TV mounting in North York usually means one of two houses. A 1960s bungalow or side-split with plaster walls and solid framing, or a Yonge Street condo where the wall behind the drywall is concrete. Both hold a TV well once the right anchors go in.
I look at where you sit before I mark anything, since height matters more than most people expect. Cables get tucked into the wall when the construction allows and into a channel when it does not. Free quote first, price agreed before I start, and the room left clean.
