Knob and Tube and Aluminum Wiring Replacement in Dona Ana, 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 Dona Ana, 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 Dona Ana neighborhoods and both can be dealt with.

Why Dona Ana properties call a local electrician

Dona Ana has long, hot summers and mild winters, so cooling equipment does most of the electrical work. Panels in direct sun run hot, exposed conduit and cable degrade, and afternoon thunderstorms in monsoon season deliver frequent surges.

Electric service in Dona Ana County is typically provided by El Paso Electric. For work on the service entrance or meter, we arrange the disconnect and reconnect with them so you do not have to.

Our old wiring replacement covers all of Dona Ana, along with neighboring Fairacres, Las Cruces, Mesilla, and Radium Springs.

Knob & Tube and Aluminum Wiring Replacement FAQs for Dona Ana

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 Dona Ana?

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.
