Jon, Dimensions in Glass, came highly recommended to us by our trusted contractor to do the glass for our large new floor-to-ceiling master shower. I spoke with Jon on the phone and described our plan. He was very knowledgeable and made some valuable suggestions, but was not pushy. He gave me a ball-park estimate that turned out to be pretty accurate. The work was quality, on time and fairly priced. Hopefully, we will not have any problems, but my contractor says that Jon is reliable and will stand behind his work. My contractor has always steered us right.
