My home was broken into and a sliding glass door was used as the entry point. My insurance agent made several recommendations, and Gaithersburg Glass was one of them. I called them at 9:00am, explained my situation, and was asked to make measurements of the broken glass door. Fortunately, my door was a standard size and they had a replacement piece of glass in stock. At 11:30am, Bernie Kalt (sp?) arrived and got to work replacing the glass. He worked efficiently and by noon, a mere three hours after the initial phone call, the job was complete. To have the work done so fast was a bright spot in an otherwise unpleasant experience.
