We recently had a good experience working with Triangle Glass. I reached out to David Beck at Triangle Glass over the phone, to place an order for a number of insulated panes for windows that needed to be replaced at 3 buildings. He responded within a day with a written quote. One other glass company I called took more than a week to come back with a quote, which was just about the same price, and another never responded to my two calls requesting a quote. David was in touch over email as we modified and eventually placed the order, and the delivery went very smoothly and on time to the three locations. We thought his quote for installation of the glass panes was high, so we contracted that work elsewhere. The five star review is for the smooth ordering process and good quality/acceptable price of the glass itself.
