How to Run the Cord Behind a Brick Wall for a Plasma TV
Running cabling for a plasma through a brick mantle can be challenging, but is not impossible. (fireplace image by askthegeek from

Many people like the appearance of a plasma or other flat screen TV over the fireplace. Many fireplaces are designed as the focal point in a room, making it a logical mounting location. The problem, though, is hiding wires behind brick and stone. Most fireplaces have a sufficient gap behind the brick facade and the metal flue to run a reasonable amount of wiring; the trick is access.

Skill level:
Moderately Challenging

Things you need

  • Flexible fish tape
  • 2-inch masonry (carbide) hole saw
  • Electrical tape
  • 1-inch masonry drill bit

  1. 1

    Drill a hole using the masonry hole saw bit in the desired location for wires to pass through the front of the brickwork. Typically, this will be a position centred behind the TV when mounted.

  2. 2

    Drill a one-inch hole just below the surface of the wall where the wires will protrude. Insert the flexible flex tape through the two-inch hole on the front of the fireplace, angling the head of the tape such that it exits through the smaller hole on the side.

  3. 3

    Tape the wires to the fish tape, now protruding through the side of the fireplace/wall junction. Retract the fish tape carefully back behind the brick facade and through the two-inch hole on the front of the fireplace.

Tips and warnings

  • Only use inwall rated cabling for this type of installation. Should something catch fire, the jacketing on this type of cable will not emit harmful noxious gasses.
  • It is not code compliant to run a power cord or extension through the mantle. An outlet must be relocated to behind the plasma on the mantle, or you must purchase an outlet extension kit.
  • Do not drill through the metal flue. Although it should be obvious when the drill bit hits this, penetrating the flue can result in heat escaping into the wall cavity or room, causing a potential fire or carbon monoxide hazard.
