A few years ago, an octagonal glass table of mine was accidentally split open. I couldn't find anywhere to fix it or find another eight-sided glass piece until I stumbled across this store. They offer lifetime warranties to any of their pieces of works, and they do windows, doors, and any siding. You can even call them for a free estimate. I was very pleased with the new octagonal glass pane that I ordered. It was even better than the old one because the sharp edges were all rubbed smooth.
