Call nowThe San Antonio metro is not one housing market, it is several stacked on top of each other. A 1920s bungalow in Monte Vista, a 1968 ranch in Castle Hills, a 2019 build in Cibolo, and a well-fed house on acreage outside Boerne all need a different first move. We size the work to the property in front of us rather than quoting from a menu.
Permits and inspections
Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.
What's covered
Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.
What is different about electrical services in Texas.
Some of what we do for electrical services is shaped by the codes and conditions specific to Texas. Here is what tends to differ versus other states.
Code adoption in Texas
Texas adopts the National Electrical Code at the state level through the Texas Department of Licensing and Regulation, with most cities in the San Antonio metro adopting the most recent NEC cycle within a year or two of publication. Schertz, New Braunfels, Cibolo, and the other cities we cover each maintain their own permitting offices with slightly different inspection scheduling and form workflows. We track which cycle each AHJ in our coverage area is currently enforcing, so the scope we write for a job in Schertz is current to that city, not just current to "Texas." When a project crosses jurisdictions or sits in unincorporated county, we route the permit through the correct authority and tell you upfront which inspection cadence applies.
Hot-climate considerations
Summers across the San Antonio metro run long and hot, and that affects electrical services in ways that are easy to underestimate. Panels mounted on west-facing exterior walls run hotter all afternoon. Attic-mounted equipment derates per code because ambient attic temperatures regularly clear 130°F. AC compressors pull near-rated current for hours at a stretch through July and August, which puts more thermal cycling on terminations than the same equipment would see in a milder climate. We size conductors and breakers with that summer load profile in mind, not just the nameplate minimum. On older homes we look closely at terminations that may have loosened from years of heat cycling, those are a common cause of intermittent issues that get misdiagnosed elsewhere.
Severe weather and storm response
The metro sees thunderstorm hail, the occasional derecho, and the post-storm spike in generator and surge-protection demand that comes with each event. We keep enough surge-protection inventory at the shop to swap out a damaged whole-home unit same-day after a strike, and we know which generator and transfer-switch SKUs are realistic to source quickly when the supply chain tightens after a regional event. After the 2021 winter storm we also got a lot more careful about which loads customers actually need on backup, versus which loads end up on the generator only because nobody asked the question at install time.
