I filed a warranty claim on a French Door locking mechanism that was installed in 2017 and still under warranty. The warranty was filed on 7/8/24. I was notified by the company that they can no longer warranty the part due to it no longer being manufactured and offered a settlement. I emailed the claims representative with additional questions regarding the settlement offer and how it would be handled and affect the remainder of my product warranties and have received no response to multiple voicemails and emails. Their customer service line is no help as they will only send messages asking for a callback which then never happens. The door in question is an exterior door that no longer locks properly due to the faulty locking mechanism and I have expressed that this causes a safety issue as my home is not secure and still no response.

I have windows that were installed in my house when it was built in 1996. One of them became extremely fogged between the panes of glass, making it very difficult to see through. A warranty claim was submitted with Cornerstone Building Brands via their website. It took between two and three months for my case to be "assigned" to someone so it could be handled. They eventually told me that I could use a contractor to obtain the measurements of the window so that I can send it to them. At the time, I had a contractor doing other work on my home so I had him take the window hole/size measurements. I submitted them to the contact at Cornerstone.The contact them asked me in two subsequent emails to submit the measurements, which I did again. Then, I was asked again by a different person, to which I again sent them. Then, in another later email, the person told me that they needed other figures about the windows such as the thickness of the glass. By this time, my contractor was gone to work on other projects. I told Cornerstone that my contractor would not be available again for another approx. 6-8 weeks to be able to get any more information.I then receive an email saying that "We hope that the issue has been resolved, but should you still need our assistance, please resubmit your request on our website".I first submitted my claim with them on 3/30/24, and they tell me to resubmit my request on 8/1/24. These correspondences have been going on with them for over 4 months with no resolution. Cornerstone took 2 months to "assign my case" to someone. Then asked for "measurements" but not exactly what they needed. Then switched me a different person asking the same thing. Then when my contractor is not longer available for a period of time, they tell me to "resubmit my claim". My first claim has gotten me nowhere in 4 months.They appear to be trying to make me go away. I would like them to tell me what they need to honor my warranty.Business Response

Our **************** team reached out to the homeowner on 8/2/2024 requesting glass details including glass sizes, glass thickness, glass details, and the shipping address for where the glass will be shipped. We are unable to ship the glass directly to the homeowner, so the contractor will need to provide a shipping address. Once we have this information, we will place the replacement glass order.Customer Answer

I am rejecting this response because:It is insulting. I have provided the glass size to them multiple times, which is what they asked for. They did not ask for other specific information until just recently, and I am working on getting that information. I have also provided the address of the contractor to ship it to, and now they ask for it again as if it was never provided. This response from the company is the same stall tactics that they have been using with me for months, and then they threatened to close my claim. This is why I had to go to the BBB.

In August of 2022 we had new windows from Ply Gem installed on our home. Shortly thereafter we discovered that one of the windows leaked air so badly it produced a loud high whistling noise when the wind picked up. We contacted the dealer who couldn't make it out until December. He determined that he needed to get the factory representative out to inspect it. The Ply Gem factory representative finally came out in February of 2023 and agreed that the window was mis-manufactured and would be replaced under warranty. The replacement window finally showed up without warning in August 2023- no word from the factory representative about installation which was covered in the sales agreement. After MANY emails to the company, getting in touch with the parent company and other west coast supervisors, we finally got a request in April 2024 for a contractor bid for installation, which we sent to ******************. He sent us back a contract for installation accepting the bid, which we e-signed and sent back to him. His response was that we would be receiving a check covering the contractors bid within 30 days. Despite several more emails to ***************** we have not received a check to cover the cost of installation we paid to the contractor for the work done. This man does not respond to any attempt to contact him to resolve this issue of non payment: ***************************************************Business Response

IN 2020 we are purchased a house. In January 2024 we noticed one of our windows (Ply Gem) became foggy, we submitted warranty required information and about two months later the window was sent to us, unfortunately the corner of the window was cracked but customer service representative was very professional and sent us a second one. Since the company don't cover installation, she even provides us with contractors who can do it for us .This was previous case with this company ( PG-*******-Q5K4N0 REF.:032730005621)BUT NOW I would like to talk about the case I am filing, complain (PG-2566297-Z4T3C4 REF:030430009183) REPRESANTATIVE NAME IS ***************************. Month after we received first the window we noticed another window became foggy. We are followed the same steps ,but how surprise we were to find out now we have to pay not only for installation but for shipment also.!!!!! When i asked her why, the answer was we did it before for courtesy to our customers and now we don't do it. So not only they selling a defective product but don't want to take responsibility for shipment, $40 it what she told me to pay. First question is : every time they sent us a window i have to pay and like in my first case before window was damaged and second was sent to us ,its mean i have to pay for damage windows sent to me too? Second: Its not warranty at all!! Warranty is when the company takes responsibility for a bad product, come to your home and replace it without a question asked. How this business still has a A+ rating is beyond my understanding .??!!! In the end of my complaint, I would like to receive a new window and have the company also install it and refund me the cost for the installation of my first window.Business Response

I am rejecting this response because:
They asked for info I sent to them and no more response from them. They also asked that I contact them via Facebook. That I will not do. I need to know if they are going to replace the window or should I bill them for someone else to do it

In February 2018 we purchased a 3 panel sliding glass door. Two of the glass panels are stationary. On or about January10, 2024 I contacted Eastern Architectural Systems (EAS) about 2 of the panels becoming foggy. I was instructed by ******* to provide pictures so she could get approval. I was provided with order no. VOT1LY to use for any follow-**** On January 29, 2024 I was contacted by ******* who said the replacement glass as well as frames had been approved and was covered under warranty. (They had had an issue with the gas between the frames at that time in 2018.) I was to contact a dealer for shipment and installation (installation I would pay for) and provide that information to her. I provided ******* Glass to her. Shipment would take about 4 weeks.This is a 2nd home (*******************************************) that the install would take place at so I was concerned with dates. When ever I would call back about a shipping date ******* always said she would return my call after lunch.Needless to say I have never received a call nor installation.On May 28 2024 I again called and was told someone would return my call. On May 30, 2024 I called again and asked for a manager. I was given the name ** and left him a message on his phone. He has never returned my call.There is a 20 year warranty on the glass and I want the replacement ************** shipped so I can have them installed. EAS has terrible customer service and not living up to there warranty.Business Response

We purchased these windows in December 2021 as a new build. They were installed 4/27/22 for our main house and 12/2/22 for the pool house. Windows are hard to operate and had defects. One window in the pool house was cracked and the company that we bought prime windows through is supposed to come out and replace the glass this Friday. Meanwhile the sliding glass doors do not slide easily and being elderly is very difficult to operate. My family has trouble as well. The single hung windows I cant open fully as they also dont slide easily. We paid extra for the black windows and had trouble with the finish. At this point I want to be able to operate my windows. I think that is a very reasonable request. We moved into the house October of last year and have found this year when putting screens up, as it was getting warm, that the sliders screen did not fit.Business Response
