Before you hire

  1. Match the name and number to your contract. If the names differ, ask the contractor why.
  2. Check the requirements for your job. Ask the agency whether the contractor has the license or registration your job requires.
  3. Ask for insurance and permit details. Get a current insurance certificate and check permit requirements with your local office. We haven’t checked these for your job.
