This company was pretty good when it began, when the owner was still making house calls and really cared about the customer. Customer relations at that time was not an issue.
I replaced almost all my windows through Window World. This included 2 very large picture windows and and 1 oversized window.
I discovered the picture windows were impossible to clean. I called in a professional window cleaner to do what we could not.
Turns out, this was a manufacturing defect and the 2 large picture windows needed to be replaced. That was over 3 years ago.
I am Still waiting for my paid in full windows, for over 3 years to be delivered!
Lesson to be learned.....
Pay a little more for a lot less stress!.
