Windows in Southeast Michigan

I have gotten three quotes for replacement windows

The quotes are for

Polar Seal which are manufactured in Grand Rapids MI

North Star which are manufactured in Canada

Silverline - Which is part of Anderson

I have read reviews on the Silverline brand, but don't really know anything about the quality of the Polar Seal or North Star Brands

Does anyone have any insight on these two brands? Any help would be much appreciated

I'm also in southeast Michigan (can you guess where) and had a Polar Seal rep out. He looked around, took some measurements and then dropped off an estimate a couple days later, but didn't have an actual window with him. Hmmm. Think I will keep looking. I have a LOT of windows that need replaced. Let me know if you find anything that looks good.

I tried to get a Marvin estimate, but the guy (caddilac windows) came out and I never heard from him again. Even called a couple of times. That tells me all I need to know about them. I have a Marvin guy from another dealer coming out soon.

I did have a Schuco rep out. Nice product but really expensive. Still in the running.
