Tracy Bowen
A couple months ago, took an old window frame in just needed one small repair. The lady that was supposed to be working on it. claimed she had bigger projects. So we were shoved in the back pretty much when I asked her, how much longer it was going to be? She said, maybe a month or two that is way too long.for A small piece that needed to be repaired. So at this point we would have been looking at 4 months just for 1 repair you all should hire more people that specialize in that department.If she is so backed up

Koonse Glass came out to see why my sliding patio door was catching. They showed up on time. The guy did a great job investigating everything thoroughly, and made sure to explain everything to me. I would definitely use them again.
Anne Heine
Michael & Justin were so kind to come fix my glass shower doors and measure my window for replacement. They were very kind, professional, friendly and helpful. I highly recommend Koonze glass for their excellent product, customer service, support and care.
Melanie Gramke
We are so pleased with our new windows and appreciate the speed of service and the time that was put into making sure it was right. We had a complicated window replacement with a lot of labor time that was very involved- everyone was very helpful and honest through the entire process. The crew came in even through the holiday season to replace our windows and we’re very transparent about pricing and communicative about scheduling. I would choose local like this over big box companies any day.
