Knob and tube wiring was common in homes built before the 1950s. It lacks a ground wire, degrades over time, and can create serious fire and shock risks when it contacts insulation or gets overloaded. King Electric and Solar helps Auburn-area homeowners understand what they have and replace it safely.
We handle the full scope of knob and tube rewiring, from initial assessment through final inspection, for homes across Auburn, Roseville, Rocklin, and surrounding communities.
Full identification and mapping of existing knob and tube circuits
Safe removal of degraded wiring throughout the home
Installation of grounded, code-compliant modern wiring
Panel evaluation and upgrades when existing capacity is insufficient
Restoration of walls and ceilings where access was needed
Final electrical inspection coordination with local authorities
Service available across Auburn, Grass Valley, Folsom, and Lincoln

Rewiring an older home is a significant project. Here is how King Electric and Solar approaches it from start to finish.
A licensed electrician visits your Auburn-area home to locate all knob and tube wiring, document its condition, and identify any immediate safety concerns before work begins.
We walk you through what needs to be replaced, how access will be handled, and what the project timeline looks like. No surprises once work starts.
Our team removes the old wiring and installs grounded modern circuits throughout the home. If your electrical panel needs upgrading to support new circuits, we handle that as part of the project.
Once the rewiring is complete, we coordinate with local inspectors to confirm the work meets current California electrical code before we consider the job done.
Find clear answers about service options, scheduling, preparation, and what to expect before you request an estimate.
Q1
Existing knob and tube wiring is not automatically illegal, but it cannot be covered with insulation and does not meet modern code. Most insurers and lenders require it to be replaced before a policy is issued or a home sale closes.
Q2
Homes built before the 1950s are the most likely candidates. Visible ceramic knobs and tubes in the attic or basement are a clear sign. A licensed electrician can confirm what you have during a home assessment.
Q3
It can be. The insulation on knob and tube wire becomes brittle with age and can crack or crumble. Contact with attic insulation is a known fire risk, and the lack of a ground wire creates shock hazards.
Q4
Many insurers in California either refuse coverage or charge significantly higher premiums for homes with active knob and tube wiring. Replacing it often makes a home insurable at standard rates.
Q5
The timeline depends on home size and complexity. A typical single-family home in the Auburn area takes several days to a week. We confirm the estimated timeline before starting any work.
Q6
Yes. King Electric and Solar serves Roseville, Rocklin, Folsom, Lincoln, Grass Valley, Nevada City, El Dorado Hills, and the broader Placer County region.
Q7
Some wall or ceiling access is often necessary depending on the home's construction. We use techniques to minimize damage where possible and clearly explain what to expect before the project starts.
Q8
Yes. Older homes with knob and tube wiring often have undersized panels that cannot support a modern electrical load. We can assess the panel and upgrade it as part of the same project.
