Electrical Contractors in Houston , TX
Southern Electrical Services is one of Houston's most experienced licensed electrical contracting companies — self-performing commercial and industrial electrical projects of every size across the Greater Houston area since 1991. TDLR #TECL18759.
Choosing the right electrical contractor is one of the most important decisions in any commercial or industrial construction or renovation project. The wrong choice leads to change orders, delays, code violations, and long-term electrical problems. Southern Electrical Services has built its reputation over 35 years by delivering on our commitments — on time, on budget, and to code.
We're a Houston company through and through. Our crews work daily with the City of Houston and Harris County permitting offices, coordinate utility work with CenterPoint Energy, and build to the code amendments the local AHJs actually enforce. From our shop on W. Little York Road we cover the entire metro — from downtown high-rises to the Ship Channel industrial corridor to the distribution hubs along Highway 290 and the Grand Parkway.
Whether you need a commercial electrician for a tenant build-out, an industrial electrician for plant power and controls, or a design-build partner for ground-up construction, you get the same thing: our own licensed electricians, a single point of accountability, and work that passes inspection the first time.

Complete Self-Performance
We don't subcontract our core electrical work. Every licensed electrician on your project is a Southern Electrical Services employee — ensuring consistent quality, supervision, and accountability throughout your project.

Safety-First Culture
Our safety record reflects our genuine commitment to protecting our employees and your facility. We follow NFPA 70E and OSHA requirements rigorously — not just when inspectors are present.
