Foundation Repair Cost Calculator

Pick your home's shape, set its width and depth, then tap the walls where you're seeing symptoms — we'll place piers at standard 6-foot spacing to estimate a count. This is not an engineering design or a quote — it's a rough educational range so the inspection conversation makes sense.

What a pier count looks like on the ground.

Two pier holes excavated along an exterior foundation wall, laid out with a tape measure for pier placement
Pier spacing is measured along the foundation — the same math our calculator uses.
A row of hand-dug pier pits spaced along a home's foundation during pier installation
Row of hand-dug pier pits spaced along the foundation — the calculator multiplies pier count like this by your site conditions.
Square pier holes excavated along a concrete stem wall in a narrow fenced side yard
Square pier holes excavated along concrete stem wall in narrow fenced side yard — access conditions like this narrow side yard shift the estimate.
Pier hole excavated at a home's corner near the downspout to stabilize a settling foundation
Pier hole at house corner beside downspout in lawn — one of the per-pier units behind the calculator math.

Spoil mound and open pier hole beneath window along home's stem wall — every pier location adds excavation labor to the total.

What this tool does — and doesn’t

How the foundation repair cost calculator works.

The calculator estimates the one thing that drives most of a foundation repair bill: how many piers your house needs. It takes your footprint, marks the walls showing symptoms, places piers at the industry-standard 6-foot spacing along the affected runs, adds corner logic, and multiplies by Central Texas per-pier price ranges for the common methods — concrete with rebar, hybrid, and steel piers.

What moves the real number away from the estimate: your specific soil and its depth to stable strata, access (a narrow fenced side yard digs slower than an open lawn), whether an under-slab plumbing leak is part of the story, and interior piers, which need tunneling or floor access. None of that is visible from a sketch — which is exactly why the output is a range, not a quote.

Access and interior piers deserve their own sentence, because they surprise people on quotes. A pier is priced as a unit, but the digging around it is labor: a hole in an open lawn goes fast, while the same hole between a house and a privacy fence gets dug entirely by hand, and one under a deck or a pool skirt means demolition and restoration before the pier crew starts. Interior piers push this further. When the low readings sit under the middle of the slab rather than the perimeter, the crew has to reach that soil either by tunneling under the slab or by opening the floor from above, and that access work is its own line item on top of the pier itself. Depth does the same quiet work on the other end: every pier is pressed until the soil proves it is carrying the load, so a lot with deep active clay takes more pier sections and more pressing time per pier than a lot that reaches firm bearing shallow. The calculator holds all of that constant at typical values; your inspection reads the real values off your house and yard.

The exact number comes from a free on-site inspection: the elevation survey measures your floor in tenths of an inch, counts the piers your soil actually requires, and turns the range into a firm per-pier price. For the bigger picture on prices, see the Texas foundation repair cost guide.

Straight answers

Calculator questions, answered straight.

It's not about the square footage — it's about how much of the foundation actually moved. Sketch your home's footprint above, mark the walls showing cracks or sloping, and the calculator estimates pier count at 6-foot spacing and a cost range. A 2,000 sq ft house with one settled side is a very different number from one moving on three sides. The tool gives you a defensible ballpark to check any quote against; the firm number comes from a free elevation survey.
It's a planning estimate, not a quote. It's accurate on the thing that drives most of the cost — pier count from affected footage at standard 6-foot spacing — and honest about what it can't see: your specific soil, access, depth to bearing, and whether a plumbing leak is involved. Treat the output as a sanity check. If a contractor's price comes in wildly above or below it, ask why. The on-site elevation survey reconciles the rest.
Three inputs: your foundation footprint, which walls show movement, and your foundation type — slab or pier-and-beam. From there it counts piers at 6-foot spacing, adds corner logic, and applies Central Texas per-pier ranges for our common methods. It doesn't guess at soil or method, because those move the final number — which is exactly why the result is a range, not a single figure.
No. A small house moving on three sides can cost more than a large house with one settled corner. Repair cost tracks the length of foundation that moved, not the home's size. That's why a per-square-foot rule of thumb misleads people — and why the calculator asks you to mark the affected walls instead of just entering square footage.
No — and any contractor who quotes from square footage alone is guessing. The calculator gives you a range so you walk into the conversation informed. Our actual quote comes from a free elevation survey that measures your floor in tenths of an inch and counts the piers your soil truly requires — then it's a firm, per-pier number backed by a lifetime transferable warranty.
