About

Power up with safe, reliable electrical work for homes, businesses, and big projects. We’re licensed, experienced, and ready to help with every job — small or large.

Humble Beginnings of WSI Southwest

Founded in 2004 as a one-person operation in rural New Mexico, WSI Southwest began with a simple commitment: deliver honest, high-quality electrical work the right way, every time. What started as Williamson Services has grown into a respected, full-service electrical contractor serving communities across southern New Mexico (including Silver City, Cliff, Grant, Luna, Hidalgo, and Catron counties) and southeastern Arizona.

Growth and Commitment of WSI

Over two decades, we’ve expanded our expertise to handle residential repairs, commercial installations, industrial projects, mining support, and specialized services like generator setups and fiber optic cabling. Yet we’ve never lost our small-town roots—every job remains personal, every client matters, and safety is always our top priority. Today, as a licensed and insured contractor, we proudly power the homes, businesses, and industries that keep our region thriving. We’re more than electricians; we’re neighbors invested in building stronger, safer communities.
