Knob and tube rewiring in Manville
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.

Knob and tube wiring replacement in Manville: 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.
