Windows were ok. But the service was horrible. We had bow windows made, the salesmen came multiple times in attempt to measure the opening but when delivery day came the windows did not fit. Felt pretty uncomfertable when they kept asking me to sign off on measurements that they measured, now I can see why with all the erorrs. Salesmen after looking at our drawings recomended us windows that ended up not fitting in the opening (bow windows), now that I need to ask for support they told me that they only distribute the windows and I need to find my framers that installed the windows to fix the problem. Got feedback from my envelope engineer, framers, architect, and they all felt the same way. In general, if you are building a simple home with simple characteristics, Westeck can probably provide satisfactory service, but if you are buliding a custom home with unique features, you might want to check out some of the competitors. Now I can see why you have holdbacks on most trades..unfortunately Westeck makes you pay full ammount prior to delivery, so if you end up with the wrong windows.... good luck to you!
