Terrible Fit and Finish: Like Something Out of an East German Housing Block…read more We bought 7 large sliding doors, plus 3 windows, from Marvin's Elevate collection (formerly Integrity) in June 2025 for our sunroom. Installation occurred several months later. The terrible fit and finish on all 7 sliding doors is unacceptable. There are huge gaps where the trim pieces meet due to the sliding doors being manufactured with stocks of two different thicknesses. This manufacturing process makes it impossible to create a frame with a clean, flush edge. I can't understand how a process that consistently produces a defective product was approved. It is not an installation issue. I've been trying to get this resolved since the job was completed by first contacting the installer, then the Marvin showroom in Boston and everyone involved. A Marvin rep inspected the product and he agreed that fit and finish is unacceptable. He re-measured the sliding doors and ordered replacement stock, only to receive the same defective product. I've shared my photos and spoke with multiple people at Marvin. I've left multiple messages with the inside care agent in charge of my case. She has not responded to my calls or email. At this point, I would never buy a Marvin product again.
