Mounting a TV over a fireplace and hiding the wires: what to know
In brief: A TV over the fireplace can look great if you get three things right: heat (check the wall above the mantel), height (consider a pull-down mount so you aren't looking up), and wiring (use an in-wall rated power kit, never a regular power cord inside the wall).
1. Check the heat
TVs don't like heat. Before mounting, find out how warm the wall above your fireplace gets when the fire is going. A wood-burning fireplace with no mantel is the riskiest; a gas fireplace with a deep mantel is usually fine. A mantel helps by deflecting heat away from the TV. If the wall is too hot to keep your hand on comfortably, the TV shouldn't go there. Check the TV manufacturer's guidance as well.
2. Get the height right
The most common complaint about fireplace TVs is neck strain, because the screen ends up much higher than eye level. Options:
- Mount it as low as the mantel allows, and tilt it down slightly.
- A pull-down mount lets the TV sit high when it's off and come down to eye level when you're watching. It's the best of both worlds for fireplace walls.
3. Mount it securely
- Drywall over studs: the mount must be attached to the studs, not just the drywall.
- Brick and stone: use proper masonry anchors, and drill into solid brick or stone for strength. Brick and stone fireplaces are some of the strongest walls to mount on when it's done right.
- Never drill into the flue or chimney cavity, and never route wires through the chimney.
4. Hide the wires the right way
A clean install has no visible cables. But there's a right and wrong way to do it:
- Don't run a regular TV power cord inside the wall. Standard power cords aren't rated for in-wall use and it isn't up to code.
- Use an in-wall power kit or a recessed outlet installed behind the TV, so power is in the wall properly.
- Run HDMI and Cat6 through the wall (ideally in a conduit) down to the media cabinet or across to a nearby closet, so the cable box, streaming device, and receiver are out of sight.
- On brick or stone where you can't go inside the wall, a cleanly painted surface raceway or routing cables behind the mantel can work.
5. Don't forget the sound
TV speakers are weak, especially when the TV is up high. A soundbar mounted below the TV, or in-ceiling speakers for a cleaner look, makes a big difference. Sonos soundbars and surrounds are a popular choice and tie into whole-home audio. See our home theater page.
When to hire a professional
A fireplace installation combines heavy lifting, masonry, in-wall power, and cable routing, which is why many homeowners hand it off. A professional installer will confirm heat clearance, mount securely into studs or masonry, and deliver a clean, code-compliant result with the audio set up properly.

Frequently asked questions
Is it safe to mount a TV over a fireplace?
Often, yes, if the wall above the fireplace stays cool enough. A mantel helps deflect heat. Check the temperature with the fireplace running and follow the TV manufacturer's guidance.
Can you hide TV wires in the wall?
Yes. HDMI and network cables can run inside the wall, and power should be provided with an in-wall rated power kit or recessed outlet. Running a regular power cord inside the wall isn't up to code.
How high should a TV be over a fireplace?
As low as the mantel allows, ideally tilted down. A pull-down mount lets the TV drop to eye level while you watch.
