Why knob-and-tube wiring replacement comes up in Norfolk
Ghent, Colonial Place, Park Place and Riverview hold many of Norfolk's homes from the 1890s to the 1920s, and knob-and-tube wiring still turns up in some of them. Tidal flooding and humidity are hard on old insulation in crawl spaces and basements. Raised foundations give the electrician a route below the floor.

Knob-and-Tube Wiring Replacement in Norfolk: questions
Do I need a permit for knob-and-tube wiring replacement in Norfolk?
Usually, yes. Norfolk is an independent city, and electrical permits come from its permits office. Virginia licenses electricians through DPOR. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Norfolk?
If the work affects the meter or service, the electrician coordinates with Dominion Energy, 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.
