Window World 4000 Reviews
The Window World 4000 series is the entry-level vinyl replacement window that is a relabeled AMI window. Typically, the 4000 series is a MI 1650 vinyl window, generally considered a builder grade window. Generally not a vinyl window I would recommend for homeowners looking to stay in their homes long term.
If consumers are considering Window World, I would recommend upgrading to the company's higher end model. Ironically, when you do, the price you might be looking at could buy you a pretty solid mid range vinyl window from a stronger brand. I would recommend Window World if the particular branch in your city or town has a long and solid reputation of installation and service.

Window World 4000 vs. Wincore 7700
I have quotes on the WW 4000 and the Wincore 7700. Which would you say is the better of the two windows?

Tracey, the Wincore 7700 is the better window by quite a lot here. If the prices are comparable, I'd go with the Wincore for sure.
