Steelcore Electric - San Marcos's Top-Rated Electrical Contractor

Yes, we frequently assist San Marcos homeowners with aluminum wiring concerns. This older wiring can indeed pose a safety risk due to connection issues. Our licensed electricians are trained to evaluate your system and recommend solutions, which may include installing specialized connectors (COPALUM or AlumiConn) at outlets and switches, or in some cases, advising on a partial or full rewiring with modern copper. Our priority is ensuring your home's electrical system is safe and up to current standards.

Our generator installation is thorough and code-compliant. We start by assessing your home's electrical load to recommend the right generator size. The process includes installing a dedicated automatic transfer switch, which safely disconnects your home from the grid and connects to the generator when power fails. We handle all permits, proper placement for ventilation and noise, and ensure a seamless connection to your main electrical panel. With our experience in both residential and complex commercial installations, we ensure your backup power system is reliable and safe.
