Steve answered me right away and the estimate was taken within days to repair my guest bathroom ruined by mold from a leaky roof. Within days, his two workers completed the work (two days) and i have to say they did an amazing job!! They were serious and focused. Steve was very easy to communicate with, very knowledgeable, and his price was fair. Definitely recommended!
