"I had a leaking skylight in my bathroom for quite some time that I finally got around to replacing. Jose came to take a look, I received a quote that same day and a week later a replacement skylight was installed. He was prompt, on-time, and very knowledgable. His work was excellent, you could not even tell that a skylight had been replaced. I highly recommend him."

"They were able to replace the skylight in less than 2 weeks after the quote. They did a good job and make the finish on the inside look good. A few weeks later, there was a heavy rain and my new skylight is no longer leaking like my old one that was replaced."

"Excellent , Excellent, and Excellent  from the sales personnel Al Vestro, office , and work people  Jeff and helper.  Digiorgi    professionalism from start to finish! including clean up!!
The basement windows are super ,air tight, easy open!
Now my basement is protected from old window air leakage especially with the harsh New England winter weather we have been experiencing!"

"Prompt, courteous and professional best describes this company. I had a detailed proposal and contract for a skylight restoration within a few days of meeting with Samper. With over 30 years experience in roofing I would highly recommend this company for your roofing needs."

"The guys did an excellent job replacing my old damaged skylights with some nice new ones. I would highly recommend Marco and his guys, in fact I’m going to use them again for a driveway repair. These guys are pros."

"Perez-Diaz took off my old roof, gutters, and 4 skylights. All new was back on in just a couple days. William shows up when he says he will (or communicates as with rain days). He and his crew are respectful and courteous. He did have sheathing work no one knew was there until the old roof came off, but I was charged for re-sheathing as per contract and as far as I am concerned he was more than fair about it. Even some repair work we discussed with the estimate was done to a standard better than I thought we agreed to. I highly recommend him."

"Reasonable prices and quality work. Most importantly they are very reachable."
