    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: ***************************************************

    We apologize for the delay. The check will be mailed 7/23/2024.

    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.

    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.

    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.

    if I could put a negative stars I would. we had our dream home built this last year. well unfortunately our contractor used cascade windows. now mind you we have numerous large windows and many other normal size windows. so not a cheap buy mind you. so almost every single one of our standard open and shut windows have an issue. either to loose and slide right back down, wiggle, or just wont stay up. then we have multiple other windows that are so hard to open that its a really big struggle to do so. they were supposed to come and replace springs etc. they came down from ******** ( we live in southern ******) three times mind you never let us know until the day of( we also live 45 minutes from town) and not once had the right supplies to fix or enough. and in between them coming down they would schedule days and times with us and just be a no show. ( we both as in my husband and I had arranged to take those times off work to be at the house. now almost a year later they have still NEVER fixed them. they just shipped the springs etc to us and NOW expect us to replace and fix them. we spent 10s of thousands on these windows and the a** hats are not fixing them. oh and they do NOT return your phone calls either. imagine that. I am so upset how irresponsible this business is.

    Purchased a sliding glass patio door and large living room window in 2008. The product was purchased thru a local window and door broker. We selected a local manufacturer ( LDL WINDOWS) due to quality product and good customer service with a "lifetime warranty. The slide track on the bottom of the door has broken and the latch has stopped functioning in the recent past. I reviewed the " lifetime warranty" document and started to work on contacting the manufacturer. Apparently shortly after this original purchase Cascade Windows ( Cornerstone) purchased LDL Windows, sometime in 2009. After some discouraging attempts, I finally got a hold of a very nice gentleman with Cornerstones warranty ***** I told him the complete story and he instructed me on the warranty process but said once submitted they would contact me within a week and we should be able to have our door repaired or replaced within a few weeks. I was so encouraged....Well three weeks after submission I contacted Cornerstone. The lady told me she sees my claim in the system and promised to expedite the next steps. Again I was encouraged....Within about another week, I received an email that told me When Cornerstone purchased LDL in 2009 they did not purchase the warranty portion of the company and since I bought the door before the company purchase was completed Cornerstone would NOT warranty the claim.I was totally shocked to receive this reply. To pour salt in the wound in 2014, we purchased eleven additional windows from the same company to complete window replacement to our 1960's era house. These other windows have an almost identical warranty to the door but due to me buying the sliding glass door a few months too soon Cascade (Cornerstone) won't honor the warranty and didn't even offer to repair or replace for a fee. I'm totally amazed at what appeared to be a respectable company would due to a customer due to a "technicality" and not honor a warranty.Thank you Money paid is approximate

    Business response

    05/13/2024

    Upon thorough investigation, the situation regarding the claim is rather complex due to the nature of our acquisition of assets from LDL, the previous company associated with the product. While we acquired certain assets from LDL, we did not acquire the entirety of the company, which impacts our ability to fulfill warranty obligations for their products.
    Unfortunately, this means that we do not possess the necessary parts to address your specific needs.
    In such cases where we are unable to provide the required parts, we typically recommend exploring alternative options with window and door hardware companies such as Swisco.com or Strybuc.com. They may have compatible replacement parts that could resolve your issue. However, we are still actively working on your case and we are exploring potential avenues for resolution and will continue to keep you updated on any developments.

    I am rejecting this response because:

    Very disappointed that I had to make a complaint thru the BBB to get any responce other than, were sorry but we can not honor the warranty due to our purchase of LDL  windows where we did not purchase the part of the company which included warranties. 

    Unless a customer complains apparently they just hope you would go away. Not what I would expect from a reputable company. Door still broken and I'm stuck purchasing another one from a company who has a long track record of honoring there warranties and top notch customer service. Back to the age old adage of you get what you pay for....  I am very disappointed in Cornerstones/ LDL products and customer service 

    Sincerely,

    ***********************

    Business response

    05/17/2024

    We have been in communication with the homeowner regarding the rejection of our prior reply. These are not parts that we offer since we only bought the equipment from the company and not the window/door line.
    If the homeowner purchased parts for the door, we will gladly reimburse as a one time accommodation but we cannot send parts because its not a door we manufacture.

    Complaint: 21666476

    I am rejecting this response because:

    We have not ordered "parts" for our damaged sliding door. The door in it's current condition compromises the security of our home. The door needs to be replaced ! I will be hiring someone to install a new door and be purchasing a door from a reliable company with a true " lifetime warranty" Cascade will not be on my list of reliable companies.

    Very disappointed that it's taken over 2 months to even have Cascade make this "one time" token offer. They have fairly local location of installers etc. that could have at least looked at our issues and suggested appropriate solutions, I have seen Cascade trucks in my small town since this issue has surfaced so I'm confident they could have made a truely sincere effort instead of this token effort only because I contacted the BBB.

    I would have considered a Cascade replacement door but was never offered an opportunity nor was it ever suggested. Might have matched existing windows better than other brands. Real customer service isn't difficult but is truely hard to find in the world today. Hopefully Cascade will make changes for future customers.

    Sincerely,
