How to Conceal Electrical Wires with Crown Molding
Ask This Old House master electrician Scott Caron uses crown molding to conceal wiring and bring more electrical outlets to a bedroom
- Turn off power at the circuit panel and use a voltage tester to ensure power is fully off.
- Begin to install the crown molding by snapping a chalk line three inches down from the ceiling all around the room. That will serve as a guide to mount the molding track.
- Insert a screw to secure the track every three feet using fasteners and a drill/driver.
- Above an existing outlet, drill a hole in the track using a spade bit. This will allow the wires to be fished up from the existing outlet to the new track.
- Fish new wires from existing outlet up through the new hole in the track.
- Run wire around track by screwing it in with a zip tie every few feet.
- When you’re ready to add a new outlet in one spot, drill another hole using a spade bit into the track, then cut out an outlet hole using an oscillating saw.
- Fish two sets of wire down the wall to the new outlet hole--one to feed the new outlet and one to continue feeding power to the other outlets on the circuit.
- Seal wire holes with flexible putty.
- Measure your crown molding lengths, subtracting for the prefabricated corners, and make a straight cut.
- Install the crown molding pieces and any prefabricated corner pieces or keystones to join longer lengths.
- With the crown molding in place, finish off each outlet by making the proper wire connections. Tie ground wires together, using a special wire nut that allows one wire to come out and tie to the ground screw on the outlet.
- Neutral white wires connect to the silver screws and black hot wires connect to brass screws.
- Cover the outlets with an outlet plate.
- Turn the power back on at the circuit panel.
