Rewiring Older Homes in Spokane, WA

Knob-and-tube

This early system uses separate wires on ceramic knobs and tubes. Its insulation can become brittle, it has no ground, and it was never meant to be buried in insulation. Some insurers ask about it.

Cloth-covered and early cable

Wiring from the 1920s to 1950s may have cloth insulation that cracks with age and heat.

Signs of trouble

Two-prong outlets, frequent trips or blown fuses, warm switches, flickering lights and a patchwork of old and new wiring in the basement or attic.

Partial or full rewire

Some homes need only certain circuits replaced; others benefit from a full rewire, often combined with a panel upgrade.

Protecting plaster

Electricians use existing paths, closets and basements where possible to limit cuts in plaster walls. Some patching is usually needed.

Insurance and sales

Buyers' inspectors and insurers often flag old wiring. Having it assessed lets you plan before a deadline.

Permits

Rewiring needs a permit and inspection, which gives you a record of the work.

Get an assessment

Tell the electrician the age of the home and what you've noticed. Send a request and an electrician will get in touch.

After the rewire

Keep the permit, inspection record and a panel directory listing every circuit. Insurers, buyers and future electricians will all find it useful.

Insulation and old wiring

Knob-and-tube wiring relies on air around the wires to shed heat. Blowing insulation into walls or attics over it can cause overheating, so have the wiring checked before adding insulation.

Phasing the work

A full rewire can be done in stages, starting with the kitchen, bathrooms and the circuits that see the heaviest use.
