"We had several windows and doors replaced and I was really impressed with the new windows and doors as well as the professional installation by Perry and his crew. They made sure everything was square, clean, and caulked. Great job! I highly recommend Metropolitan High Performance Windows."

"I called Pablo on Monday and left a message. He called me right back. He was very friendly and said he could fit me in between a couple of other jobs on Wednesday. He called me on Wednesday when he said he would, told me he could get to my house in half an hour and was. He measured the windows, set up his work station right from his van, and had made them within a half an hour. Everything fit. He was so nice, personable, professional, helpful. And took my credit card! Great job!"

"Quality work and best price in area for services performed."

"I was very pleased with my interaction with Brothers. Chase was a very good and patient sales person. Brothers was the first company I had give me a quote for windows but I wanted to check with others before making my decision. Chase kept in touch without being annoying. After getting several quotes, I was still impressed with Brothers, so went with them. They were very professional, showed when they said they would and installed my windows  (7 of them!) in a very timely fashion. Amir and Eddie did an amazing job! Kudos to them! We ran into a small problem regarding egress but that was dealt with to my satisfaction by Brothers. Thanks to Michael and then Josh for taking care of that!
Very please with their service!

"Rigo was professional and timely from the beginning and throughout the process. He responded quickly with my request for an estimate. The price quoted was exactly what I was charged. He scheduled the appointment within the timeframe requested, and was extremely flexible when we requested that the date be changed. The work was completed as scheduled, and the quality exceeded my expectations. I fully intend to request his services the next time I need windows."

"I received a great quality job for Felipe’s repair of the termite damage above my bathroom window! What I appreciated about Felipe’s approach was he was willing to brainstorm a few options with me. 5 stars!"
