Ask what kind of warranty the contractor offers many contractors once they are done with your job and paid you will never hear from them again. Thus the saying the warranty lasts until you can no longer see their tail lights as the drive off. We provide a 2 year warranty on all labor and material. The warranty ties back into all of the above suggestions. A non-licensed plumber who installs plumbing that leaks will not be covered by any insurance be it theirs or yours. A contractor who lives job to job won’t be able to afford to warranty problems. And if you can’t find your contractor any warranty that you were told you had is going to be hard to collect on. A kitchen or bathroom remodel is a big investment that should last and should bring happiness for years; but it all starts with selecting the right contractor.
