Finishing

TV wire hiding kit builder

A complete parts list both ways — inside the wall for an invisible finish, or a paintable raceway with no cutting — with the right cable length worked out for your run.

Cable lengths include routing slack, a foot per bend and a service loop.

Is there an outlet behind the TV?

Measure along the route the cable would really take, not straight through the wall.

From the back of the TV down to the console or cabinet below.

HDMI devices (console, streamer, receiver)

Which route do you want?
Masonry changes this

You cannot fish a cable through solid brick or concrete the way you can through a stud bay. On masonry the real options are a surface raceway, or cutting a channel into the wall and plastering over it — a different job entirely.

There are two honest ways to hide TV cables: inside the wall, where nothing shows but you need two openings and a proper power kit, or in a paintable raceway on the surface, which takes twenty minutes and comes off clean. Which is right depends on the wall, the outlet and how much you mind a slim channel.

Getting the cable length right

Measure the drop from the back of the TV to the console, plus the run to the outlet if it is not directly behind. Then add slack: routing is never as straight as the tape, every bend costs about a foot, and the mount needs a loop behind the panel so it can move without tugging the plugs.

Up to about 15 feet a certified 48 Gbps copper HDMI cable is reliable for 4K120. Beyond that, buy optical-fibre HDMI — the cheapest insurance against a picture that drops out once the wall is closed.

What electrical code says

Low-voltage cables (HDMI, ethernet, optical, speaker wire) can run inside the wall. The TV's power cord cannot: the code requires in-wall rated cable, which is what an in-wall power kit provides — an inlet behind the TV, a rated cable in the cavity and an outlet by the equipment.

Frequently asked questions

Can I run a TV power cord inside the wall?
No. Ordinary appliance cords are not rated for in-wall use and it is a fire risk and a code violation. Use an in-wall power kit, which puts rated cable in the wall with proper boxes at both ends.
Can HDMI cables go inside the wall?
Yes. HDMI is low-voltage and fine inside the cavity. Buy one rated for in-wall use (CL2 or CL3), and for runs over about 15 feet choose optical-fibre HDMI.
How do I hide TV wires without cutting the wall?
A paintable cable raceway: stick it to the wall from the TV down to the outlet or console, run the cables inside and paint it to match. It is the right answer for renters and masonry walls.
How long should my HDMI cable be?
Measure the run, then add about 20% plus a foot per bend and two feet of service loop. Buy the next standard length up. The builder above does the arithmetic for you.
Can you hide TV wires in a brick wall?
Not by fishing them — there is no cavity. Either use a surface raceway or cut a channel into the brick and plaster over it, which is a much bigger job. Most brick installs use a raceway painted to match.

Rather not open the wall?

We run the cables inside the wall with a rated power kit for $69 per TV, or in a surface raceway for $39, alongside any mounting job.
