Mounting a Big TV on Brick: What Brisbane Installers Do That DIYers Don't
Brisbane's solid-brick walls crack mortar when you pick the wrong anchor. Here are the three steps our installers follow on every 75-inch brick job — and where we walk away.
Brisbane has a brick problem. A good one, if you’re a mason — a painful one if you’re trying to hang a 40-kilogram TV on Saturday morning with a cordless drill and a 60-pack of plastic anchors from the hardware store. Our installers handle two or three brick jobs a week across New Farm, Bulimba, Paddington and Bardon, and the mistakes we get called out to fix are almost always the same three.
This post walks through what actually works on Brisbane brick: how to diagnose the wall, which anchor survives ten years of tilting and kids and humidity, how to get cables out of sight without a jackhammer, and what the job costs in 2026. We’ll also flag the brick jobs we quietly refuse to take on — because walking away from a wall is cheaper for everyone than fixing it later.
Why brick breaks DIY installs
There are three failure modes we see on DIY brick jobs, and they all come from the same root cause: treating brick like a thicker, angrier version of plasterboard.
Mortar blow-out. The softest part of a brick wall is the mortar joint — which is exactly where most DIY guides tell you to drill “for an easier start”. On an older Brisbane home, anything pre-1980, the mortar is often lime-based and crumbly. A standard plastic wall-anchor will bite for six months, then the joint weeps under vibration every time someone walks past the wall.
Face-spalling. Drilling into the face of a brick with a masonry bit should work. It does, until the bit hits an air pocket inside a fired brick and the face pops off like a chipped tooth. On a painted feature wall that’s a $200–$600 repair job before we can even fit the bracket.
Pin-anchor creep. The sleeve anchors sold in bulk at the hardware store are rated for soft clay — not for the rigid, aggregate-heavy bricks used on most Brisbane inner-suburb renovations. Over twelve months they wind backwards out of the hole every time the TV is tilted. By month eighteen, the bracket is swinging.
None of these show up on day one. They all appear six to twelve months in, which is why you rarely see them in DIY YouTube videos — by the time the wall fails, the creator has moved on to their next “one weekend project”.
The right anchor for Brisbane brick
Before we pick a fastener, we work out what the wall actually is. In Brisbane that’s usually one of three things.
Double-brick with a cavity. Common on older Queenslanders that have had the original timber cladding replaced, and on post-war red-brick homes around Wilston and Ashgrove. Two solid skins of brick with a ~50mm air cavity between them. Rock-solid if you hit it right.
Single-skin brick veneer. Very common on 1970s–1990s homes across the south side. It looks like a double-brick wall from the outside; inside, it’s a single skin of brick tied to a timber stud frame. Drilling into the brick alone here is a trap — the fixing has to reach the timber stud behind.
Rendered cement block. More common in unit complexes and newer builds through South Brisbane, West End, and Fortitude Valley. Hollow-core blocks behave differently to solid brick and need their own anchors.
Each wall type takes a different fastening strategy. For double-brick we use a chemical anchor — an epoxy-resin capsule that bonds a threaded rod into the brick itself, rated up to about 200kg pull-out on a single fixing. For single-skin veneer we go through the brick into the timber stud behind, using a long lag bolt with a nylon sleeve at the brick face so the stud does the load-bearing work, not the skin. For rendered block we use specific cavity-fix anchors with a wide collar that can’t crush into the hollow core.
Getting that diagnosis right is 80% of the job. An apprentice with the right anchor will beat a master tradie using the wrong one, every time.
Getting cables out of sight — without cutting the wall
This is the part most customers don’t think about until we’re halfway through. You can’t “fish” cables inside a brick wall the way you can inside plasterboard. The brick is solid; there’s nowhere for the cable to go.
There are three honest options on a brick wall.
- Channel and chase. We cut a shallow vertical channel into the brick or mortar line, drop the cables in, then patch with matching mortar. Clean look, permanent, but adds about an hour to the job and needs proper dust extraction. On heritage-listed properties it may also need council sign-off before we touch the wall.
- Surface conduit. A slim white conduit that sits flush against the wall and can be painted to match. Invisible from across the room; visible if you’re looking for it up close. Our go-to for renters who aren’t allowed to chase the wall.
- Over-mantel routing. If the TV is going above a fireplace — which is roughly a third of our brick jobs — we often run power and HDMI behind the mantel itself, then down through an existing chimney flue. No new holes in the face of the wall.
We walk every brick customer through all three before we quote. Pretending there’s a magic “cable runs invisibly inside the wall” option on a solid-brick install is the single fastest way to go over budget.
What we charge, and what we won’t do
Brick adds roughly 30–50% to a standard TV wall-mount price at Brisbane TVs. Full pricing is on the TV wall-mounting service page and the cable-concealment service page, but the short version is:
- Simple brick mount, no cable concealment — from $249
- Brick mount with surface-conduit cable run — from $349
- Chased-in cable concealment (double-brick) — from $449
- Large screens (75”+) or above-fireplace — quoted on site
There are a few brick jobs we won’t take.
We won’t mount onto unreinforced single-skin veneer unless we’ve positively located studs behind it. We don’t guess. We’ll stand in your living room with a stud finder and, if we can’t find a fixable point within reason, we’ll tell you and walk away. You don’t pay for the callout.
We also won’t bury a power lead inside a chased channel unless a licensed electrician is on site — that’s a legal requirement in Queensland, not a Brisbane TVs policy. If you need power relocated, we bring a sparky or we reschedule the day.
Brick-wall FAQ
Can you mount on a painted brick feature wall without damaging the paint?
Usually yes, if the paint is acrylic and has been on for more than a year. We tape, drill through the tape, and pull it away with the dust. Chalky or limewash finishes are harder, and we’ll flag the risk on site before we drill so there are no surprises.
What about a 100kg outdoor TV on an exterior brick wall?
We do these, mostly around the river in Bulimba and New Farm. Chemical anchors only, and we want to see the wall first — exterior walls carry weather loading as well as the TV weight, and the bracket specification shifts with the TV size.
Do you do brick jobs same-day?
Not usually. Brick jobs get a site visit first if anything about the wall is uncertain — it saves both of us turning up on the day and discovering a hollow block or a heritage mortar line. For straightforward double-brick we can normally book same-week.
How long does the whole install take?
About 90 minutes for a standard brick mount, 2.5–3 hours if we’re chasing cables into the wall and patching the mortar afterwards.
Will the fixings rust?
Not if we spec them right. We use stainless or galvanised rod on any wall within 5km of the river — Brisbane humidity eats cheap fasteners inside two summers, and a rusted fixing is the other common reason we get called back to fix a brick job.
