What should you check before hiring?

What to ask before you hire

  1. Ask whether it has been renewed. Something on this license ends within 60 days. Check again before you pay a deposit.
  2. Get the license number in writing. The name on the license should match the name on your contract and invoice.
  3. Check the class covers the job. A license for one trade doesn't cover another. Washington license classes
  4. Ask for a certificate of insurance sent to you by the insurance agent, not handed over by the contractor. How to read a COI
  5. Ask who will be on site. If a crew works on your property, ask for proof of workers' comp. The L&I file doesn't record workers' comp, so ask for the certificate.
  6. Put it in a written contract: license number, price, start date and payment schedule. Check the license again on the day you sign.

If the license is lapsed

  1. Don't sign or pay a deposit until the L&I shows the license active again.
  2. Ask the contractor why. For a bond or insurance lapse, ask for proof that the new bond or policy was filed with the L&I, then check again.
  3. If work has started, hold further payments, keep the contract, receipts and photos, and file a complaint with Department of Labor and Industries (L&I).
  4. Check another contractor. Washington license lookup
