Why knob-and-tube wiring replacement comes up in Waco
Castle Heights and Sanger Heights hold many of Waco's homes from the 1900s to the 1940s, and knob-and-tube wiring still turns up in some of them, especially in houses that sat for years before Waco's renovation boom. Pier-and-beam foundations give the electrician a crawl space route for new cable. Renovated homes sometimes have new wiring in the kitchen and old wiring elsewhere.
Insurers often ask about knob-and-tube. Permits come from the City of Waco's inspection services, and Oncor coordinates any service change. Ask for the work documented.

Knob-and-Tube Wiring Replacement in Waco: questions
Do I need a permit for knob-and-tube wiring replacement in Waco?
Usually, yes. Electrical permits inside city limits come from the City of Waco's inspection services. Texas licenses electricians through the Texas Department of Licensing and Regulation (TDLR). The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Waco?
If the work affects the meter or service, the electrician coordinates with Oncor (lines and meters); retail provider of your choice, 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.
