"Jose was prompt and efficient and did a lovely job. I needed the moldy, very old, hanging insulation removed and taken away. I have already told my neighbors about Jose. When he finished and left, downstairs was spotlessly clean. I highly recommend him. NOTE: I could not accurately list the work Jose did, so I put in foundation because I needed something. This website is flawed,because you can not list what you had done, except in the narrative, and I want people to know what an excellent job Jose did."
