Older Wiring? Get an Assessment Backed by 25+ Years in San Diego
We provide knob-and-tube wiring replacement for homes and businesses with active, altered, or deteriorated older circuits. Our licensed, bonded, and insured electrical technicians replace outdated wiring with modern, code-compliant materials while working to minimize damage to walls, ceilings, and finished spaces.
A professional assessment can determine whether visible ceramic knobs and tubes are part of an active circuit and whether targeted work or broader rewiring is appropriate. We can also evaluate related wiring or panel needs for planned improvements such as EV charger installation and smart home systems. Electrical load capacity depends on the service, panel, circuits, conductors, and connected equipment, so replacement wiring alone doesn’t automatically increase capacity.
Knob-and-tube wiring was standard in construction for homes and buildings built before the 1950s. The system gets its name from the ceramic knobs used to secure wires along framing and the ceramic tubes that protected wiring as it passed through wood.
These systems generally lack the equipment grounding conductor found in modern wiring. However, the presence of ceramic knobs and tubes doesn’t establish the condition of the entire electrical system. An electrician must determine whether the circuits remain active, have been altered, or are mixed with newer wiring.
Reasons to Investigate Knob-and-Tube Replacement
Ungrounded circuits offer less protection for connected appliances and electronics than modern grounded replacement wiring. Aging conductor insulation may also become brittle or damaged by pests, previous alterations, or contact with surrounding building materials. Exposed conductors, warm switches, flickering lights, unusual odors, or frequent breaker trips warrant a professional assessment.
Older wiring may also complicate plans for additional outlets, appliances, or other electrical improvements. Limited outlets and repeated circuit breaker trips can indicate that the property’s circuits and connected loads need evaluation. We can map circuits and coordinate related wiring or electrical panel work when the existing system can’t support the planned improvements.
Attic and insulation projects are another reason to identify active knob-and-tube wiring. San Diego Gas & Electric program installation standards place conditions on installing insulation around active older wiring, so an electrical evaluation may be necessary before that work proceeds.
Insurance requirements vary by carrier, policy, and the condition of the property. Some owners may be asked to provide documentation about whether knob-and-tube circuits are active, their condition, or completed replacement work. An assessment gives you a defined scope to discuss with your insurer rather than relying on a universal assumption about coverage.
Our Knob-and-Tube Replacement Process
Our licensed electricians can begin with a detailed assessment of your property’s wiring, looking for immediate hazards and factors that may affect replacement. Depending on access and the property’s construction, this may include the electrical panel, branch circuits, outlets, attic spaces, crawlspaces, and previous alterations. From there, we can develop a tailored replacement plan and walk you through the work before installation starts.
The required scope may range from replacing affected circuits to a broader rewire, depending on the wiring’s condition and the property’s electrical requirements. We can explain the expected work and identify related circuit or panel needs before installation starts. When electrical permit support is required for the approved scope, we can address it as part of the project planning.
During replacement, we can remove outdated wiring and install modern, grounded wiring in accordance with relevant electrical codes. Our team can work methodically to minimize disruption to walls, ceilings, and finished spaces wherever possible.
Once the work is done, we can test the completed installation to confirm it’s functioning safely and correctly. We can answer your questions throughout the project and explain any changes to the plan. Clear communication, transparency, and safe workmanship are qualities many customers have praised. We’re also a BBB-accredited business.

"I couldn’t be happier."
I have a plug-in hybrid and decided to install a 240 outlet for it. I called this morning, and Robert arrived at 2 to give me a free estimate. I knew about what it should cost, and his estimate was so good that I didn’t ask for the new customer discount. He installed it right below my panel, and I couldn’t be happier. I will recommend them to anyone needing an electrician. Thanks, Rober!
