How to remove light fixtures, outlets and switches safely yourself: step by step

Take the devices off so the walls can be worked, and leave every conductor individually capped, taped, and labeled inside its box. Nothing new gets wired here.

Difficulty 2 of 5 · about half a day · careful

Stop here

Only with the circuit shut off at the panel and proven dead with a non-contact tester at the box itself — panel labels are wrong constantly, and a box can be fed by two circuits. Cap every wire. Stop and call a licensed electrician if: you find aluminum branch wiring, cloth-insulated or crumbling insulation, knob-and-tube, or no ground; the box is overfilled, burnt, or loose; you cannot identify which breaker feeds the box; or the work is anything other than taking a device out and putting a like-for-like device back. Moving a switch, adding an outlet, or touching the panel is a permit job for an electrician, not DIY.

What you need

  • Wire nuts, assorted (orange and yellow)
  • Electrical tape
  • Blank cover plates
  • Painter's tape and a fine marker (labeling conductors)
  • Zip bags for screws and plates

Tools

  • Non-contact voltage tester
  • Plug-in outlet tester
  • Insulated screwdrivers
  • Lineman's pliers and wire strippers
  • Headlamp
  • Phone camera (photograph every box before disconnecting)
  • Step ladder

Step by step

  1. Step 1 of 10

    Confirm the breaker for this room is off and taped

    The shutoff task did this. Confirm the tape is still on it and nobody reset it.

  2. Step 2 of 10

    Prove the tester works, then test every box

    Touch the tester to a known-live outlet elsewhere and listen for the beep. Then test each outlet, each switch, and each fixture box in this room — including the screw terminals once the device is loose.

  3. Step 3 of 10

    Photograph the box before a single wire comes off

    One clear photo showing which color goes to which screw. Label each conductor with tape: hot, neutral, switch leg, traveler, ground.

  4. Step 4 of 10

    Look at the wiring before you touch it

    Cloth insulation, no ground, aluminum conductors (dull silver, marked AL), knob-and-tube, or a burnt smell means stop and call an electrician.

  5. Step 5 of 10

    Ceiling fixtures: support the weight, then unwire

    Hang the fixture from the box with a wire hook or have someone hold it. Unwire, then unscrew the mounting strap.

  6. Step 6 of 10

    Cap every conductor individually and tape the nut

    One wire nut per bare conductor end, twisted on firmly, then a wrap of electrical tape around the nut and onto the insulation. Grounds get capped too.

  7. Step 7 of 10

    Fold the wires neatly into the back of the box

    Gentle bends, wires back against the box, nothing sticking past the face. You will be running a drywall knife across this box.

  8. Step 8 of 10

    Put a blank plate on every box

    Screw a blank cover on. Painter's tape over the plate keeps mud and texture out of the screw holes.

  9. Step 9 of 10

    Bag the devices, screws, and plates by room

    One zip bag per room with a label. If a device is being reused, note where it came from.

  10. Step 10 of 10

    Room is safe to work in

    Nothing conductive is exposed anywhere in the room.

    Quality check

    • Every conductor in every box is capped with a wire nut and taped
    • Every box has a blank cover plate on it
    • Every box was photographed and every conductor is labeled
    • No cloth, aluminum, or knob-and-tube wiring was disturbed
    • The breaker is still off and taped, with a note on the panel
    • Devices and screws are bagged and labeled by room

Common mistakes

  • Testing at the breaker instead of at the box. Old apartments are wired in ways nobody documented — a single box can be fed from two circuits, and panel labels lie. Test at every box, with a tester you just proved works on a live outlet. Mistake #1 in this task.
  • Not photographing the box before disconnecting. Three white wires and two blacks look identical in a week. One photo per box, and a tape label on every conductor, is the whole difference between a 20 minute reinstall and calling an electrician.
  • Leaving conductors bare in the box. Even with the breaker off, someone flips it back on. Cap each conductor individually, tape the nut, and fold it into the box.
  • Leaving an open box in the wall. Open boxes collect drywall dust and mud, and are an obvious shock hazard. Blank plate on every one until the new device goes in.
  • Dropping a ceiling fixture while unwiring it. Support the fixture with a hook or a helper before the last screw. Falling fixtures break and take the box with them.
  • Working around cloth or aluminum wiring anyway. Cloth insulation crumbles the moment you flex it and aluminum needs special connectors. Both are an electrician's call, not a weekend's.
