Why knob-and-tube wiring replacement comes up in Syracuse

Heavy snow country means many owners want more attic insulation, and insulating over live knob-and-tube is not recommended, so replacement usually comes first. Basements and attics give the electrician routes for new cable, and two-family homes are rewired one unit at a time.

Knob-and-Tube Wiring Replacement in Syracuse: questions
Do I need a permit for knob-and-tube wiring replacement in Syracuse?
Usually, yes. Electrical permits in Syracuse come from the city's permit office; surrounding towns issue their own. In New York, electrician licensing is handled locally. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Syracuse?
If the work affects the meter or service, the electrician coordinates with National Grid, which owns the meter and service drop.
Is knob-and-tube wiring illegal?
Existing knob-and-tube is generally not illegal, but it cannot be extended, and many insurers and lenders treat it as a reason to replace.
Can knob-and-tube be insulated over?
It is not recommended, and many codes and insulation programs prohibit it, because the wiring relies on open air to cool.
How do I know if mine is still live?
An electrician can test it. Many homes have a mix of active and abandoned knob-and-tube.
How long does replacement take?
From a few days for a small home with good access to a few weeks for larger plaster-walled homes.
