Foundation Settlement Repair: How Much Does It Cost?
Foundation settlement repair typically costs $6,000 to $25,000, as of June 2026. The final price depends on your foundation type, the extent of movement, and the repair method your structural engineer recommends.
The short answer
Foundation settlement repair typically costs $6,000 to $25,000 for a full underpinning project, as of June 2026. The price depends on foundation type, settlement extent, and the method recommended. For piering, expect $1,500-$2,500 per push pier or $2,000-$4,000 per helical pier.
Key takeaways
- Cost range: $6,000 to $25,000 for underpinning, or $1,500-$2,500 per push pier / $2,000-$4,000 per helical pier.
- Primary methods: Push piers, helical piers, and underpinning address settlement.
- Warning signs: Sticking doors, uneven floors, and wall cracks may indicate settlement.
- First step: Always have a structural engineer or foundation contractor assess this before any repair.
Settlement happens when the soil under your foundation can no longer support the weight of your home. You might notice doors that stick, floors that slope, or cracks in walls. Repairing settlement is a major structural project, and costs can vary widely. This guide breaks down the typical ranges, so you know what to expect when you start getting quotes.
How much does foundation settlement repair cost?
The total cost for foundation settlement repair depends on the repair method and extent of the damage. For a full underpinning project, you are likely looking at $6,000 to $25,000 as of June 2026. Smaller spot repairs with piers may cost less, but always budget for the possibility of hidden damage.
- A single push pier costs between $1,500 and $2,500, as of April 2025.
- Helical piers run $2,000 to $4,000 per pier, as of March 2026.
- Underpinning costs $300 to $600 per linear foot, covering the full perimeter or a large section.
- Most contractors space piers 6 to 8 feet apart along the affected wall.

What repair methods fix foundation settlement?
Contractors fix settling foundations by transferring the weight of your home down to stable, load-bearing soil or bedrock. The right method depends on your foundation type, soil, and settlement pattern. Here are the most common approaches.
- Underpinning extends the foundation deeper into stable ground and is used for whole-foundation settling.
- Push piers are hydraulically driven steel pipes that lift and stabilize lighter structures.
- Helical piers screw into the ground and handle heavier loads or deeper soil issues.
- For slab-on-grade settlement, mudjacking or polyjacking can fill voids under the slab, but they do not address deep foundation movement.
- Only a licensed structural engineer can recommend the right method after inspecting your home. Use the Quote Checker to compare proposals.
What factors affect the cost of settlement repair?
Several variables drive the final price of a settlement repair project. Understanding these will help you evaluate quotes and avoid sticker shock.
- Extent of settlement: A single spot may need only a few piers, while whole-home settling requires extensive underpinning.
- Foundation type: Basement, crawl space, and slab-on-grade each require different access and equipment.
- Access difficulty: Tight crawl spaces, finished basements, or heavy landscaping add labor hours.
- Soil conditions: Deeper or rockier soil means longer, more expensive piers.
- Number of piers: A typical 20-foot wall needs 3 to 4 piers at 6-8 feet spacing; longer walls drive up the count.
- Our Cost Calculator adjusts for these factors to give you a personalized estimate.
What does a bad settlement repair quote look like?
Not all foundation repair quotes are created equal. Watch for these red flags that often signal a high-pressure sales tactic or an unsuitable repair plan.
- A per-pier price above the sourced range (over $2,500 for push piers or $4,000 for helical) without clear justification.
- A lifetime warranty used as a sales tool; no repair can guarantee lifelong performance.
- A same-day-only discount that pressures you to sign before getting other opinions.
- A method that doesn't match your settlement pattern, like push piers for a home that needs deep helical support.
- The contractor cannot provide a structural engineer's report or refuses to explain soil analysis.
- Before you commit, run the numbers through the Quote Checker to flag inflated bids.
Can I fix foundation settlement myself?
Foundation settlement is a major structural issue. The repair methods involved require heavy equipment, deep excavation, and engineering expertise. DIY is not an option here.
- Push piers, helical piers, and underpinning must be installed by licensed professionals with calibrated hydraulic equipment.
- Epoxy injection for minor, non-structural cracks is the one exception a homeowner can attempt with a kit, but it does not fix the underlying settlement.
- Attempting to jack up your own foundation can cause irreversible structural damage and void your insurance.
- Always have a structural engineer or foundation contractor assess the settlement first, and leave the repair to bonded pros.
- For crack-only concerns, see our Crack Severity Guide to learn when monitoring is enough.

| Underpinning (per linear foot) | $300 to $600 (June 2026) | Whole-foundation settlement |
|---|---|---|
| Push piers (per pier) | $1,500 to $2,500 (April 2025) | Lighter structures, spot support |
| Helical piers (per pier) | $2,000 to $4,000 (March 2026) | Heavy loads, deep soil |
| Mudjacking (per sq ft) | $3 to $6 (March 2026) | Slab-on-grade settlement only |
| Polyjacking (per sq ft) | $5 to $25 (March 2026) | Slab-on-grade settlement, lighter fill |
Questions this page answers
How do I know if my foundation is settling?
Look for sticking doors, uneven floors, cracks wider than 1/4 inch in walls or brick, and gaps around windows. If you see these signs, have a structural engineer or foundation contractor assess this.
Is foundation settlement repair covered by insurance?
Standard HO-3 policies typically exclude gradual foundation settling and earth movement. Confirm your own policy's language with your insurer.
How long does settlement repair take?
Most piering projects take 2 to 5 days. Full underpinning can stretch to several weeks depending on the size of the job and access.
Can I stay in my home during repairs?
Usually yes, but expect noise, vibration, and limited access to parts of the home. Discuss this with your contractor before the project starts.
What is the difference between push piers and helical piers?
Push piers are driven hydraulically into load-bearing soil. Helical piers are screwed in and are better for heavier loads or deeper soil. Both support the foundation.
Will settlement repair stop future settling?
When piers or underpinning reach stable soil or bedrock, they arrest current movement. However, extreme drought or flood can still shift soil. Monitor your foundation annually.
How many piers will I need?
Typical spacing is 6 to 8 feet along the affected wall. A 20-foot wall may need 3 to 4 piers. The exact count depends on the soil report and structural engineer's design.
Should I get multiple quotes?
Yes. Get at least 2 to 3 quotes from licensed foundation contractors and compare methods, warranties, and payment schedules before you decide.
Foundation settlement repair is a significant investment, typically $6,000 to $25,000 for a full underpinning project as of June 2026. The right method and a fair price start with an in-person assessment by a licensed structural engineer.
