windowscanada.com 5 Sheriann @2015-11-03 I purchased windows for my whole house through this company and I have and would continue to recommend this company. I unfortunately was the recipient of some windows that had argon gas leakage which streaked the windows. The windows are over 10 years old and this company has replaced each and every one of them. The warranty provided by this company has been remarkable. I call and they service.
