Ann Arbor Windows & Doors - A Pure Energy Company

May 2024

Our windows were installed earlier this month and they did a great job. We got to ask a lot of questions along the way and inspected each window before the job was considered complete.

I was very pleased with the pure energy company that put my windows in. They were very nice, professional and could not have asked for a better crew. The job was quick and when they were down the clean up part was outstanding. I love my new windows ( huge picture windows ) and the price was fantastic. I will differently be using them again for additional window replacement.

When it comes to glass repair, or for those who don't know it, it's actually glass replacement, I've become a verified fan of Kosin's glass. This is a Michigan glass company that supplies, installs, and fixes glass, from commercial buildings, residential homes, single family condos, townhouses, apartment buildings, offices, churches and anyone who needs glass. They've completed an impressive number of major glass work for residents and businesses in Ann Arbor and around southeast Michigan. They're also known for their glass architecture and construction work, having built and worked on commercial glass structures around the U.S. I use them for all my auto glass needs and they've replaced glass in my windows and doors of my home. The glass installation work has been the best I've ever had the pleasure of witnessing, which is what you want when it's your windows and door. They build epic custom glass showers and install them perfectly. Definitely worth getting a quote from Kosin's Glass, they actually stand by their quoting and use superior glass. A throwback to the great days when companies had pride in their craftsmanship and quality of the products they sold, Kosin's Glass is a family business that uses employees only for their glass work from the quote to the installation work. You can trust them because they aren't using subcontractors who you'll never see again. You will be happy you called Kosin's Glass.
