Andersen by far has the highest quality window out there and with their financing options made it affordable. The Whole process from start to finish was flawless and now we have beautiful energy efficient windows that will actually last. Our installers Todd Arthur and Tim were outstanding, very professional, did a great job with the windows and finishing wood work. They did a great job with clean up as well, you couldn't even tell they were here, except for the beautiful windows. We should have done this a long time ago

Door Installation

Unless you're a handy-man or handy-woman, installing doors can present a variety of challenges. First, the old frame must be, literally, ripped out. This can be a tricky task for older homes when standard sizes were not used as often. Next, the surfaces might need to be sanded or modified to fit the incoming frame. Leveling the frame against the floor and wall boards are extremely important as the fit must be absolutely snug in order to prevent any leakage in air. The goal is to create a perfect seal around the frame and have the door open and close smoothly. We have learned the entire process and have the hands on experience required for perfection.
