I hired Gem windows to do the windows on a large renovation job and in terms of quality of customer service and installation quality and delivery you could do no worse. A November 2016 installation date is still not completely finished and they have billed me in full without my consent. There have been so many problems it would take me hours to list them all here but below are a few of the main issues:
1) Upon initial delivery they did not bring nor had they ordered one door from the original contract and I had to prove to them it was in the original contract (which it was). This door then took many months to arrive.
2) One fixed window was installed upside down and another with the drainage on the side as it was manufactured wrong. This caused the windows to gain a tremendous amount of water which delayed the interior finishing of my house for many many months as we tried to determine the source of the water. In contacting and inquiring with Gem I had to call them many times and send the same information multiple times before they finally investigated the windows and identified them as the problem. To their credit, eventually, they did fix the problem.
3) Most large windows are bowing across the length as their installers only shimmed on the sides and spray foamed the tops which the pressure bowed the windows significantly. See attached photo. This has not been addressed. The owner was supposed to come to my house to look at this last week but did not come and instead chose to run my final payment on the CC I had used for earlier payments without my consent.
Like I said, this is only a partial list of the problems I have experienced. Suffice to say, this is a terrible company to deal with and I hope by sharing my experience it will save someone else from such a fiasco and so many 'firsts' one should not encounter.
