Purchased windows in 2014. Salesman was very slick. Quality of install was very questionable from start. Windows are drafty. The inside pane window cracked this winder because of cold. I tried calling the local branch #92 in Hamilton. However, the phone service is no longer in service. I tried emailing service using the email on their site: service@clerawindows.com 3 weeks ago but never received a reply. I tried calling the service department at head office last week but never got a reply. I tried calling again today. The windows are supposed to have a lifetime warranty but this company's strategy is if they can get in contact with us, we do not have to honour the warranty. That seems to be the strategy based on a number of other reviews on this site. I have provided my account # and contract number every time I have contacted the company.
