Will you have to open up the walls?

Sometimes. Many rewires can be done with minimal wall damage by routing cable through attics, basements, and crawl spaces. When wall openings are necessary, we keep them as small as possible and discuss the plan with you before we cut.

How long does a rewire take?

Timeline depends on the size of the home, the wiring type being replaced, and how much access we have. We'll give you a timeline as part of the written quote.

Does a rewire need a permit?

Yes. Rewiring requires a permit. Crescent files the permit and schedules the inspection.

Home Rewiring & Old Wiring

Old Wiring Replacement for Palouse Homes

When your home has old or failing wiring, we'll walk through it with you and lay out the options.

Many homes around Moscow and the Palouse still have wiring from the 1950s, 60s, or 70s: knob-and-tube in farmhouse attics, aluminum branch wiring in postwar neighborhoods, and two-prong outlets without a ground. Crescent replaces old wiring with grounded, code-compliant cable built for today's loads.

Or call (509) 903-9411

Old wiring is not always an emergency, but it needs a real look before remodel work, panel upgrades, insulation, or a sale. Crescent can identify what is in the walls, explain what needs replacement, and phase the work when a full rewire is not necessary. Call (509) 903-9411 if you want Crescent to check what wiring is actually in the walls.

Old wiring, grounded circuits, and cleaner access

Many older homes on the Palouse have wiring that predates today's electrical codes. A rewire replaces aging cable, outlets, and devices with modern, code-compliant materials. It improves safety, reduces fire risk, and adds capacity for modern loads like HVAC, appliances, and home electronics.

Knob-and-Tube ReplacementWiring installed before the 1950s. It lacks a ground, struggles with modern loads, and can be flagged by some home insurance carriers.
Aluminum Wiring RemediationAluminum branch wiring, common in homes built in the 1960s and 70s, can fail at the connections over time. Code-approved fixes are available.
Ungrounded OutletsOlder homes with two-prong outlets can be brought up to grounded, three-prong service through rewiring or properly installed GFCI protection.
Whole-Home RewiresFull replacement of the wiring inside the home. Done all at once during a remodel or gradually, one circuit at a time.
Permits and InspectionRewiring requires a permit and inspection. Crescent handles the permit paperwork.
