Window
Ordered windows for new house early July 2021
Windows delivered mid September and placed directly into my sea can
Window in question installed October 22 / 2022
Noticed chip in glass on the inside right hand side
Contacted Gentek in regards to this and a couple of windows that would not open correctly
Received email advising me that I would be contacted in regards to repairing the window opening problems but they would not warranty the glass
I paid $1090 + tax for that one window and I did not break the glass and they are refusing to fix it.
Desired outcome: I would like the glass replaced
Regency, Vinyl Window, Double Hung, 1 Lite, 29 1/4"x67 1/2". Sashes split evenly. Colour White, Energy Plus ( Standard )
We purchased a number of new Regency Windows from Grant Home Hardware in New Liskeard, Ontario and installed professionally in 2019. The windows are ok except for one pane that is fogged up and has condensation between the two panes of glass. It was noticed within a few months of installation and has become worse as time passes to the point that the window pane is unsightly and probably has lost it's insulating properties.
Included is a picture of the purchase receipt. I've also included two pictures of the window, the upper pane is the leaker.
So, I need help.
Thank you,

Desired outcome: Can you replace the window, or at least the leaky pane and have it installed at your cost?
BAD GENTEK Windows
Bad Gentek Windows!
We installed Gentek windows in the spring of 2011. One the glass was crack by itself last March. The temperature was -13 degree Celsius. I called M&M Windows Co. Inc. who installed the Gentek windows for us. The sales person explained that the temperature was too cold. Our house was an old house. The cold pressure made the wall change shape and pushed the window unevenly, eventually it cracked the window and the glass broke. Eh? Did it make any sense to you? The cost to replace the window was $500. Today, Temperature is -17 degree Celsius. 5 out of 21 windows has frosted (snow flakes) inside the glasses, yes, the frost are between the glasses. This is ridiculous.
Please advise if you have any suggestions.

Gentek window fog on outside
I just had 13 windows installed across the front of a new addition in June 2014. The windows are manufactured by Gentek, which may or may not be relevant. I did see other users mentioning similar problems and I am hoping for a solution or at least an explanation.
Like the other users, the condensation occurs on the OUTSIDE of my windows, even when the casements are wide open. In the attached picture, you can see our big picture window fogged up completely. It occurs each nite at about 5am and remains until the sun burns it off around 11am. The windows are wide open and there is plenty of air circulation between outside and inside. Not all of the new windows do this, but most do.
The intention of the windows is to be able to see an awesome view. Clearly, we are frustrated by the result.
The complaint has been investigated and resolved to the customer’s satisfaction.
Bad windows
About 4 years ago I purchased new gentek windows for my brand new home, durinng our first winter we noticed a considerable amount of frost build up on the outside of ouur windows we called the manufacturer and to no avail, we had to take them to court and after four years two independant engineers failing the quality of the windows plus an independant inspection of the installation and a report, and 41, 000 in damages, legal expenses, I thought I woould share my experience with the rest of the world and suggest to anyone out there thinking of purchasing any products from gentek building products not too I will post pictures and reports if intrested
The complaint has been investigated and resolved to the customer’s satisfaction.
Second time the Gentek Regency window cracked , the installer and the window guy from Lyon's where I purchased it , said , they do crack sometimes , but the odds of that happening twice was weird . Waiting to hear from Gentek , if warranty will be covered AGAIN !
I just had 15 Gentek windows installed and I am not impressed with the spring loaded screening system they have for the windows. It leaves an open gap at the bottom of the screen system which allows tiny insects like
no-see-ums (black flies that bite) to easily enter the house. Also, I had the windows painted in brown to match outside of the house. They were delivered all scratched. The touch up paint they give you is so thick it makes a mess when you try to touch it up. By the way, it was not the installer who scratched the paint. I personally watched them remove the wrapping around the windows and the scratches were there. As for other issues with the windows, it is too early to tell. I will let you know after a winter has passed.
I had no condensation problems with the windows. All is good but the screens are still an issue (spring loaded) I had them replace the screens but there is still a problem with a gap. I had to use painters tape to seal the bottom of the window to keep the bugs out. Imagine paying $20K for windows and you have to tape the bottom because the screens don't fit properly!
I received a quote from a local window and door business which I considered much too high so I did my homework and found other Gentek Dealers.
Windsor Plywood informed me Gentec will not give them a quote for me because I had a previous quote from my local dealer. This is terrible business practice. A homeowner should have the right to shop around for the best prices anywhere possible. I will be investigating and will be in touch with the Better Business Bureau.
They have a price book and can give you a price .They are a customer of Windsor plywood and don't want to take their business. Buying windows from a lumber company is very expensive .Use the gentek regency line or the 400 regency .
14 Windows installed in March of 2014. ICE, not condensate or frost INSIDE of my house. SEE Photo. I also was told TOO much humidity, room temperature is too cool. I sleep in this room ! I don't like to sweat at night, not to mention, the INSIDE of the window is LESS THAN 32 Deg F !
Gentek are 'builder windows' prone to condensation and frost build-up. This is not just aesthetics, this means the window is not performing/insulating. Start with purchasing a Higher Quality window to reduce the chances. Then choose TRIPLE-glaze windows (Not in Georgia, of course) to reduce it further. Up the quality scale again is Krypton Gas and Offset Technology - which all but eliminates this problem except in extreme environmental conditions. Great windows need a great installation. Just make an effort to find out WHY your windows are priced to slow BEFORE you buy them. It doesn't do you much good Afterwards. BTW, I'm completely biased ... as I happen to sell the great ones.
Do more research before you consider to install GENTEK windows!

I have just installed Gentek windows and I am having a similar condensation problem. The condensation is on the outside of the windows and windows, including the problem ones, pare wide open. There is no a/c nor heat and air temp difference between outside and in is zero as the windows are wide open. They fog up at about 5 am and clear around 11am when the sun burns it off.
Would Rainex or a similar product help?
I am not sure it is a fault with the window, but it is a phenomenon I have not seen until these new windows.
Does anyone know if triple glazing windows are better than double glazed ones for the Ottawa Ontario region? And would they cause frost build up? If so, what should I do to remedy the problem? Thanks for any advice.
We are experiencing same thing -cold and frost on our windows. Gentek sent over a sub contractor and gave us the same excuse that other poster experienced. Would you please share your file with us and advise how you went about suing this company. We are tired of the run around that we are angry.
Thank you
I have been a builder for many years i have installed pella dashwood pollard & pella vynl replacements with no problems. However these Gentek vynl double hung leak air where they join lots of air you might as well have window part way open
We got 2 replacement windows (gentec) double hung, and the air leakage is the same or worse than the old ones! They came and put more weather stripping on the one but it really makes no difference. I am so disappointed that I am going to have to go back to putting plastic film over my windows! What a waste of money!
That’s right, I have a video of the window shut and locked and a Kleenex blowing out level at the top of the window where they meet . This was at -17 degree weather ! I don’t know what to do about it. I have complained several times and the installer comes out, adjusts them, but no difference! I now have plastic over my newest windows. Wish I had kept the old ones!
