Before You Call Knock Knock Inspections

1. Do you also do remediation? If so, who checks your work?
2. How many air samples will you take, and will you take an outdoor control sample?

Ask for the company’s contractor registration number and look it up with the Washington State Department of Labor and Industries. Also ask for proof of insurance and industry certification for the technicians.

They list no storefront. Ask where the business is based and whether the crew is their own.
