We selected Marvin windows for our retirement home and have had the rep come out several times and adjust the sliding doors. This adjustment does not hold on two of the seven sliding doors that were installed. There are only two elderly people living here so there is no abuse. The insulation strip at the bottom of the sliders are creeping out, even after repair I have one that continues to come out. We have a custom made window leaking. Even when the rep comes here, he admits there is a problem, but Marvin does nothing and makes no suggestions.

I too have been taken in by Marvin windows. But in this case, over 200 windows. 80% of the windows leak air and water at the bottom corners and along the sides. Its not the installation but the windows themselves. They are rated high but in the real world fail miserably. They are made poorly with little or no tolerance factor. Wide gaps along the sides, poor sealing capabilities along the bottom, I don't know how they passed the government standards indicated in their brochure unless payola was involved. These double hung units can't even stop a 20mph wind. Save yourself the money and buy something else. Their service dept. is useless and they really don't care about their product and how it is perceived to the general public. Save yourself the aggrivation, time, and overpriced cost.

Only 15 years after installation, 5 of my 8 Marvin windows need to be replaced because the frames, sills and even some sashes, have rotted. The only 3 that don't need replacement are located under a porch roof.

I purchased the windows with Marvin's now discontinued "Flexicron" finish. During shipping the Flexicron finish cracked at the seams. Marvin sent several representatives to check out the problem. They all agreed that there was a problem but no one ever came to fix the windows and thus Marvin did not stand behind its product.

Because of the Flexicron finish I never noticed that the frames were rotting until after my warranty had expired. Imagine my surprise when, during the process of power washing the house to prepare for painting, I watched the window frames disintegrate. The Marvin representative that I than contacted expressed his sadness over my misfortune and kindly offered to sell me some new frames.

A 150 year old house that still has most of its original windows and the Marvin windows didn't even last 15 years.

Don't be taken in by the glossy ads of beautiful windows in expensive houses. Those windows were indeed beautiful, but at Marvin, beauty is only skin deep.
