Infinity® is for the discerning homeowner, someone as passionate about their home as we are about replacement windows.

So don't pick just any window or door for your home, go with the best.  Fiberglass!  Our Infinity windows and doors are made from fiberglass and are suited for Colorado's weather.  We hear all the time about homeowners who have vinyl windows in their home and they are leaking and sagging in under 10 years.  So vinyl windows may be cheaper to start, but in the long run, you most likely will have to service and replace them again.  This costs you more so you might as well invest in a better window from the start.  This is why we don't sell 50 lines of windows.  We trust fiberglass in Colorado, plain and simple.  We have the track record to prove it too.  As one of the oldest fiberglass window dealers in the country, we have had the opportunity to see how durable fiberglass is in our climate.  We know the 10-year mark is crucial and the Infinity from Marvin windows have surpassed that with no issues.  Other products fail by 10 years.   We have seen it first hand and replaced them.  We won't name names but they are usually plastic or composite. 

Our physical showroom is located in Littleton CO, but we provide services to residents all over the area.
