“Professional organization, a pleasure working with Juan.”

"Not only was he extremely responsive – I got a call 10 minutes after I submitted my request on Angi even though it was after normal business hours – he came the next day, on time, to assess and discuss the possibilities of repairing my leaky roof! Giving me a two-day window of when they would be available to fix the problem and a price range depending on the scope of the issue which I very much appreciated. Thank you, Wilson for coming exactly when scheduled, sending me pictures of what it looked like up there, confirming the scope, and fixing my roof!"

"I will recommend him to all my friends and family."

"I feel fortunate that I found Juan from Angie’s list. He had to fix the mess that the previous contractor created to install a bathroom in my house. It wouldn’t have passed the inspection if Juan didn’t come to correct the errors. All his workers are all so courteous and hardworking. The price was very reasonable and the project was finished at the scheduled timing. I will recommend him to all my friends and family."

“These guys are fantastic! This is the second time I have used them and both experiences were excellent”

"Last year we had a major leak in a slanted part of our rubber roof. Fixed perfectly. No leaks again. This year we had other parts of our roof leaking (1870 house. Lots of roof pitches and types) they identified the issues, replaced two small roof areas on bays areas, replaced all the broken slate tiles and replaced very old and non-functional down spouts. Ramon and Wilson are kind, conscientious and very reasonable. Their services are highly recommended!!!!  I will be using them again for a project on our barn next. Great team."
