Get matched with top window pros in Key Biscayne, FL

"The windows look great. Half of the windows were installed in one day"

"I had screen panels on my lanai replaced and a dog door installed. It was very easy to schedule an appointment for Juancarlos to look at what I needed and give me a free estimate. He was courteous and honest, and did not try to sell me on additional work that did not need to be done, unlike a different company that gave an estimate. Window and Door Group was affordable and competitive with pricing against 2 other companies, but the main reason I chose them to do the work was their professionalism and attention to detail. When I scheduled the work to be done, they were prompt, friendly, and showed me exactly what they were doing. They did an excellent job and cleaned up after their work. I highly recommend this company - Anamaria is easy to contact and work with, and Juancarlos did superb work. Much appreciated!"

"ASP Windows and Doors did an outstanding job on a very extended project. Jonathan and his team stood by their word and their work. They were always very professional, honorable and punctual. I would highly recommend ASP Windows and Doors"

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"Guinn & Sons replaced all of our windows and doors with impact at my house. I am pretty picky so they took the time to explain the options and products to ensure I was happy. Very communicative from start to finish and we love how everything turned out. They kept everything clean during installation too. I’m a realtor in Miami and I refer all my clients to them, and everyone has been very happy! I highly recommend them."
