How much does it cost to fix a pier and beam foundation?
Pier and beam foundation repair averages $3,000 to $9,500, according to Modernize's national cost guide. A reshim can cost as little as $1,000, while a full house leveling can pass $10,000. Where you land depends on what failed under the floor, and a structural engineer is the one who tells you. Book the engineer before your deadline, then ask the seller for the repair the engineer's report names.
Key takeaways
- Underpinning and pier replacement are priced per pier, so the pier count in the engineer's report drives your total.
- An engineer's foundation inspection costs less than one replacement pier, and its report sets the scope every bid should price.
- Progressive says homeowners policies generally don't cover settling or sagging floors, so don't plan on a claim to pay for this.
What are common pier and beam foundation problems?
A pier and beam house sits on vertical piers with horizontal beams across them, over a crawl space. Modernize calls them durable but especially exposed to moisture, wood rot and shifting soil, which can lead to sagging floors.
Inspector training from the International Association of Certified Home Inspectors (InterNACHI) says piers "often settle differentially and over a long period of time, particularly when they are exposed to the weather." It lists three common causes:
- The pier footing settles or rotates. The pier drops or tilts and loses bearing capacity. The wood frame above can flex or sag, and masonry walls over it crack.
- Frost heave. A footing that's missing or too shallow lets the pier rise or tilt. This is most common under porches.
- The pier wears out. Weather, poor construction or overloading break it down. Vertical cracking and bulging are signs of an overstressed pier.
How serious is it? Large uneven settling between foundation walls and piers is the bigger worry. InterNACHI says such settlements are "more serious because they will cause movement in contiguous structural elements, such as beams, joists, floors and roofs." For older buildings with severe settlement, it warns repair "may be very costly" and recommends "the advice of a structural or soil engineer."
Your inspector may stop short of a verdict. Under the American Society of Home Inspectors (ASHI) Standard of Practice, inspectors don't have to judge whether structural parts are adequate. They also don't have to enter a crawl space with less than 24 inches of clearance, so check whether your report says the inspector went under the house. If your report also names a foundation crack or crawl space moisture, list each as its own line.
Who should look at it before your deadline?
A structural engineer. Book the engineer before any repair company, so the scope you send out for bids isn't written by the company selling the fix.
An engineer's foundation inspection costs $400 to $1,500, and Today's Homeowner says that figure changes if the damage is severe. Ask for the report in writing, naming the repair method and which piers or beams it covers. Then send that scope to two or three foundation contractors for written bids.

How do you fix a pier and beam foundation?
The fix follows the cause, not the symptom. Modernize prices the common repairs like this:
| Repair | Used for | Cost |
|---|---|---|
| Reshimming | Shims that rotted, compressed or shifted, leaving floors uneven | $1,000 to $3,500 total |
| Beam replacement | Beams that rot, crack or sag | $400 to $1,200 per beam |
| Floor joist replacement | Joists failed from moisture, pests or poor construction | $350 to $1,000 per joist |
| Pier replacement | Piers that crack, rot or sink | $2,500 to $6,000 per pier |
| Underpinning | Piers that shift or sink as the soil moves | $1,000 to $3,000 per pier |
| Crawl space waterproofing | Water getting in under the house | $3,000 to $20,000 or more |
| Full house leveling | Severe cases: the house is lifted and reset on new or reinforced supports | $5,000 to $12,000 total |
Underpinning depends on the pier type: segmented piers run around $1,000 each, steel push piers around $2,000, and helical piers around $3,000. Tight crawl spaces add labor, and wet or moldy ones often need remediation too. Permits run $100 to $500.
Most pier and beam foundations can be repaired without full replacement. Extensive rot or widespread pier failure can mean rebuilding large parts of it, and a full replacement can run $20,000 to $40,000 or more. Local prices vary too: one Dallas-Fort Worth contractor, FCS Foundation and Concrete, puts local repairs at $1,200 to $30,000, depending on how bad the damage is and what repairs are needed.
What might your repair cost?
Say the engineer finds six piers sinking and specifies steel push piers. Modernize's own example puts six piers at $2,000 each at about $12,000. Add the engineer's fee and a permit from above.
That's $12,000 + $400 + $100 = $12,500 with the lowest engineer fee and permit, and $12,000 + $1,500 + $500 = $14,000 with the highest. It leaves out beam or moisture repairs and extra labor for a tight crawl space. If the engineer adds them, price them from the contractor's written bid, not the table.
What should you ask the seller for?
Ask for the repair the engineer specifies, backed by a contractor's written bid. Name the piers or beams, the method from the report, and the bid amount, not a general request to fix the foundation. Also ask for any past engineer's report, permits, repair invoices or termite treatment records for the foundation.
Decide whether you want the seller to do the work, give a credit, or lower the price. What to ask for after a home inspection covers how this line fits with the rest of your list, and the buyer repair request letter template covers the wording.
The rest of your report needs numbers too. Kept prices every line of an inspection report for $79, usually under 4 hours, and marks foundation movement as needing a professional quote (how Kept prices).
What if the seller won't pay for it?
Counter with a credit or a lower price for the bid amount, or cancel if your contingency allows it. Your contract sets the deadline and whether you can cancel, so confirm both with your agent.
A few settled piers are one priced line on your list. If the engineer finds settlement across many piers or calls for a full replacement, and you can't get a written bid before your deadline, weigh whether to leave. When to walk away after a home inspection helps you weigh that.
How long does a pier and beam foundation last?
InterNACHI's life expectancy chart lists post and pier foundations at 20 to 65 years, against 100 years or more for poured concrete. Those figures assume regular maintenance and normal wear, and InterNACHI calls them guidelines only. Age alone won't tell you the condition. The engineer's report will.
Will homeowners insurance pay for foundation repair?
Usually not for settling. Progressive's own guidance says that, generally, "foundation cracks or settling aren't covered by your homeowners policy." Sagging floors from rotting joists are "typically not covered" either. Damage from a covered peril, such as a windstorm or a burst pipe, may be. Ask your insurance agent how your own policy reads before you count on it.
What if the engineer can't come before your deadline?
Ask your agent to request a short extension in writing. If you can't get one, send the request anyway. For the foundation, ask for a structural engineer's evaluation and the repair it calls for, at the seller's cost. Put real numbers on every other line.
While the piers wait on the engineer, upload your inspection report to Kept so the rest of your request goes in with numbers behind it.
