Frequently Asked Questions
Get 3+ quotes from different types of providers — specialty contractors, GCs with foundation experience, and ideally an independent structural engineer for an unbiased assessment first. Look for 10+ years in business, proper licensing, and transferable warranties. Check BBB, Google reviews, and ask for local references. Be wary of any provider that only offers one solution regardless of the problem.
An independent structural engineer ($400–$800) can diagnose problems without sales bias and design appropriate solutions. This is recommended for complex issues, if contractor assessments differ significantly, or if you're buying a home with foundation concerns. Their report is valuable for insurance, selling, or legal matters.
Quality foundation work should come with a 25-year to lifetime transferable warranty. 'Transferable' means it passes to new owners, protecting your home's value. Read what's actually covered—some warranties exclude labor or require maintenance. Avoid contractors offering only 5–10 year warranties on major structural work.
Simple crack repairs take 1 day. Pier underpinning (8–12 piers) takes 2–5 days. Wall stabilization takes 1–3 days. Major repairs can take 1–4 weeks. Most repairs are less disruptive than homeowners expect. You can typically stay in your home during work.
