I would give this company a zero star if I could. The customer service is non existent and they do not stand by their product. Long story short my front window only 5 yrs old got condensation inside and cracked. I found out from the home builder it was a Ply Gem and it should be under warranty. I contracted Ply Gem and they were rude from the beginning. The receptionist was rude and the service man that came out pretty much called me a liar and said the home builder should not have told me it was warrantied. I had another company replace my window as Ply-Gem stated it wasn't a warranty issue so I went with another company who has stellar customer service. Once they started to remove the window he was telling his apprentice everything that was wrong with the window and the worst which caused the broken seal, which caused moisture, which caused it to crack, was that the window was shimmed on all four sides which is incorrect as it needs room to move. This was brought up to Doug at Lethbridge Ply-Gem who then accused the installers and said they only provide product. Then through investigation of my home builder it came out Ply-Gem provided a fully sealed unit and this was their warranty issue. Doug D from Lethbridge phoned me and apologized and said we would have to figure out payment as I already had it replaced and he was thinking a gift certificate as they cant do cash. I said perfect a prepaid visa would work. He said he would get back to me but never did. After a few weeks of ghosting me Doug refers me to his Calgary office as it is out of his hands. How? I have been sent now to three separate people at the Calgary office and only have gotten voice mails with no return calls. Now it has been a couple weeks and I am beginning the paperwork for small claims court. Do NOT PURCHASE from this company, you will regret it.
