I purchased about 20 of the Certainteed windows in 1992. The cover of the warranty stated very clear (LIFETIME WARRANTY, LIMITED NON-PRORATED) In 1992, the Certainteed windows were made by Viwinco in PA. In Certainteeds warranty it also states, they only warranty the vinyl lineals and not any part not made by them. They also state that they licensed other companies to manufacture parts of the window but they did not mention what parts or who made them or what their warranty was. I bought windows from Certainteed and not 20 other companies. They came put together as one window, not in pieces. If this is what Certainteed considers a lifetime warranty, than I would never buy another Certainteed product. Now after reading about all three of there reviews, I would make sure if I buy windows from any company, that there are not made by Certainteed, Viwinco or MI Windows.
One of Certainteeds largest distributor is THE ROOF CENTER. So before you buy a window from any company, make sure it's not one made by Certainteed, Viwinco or now MI Windows
The complaint has been investigated and resolved to the customer’s satisfaction.
I am having the same issue with the window seals what can be done
I purchased 8 Certain Teed windows about ten years ago. Everyone is coming a part. I thought these were top grade windows. Tried reaching out to the company. No success.
The contracter installed 12 doublehung window in 2005. On the dining room window the seal didn't hold and there is rust between the two panes so bad that I cannot see out of the window. There is a lifetime warranty on them. I chatted online and was told that I was being referred to an expert for $1.00. I chose to pay the $1.00 by PayPal, however, I was not sent to "an expert for the problem" but to another screen wanting $56.00 to join Certainteed. I clicked off that screen, but was not directed to the "expert" that I was told would help me resolve the problem. I know there was a recall on the windows due to failing seals. What company charges customers to register a complaint not only for $1.00, but for another $56.00? Still have an visibly obstructed window and no answer. Also hve 2 windows that the bottom and top sashes have to be propped up to open or close! This company is a TOTAL RIPOFF and their method of registering a complaint is a TOTAL SCAM!
same issue as stated PATHETIC WAY TO DO BUSINESS !
