Knob and Tube and Aluminum Wiring Replacement in San Antonio, NM
Two kinds of old wiring cause the most concern for homeowners and insurers: knob and tube, found in homes built before the 1940s, and aluminum branch wiring, used from the mid-1960s to the mid-1970s. National Electric NM handles knob and tube wiring replacement and aluminum wiring replacement in San Antonio, NM.
Your options
Knob and tube has no ground wire and insulation that turns brittle with age, especially where attic insulation has been piled over it. Aluminum branch wiring expands and contracts more than copper, which loosens connections and creates heat. Both are common in older San Antonio neighborhoods and both can be dealt with.

Why San Antonio properties call a local electrician
Central New Mexico's high desert climate ages electrical systems in its own way. Around San Antonio, ultraviolet light breaks down exposed cable and plastic boxes, temperature swings loosen connections, and monsoon season brings surges and brief outages.
Most properties in Socorro County get their electricity from Socorro Electric Cooperative. If your project touches the meter or main service, we handle the scheduling with the utility.
We provide old wiring replacement throughout San Antonio and in nearby Claunch, Socorro, Carrizozo, and Polvadera.

Knob & Tube and Aluminum Wiring Replacement FAQs for San Antonio
Does aluminum wiring have to be completely replaced?
Not always. Replacing it with copper is the most complete fix. A recognized alternative is to repair every connection in the house with connectors made for joining aluminum to copper. We explain the cost and trade-offs of each.
Is knob and tube wiring illegal in San Antonio?
Existing knob and tube is not automatically illegal, but it cannot be extended, it should not be buried in insulation, and many insurers will not cover a home that has it. Replacement is the long-term answer.
Will replacing old wiring damage my walls?
We keep openings as few and small as we can by working from the attic and crawl space. Some patching is normal, particularly in plaster and adobe.
Which areas around San Antonio do you cover for old wiring replacement?
All of San Antonio and the surrounding Socorro County communities, including Claunch, Socorro, and Carrizozo.
