There are a number of contractors on island. We suggest you meet with 2 or 3 to get estimates, details about their services, prices etc. It is always good to compare and decide from there. We like EDK , and Claritza (owns Maritza’s Car Rental), Barry Miller, and Cheo Molina. A whole lot of the process depends on what you want done, what services you want, and the price you are willing to pay . . .
