How to Hide TV Cables in the Wall (The Right Way) — 2026 Guide

You've just had your new TV wall-mounted, and it looks incredible — until you notice the bundle of cables hanging down the wall. Nothing ruins the sleek look of a wall-mounted TV faster than dangling wires. In-wall cable management is the professional solution, and in this guide we explain how it works, what's involved, and when you need a licensed electrician versus a TV mounting specialist.

Why In-Wall Cable Management is Worth It

A wall-mounted TV with cables dangling down defeats much of the purpose of mounting it in the first place. In-wall cable management:

• Creates a completely clean, showroom-quality finish
• Eliminates tripping hazards from cables on the floor
• Protects cables from being damaged by foot traffic or pets
• Adds value and a premium feel to your living space
• Is one of the most common requests we get from our clients

What Cables Need to Be Hidden?

For a complete, clean install, you'll typically need to hide:

• Power cable: The TV's mains power cable
• HDMI cables: Connecting set-top box, streaming device, gaming console, Blu-ray player
• Optical/RCA audio cables: If running audio to an external amplifier or soundbar
• Ethernet cable: If you prefer wired internet for your smart TV
• Soundbar cable: If the soundbar is wall-mounted and needs a power or HDMI-ARC cable

The Professional In-Wall Method

Professional in-wall cable management involves routing cables inside the wall cavity between the TV position and the equipment shelf or powerpoint below. Here's how our team does it:

• Step 1: Mark the cable entry and exit points — typically one hole behind where the TV will sit and one at the equipment shelf level below.
• Step 2: Check for obstructions — wall studs, fire blocking, insulation — using a stud finder and inspection camera if needed.
• Step 3: Cut neat, clean holes at both points using a hole saw or drywall saw.
• Step 4: Fish the cables through the wall cavity using a cable fishing rod.
• Step 5: Install cable management face plates at both holes for a clean, professional finish.
• Step 6: Connect all devices and confirm everything works before leaving.

What About Power? Do I Need an Electrician?

This is the most important question. In Australia, routing a standard power extension cable or using an in-wall power kit (which connects to an existing powerpoint via a low-voltage cable rather than a mains cable) does not typically require a licensed electrician. However, installing a new powerpoint inside the wall requires a licensed electrician.

At MountPro Solutions, we use approved in-wall power solutions that are compliant and safe. If you need a new powerpoint added behind your TV, we can refer you to a trusted local electrician or coordinate this alongside your mounting job.

Is It Possible in All Walls?

In-wall cable management works best in standard plasterboard walls over a hollow cavity — which is the most common wall type in Sydney's residential properties. It becomes more complex (but often still possible) in:

• Brick walls: No cavity, so cables must run in conduit on the wall surface or be chased into the masonry.
• Walls with fire blocking: Older homes may have horizontal timber fire blocks in the wall cavity that prevent cables running straight through. Workarounds are available.
• Concrete walls: Requires surface-mounted conduit or specialist chasing.
