We bought an old Tudor that we're currently renovating. The owner's a bath is a full gut and I wanted to replace this 56" square block window with something more aesthetically pleasing. My GC sent me to a local window person who was very pushy on using Marvin windows. I'm not as familiar with the brand, but I heard him out. He just sent over a $6K quote to install a 56" square privacy window with a diamond grille. He said the diamond grille was part of why the cost is so high. I mean that's astronomical. All of the windows, except this block one are original wood casement windows. And while we're starting with this window, the plan is to replace all of them due to rot/broken thermal seals. I had my heart set on keeping the diamond grille patterns that currently exist on all of the windows.

Are Marvin windows worth this cost? I'd love to hear any recent opinions on the brand. I did a search and pulled up a lot of old discussions with not so great reviews. I plan to reach out to Anderson and Pella as well. Also attached a pic of the exterior for reference.
