Knob-and-Tube Wiring Replacement in Stamford: questions
Do I need a permit for knob-and-tube wiring replacement in Stamford?
Usually, yes. Electrical permits come from the City of Stamford's building department. Connecticut licenses electricians through the Department of Consumer Protection. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Stamford?
If the work affects the meter or service, the electrician coordinates with Eversource, 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.
