Why knob-and-tube wiring replacement comes up in Hartford
Hartford's West End, Asylum Hill and Frog Hollow are full of Victorians and three-family houses built from the 1880s to the 1920s, and knob-and-tube wiring still runs through many of them. Three-family homes are usually rewired one unit at a time, using basements, stacked wall cavities and attics. Connecticut's weatherization programs generally will not insulate over live knob-and-tube, which prompts many owners to replace it.
The West End is a historic district. Permits come from the city's licenses and inspections office, and Eversource coordinates service work.

Knob-and-Tube Wiring Replacement in Hartford: questions
Do I need a permit for knob-and-tube wiring replacement in Hartford?
Usually, yes. Electrical permits in Hartford come from the city's Licenses and Inspections division; West Hartford and other towns issue their own. Connecticut licenses electricians through the Department of Consumer Protection. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Hartford?
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.
