When I bought the house I knew the original windows would be replaced one day. I decided the tenants deserved to have windows that I would want myself so I arranged to have them all replaced. I used a local recommended window replacement company and was pleased with the result. "That Window Guy" in Lindale, Texas was awesome.
They recommended these and we wound up replacing 8 windows in the home with white vinyl, single hung (one of the 8 was a non operating small picture window) premium replacement windows. The glass will be double pane, insulated with a lowE coating and argon gas between the panes.
I couldn't be happier with my choice!
