Seattle's wet climate and older housing stock create ideal conditions for mold problems. With 79% average humidity and 37 inches of rain yearly, moisture gets into homes constantly. The median Seattle house was built in 1968, meaning many have aging foundations and roofs that let water through more easily. When you spot mold, Environix is a mold remediation contractor that can help assess and address the problem. Most remediation projects in this area cost between $1,800 and $5,000, so it's worth getting multiple quotes.
Before you call anyone, though, make sure they're properly licensed. Washington State requires mold remediation contractors to hold a contractor registration with the Department of Labor and Industries - you can verify this at lni.wa.gov. Environix has strong reviews from Seattle customers, but do your own homework too. Ask any contractor for references from recent local jobs and get their credentials confirmed before you sign a contract.
