Price Foundation Repair: How Bids Are Built

Foundation repair price is built in layers: unit count, unit price, engineering, permits, mobilization, and restoration. Most totals land between $4,000 and $15,000, with major work at $20,000 to $40,000. If you can read the layers, you can compare bids honestly instead of comparing the last number on the page.

The Unit Price Layer

Every method has a unit. Push piers run $1,000 to $3,000 each. Helical piers run $700 to $2,500 each. Wall anchors run $500 to $1,500 each. Carbon fibre straps run $400 to $1,200 each. Crack injection runs $400 to $1,200 per crack. Slab lifting runs $3 to $12 per sq ft.

The unit price is where most homeowners focus, and it is the least important number in the bid. A contractor with a low unit price and a high count can be more expensive than one with a high unit price and a conservative count, and the second is often the better repair.

The Count Layer

The count comes from the engineer’s design. Pier spacing along a wall is typically 6 to 10 feet, with additional piers at corners and concentrated loads. A 40-foot wall at 8-foot spacing needs five piers, rounded up:

40 ÷ 8 = 5

If one bid says five and another says eight, the difference is not salesmanship; it is a different design assumption. Ask each contractor to justify the count against the engineer’s report.

The Overhead Layer

Those six lines can add 20% to 40% to the headline number. A bid that omits them is not necessarily cheaper; it is less complete. The comparison that matters is the all-in total for the same scope.

A Full Price Build

A 1,900 sq ft house needs nine push piers. Here is the full build.

Piers: 9 × $2,000 = $18,000

Engineering: $1,000

Permit: $400

Mobilization: $600

Restoration at 15% of structural:

$18,000 × 0.15 = $2,700

Total: $18,000 + $1,000 + $400 + $600 + $2,700 = $22,700

That is a major repair, and it sits at the bottom of the $20,000 to $40,000 band. Note that restoration alone is 12% of the total, which is why it belongs in the budget from the start.

Price by Region

Labor rates and permit fees vary by state and metro, and soil conditions vary by lot. Expansive clay in Texas and Colorado often requires deeper piers than glacial till in the upper Midwest, and a deeper pier costs more steel and more driving time.

Coastal markets with high labor rates and tight access sit at the top of every band. Rural markets with cheap labor and easy access sit at the bottom. The same nine-pier scope can differ by 30% or more between two states, and neither price is wrong.

Season matters as well. A job priced in February for a March start often costs less than the same job priced in June for an August start, because crews are booking winter work at a discount and summer work at a premium. If the movement is not urgent, ask what the off-season price would be.

What a Low Bid Usually Omits

A bid that is 30% below the others will usually contain two or three of those omissions. Ask which ones, and price them back in before deciding.

How to Negotiate Scope

1. Get the engineer’s report first and use it as the common scope.
2. Ask each bidder to price the same unit count and depth.
3. Ask what a lower bid excludes before asking for a discount.
4. Negotiate payment terms and the overrun rate, which cost the contractor little.
5. Ask whether non-critical areas can be staged over two seasons.
6. Never trade away the pier count or the engineering to hit a budget.

Reading the Final Invoice

The final invoice should match the contract, with change orders documented and signed. Compare the pier count installed against the count billed, and confirm the refusal depths match the lift log. If the invoice includes extra piers, the change order should show the unit price agreed before excavation.

For the full estimating context, read foundation repair cost and how much foundation repair costs. If you are comparing bids from different firms, foundation repair contractors covers the contract terms that go with the price.

One final check belongs on every bid. Make sure the total is expressed in the same way across all of them: before tax or after, with permit included or excluded, and with restoration in or out. Two bids can look $3,000 apart and be identical once the presentation is normalised.
