Homes built in Western Washington before 1980 frequently contain knob-and-tube wiring, ungrounded cloth-insulated cable, or solid aluminum branch circuits — all of which are now considered fire hazards by modern insurance underwriters.
Knob-and-tube wiring features ceramic knobs that hold single conductors away from framing. The rubber and cloth insulation on these wires degrades over decades, exposing bare copper inside wall cavities where it can arc against wood framing.
Aluminum wiring, common in 1965–1975 construction, expands and contracts at connection points. Over time this loosens screw terminals on outlets and switches, creating resistive heating and arc-fault fire risks at every device.
The Insurance Problem: Many carriers in Washington now refuse to write or renew policies on homes with knob-and-tube or aluminum wiring, or they require a costly four-point inspection. Rewiring restores insurability and protects your resale value.
Our Clean Fishing Process: Bolt Electric specializes in non-invasive rewiring. We map every circuit, then pull fresh NM-B copper cable through walls using micro-openings — typically 2-inch access cuts at box locations — so your historic plaster and lath walls survive intact.
What's Included: Every whole-home rewire includes dedicated kitchen and bathroom GFCI circuits, arc-fault breaker protection for bedroom circuits, tamper-resistant receptacles, and a complete grounding and bonding upgrade to current NEC code.
If your Tacoma craftsman, Seattle bungalow, or Gig Harbor home predates 1980, a professional safety inspection is the first step. We deliver a written report with photo evidence and a clear rewire plan.
Frequently Asked Questions
Will rewiring destroy my walls?
No. We use non-invasive wire fishing techniques that keep drywall and plaster cuts to an absolute minimum — typically small access openings at box locations that are easily patched.
How long does a whole-home rewire take?
Most whole-home rewires take 2 to 5 days depending on home size, accessibility of attic and crawlspace, and the extent of the original wiring remediation needed.
