Stop first if

  • Insulation cracks when handled.Stop handling it, leave the circuit off and have a licensed electrician assess it.
  • Plates run warm or there is a burning odor.Stop the work and call a licensed electrician. With smoke or active odor, leave and call emergency services.
  • Live knob-and-tube wiring runs in a cavity due for insulation.Hold the insulation work until a licensed electrician deals with the wiring.

Ask on the call

Homeowner? These are the questions a good technician will ask you. Having the answers ready makes the first visit count.

  1. What are you replacing, and what would you like in its place?
  2. About how old is the house, and has it been rewired?
  3. What does the wiring look like where you can see it, such as cloth, metal sheath or dull gray?
  4. Have you noticed warm plates, or devices that quit?
  5. Is insulation going into these walls or ceilings?

  1. A licensed electrician confirms the circuit is dead by test. An electronic off is not isolation.
  2. Identify each wiring era in view. Houses often mix eras.
  3. Do not flex brittle wiring. Note cloth or rubber insulation that cracks.
  4. For a new ceiling or canless light, read the cable temperature marking at the box before mounting.
  5. Where wiring is aluminum, use only devices marked for it. Ordinary copper-only devices do not belong there.
  6. Note old insulation cooked by heat from a fixture.
