United Better Homes replaced 20 windows (8 Marvin and 12 Mezzo) and a sliding door in our house. This included foam insulation, wrapping, and replacing some rotted wood at one window. The work went like clockwork. A large crew arrived on time and worked nonstop until the job was done. Everyone was professional, friendly, and responsive to questions I had. They also replaced some trim around the slider that I hadn’t thought to include in the work. On top of that, they primed and painted the entire door frame AND my kitchen window so that everything looks very fresh and clean. I truly am very impressed by their work and would highly recommend them. I plan to have them back when it is time to reside our house
