Knob and tube wiring replacement across New Jersey
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.
What is included
- Tracing of all live knob and tube circuits
- New grounded circuits to replace each run
- Removal of accessible old wiring in basements and attics
- Correction of old-to-new splices
- A letter describing the work for your insurer
- Permit and inspection

- The job is inspected, and we walk you through the finished work.
Knob and tube wiring replacement cost in New Jersey
The cost to replace knob and tube in New Jersey depends on how much is still live and how easy it is to reach. A house with a few remaining circuits is a very different job from one that was never updated.
Knob and tube wiring replacement: 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.
