We'd love to help - please let us know of any questions you have as you're researching your window options.

No matter the series, Marvin is a much better choice. The quality is superb in comparison to anything Pella. I would list the negatives on Pella but don't have an hour at the moment.

Unfortunately I had a very bad experience with Marvin. I ordered 19 windows (costing over $19,500). I went through their website to one of their authorized dealers, J.F. Johnson Lumber lcoated in both Millersville and Edgewater, MD. J.F. Johnson Lumber told me they had been trained by Marvin on how to measure their replacement windows and that they were Marvin "experts". They proceeded to measure every window wrong and then tried to blame it on my contractor, who did not measure the windows. Marvin offered to RESELL me the windows at their cost. I said no thanks since I had already bought the windows, used a dealer recommended and trained by them who then proceeded to totally screwed up the measurements. J.F. Johnson Lumber was the worst company I have ever done business with. Fortunately I knew my contractor had not measured the windows or his reputation could have been seriously damaged. I wish I would have gone with Anderson windows.

Adrian Fish, we're incredibly sorry to hear about your experience. We'd greatly appreciate the opportunity to discuss your purchase if you'd be willing to message us here with your preferred contact information. Thanks very much.

Marvin did reach out to me again and still offered to RESELL ME WINDOWS I ALREADY BOUGHT THAT WERE MEASURED WRONG BY THEIR AUTHORIZED DEALER! WOW, I am so not impressed. Go with Anderson. My architect uses them and has been very happy.
