Gem Windows and Doors

I had many, about eight, vinylbilt windows installed in my home around 2001 by Gem. I found their salesman and installers very good. Recently in 2013, we were having a few problems with the hardware/openers and had no difficulty with receiving instructions on how to replace ourselves from the production manager (saving us the $200 service charge) and the lifetime warranty hardware provided to us with no problems. They are very helpful and easy to talk to - no pressures. I would recommend this company.
