Wallside windows are junk!!!
The home we purchased back in 2000 had Wallside replacement windows.Several of them have condensate between the panes.
It is very difficult to close them and lock them. I believe this is the result of both poor craftsmanship and substandard installation. There are gaps in most of the seams. While trying to close and lock one this morning the bottom horizontal piece separated from the window.
And because nothing lines up properly it will be very difficult to repair. There is nothing about these windows that is well done.
I don't know what the original homeowner paid.But I assure you they were ripped off.
