"We found REA Pro through positive reviews online. Jaime Rea was one of several contractors we interviewed. He is very prompt, energetic, and an excellent communicator. After an initial phone call and site visit, Jaime provided the estimate within a couple of days. The project – which included renovating 5 decks, repairing siding, and painting the exterior of the house – was started on time and completed within Jaime’s time estimate. His crew was very professional and personable and a pleasure to work with. We were really impressed with the quality of the work and their attention to detail. We are very happy with the final result, and would hire Jaime and his crew again for other projects."
