How to Install a Wall Sconce in a Stairwell

Locate the main electrical panel and identify the circuit breaker that controls the power to the stairwell area. Flip the breaker to the 'Off' position. Use a non-contact voltage tester to confirm that power is indeed off at the intended work location before proceeding.

Decide on the desired height for the sconce, typically around eye level or slightly higher on the wall. If replacing an existing fixture, use that as a guide. If running new wiring, determine the most appropriate location for a new electrical box, ensuring it is centered and level where the sconce will attach. Use a pencil to lightly mark the center point for the mounting bracket or electrical box.

If running new wiring, use a drywall saw to cut an opening for an 'old work' electrical box. Feed the electrical cable through the box's knockout and secure it. Mount the electrical box firmly to the wall framing or joists. If using an existing box, ensure it is securely fastened and suitable for the weight of the sconce. Remove the appropriate knockout from the box for the wire to enter.

Carefully pull the electrical cable from its source (e.g., ceiling fixture, switch, or junction box) through the wall cavity to the installed electrical box. Leave sufficient slack (about 6-8 inches) of wire extending from the box. Strip about 3/4 inch of insulation from the ends of the black (hot), white (neutral), and green or bare (ground) wires using wire strippers.

Align the mounting bracket that came with the sconce over the electrical box. Use the provided screws to attach the bracket firmly to the box. Ensure the bracket is oriented correctly according to the sconce manufacturer's instructions, usually with a designated top or bottom.

Connect the wires from the sconce to the corresponding wires from the electrical supply. Typically, this involves connecting the black wire from the sconce to the black (hot) wire from the supply, the white wire from the sconce to the white (neutral) wire from the supply, and the green or bare ground wire from the sconce to the ground wire from the supply. Use wire nuts to secure each connection, ensuring they are twisted on tightly.

Carefully tuck the connected wires back into the electrical box, ensuring no wires are pinched. Align the sconce fixture with the mounting bracket and secure it using the screws or other hardware provided with the sconce. Ensure the fixture is flush against the wall and firmly attached.

Screw the recommended type and wattage light bulb into the socket. If your sconce includes a glass shade or fabric cover, carefully attach it according to the manufacturer's instructions. Ensure the shade is properly seated and secured.

Return to the electrical panel and flip the circuit breaker back to the 'On' position. Test the sconce by operating the light switch. The sconce should illuminate. If it does not, turn the power off again and recheck all wiring connections.

Wipe down the sconce and the surrounding wall area to remove any dust or fingerprints. If any minor drywall damage occurred during installation, apply spackle or joint compound, sand smooth when dry, and touch up with paint to match the wall color.
