We had our entire main floor windows replaced last summer, minus transom windows. We went with double-pane Restorations, made by Sunrise Windows. I think they’re based in Wisconsin? I’d never heard of them, but Hometown Restyling in CR did the work, and they spoke praises about them. We’ve had amazing experiences with Hometown on past projects, so we pulled the trigger. They’re very impressive. The efficiency of them is obviously excellent, but what really surprised me was how much quieter really good windows made the house. The entire project cost just under 16k.
