"Wilmar was a pleasure to work with. We had them remove asbestos popcorn ceilings. His crew was very professional and Wilmar was a great communicator. He explained the process and answered all my questions very knowledgeably. The preparation process was thorough and they took great care to protect my floors, walls and carpet. I especially appreciated that they told me in advance that there would be some paint damage to upper walls from the tape to protect them so that wasn’t a surprise. Price was good and they finished in 3 days."
