What can I say other than we absolutely love our new windows! Michael was responsive, helpful, accommodating, and competitively priced. This was my first adventure replacing windows as a homeowner and he patiently walked me through options and addressed every little question. His installation team was professional and showed great attention to detail. They installed 13 windows (some of them very large!) in a single day with limited disruption to our home and family.

Our new windows have completely transformed the look of our home and we're thrilled with the service and product. If you're looking for quality work and responsiveness at a competitive price point, call Michael!

After getting estimates from a number of companies, I decided to go with Michal at Custom Exchange Windows. He obviously knew what he was doing when he measured and gave his estimate. a great price too! My windows and sliding doors were original from 1975! The new windows and doors were replaced in one day by a team of 2 (sorry I don't remember their names, but they were efficient, professional and nice). I am loving my new windows. So fresh and clean and quiet! So glad I went with Custom Exchange Windows!

We just signed a contract to purchase Simonton DaylightMax windows from Michal and he has been outstanding. My wife and I had a million questions and Michal answered them all with a good attitude. We also got a lot of proposals and his quote was super competitive. We are excited to have the windows installed and so far have been extremely impressed with Custom Exchange and the entire process!

Michal and his team did an OUTSTANDING job on the installation of the windows. Michal was very easy to talk to and gave a very accurate estimate of when the windows would be ready for the install. On the day of the install, the crew was prompt and on time and went right to work. They were very thorough, respectful of the property and did and excellent job of installation, caulking, and of cleanup. The only thing that they left behind were sparkling clean new windows, BRAVO! I highly recommend Custom Exchange Windows.
