Top Electrical Contractors in San Antonio

San Antonio’s growth (now well over a million residents) and year-round construction boom mean electrical work touches everything—new homes in Stone Oak, retrofits in Alamo Heights, restaurant build-outs downtown, and fast-growing industrial parks along Loop 410 and I-10. Add our summer heat, spring thunderstorms, and a big push toward EVs and backup power, and the stakes get real: you want wiring that’s safe, efficient, future-ready, and inspected without drama. The best San Antonio electricians bring licensed teams, clean documentation, and a “measure twice, pull permit once” mindset—so your project passes first time and performs for decades.

A quick reality check on local conditions: CPS Energy service changes and meter pulls must be coordinated; older houses often carry 60- or 100-amp panels that struggle with today’s loads; and more homeowners are stacking Level-2 chargers, heat-pump water heaters, induction ranges, and whole-home surge protection. Commercial clients are juggling arc-flash labeling, IR scans, and downtime windows measured in minutes, not hours. Great contractors turn those constraints into a plan: accurate load calcs, right-sized panels (200 amps is the modern baseline for many homes), tidy labeling, and commissioning reports you won’t lose in a drawer.

‍

San Antonio hiring checklist (save this before you call):

Licensing & insurance: Ask for the contractor’s TDLR TECL number, a Master Electrician overseeing your job, and proof of general liability + workers’ comp.
Permits & inspections: Confirm City of San Antonio DSD permits, CPS Energy coordination for panel/service upgrades, and who meets the inspector on site.
Load & capacity: Request a written load calculation (not just “it’ll fit”)—especially if you’re adding an EV charger (typical 32–48A continuous at 240V), a sauna, or a shop.
Code safety: Verify GFCI in kitchens, baths, garages, outdoors; AFCI in most living areas; proper grounding/bonding; tamper-resistant outlets in dwellings per NEC.
Panel health: Ask the age and rating of your panel; many need a 200-amp upgrade to support modern appliances. Aluminum branch circuits (common in late-’60s/’70s homes) need approved copper pigtails.
Surge & resilience: Whole-home surge protection at the service, plus point-of-use on sensitive gear; discuss generator transfer switches or interlocks (never “back-feeding”).
Warranty & documentation: Get an itemized quote, parts/labor warranty in writing, and a close-out packet: panel schedule, photos, torque logs, and inspection sign-off.
Schedule & access: Clarify outage windows, cleanup, and who patches drywall if runs go behind finished surfaces.

Choosing a San Antonio electrical contractor isn’t just about fixing a tripping breaker—it’s about safeguarding your property and the people in it. Texas law requires an electrical contractor to hold a TDLR TECL license with a Master Electrician providing oversight; in the city limits, permitted work must also pass inspection by San Antonio Development Services before CPS Energy restores service after panel changes. Asking for those credentials up front (and seeing them on the truck and proposal) is the fastest way to separate pros from pretenders.

A few practical numbers help frame decisions. Most modern homes run best on 200-amp service; older panels (60/100 amps) often choke when you add a Level-2 EV charger (commonly 32–48 amps continuous), an induction range, or a workshop. Kitchens need at least two 20-amp small-appliance circuits; baths and laundry each require their own 20-amp circuits; and bedrooms, living rooms, and halls should be protected by AFCI, while kitchens, baths, garages, and exteriors need GFCI. If your house has 1960s–’70s aluminum branch circuits, ask about approved copper-pigtail repairs using listed connectors—done right, they dramatically reduce overheating risk.

Reliability and resilience matter, too. San Antonio’s storm season can produce voltage swings and surges; a Type-1 or Type-2 whole-home surge protector at the service gear plus point-of-use protection on sensitive electronics is cheap insurance. If you’re considering a generator, insist on a transfer switch (manual or automatic)—never a dangerous back-feed—and confirm the electrician sizes gas lines and ventilation correctly. For businesses, NFPA 70E arc-flash labeling, annual infrared scans, and documented torque checks help prevent unplanned outages and protect staff.

Bottom line: the contractors featured here pair licensed craftsmanship with clear communication, tidy job sites, and warranties that mean something. Ask for a written load calc, an itemized scope, and a close-out packet with photos, panel schedules, and inspection sign-offs—you’ll thank yourself the next time you need to add a circuit. With the right San Antonio electrician on your side, your project will be safe, code-compliant, and future-ready—and you’ll enjoy the quiet confidence that comes from work done right the first time.
