Many Seattle homeowners make the mistake of hiring the first mold contractor they find without checking credentials. Washington State requires mold remediation contractors to hold a contractor registration with the Department of Labor and Industries, and you can verify this at lni.wa.gov. It's worth the five minutes - unlicensed work can create bigger problems down the road. PuroClean Northwest is a mold remediation contractor serving Seattle, and they're worth considering if you've discovered mold in your home.
Seattle's wet climate makes mold a real concern, especially in older homes like many of ours built around 1968. If you're getting quotes, expect a typical remediation project to run somewhere between $1,800 and $5,000. Before you commit to PuroClean Northwest or any contractor, ask them directly about their licensing status and request to see proof of their current registration.
