Neither covers ordinary settling.

What the warranty covers

Daniel separates three things: a warranty on the product, a warranty on the installation, and a promise about how your house will perform. They aren’t the same. A pier warranty may cover the area under those piers and still exclude the rest of the foundation, finish work, drainage problems or the cost of digging to reach the piers.

For slab lifting, he’d ask how long the lifted area is warranted, whether it gets injected again if it settles, and what’s excluded: leaks, washed-out soil, new loads.

A warranty may or may not transfer when you sell, depending on the contract. Some require a request within a set time and charge a fee; others don’t transfer at all. Get it in writing: what’s covered, marked on a drawing, for how long, who honors it if the company goes out of business, how to file a claim, what’s excluded, whether they’ll reinspect and whether it transfers.

How to compare foundation repair quotes

Warning signs Daniel looks for in a quote:

• A number of piers with no layout plan, loads or engineering basis.
• “Your house is sinking,” based on one drywall crack.
• No distinction between a floor slab and the foundation that carries the house.
• No depth included, and no price per extra foot.
• Helical piers with no stated system, brackets, torque or capacity criteria, or installation record.
• Push piers with no explanation of how the footing will handle the force.
• No clear statement of whether the job will stabilize, partly lift or fully level the house.
• A leak or drainage problem left out, still feeding water to the foundation.
• Engineering, soil testing, permits, digging, finish repairs and warranty not listed as included or excluded.
• A “lifetime warranty” with no document, exclusions or transfer rules.
• A contract with no plan for unexpected soil conditions or change orders.

Helical piers should come with product documentation, evaluated under ICC-ES AC358 where it applies. A pier that reaches a certain depth doesn’t automatically have a certain load capacity.
