01Common services include foundation repair (cracks, settling, bowing walls), basement waterproofing (interior drainage, exterior membranes, sump pump systems), crawl space encapsulation (vapor barriers, dehumidification), and French drain installation for yard and foundation water management. Warning signs that warrant a call include cracks wider than 1/8 inch, doors and windows that suddenly stick, persistent musty basement smells, water on the basement floor after rain, or efflorescence on basement walls.
02When hiring, look for structural engineers or contractors with foundation-specialty certifications, get an inspection (often $200–$500, sometimes free with a repair commitment), and insist on a written diagnosis explaining the root cause — not just the symptom. Many cheap "fixes" address surface issues while the underlying water or soil problem keeps damaging your foundation.
03Costs vary dramatically by severity. Minor crack repairs: $500–$1,500. Basement waterproofing (interior system): $3,000–$10,000. Crawl space encapsulation: $5,000–$15,000. Major foundation repair with piering: $10,000–$40,000+. Always get 2–3 quotes and check that the warranty is transferable (it protects your resale value).
