seemed like nice people however were only interested in getting paid. 70% of the windows steamed up and 20% of the hardware supplied broke down. It was like a scene from a comedy show, they were actually going to cut brick to make a window fit luckily my wife noticed they were installing the window for bedroom # 1 in bedroom # 2 opening. She read the markings on the frame and pointed it out. When they got the correct window it fit. DeMarco windows taught me a very expensive lesson I will never forget I really hope nobody has to go through what I did and now living with worse windows than my old ones.
