Knob and tube wiring replacement in Plainfield

The first step is finding what is actually live. Houses are often partly rewired, and old runs get spliced into new ones. We trace each circuit, disconnect the knob and tube, and run new grounded cable to every device it served. Dead wiring left inside walls is disconnected at both ends.

We also get calls from Plainfield for old house wiring replacement, knob and tube rewiring and knob and tube removal. If you are not sure which one you need, describe the problem and we will tell you.

  • New grounded circuits to replace each run

Knob and tube wiring replacement in Plainfield: 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.

Do you have to open the walls?

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

What customers say

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

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

We had an inspection done before buying a 1920s house. The report was clear about what was urgent and what could wait, and nobody pushed us to do any of it.
