How do I hang a heavy overmantel mirror safely?

Large overmantel mirrors require robust wall fixings into masonry or direct attachment to timber wall studs using heavy-duty brackets. Due to the substantial weight of the timber carcass, glass plate, and gesso ornament, professional installation ensures the frame remains secure against the wall.
