“The Window Source of Tulsa was recommended to us. We received bids from three window replacement companies. Window source had the best product at the best price. The installation was on time and professional. We were kept informed through out the process. We are very pleased with the final product. About two weeks after the windows were installed I broke the outside pane of one window while mowing the yard. I contacted Window Source and told them what had happened, offering to pay for the replacement. They replaced the window free of charge. They are a pleasure to do business with.”
