Condo living rooms are made for wall-mounted TVs: they save floor space and look clean. But condo walls aren’t like house walls, and condo buildings have rules houses don’t. Here’s what to know before mounting a TV in a Toronto, Mississauga, Hamilton or Burlington condo.
Step 1: Figure out what your wall is made of
Most condo units have two kinds of walls.
Concrete walls
Exterior walls, walls between units (demising walls) and walls around the core are often poured concrete. Knock on it: concrete sounds solid and dull. A magnet won’t stick, and a stud finder finds nothing.
Steel-stud drywall walls
Interior partitions between rooms are usually drywall on light-gauge steel studs. Knocking sounds hollow, and a magnet will stick to the screws along the steel studs.
Step 2: Use the right anchors
For concrete, you need a hammer drill, a masonry bit and concrete anchors such as sleeve anchors or concrete screws rated for the load. Concrete holds extremely well once the anchors are set properly. Avoid drilling near the edges of openings, and watch for rebar: if the bit hits steel, stop and move the hole slightly.
For steel studs, wood lag bolts won’t hold. Use heavy-duty toggle anchors designed for steel framing, spread across several points. For larger TVs and full-motion mounts, spreading the load across two studs is important.
Never rely on plastic drywall anchors alone for a TV.
Step 3: Don’t drill into the ceiling or floor slab without approval
Many GTA condo towers are built with post-tensioned concrete slabs: steel cables under very high tension run inside the floors and ceilings. Drilling into one can cut a tendon, which is dangerous and expensive. Most buildings prohibit drilling into slabs without approval and scanning. Ceiling-mounted projectors and TVs need a conversation with your property manager first.
Step 4: Check your building’s rules
Before booking an installer, check:
- Whether drilling into concrete walls needs notice or approval
- Permitted hours for noisy work
- Elevator booking for deliveries and contractors
- Whether contractors need to provide a certificate of insurance
- Rules about opening walls for wiring
Step 5: Plan the wiring
In steel-stud walls, cables can usually run inside the wall with an in-wall power kit, as long as the building allows it. On concrete walls, cutting a channel is rarely worth it, so the standard solution is a slim, paintable raceway from the TV down to your devices. Painted the wall colour, it’s very discreet.
Step 6: Choose the right mount for small spaces
- Fixed mount: the slimmest look, ideal when you only watch from the sofa.
- Tilting mount: good for bedrooms or higher positions.
- Full-motion mount: in open-plan condos, lets one TV face the living area or the kitchen and dining area.
If you’re renting, ask about minimal-damage options and keep the number of holes to a minimum.
When to call a professional
Concrete drilling, heavy TVs, full-motion mounts and anything near a slab are worth leaving to an installer who does it regularly.
