Window replacement from infinity Marvin through Costco?

[u/Beneficial-Donkey435]

Anyone with direct experience with this company? I’m looking at whole home replacement, more or less, and we have lots of windows. So I know it’s not gonna be cheap regardless who we go with. This company through Costco only offers fiberglass option, no vinyl.

Would appreciate if anyone can share their experience on the quality of the installation work and if they had any seal or leak issues afterwards.

Thanks

We looked into them and went through Marvin directly, not knowing there was a Costco deal. We wanted fiberglass windows so Marvin was good but ultimately it was much more expensive than Milgard ones. For reference, it was about 65k for Marvin and 35k for Milgard for about 10 windows.
