Finding a reliable commercial electrician in Houston shouldn't be hard. Southern Electrical Services has been the electrical contractor that Houston businesses call first since 1991 — handling everything from a small tenant improvement to a full building re-wire. Our licensed electricians work efficiently and professionally, minimize disruption to your operations, and deliver work that meets or exceeds code requirements the first time.

We work across the full range of Houston commercial property — office towers and single-tenant buildings, retail and restaurants, healthcare and medical office, hotels and hospitality, schools and government buildings, and the warehouse, distribution, and light manufacturing space that surrounds the city. Whether you're a property owner, building engineer, general contractor, architect, or end-user, we bring the same crew discipline and code knowledge to every project.

As a 35+ year Houston contractor, we know the local AHJs (City of Houston, Harris County, and the surrounding municipalities), the utility coordination process with CenterPoint Energy, and the code interpretations that matter for a smooth inspection. That local knowledge is worth real money when it shortens a schedule or avoids a costly re-do.

FAQ

Frequently Asked Questions

What does a commercial electrician do that a residential one doesn't?

Commercial buildings run on bigger services (typically 200A–4000A versus a residential 100A–200A), three-phase power, larger conduit and conductor sizes, more demanding code requirements, and more complex lighting and life-safety systems. A commercial electrician is trained in the design, code, and execution of those systems — and in working around occupied tenants, after-hours coordination, and the documentation a commercial landlord or AHJ expects.

Do you handle tenant build-outs and white-box conversions?

Yes — tenant improvement work is a large share of what we do in Houston. That includes white-box-to-finished build-outs for offices, restaurants, retail, medical/dental, and light industrial. We coordinate with your GC, architect, and the building engineer; pull permits; and deliver on the schedule your lease commitments require.

Can you upgrade or replace an existing commercial electrical panel?

Yes — service entrance upgrades, main switchboard replacements, sub-panel additions, and code-compliance retrofits are routine for us. We coordinate the utility outage with CenterPoint Energy (or your local utility), handle permitting, and schedule cutover work to minimize disruption — typically nights or weekends for occupied buildings.

Are you available for after-hours work to avoid disrupting our tenants or operations?

Yes — most of our occupied-building work is scheduled evenings, weekends, or holiday hours. We crew accordingly, lock out and tag out properly, and clean up so the space is ready for the next business day.

Do you handle the city permits and inspections?

Yes — we pull permits with the City of Houston, Harris County, or whichever AHJ has jurisdiction, schedule the inspections, and walk the inspector through the work. Building owners and GCs get a clean turnover packet at the end of the job.

Can you install EV charging stations for our employees or customers?

Yes — Level 2 and DC fast charging installations for parking lots, parking garages, and dedicated fleet locations. We size the service, run the conduit and feeders, install the EVSE units, and coordinate with utility rebate programs where they apply.

How quickly can you respond to a commercial electrical emergency?

We answer the emergency line at (713) 660-7344 any hour. For Greater Houston we typically have a licensed electrician on-site within an hour of dispatch. For surrounding service areas (Pasadena, Pearland, Conroe, Sugar Land, The Woodlands), usually within 90 minutes.
