I'm in the process of getting estimates for replacing 9 windows and 2 sliding glass doors from local window installers and a couple of them use windows made by West Window Corporation. I can't find much information about them online except for the company website. They are a small company that's been in business since 1949 and service a small area that covers Delaware, Maryland, Virginia, North and South Carolina and parts of Georgia, Tennessee and West Virginia. I've got estimates for Simonton 5500 windows and their Inovo sliding glass doors and PGT EnergyVue windows and sliding glass doors but the estimates using the West Windows Allwed III (suppose to be their top of the line window) are serval thousand dollars cheaper. If anyone has information on these windows or has had them installed, I would greatly appreciate your help. Thank you.
