Electrical Inspection Before Buying an Older Seattle Home

If you are buying an older Seattle-area home, a dedicated pre-purchase electrical inspection is less about whether the wiring is dangerous and more about whether you can insure and finance the house at all. Roughly 40% of King County single-family homes were built before 1960, and three conditions common in that stock, active knob-and-tube wiring, a Federal Pacific or Zinsco panel, and a service under 100 amps, are automatic homeowner's insurance declines in this market. Konsker Electric delivers a paid, documented condition report with photos, NEC and WAC 296-46B citations, severity rankings, and flat-rate repair quotes as a written PDF within 24 hours. Licensed through Washington State L&I, bonded, insured, and BBB A+ rated. Call (206) 260-1981.

What Does a Pre-Purchase Electrical Inspection Cover

The inspection begins at the service entrance and meter base, then works inward through the main panel and every subpanel, the wiring and grounding system, and the permit trail. Every accessible junction box is opened, every panel is thermal-scanned under load, and every finding leaves with a photo and a code citation attached. We pull the Seattle DCI permit history and cross-check the King County Recorder before we arrive. See our documented code-compliance inspection service for the full scope.

Why Federal Pacific, Zinsco and Old Panels Fail Insurance

Seattle-area carriers treat three conditions as automatic declines: a Federal Pacific Stab-Lok or Zinsco panel, active knob-and-tube wiring, and a service under 100 amps. After the 2023 non-renewal wave tightened underwriting across Washington, underwriters routinely demand a written electrical condition report before binding on a pre-1985 home. What clears a flag is a permitted, inspector-finaled correction, and we explain the panel side in our Federal Pacific and Zinsco panel hazard guide.

Knob-and-Tube Wiring: What the Inspection Checks

Knob-and-tube itself is not automatically a violation, but knob-and-tube in contact with thermal insulation is, under NEC 394.12, and it is the single most common reason a Seattle insurance application is denied. We check the attic and open accessible junction boxes to document whether the wiring is dead and abandoned or still energized, then hand you an itemized flat-rate remediation quote.
