GEM replaced my patio door two weeks ago. The installers were very experienced and fast, it took no more than two hours. They cleaned up before leaving and left no mess. Great job!

Very competitive prices. Employees know what they are talking about and doing. High-quality products and delivery were all as discussed. Gotta ask for Tas! She definitely delivers everything as promised

Gem replaced all my windows two years ago. They still look and operate like new. Love the high-quality product and price. As far as I remember, the installers were amazing. I have recommended them to family and friends many times in the past.

Tas at Gem provided us with exactly what we wanted. A beautiful set of windows to match the door that we purchased in October. The installers showed up right on time and proceeded to professionally install and clean up like they hadn't even been here.

I must say that I would definitely recommend Gem Windows and Doors to everyone. I found the process went well and the installation was done smoothly. My parents as well have used Gem Windows and Doors and were also very pleased with the services.
