Rob just put in all new windows and patio slider for me. We like our house cool so keep it at about 68 all the time. Just in one day I can feel the difference. I can put the thermostat at 71 now and feel how the old 68 felt! They are gorgeous and I can flip them down and clean them. I’m so very happy with Compass Windows and Doors! Don’t mess with the big name companies that rip you off. Get an estimate from Compass Windows and Doors and pay much less for a better product!
