I have been living in my house for over 3 years now and was very displeased with the windows I had, they were the ones that slide up and down on a track, the ones in my bedroom were the worst, one window had no screeen but would open properly, the other had a screen but needed a piece of woood to hold it up. All in all bad windows. The windows always felt cold in the winter. I got 2 other quotes before settling on GEM, Seymour was very proffesional, Walter was great. He came and took the exact measurements and the windows were ready almost to the day he said they would be. The installation went very smoothly, I have seen panes of glass replaced but never the whole frame before. I learned something too. Thanks to all.

Good value for the price. Efficient installation.The product quality is good and should provide better heating costs as well as a substantial improvement in aesthetics helping at the time of resale.

Gem Windows, Jim Christopoulos, Production Manager was excellent. Even though the door latch was out of warranty he replaced the part for free and when problems arose with the reinstallation ... he made a house call. That's customner service you see everyday!

We first started using GEM about 17 years ago when we had to replace the screen door at the side of our house. We have an old house, almost 100 years old, and nothing is standard sized. I called around to various places and the only company that was helpful and happy to provide and install a custom-sized screen door was GEM. We have since replaced almost all our windows (over the years, a few at a time) with GEM, including a back patio door that was oversized, not standard. We recently used GEM again to replace our front door as well as our front hallway windows, and 2 other windows in bedrooms. The GEM salesperson listened to what we wanted, made some suggestions that fit our budget but would still give us the effect we wanted, and everything followed from there. The installers are very neat and clean up thoroughly after themselves which we (and our neighbours) appreciated. The door and windows look amazing.

I purchased a beautiful door and hardware from Gem almost 3 years ago. I recently called them with an issue and they came out the next day. Gem's customer service doesn't end the minute the sale is complete. With quality and service like that, I would definitely recommend Gem to my friends and family.

Length of time from ordering was very long. I was told approx 6 weeks and it took 10 weeks. The instalation was fairly quick, only the one day for six windows, which I expected. The workers were somewhat tidy but seeing that there was some snow outside making the ground a little wet, they could have been more careful and laid out tarps on the floor instead of tracking water and salt into the entire house and over wood floors/stairs. Their cleanup was fairly good other than some minor debris.

We were very pleased with the entire service, from the representative coming to our home to go through the different styles of doors, with an accurate approximation of when the door would be installed. \the contractor who actually installed the door, was efficient, very clean and tidy.I WOULD HIGHLY RECOMMEND THEM. THANKS
