Sunrise brand replacement windows, work performed by Architectural Glass owner Ryan and his…read moresidekick Ben. Excellent install service, professional and attentive. My wife was particularly impressed how clean they left the work area, inside and outside. We purchased our recent house a short while back, and decided to replace the original windows(11 in total) with the lifetime warranty windows made by Sunrise. This is our second large purchase from Sunrise windows, first for our house in Illinois and now in Columbia SC. Based out of Michigan, I believe sunrisewindows.com is one of the few companies with the V-groove options. This eliminates the Colonial style grids, the V-grooves are lines or patterns carved in the glass panel therefore you get amazing light and the view is not obstructed by the grid pattern. Plenty of frame color choices, in Illinois we had white on the outside and the inside frame matched the hardwood door. They were Double Hung, for the Columbia house we opted for the Casement windows. Either style includes an easy to remove screen, either style allows for easy window cleaning from the inside. For reference, the windows are S2100A with Argon, high efficiency. The S2100A windows I believe are applied with 12 layers of coating. Architectural Glass Co. Of Greer, South Carolina is not only a great family business passed down from father to son, but also an authorized Sunrise Replacement Windows dealer/installer listed on sunrisewindows.com. Worth mentioning, the previous windows had a worthless lifetime warranty with a large window manufacturer chain, the previous owner managed to have them send replacements for the bad windows but they sent the actual glass only and would have been a waste trying to install them, the plastic frame was so damaged from the sun they would have snapped. This is not the case with Sunrise windows, our Casement style windows have a code imprinted on them. If ever needed, all we have to do is to call Architectural Glass Co. with the code and Sunrise will send exact match to be swapped easily. If we sell the house, the new owners can also call the Sunrise directly, the lifetime warranty is still honored. Keep in mind, these are premium windows and cost relatively more, especially if you choose V-groove carved in the glass for patterns or other custom colors etc. However, it's definitely worth it for the looks, quality and piece of mind.
