Most companies in the fenestration industry have a lifetime warranty. Very few actually provide the service described. Avoid labour costs. Enjoy prompt, polite and punctual service. Window-Pro is owned and operated by Canadians whom customers, dealers, and installers trust to provide service, and parts when required and according to priority. There is no need to shout for service, ask and we shall be happy to fix what is broken. We get more referrals from services than installations!
