Something that is critical for your contractor to have is proof of a license as well as insurance. You want to make sure you’re hiring a licensed professional with a proven track record of getting the job done properly. Having a licensed professional working on your project likely also guarantees the fact that the contractor is insured. If the contractor were to have an accident while working on your project, their insurance should cover any of their potential medical bills. If something were to be damaged during the project or prove faulty after the project, their insurance should cover the repairs or replacements necessary. Proof of a license and insurance is not only for the contractor’s protection, but for yours as well.
