How to Hide TV Wires Above a Stone or Brick Fireplace

Setting a display above a stone, brick, or concrete fireplace is one of the trickiest installs in any home. You can't just fish cables through the wall like you would with drywall. There's no cavity. So how do you get a clean install with zero visible wires?

The wrong way: surface raceways

Big-box installers love plastic surface raceways painted to "blend in." They never blend in. They sit on top of the stone like a scar, and they always look like an afterthought.

The right way: side-channel routing

We route cables through the side wall adjacent to the fireplace, then bring them back through behind the display using a low-voltage bracket. The cables never touch the masonry. From the front, the installation looks completely wireless.

What we install behind the display

• Recessed in-wall power outlet (code-compliant, no extension cords behind a display, ever)
• Low-voltage HDMI/Ethernet pass-through bracket
• Optional: in-wall HDMI extender if the source equipment is in another room
• Heat-rated cabling rated for fireplace proximity

Heat is the real enemy

The bigger problem above a fireplace isn't aesthetics, it's heat. Most panels are rated to 95°F operating temp. A flue heat shield plus a real measurement of mantel-to-display distance is non-negotiable. We measure heat output before sign-off.

When you should not mount above a fireplace

If your mantel is shallow and the fireplace puts out serious heat, we'll tell you to place the display elsewhere. We'd rather lose the upsell than warranty-replace a high-end OLED in 18 months.
