Foundation repair cost guide
Foundation repair scope and pricing — from crack injection ($500–$1,500) to full replacement ($25k–$60k+). Soil type, access difficulty, engineering and permits, waterproofing scope, and how to spot a bad bid.

Four repair types, four price ranges
**Crack injection** ($500–$1,500): polyurethane or epoxy filling of hairline cracks. Best for non-structural cracks in poured-concrete foundations. **Pier-and-beam stabilization** ($5,000–$15,000): steel or concrete piers driven into stable soil to lift and support a sinking foundation. Typical residential job uses 6–12 piers. **Exterior waterproofing** ($3,000–$10,000): excavation around the foundation perimeter, membrane installation, French drain, sump pump. **Full foundation replacement** ($25,000–$60,000+): rare but real for severe settling or basement-conversion projects.
Soil and climate set the baseline
Expansive clay soils (Texas, Oklahoma, central California) cause more foundation movement than sandy or rocky soils. Cold-climate freeze/thaw cycles do the same. Houston foundation work is more common AND more competitive — labor 15–20% below national average. Northern cities (Chicago, NYC) charge 20–30% above for the same job.
Linear feet × access difficulty
Pier cost scales per linear foot of foundation wall being stabilized. A 20-foot wall job in an open yard with standard setback runs $5,000–$15,000. Tight side yards, landscaping that must be removed and replaced, or basement access can double labor cost — get site access documented in the contract.
You need an engineer report
For ANY piering or replacement work, get a structural engineer report ($400–$1,200) BEFORE getting bids. The report defines the actual problem, the required scope, and gives you a baseline to evaluate contractor bids. Without it, you're trusting the contractor to diagnose AND treat — the financial incentive is obviously wrong.
Waterproofing: outside vs inside
Exterior waterproofing (excavation, membrane, drainage) is the proper fix — $5,000–$10,000 typical. Interior solutions (epoxy crack sealing, sump pump, interior drain board) are 30–60% cheaper and may treat the symptom but not the cause. For finished basements at real risk of repeat flooding, do exterior. For occasional minor seepage, interior may be enough.
Always verify with a local contractor
