“I had never heard of the Window Source before using them and I called them just for a “third estimate”. But during the estimate, they were so thorough and presented me with so many options. And they seemed to be the one of the three I picked for estimates that were focused on what I wanted, not which style they wanted to sell me. I couldn’t be more pleased. The windows actually look better than I expected, and the price was a fraction of what their competitors wanted.”
