Why Knob-and-Tube Hazard Mitigation Is Critical for Your Home
Knob-and-tube wiring was installed in homes built from the late 1800s through the 1940s. While functional in its era, vintage knob-and-tube wiring lacks equipment grounding, relies on asphalt-saturated cloth insulation that disintegrates over time, and was designed for low-amperage loads. Today, covering knob-and-tube conductors with attic insulation or powering modern appliances creates severe thermal hazards and fire risks.
As licensed residential electrical contractors, HB Electric Solutions provides complete hazard mitigation and circuit replacements across Tacoma and Pierce County. We safely isolate, decommission, and replace ungrounded legacy circuits with modern, grounded copper wiring—protecting your home while satisfying stringent insurance mandates.

Our Replacement & Hazard Mitigation Process
Upgrading vintage wiring demands careful execution to preserve your home’s architectural finishes while modernizing your power grid.
01
Circuit Tracing & Load Audit
We map out your existing electrical network using non-destructive circuit locators, pinpointing active knob-and-tube runs and illegal junction box splices.
02
Non-Invasive Wire Routing
Modern grounded copper cables are drawn through basement joists, attic cavities, and wall channels to connect every switch, outlet, and fixture.
03
Panel Connection & Municipal Inspection
New circuits are tied into your distribution panel with proper arc-fault and ground-fault protection, followed by a final city or county inspection.

Frequently Asked Questions
Is knob-and-tube wiring dangerous if it has not caused issues yet?
Yes. Age alone makes knob-and-tube wiring hazardous. The cloth insulation surrounding the copper wires becomes brittle and flakes away, leaving exposed bare metal behind walls. Additionally, because the system lacks a grounding wire, sensitive electronics and appliances are unprotected from power surges and shock hazards.
Why do insurance companies mandate the replacement of knob-and-tube wiring?
Insurance underwriters view knob-and-tube as a high-risk liability due to its age, lack of grounding, and vulnerability to overheating—especially when modified over decades by previous homeowners or buried under thermal insulation. Replacing the system brings the home up to modern safety standards and removes coverage restrictions.
Can you replace knob-and-tube wiring without destroying historic plaster walls?
Yes. We specialize in non-invasive wire-drawing techniques. By accessing wall cavities through attic spaces, basements, and small opening points behind trim or existing outlet boxes, we pull modern conductors into place without tearing down plaster or lathe.
How long does a complete knob-and-tube replacement take?
For a standard single-family home, complete replacement and circuit modernization typically take between 3 to 5 days, depending on home size, attic access, and total circuit count.
