Why knob-and-tube wiring replacement comes up in Long Beach
Bluff Park, Belmont Heights and California Heights hold many of Long Beach's Craftsman and Spanish Revival homes from the 1910s to the 1930s, and some still have knob-and-tube wiring in attics and walls. Insurers and buyers frequently ask about it. Raised foundations give the electrician a crawl space route, and the attic handles ceiling fixtures.
California Heights and other neighborhoods are historic districts that review exterior changes. A rewire is the time to add grounded outlets and AFCI and GFCI protection. Permits come from the City of Long Beach's development services, and Southern California Edison coordinates service work.

How the work is done

2. Plan the routes
New cable routes are planned through attics, basements and walls to minimize openings.
3. Install new circuits
Grounded cable, boxes and devices are installed and the old wiring is disconnected.
4. Inspect and patch
Rough-in and final inspections are completed, and access holes are patched.
What moves the price in Long Beach

Knob-and-Tube Wiring Replacement in Long Beach: questions
Do I need a permit for knob-and-tube wiring replacement in Long Beach?
Usually, yes. Long Beach is its own city with its own building department, and electrical permits come from Long Beach Development Services rather than the City or County of Los Angeles. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Long Beach?
If the work affects the meter or service, the electrician coordinates with Southern California Edison, 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.
