We had our whole house replaced with Champion Windows, 9 windows and 1 sliding glass door. In 2015 the sliding glass door fogged over and was almost I impossible to open and close. They ordered a replacement door which came in around January 2016. Understandably it couldn't be replaced over with nter, however in the spring and summer the company repeatly cancelled every appointment if weather that week was bad and their new paying customers had to have their installation finished. So for a customer who has paid and this will be a nocharge installation we are at the bottom of the barrel. It is now August and no replacement yet. I can only hope they can fitt us into their so called busy schedule before its winter again. Would not recommend this company since they have no loyalty to their customers.
