We completed a full crawl space repair to address moisture, drainage, and structural concerns. A sump pump system with a battery backup was installed to manage groundwater and prevent flooding, even during power outages. The entire space was encapsulated and sealed with drainage matting to protect against seepage and improve durability. We removed debris and old insulation and treated all surfaces for mold. A dehumidifier was installed to control humidity, and new moisture-resistant insulation was added to boost energy efficiency. Structurally, we stabilized floor joists with a steel jack system and replaced a 10-foot section of rotten sill plate and rim joist, supporting the area with a steel I-beam and new framing. We also redirected exterior water flow to a catch basin to keep the area dry. The result is a clean, dry, and stable space ready to protect the home for years.
