05 Before you hire

What to ask before hiring

  1. Can I see your license and insurance?Look the license up on the state’s own portal. It takes two minutes.
  2. Who pulls the permit, and is it in the price?It should be the business, and it should be in writing.
  3. What is the payment schedule?Payments should follow the work. Be wary of large deposits up front.
  4. Which parts of the job do you subcontract?Most do some. You want to know who will be at your home.
  5. What does the warranty cover, and for how long?Labour, materials and equipment often have different terms.
  6. Can I talk to two customers from the last year?Recent ones, not the showcase project from years ago.
