Crawl Space & Attic Insulation Services in Seattle, WA | Insulation Co

In Seattle, crawl space moisture damage often results from wet insulation and drywall issues, including ice dam water damage. At Insulation Co, we start with a free same-day estimate to assess the extent of moisture intrusion. We then remove any wet or damaged insulation, install a moisture or vapor barrier, and address drainage with sump pump installation or repair if needed. Our team also performs mold remediation to ensure the space is dry and healthy. Using materials like closed cell spray foam, we help prevent future moisture problems, which is especially important in neighborhoods like Capitol Hill or Ballard where older homes are common.

Our attic and crawl space clean outs involve removing old, contaminated, or rodent-damaged insulation and debris, including animal waste. We then clean the area thoroughly to improve indoor air quality. After cleanup, we can install new insulation using fiberglass batts, blown-in fiberglass or cellulose, or closed cell spray foam. We also handle mold remediation, rodent exclusion, and sump pump work. This service is ideal for homes in areas like Queen Anne or the University District, where attics and crawl spaces may have accumulated moisture or pest issues over time.
