I first called Rem A D when I wanted to change out some really ugly nasty glass (circa 1971) in a bathroom. I had already had a very unpleasant and expensive experience with another glass company and saw a coupon for Rem AD and decided to give them a try. They were great over the phone going over the different styles of safety glass I could choose from that were tempered and not a fortune. They were on time, reasonably priced and they cleaned up after themselves. ( the previous company I used had managed to leave a trail of broken glass across my property) I have since had them out several times to replace all of my screens and to fix a sliding glass door.
