Foundation settlement repair is for a house where part of the foundation has sunk. The usual fix is to support the footing on deeper, firmer soil with steel piers. This page explains push piers, one of the two common pier types, and how they compare with helical piers.
Signs a foundation is settling
Manufacturer Foundation Supportworks lists these signs of uneven settlement [1]:
- Stair-step cracks in exterior brick
- Gaps around door and window frames
- A gap opening between a floor and a wall, or between a wall and the ceiling
- A chimney pulling away from the house
The same source says soil is usually behind it. Clay soil gets soft when wet and shrinks during long dry spells, and poorly compacted fill under a lot can compress under a house's weight [2].
How push piers work
HomeGuide explains that push piers use the weight of the structure to hold them in place and are pushed into the ground "like a nail." They can't be installed at an angle [3]. Its comparison table lists push piers as suited to clay soil, rocky soil and shallow bedrock, and to heavier buildings with poured concrete footings and walls [3]. It also notes push piers may put stress on the foundation, while helical piers don't [3].
Foundation Supportworks says its push pier system is designed to stop further settlement, help close cracks and improve how doors and windows work, and may lift the home toward its original level [4]. Treat that as the manufacturer's claim and ask your contractor what result to expect.
Push piers compared with helical piers
| Push piers | Helical piers | |
|---|---|---|
| Installed by | Pushing, using the house's weight [3] | Screwing in with hydraulic equipment [3] |
| Relative cost | Lower ($) [3] | Higher ($$) [3] |
| Typical fit | Heavier homes with poured footings [3] | Lighter structures and homes without concrete footings [3] |
What settlement repair costs
National figures, not local quotes:
- Hydraulic piers: $1,000 to $3,000 per pier, from the materials table in Angi's foundation repair guide (updated Oct 26, 2026) [5]
- Home settling overall: $5,000 to $25,000 (Angi) [5]
- Minor settlement with 2 to 4 piers: $2,000 to $12,000. Moderate settlement with 5 to 8 piers: $6,000 to $25,000 (HomeGuide, updated Nov 26, 2024) [6]

Wisconsin rules to know
Footings must sit below the frost line or at least 48 inches below grade, whichever is deeper [7]. Digging near the foundation requires notice to Diggers Hotline at least 3 working days ahead [8]. In De Pere, a permit is required before repairs and alterations, and the city says one may be needed when replacing or moving columns and beams [9].
FAQ
Is some settling normal?
Angi says nearly all foundations have small cracks from normal settlement, but sinking foundations and large structural cracks are a different matter [5]. A foundation inspection can sort out which you have.
Do I need a soil report?
Not always. Angi says a geotechnical soil report costs $500 to $3,000 and can help pinpoint the right fix when the cause isn't obvious [5].
Will insurance cover settlement?
Usually not. Wisconsin's Office of the Commissioner of Insurance lists neglect and earth movement among common homeowners policy exclusions, and says exclusions vary by company [11]. The Insurance Information Institute adds that policies don't cover damage from lack of maintenance [10]. Read your policy and ask your agent.
