We've used this company in both of the two homes we've lived in. In the first one, which was a historic home in the downtown area, they replaced an old bay window that was past it's useful life with a lovely panel of two large double hung windows. They matched the interior trim to the rest of the house and did a beautiful job maintaining the style of the siding and existing trim. The quality of the windows was really top-notch in every respect; from thermal and solar gain numbers and 'feel' in the room to the hardware and fit/finish. In the home we currently live in, we called Windowspan first because of the quality job they did at our other home. They installed an Anderson twin set to match the windows throughout the rest of the home. Again, they procured and stained the trim to match the existing trim. It looks so nice and really it looks as though it was original construction. We could not be happier or give a more ringing endorsement of Windowspan and of James personally.
