Light fixture installation in Toronto means working with ceilings that were built long before anyone thought about a heavy ceiling fan. I swap chandeliers, flush mounts, vanity lights and fans on circuits that already exist, from Victorian semis in Cabbagetown to condos on the waterfront.
I take the old fixture down carefully, check what the box is actually fastened to, and tell you straight if the mount needs changing before the new piece goes up. The price is agreed before I start.
