What does that mean, LICENSED, INSURED, AND BONDED?
This means that the contractor you select has passed tests given by the state of Arizona to be sure he is knowledgeable and also has the experience the state requires. It also means that he carries Insurance such as Workmens Compensation in the event that someone got injured on the job that can be treated for that injury, and the Bond protects you so you are satisfied with the completed job.
