Whole House Rewiring Cost in Seattle

The Cost to Rewire a House in Seattle

A full whole-house rewire is a major project. In the Seattle area, the cost to completely rewire an older home typically ranges from $15,000 to $30,000+. Partial rewires start around $2,000 to $5,000.

What Factors Impact the Cost?

• Home Size and Layout: Larger homes cost more to rewire than smaller bungalows.
• Accessibility: Unfinished basements or open attics lower labor costs compared to slab foundations.
• Wall Material: Plaster walls (common in early 1900s Seattle homes) are much harder to work with than drywall. We pride ourselves on minimizing wall damage by skillfully fishing wires whenever possible.
• Panel Upgrades: A house old enough to need a rewire almost certainly needs a new electrical panel, which adds to the overall project cost.

Why Replace Knob-and-Tube Wiring?

Knob-and-tube wiring lacks a ground wire, making it extremely hazardous for modern electronics and appliances. The insulation also degrades over time. Most insurance companies in Washington State will refuse to insure a home with active knob-and-tube wiring.

The Rewiring Process

A full rewire typically takes 1 to 2 weeks. It involves carefully cutting access holes, fishing new Romex wiring through the walls, installing new grounded outlets and switches, and bringing the entire home up to current National Electrical Code (NEC) standards.
