If you are looking for perfect (I'm not kidding!) and creative work, as well as superior service use VAST Interiors, Concord Ontario. They designed and installed clear mirrors on our Foyer Ceiling around a skylight and created an air return using water-jet slots for the existing vent. I called several other mirror/glass companies and none of them could figure out how to do the work according to my designer's recommendations. Everyone was courteous, efficient and a pleasure to work with.
