Knob and tube wiring replacement in Mendham: common questions

Is knob and tube wiring illegal?

No, existing installations are allowed to remain. But it cannot be extended, it should not be covered with insulation, and many insurers will not accept it.

Can I insulate over knob and tube?

No. The wiring relies on open air to stay cool. Replace it first, then insulate.

Less than you might think. Most new cable is fished from the basement and attic.

What customers say

Our insurer wanted the knob and tube gone. They traced what was still live, replaced it with hardly any wall damage and wrote the letter the insurance company asked for.

Rachel G., Montclair

Our house had aluminum wiring and the outlets were getting warm. They went through every box in the house and explained both options and the price for each. Very straight with us.

Tom R., Cherry Hill

Half the house went dark on a Sunday night. They picked up on the second ring, told me which breaker to switch off and had someone here that evening. It was a burnt connection in the panel, fixed on the spot.
