What is the cost per square foot for structural repair?

Stabilization often $4–$8/sq ft; underpinning $10–$20/sq ft; wall bracing and full structural $8–$25+/sq ft.

Underpinning vs pier stabilization cost?

Pier stabilization is often $4–$8/sq ft. Underpinning is more invasive and typically $10–$20/sq ft or more.

How long does structural foundation repair take?

Stabilization 3–7 days; underpinning 1–3 weeks; full structural repair 2–6 weeks.

What is included in structural foundation repair?

Typically: engineering, excavation, piers or underpinning, wall bracing if needed, and backfill. Permits may be extra.

Does homeowners insurance cover structural foundation repair?

Usually no for settling or wear. Sudden events (e.g. landslide) may be covered. Check your policy.

How do I get the best structural repair quote?

Get 2–3 quotes from licensed structural/foundation specialists. Ensure engineering is included or recommended.

What causes structural foundation problems?

Soil movement, poor drainage, design or construction defects, and tree roots. Engineering identifies cause and solution.

How much does underpinning cost?

Underpinning typically $1,500–$3,000+ per section. Full foundation often $10,000–$30,000+.

Do I need a structural engineer?

Yes, for structural foundation repair. Engineer specifies scope and method; contractor executes.

What is the lifespan of structural foundation repair?

Quality underpinning or pier work often lasts decades. Warranties vary by contractor and method.

How much does wall bracing cost?

Wall bracing (carbon fiber or steel) typically $300–$800 per strip or more. Full wall $2,000–$8,000+.

How much does it cost to fix a bowing foundation wall?

Bowing wall repair typically $5,000–$15,000+ with braces or underpinning, depending on severity.

Carbon fiber vs steel wall repair?

Carbon fiber is thinner and often $300–$600 per strip; steel I-beams are stronger and cost more. Engineer recommends.

How do I know if I need structural foundation repair?

Signs include significant cracks, bowing walls, uneven floors, and doors/windows that won’t close. Get an engineering assessment.
