Chose to work with Michal and Custom Exchange after working through multiple estimates. Other providers were way too focused on showmanship and salesmanship, which created a lot of distrust. From the first call, through the estimate/measuring and projection of time to complete, Michal was extremely genuine, transparent with pricing, forthcoming about delivery and installation. His team of two that came to install the windows were very friendly, extremely efficient (took only 2 days for 21 windows!). In the end, he came in with a very good price, efficient delivery and installation, and continued support after completion. So glad I chose to work with Michal, highly recommended over pretty much any other provider (and I looked at 8 different ones for various brands).
