I would recommend you hire a licensed contractor. If you are unsure of who to use ask friends or family in the area for a referral to one. It is important you outline with the contractor exactly what you expect of them, especially being so far away. If you know someone in the area ask them to check in on a regular basis. I have several clients I have overseen property renovations for. It is important not to just hear what is going on but to have someone viewing the progress.
Hi Wondering. You hire a great contractor to do the work for you. You sign a contract with the scope of the work described in detail so there won't be any surprises for either party. You make sure the contractor is licensed and insured. You can have someone 'babysit' the job just to make sure you have an extra set of eyes on the project.
