Comfort Windows put in some replacement windows for me. I was overall pretty satisfied with the service. The finish work could maybe have been a little nicer, mostly the trim work. They did a good job, though. The price was steep, but I feel the quality is there. I've used them twice in two different houses, so I guess I'd say I would go back again. It was a major job that I gave them, almost 30 windows, and they're high end windows. The quality with Comfort Windows is good.
