How Much Does Foundation Repair Cost in 2025?
Foundation repair costs typically range from $2,100 to $8,400, with most homeowners spending around $4,800. Minor repairs, such as sealing hairline cracks, may cost as little as $250 to $800, while major structural work like underpinning, foundation lifting, or full stabilization can exceed $20,000+.
Your final cost depends on your foundation type, soil conditions, accessibility, and how early the issue is caught. Addressing problems promptly keeps repairs in the lower range, while delaying repairs can allow cracks and settlement to worsen — often multiplying costs several times over.

Foundation Repair Costs by Type of Repair
Different structural issues require different repair methods. Each method has its own cost range depending on soil stability, accessibility, and how much lifting or reinforcement is needed. Here’s a quick breakdown of what each repair method typically costs.
| Repair Type | Typical Cost Range | Description / What It Does |
|---|---|---|
| Mud-jacking / Slab-jacking | $550 to $1,450 | Lifts sunken concrete slabs by pumping grout or foam beneath the foundation. |
| Polyurethane Foam Injection | $900 to $2,500 | Lightweight foam used to lift concrete and fill voids with minimal disruption. |
| Piering / Underpinning (Push Piers / Helical Piers) | $1,000 to $3,000 per pier | Stabilizes and lifts sinking or shifting foundations by transferring load to stable soil. |
| Basement Waterproofing System | $2,300 to $7,300 | Adds interior drains, vapor barriers, sump pumps, or sealants to stop water intrusion. |
| Exterior Drainage Installation | $1,500 to $4,000 | Improves drainage grading and installs French drains to divert water away from the home. |
| Wall Reinforcement (Carbon Fiber / Steel Bracing) | $4,000 to $12,000 | Strengthens bowing or bulging foundation walls through structural reinforcement. |
| Crawl Space Support Beam Repair | $1,500 to $6,000 | Repairs sagging floors and failing crawl space supports with jacks or new beams. |
| Foundation Lifting / Full-Leveling | $20,000 to $23,000+ | Re-levels severely settled homes using multiple piers and structural adjustments. |
| Soil Stabilization (Grout / Polymer Injection) | $1,000 to $5,000+ | Stabilizes shifting soil beneath the foundation to prevent ongoing settlement. |
What These Repair Types Typically Address
- Mud-jacking / Slab-jacking: Lifting sunken concrete slabs
- Piering / Underpinning: Stabilizing sinking or shifting foundations
- Waterproofing: Preventing basement leaks and moisture intrusion
- Wall reinforcement: Correcting bowing or bulging basement walls
- Foundation lifting: Re-leveling severely sunken homes
Foundation Repair Costs by Problem
Not sure what repair method your foundation needs, but know what problem it may have? These are average foundation repair costs by issue:
| Foundation Problem | Typical Cost Range | Common Repair Methods |
|---|---|---|
| Hairline Surface Cracks | $250 to $800 | Epoxy injection, polyurethane sealant |
| Foundation Leaks / Moisture | $2,000 to $6,000 | Interior drain tile, vapor barriers, sump pump installation |
| Settling / Sinking Foundation | $3,000 to $10,000 | Piering/underpinning, mud-jacking, soil stabilization |
| Bowing or Bulging Basement Walls | $4,000 to $12,000 | Carbon fiber straps, wall anchors, steel I-beams |
| Drainage or Grading Problems | $1,500 to $4,000 | Regrading soil, French drains, downspout extensions |
| Soil Movement / Expansive Clay Shifts | $1,000 to $5,000+ | Soil stabilization, underpinning |

How to Interpret These Cost Ranges
- Minor issues: under $1,000 (cosmetic cracks, isolated leaks)
- Moderate issues: $2,000 to $7,000 (settling, bowing walls, recurring moisture)
- Major structural issues: $10,000+ (significant sinking, structural shifts)
If you’re unsure what problem you’re dealing with, schedule an inspection with a licensed foundation contractor or structural engineer.
What Are the Signs You Need Foundation Repair?
Spotting issues early can prevent a $250 crack repair from becoming a $10,000 structural project. Look for these common warning signs.
Early Warning Signs
- Hairline cracks in walls or floors
- Doors or windows that stick seasonally
- Slightly sloping floors
- Cracks above window or door corners
Exterior Warning Signs
- Stair-step cracks in brick or block
- Gaps between soil and your foundation
- Pooling water near exterior walls
Interior Warning Signs
- Diagonal cracks around door or window frames
- Cabinets or trim pulling away from walls
- Uneven or sunken floors
How Long Does Foundation Repair Take?
Repair timelines depend on the severity of damage, accessibility, and the method used. Most projects fall into these ranges.
- 1 to 3 days: Crack sealing, minor pier installation, interior patching
- 3 to 5 days: Wall reinforcement, waterproofing systems, multi-pier adjustments
- 5 to 7+ days: Full leveling, extensive piering, excavation-heavy work
Most repairs do not require homeowners to leave the home, though major projects may cause temporary disruption.
Foundation Repair Costs by Region and State
Foundation repair costs vary widely across the U.S. due to soil composition, climate, codes, and local labor rates. Regions with expansive clay, seismic risk, or older homes typically see higher repair bills.
Typical regional ranges:
- Southern states: $2,100 to $7,200
- Midwest and Plains: $2,500 to $8,500
- Northeast: $3,000 to $10,200
- West Coast: $3,000 to $10,200+

What Factors Affect Foundation Repair Costs?
Your final cost depends on a combination of structural, environmental, and project-specific factors. Here’s how contractors determine pricing.
1. Foundation Type
| Foundation Type | Average Cost Range | What Affects Cost |
|---|---|---|
| Basement | $5,000 to $15,000 | Requires excavation, waterproofing, and wall reinforcement |
| Concrete Slab | $3,000 to $7,500 | Repairs often need piering or slab jacking |
| Cinder Block / Brick | $3,500 to $10,000 | May require partial rebuilding |
| Pier and Beam | $2,500 to $8,000 | Easier access but frequent leveling needs |
| Stem Wall | $4,000 to $12,000 | Combination of slab and raised design adds complexity |
2. Severity of Damage
- Minor: Cosmetic cracks or small settling (less than $1,000)
- Moderate: Partial settling, moisture issues ($3,000 to $7,000)
- Severe: Structural shifts, major bowing ($15,000+)
3. Soil Conditions
Expansive clay swells with moisture, while sandy or poorly compacted soils can erode or allow sinking. Homes in active soil environments may require additional stabilization costing $1,000 to $5,000+.
4. Drainage and Moisture Control
Poor drainage is a leading cause of foundation failure. Fixes like regrading or installing French drains typically cost $1,500 to $4,000. Severe moisture problems may require basement waterproofing or sump pump installation.
5. Accessibility and Location
Sloped lots, tight crawl spaces, or concrete-heavy properties increase labor costs. Labor often accounts for 50%+ of the total project cost.
6. Home Size and Construction Materials
Larger homes and masonry-heavy builds require more materials and more extensive reinforcement. Costs typically fall between $2 to $9 per square foot.
7. Permits, Codes, and Local Regulations
Permits and required inspections usually add $75 to $500. Seismic zones, flood zones, and strict municipal codes can increase costs further.
8. Soil or Structural Engineer Reports
- Soil (geotechnical) report: $500 to $3,000
- Structural engineer report: $500 to $1,000
These reports are often required for major settlement, bowing walls, or insurance claims.
9. DIY vs. Professional Labor
Small cosmetic crack repairs can be DIY, but structural work should only be done by a licensed professional to protect your home and warranty.
Can I Do Foundation Repair Myself?
In most cases, no. DIY repairs are only appropriate for small, non-structural cracks less than 1/8 inch wide. Anything involving settlement, sinking, moisture intrusion, or bowing walls requires professional intervention.
- Safe DIY projects: Hairline crack sealing, improving drainage
- Not safe for DIY: Pier installation, lifting, structural reinforcement, waterproofing systems
Foundation work is specialized and often involves heavy equipment. Improper repairs can worsen the problem or mask symptoms until costs skyrocket.
How to Save Money on Foundation Repair
Smart planning and early action can significantly reduce your total cost. Here’s how homeowners keep their project budget-friendly.
- Address Problems Early.
A $300 crack can become a $10,000 structural repair if ignored. Schedule an inspection at the first sign of movement. - Get Multiple Quotes.
Costs vary widely across contractors. Compare at least three detailed estimates. - Bundle Related Services.
Pairing waterproofing, drainage, or landscaping work can reduce labor and equipment costs. - Check Financing Options.
