I needed to replace a broken double-paned sliding glass door window. I quickly learned that I needed to replace both windows as a unit, not just the pane that was broken. After extensive phone shopping, I selected Garcia's Windows and a large local company to give me a bid. The large company came first and gave me what I thought was an expensive bid. Mark Garcia came quickly, was very knowledgeable about the manufacturer of the slider, the type of glass and what was necessary to repair the window. In fact, he took the time to tape up the window for me so that it would not collapse before the new unit could be installed - and this was before he had the job. When he came in $230 cheaper on the price, the job was his. It's now installed and looks great. Thanks Mark.
