How Much Do Helical Piers Cost? Madison Foundation Settlement Pricing
Quick answer: Helical piers run $1,500 to $2,500 per pier in the Madison metro. Most residential projects use 4 to 12 piers, putting total project cost between $10,000 and $30,000. The spread comes from depth-to-bearing: Verona homes over compacted till hit load at 15 to 20 feet; Waunakee homes over former marshland sometimes need 30 to 45 feet of shaft.

What you actually pay for, per pier
A helical pier is a galvanized steel shaft with one or more helical plates welded to the bottom. We torque it into the soil under hydraulic power until it hits a target torque value (which correlates to load-bearing capacity), then bolt a steel bracket between the pier head and the underside of your footing. The footing's weight transfers off the failing soil and onto the pier. From that moment on, the load travels through the pier shaft to competent soil below the active zone of clay swelling.
Your per-pier price covers the steel, the labor, the bracket, and the load test. It does not cover the access excavation if the pier location sits under a finished patio, a deck, or hardscape that has to come out first. Those are separate line items, usually $300 to $900 each, called out on the quote.
Why Verona and Waunakee dominate our helical pier call book
Verona's population roughly doubled in the 15 years after Epic Systems opened its south-side campus in 2005. The buildout that followed put thousands of homes on graded farm fields where the topsoil was scraped and the clay subgrade was compacted to suburban-tract standards rather than custom-build standards. Fifteen to twenty years later, those homes are showing up at our door with corner settlement and stair-step cracks in the block walls. Hawks Landing, Cathedral Point, and Liberty Square are the three subdivisions we run helical pier crews into most often.
Waunakee runs at the highest price-per-job tier in our service area. The reason is geology: deep organic muck and former marshland east of the village core means longer pier shafts to reach load. Castle Creek and Kilkenny Farms homes routinely need 30-foot shafts where a Verona home of the same age and footprint hits load at half that depth. Add the higher pier counts that come with whole-house settlement on weak soil, and you get the $22,000 to $30,000 projects that make up most of our Waunakee work.
Helical piers vs the other options
Underpinning is not the only fix for a settling foundation, and it is not always the right one. Two faster, cheaper options handle the cases where the damage is cosmetic or the soil movement is dormant.
| Method | Per-unit cost | When it fits |
|---|---|---|
| Helical piers | $1,500-$2,500 per pier | Active settlement, ranch homes, porch additions, lightweight structures |
| Push piers | $1,800-$3,500 per pier | Active settlement, heavy two-story homes with enough mass to drive the pier |
| Polyurethane injection (slab) | $3-$8 per square foot | Slab-on-grade settlement, garage floors, sidewalks (not foundation walls) |
| Mudjacking (slab) | $3-$6 per square foot | Older budget option for slab leveling, less durable than polyurethane |
Helical piers carry one advantage that matters for Wisconsin soils: they install in any weather. Push piers stall when the ground is saturated and the hydraulic resistance disappears. We have run helical crews on Cottage Grove cut-fill projects in February with frost still in the top two feet. The shaft drives below the frost line within the first eight feet, and the torque readings stay accurate.
What an inspection looks like before the quote
Free, no pressure, roughly 60 to 90 minutes on a typical Madison home.
- Walk the exterior. We photograph every visible crack, measure the offset across each crack with a feeler gauge, and check the lot grade with a six-foot level at the foundation perimeter.
- Walk the basement. We map cracks on the interior, check for displacement at floor-to-wall joints, and run a zip-level across the slab to confirm whether the settlement is local or whole-house.
- Pull soil context. If the home is in a zone we have worked before (Bristol Ridge in Sun Prairie, Smith's Crossing, the Bishops Bay developments), we already know the soil profile. If not, we cross-reference the Dane County soil survey before we quote.
- Quote on the spot or within 24 hours. Pier count, pier locations, project cost as a not-to-exceed number, timeline, and the engineering stamp if the scope needs one.
Local proof points: real recent projects
An Atwood-neighborhood Madison home built in 1962 came to us last spring with 1.3 inches of settlement at the southwest corner, opening a stair-step crack from the basement floor to the rim joist. Five helical piers along the south wall, 17 feet to bearing each, lifted the corner back to within a quarter-inch of original elevation. Total: $11,200, two days on site, one day for inspection backfill.
A Cottage Grove home in the Glacial Drumlin subdivision (built 2009 on cut-fill, the exact pattern we describe in our Cottage Grove service-area page) showed up at the 14-year mark with a cracked drywall seam over the front entry and a sticky front door. Eight piers along the cut-fill transition line, 22 feet average depth, $18,400 all-in. The drywall guy followed us by four weeks.
A Fitchburg job in the Quarry Ridge zone took the most engineering. The footing sat half on the dolomite shelf and half on six feet of compacted till, and the standard scope did not apply. We brought in our P.E. partner, dropped six helical piers under the till side only, and let the dolomite side carry its own load as it had been doing for 50 years. Total with engineering: $14,800.
How to read a helical pier quote
The line items that matter. Look for these. If the quote does not break them out, ask.
- Pier count and pier depth allowance. A quote that says "4 piers, depth as needed" is unbounded. A real quote says "4 piers, 25-foot allowance, $300 per additional 5-foot section if soil requires."
- Load-test method. Every pier should be load-tested to 1.5x design load before backfill. The quote should say so.
- Engineering stamp. Required by the Dane County building inspector on most structural projects. Either bundled in or called out as a $250-$400 line.
- Re-leveling included or excluded. Lifting the foundation back to original elevation is optional on some jobs and required on others. A re-leveling line item runs $500 to $1,500 across the project.
Why the price has not come down
Steel. The pier shaft and helical plates are the most expensive raw material we touch, and steel prices have not eased much off the 2022 peaks. The hydraulic torque heads that drive them are specialized equipment with limited supply. Crew training is a long-cycle problem: a good helical operator needs 18 months on the rig before we let them quote depth. None of those inputs respond quickly to demand changes, and Madison-area demand has only gone up as the Verona and Waunakee buildouts age into their failure windows.
Frequently asked
How much does one helical pier cost installed in Madison?
$1,500 to $2,500 per pier for residential underpinning in Dane County. That covers the pier itself (a galvanized steel shaft with one or more helical plates), the install labor, the bracket that bolts the pier to your footing, and the load test we run on every pier before backfilling. The spread inside that range comes down to depth-to-bearing: a Verona home over compacted till hits load at 15 to 20 feet, a Waunakee home over former marshland sometimes needs 30 to 45 feet of shaft to reach competent soil.
How many helical piers will my house need?
Most Madison-area underpinning projects use 4 to 12 piers. A localized corner-settlement job in Hawks Landing might use 4 piers along one wall. A whole-house lift in Castle Creek (Waunakee) where the entire footprint has settled into organic muck can run 12 to 16. We map the pier locations during the free inspection, and the engineer's stamp on the project plan tells you exactly how many your footing geometry requires.
What's the typical total project cost in Madison?
$10,000 to $30,000 for a residential helical pier project. The lower end is a 4-pier corner stabilization; the upper end is a 10-to-12-pier whole-perimeter underpinning with re-leveling. Add $250 to $400 if the lender requires a written engineering report. Most Madison-area projects we quote land between $14,000 and $22,000.
Are helical piers cheaper than push piers?
Per pier, helical piers run $1,500 to $2,500 versus push piers at $1,800 to $3,500. But the right question is not which costs less, it is which fits your soil. Push piers need significant structural weight above to drive the pier down, and they work best on heavy two-story homes. Helical piers torque into place under hydraulic power and work on ranch homes and porches where push piers cannot generate enough resistance. In the Madison market, helical piers handle roughly 75 percent of residential underpinning jobs.
Will my homeowners insurance cover helical pier installation?
Almost never. Standard Wisconsin homeowners policies exclude foundation settlement that results from soil movement, which is the cause of nearly every helical pier project we install. The narrow exception: if a covered event (a burst service line, a sewer backup, a major plumbing failure) directly caused the settlement, the insurer may cover the structural repair. Document the trigger event in writing before you call us, and we will work with the adjuster on the engineering side.
How long does a helical pier installation take in Madison?
Two to four days for most residential projects. Day one: excavate access pits at each pier location and expose the footing. Day two: drive the piers and install the brackets. Day three: load-test, lift where the engineer has called for re-leveling, and backfill. A larger 10-plus-pier job in Waunakee or Verona stretches to four or five days, especially if we are coordinating with a separate interior drain-tile crew on the same property.
