Our house, built in the late 50s, was in dire need of windows to replace the single-pane, jalousie style windows that were extremely drafty and provided no sound shielding from the outside. We needed windows in 6 rooms, 9 sections of windows in all, including several very wide sections (10 feet wide). We received estimates from 3 contractors, Cal Comfort was right in the middle, and gave us two quotes, for a higher end model of window as well as a lower end. We went with the higher end Milgard windows that included lifetime warranty. Cal Comfort was very prompt in their first visit to give us the estimate, and gave us lots of information as to what might be a good idea for replacement. After choosing them for the work, they came out again to get more accurate measurements, then placed the order for the windows which were all custom sized. Windows arrived after only 3 weeks, and Cal Comfort spend 5 days installing. Very friendly workers, very professional, keeping the entire area clean each day and removing any debris at the end of the day. I had three minor concerns before the end of the project, all three concerns were addressed to my complete satisfaction. We are very happy with the windows, and will definitely consider Cal Comfort again in the future if the need arises.
