I was very happy with the installation of my pela windows and liked the excellent service I receive from Mike Kotovitch

I'm very satisfied with the care and attention that Gem Windows paid in supplying and installing a new door at my son's home recently. You replaced the old wooden door with a new one, it's well finished and very draft proof. An excellent product, well installed, a very good job. Thank you! I will be recommending you.

In the past, we happily purchased basement windows from GEM WINDOWS. The whole process was stress-free and we are still 100% satisfied. On that note, we recently decided that it was time to shop for some new windows for our home. I immediately reached out to GEM...I would like to focus GREATLY on the EXCELLENT CARE AND PROFESSIONAL COMMITMENT/ DEDICATION that YANG provided us with.

The windows look beautiful... are very high quality, have the best workmanship, and the price is very reasonable. We are very lucky to have found the best company for our window replacement.

GEM provided first rate service in getting our broken door window replaced so quickly.... It is a pleasure dealing with Gem Windows and Doors who are honest and reliable.

Our front door lock failed and I called GEM... Within a few hours they had a replacement lock for me. I was impressed.

We were happy with the quote and Seymour's knowledge of windows and doors. The installation team of 3 was very efficient. We went from a white exterior to dark charcoal and I cannot tell you how it changed the look of the house (100% better). We switched it to the most amazing sliding door with a 3-locking system at the back. It was a great experience for us and I'm in love with my windows!

I was very impressed by the GEM crew. They were very courteous, tidy, hardworking, and efficient despite the cold temperatures and piles of snow. The windows look beautiful, and I can feel the improvements in heat retention already.

We recently had Gem Windows come and install windows at a house that we are renovating. The process started with Mike. I am so thankful Mike was part of the process. He was accommodating, kind, knowledgeable. He took the time to come out when it best fit our schedule. He gave his opinion that you could tell was based on his experience and he also listened to our opinions with respect. He explained the process and was a great help along the way. Mike wasn’t pushy— or aggressive in his sales approach. We weren’t sure if we were going to do the windows or not and he still happily and with kindness provided our quote, took the time to have us in the show room to look at windows. We are so happy with our windows and how smooth the process went with Gem and we are so Thankful to have met and worked with Mike!
