Knob-and-Tube Wiring Replacement in Buffalo: questions
Do I need a permit for knob-and-tube wiring replacement in Buffalo?
Usually, yes. Electrical permits inside the city come from the City of Buffalo's Department of Permit and Inspection Services; suburbs such as Amherst and Cheektowaga issue their own. New York has no statewide electrician license, and Buffalo licenses electricians locally. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Buffalo?
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.
