Why knob-and-tube wiring replacement comes up in Indianapolis
Irvington, Woodruff Place, Herron-Morton and the Old Northside are full of homes from the late 1800s and early 1900s, and knob-and-tube wiring is still found in many, sometimes buried under attic insulation. Quick renovations sometimes leave it hidden behind new drywall, which is why buyers ask about it. Basements and attics give the electrician routes for new cable.
Several of these neighborhoods are historic districts that review exterior changes. Permits come from the Department of Business and Neighborhood Services, and AES Indiana coordinates any service change. Ask for the work to be documented.

Knob-and-Tube Wiring Replacement in Indianapolis: questions
Do I need a permit for knob-and-tube wiring replacement in Indianapolis?
Usually, yes. Indianapolis and Marion County share a consolidated government, and electrical permits are issued by the Department of Business and Neighborhood Services. Beech Grove, Lawrence, Southport and Speedway run their own permitting. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Indianapolis?
If the work affects the meter or service, the electrician coordinates with AES Indiana, 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.
