Steve from Calgary

I would like to say that Karl Bergan is very good at products he sells to the customers he encounters. I started buying windows from karl in 1996 for my home in Glenbrook. I purchased front picture window at the front of my home, the seal was broken on the frame,Karl suggested to replace with there argon gas filled window to save energy. I can honestly say after the install, what a diffrence to the living room temp stayed at a more consistant temp. The picture window was insalled about 2007. I have replaced all windows accept one kitchen. Both insulated front and back doors. Supreme windows makes a quality product.
