Neighborhood note

When San Marcos customers reach out about surge protection and grounding, the first conversation is about scope and timeline, not just price. We tell you the version that fits the project, the version that does not, and where the breakpoints actually sit. The Austin shop runs trucks through San Marcos regularly, so the install timing usually lines up with our existing schedule rather than waiting on a one-off trip.

Permit and inspection

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.

Warranty

What's covered

Lifetime warranty on surge protection and grounding systems. Parts and labor. Stays with the home and transfers to the next owner.

05 - WHO TO HIRE

Why hiring a licensed electrician matters.

For surge protection and grounding, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.

Keil Electric

A licensed electrician

Licensed electrician walks every job. Veteran-owned, family-run.

Permits pulled and inspections coordinated when required by the AHJ

5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.

Fully insured + workers' comp on every crew

The price you sign is the price you pay

A handyman

Unlicensed for electrical

No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.

No permits. Work won't pass inspection if the city audits it later.

No structured warranty. "Call me if something breaks" isn't enforceable.

If something they did causes a fire, your homeowner's insurance can deny the claim.

Cash discount may show up on the invoice.

DIY

Doing it yourself

Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.

A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.

No warranty if something fails. Replacement is on you.

Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.

If you know what you're doing, fine. If you don't, call us first.

Across San Marcos, TX, Keil Electric runs surge protection and grounding as part of our regular Austin service area coverage.

What we see for surge protection and grounding in San Marcos

San Marcos is a Hays County city with a Texas State University campus, downtown housing (historic to mid-century), substantial student-rental properties, and newer subdivisions on the edges. surge protection and grounding jobs span historic rewires, mid-century panel upgrades, multi-unit and rental-property work, and newer-construction additions.

How surge protection and grounding typically runs in San Marcos

Surge protection and grounding cover whole-house surge protective devices (Type 1 at the service entrance, Type 2 at the panel, layered with point-of-use strips at sensitive equipment) and grounding electrode work (ground rod installation, water-pipe bonding, panel bonding correction). SPDs catch utility-side switching events, induced lightning surges, and transients from large-motor cycling. Grounding work corrects the most dangerous and most common deficiency in older homes, a fault that should clear in milliseconds becoming a shock hazard or fire risk.

Permits and code in Texas

Austin metro cities pull permits through their own AHJs (the city of Austin uses Austin Energy and the city development services; outlying cities run through the county). The state adopts the National Electrical Code with Texas amendments. We pull the permit when the scope requires it, schedule any inspection, and close out the work in your file. San Marcos-specific permit notes go on the quote so you know what is required before any work begins.

Calls from this page reach the Austin team directly. San Marcos is part of our day-to-day coverage, dispatched from our Round Rock shop with the same crew that runs every other Austin-area job. After-hours emergencies are dispatched when capacity allows; routine jobs are usually scheduled within a few business days depending on parts and scope.

Common questions for Surge Protection and Grounding in San Marcos

Does Keil Electric install whole-home surge protection in San Marcos?

Yes. Type 2 SPD at the main panel, plus point-of-use protection on sensitive circuits. Our Austin team installs Square D, Eaton, or Siemens devices.

How much does whole-home surge protection cost?

Surge protection is bid by panel size and equipment selection. The price is in writing before the install. Most jobs are a single-day visit.

Will the surge protection stop a lightning strike?

A direct strike is more energy than any standard residential surge device handles. Whole-home SPD reduces utility-side surges, transformer spikes, and most weather-related transient events. Direct lightning protection is a separate scope (lightning rods, dedicated grounding) that we do not currently install.

Do I need to upgrade my grounding?

Sometimes. A current-code grounding system is two grounding electrodes plus a bond to the water service. Many older San Marcos homes have one ground rod or a deteriorated bond. We verify the system before installing surge protection and correct what is needed.

How long does the install take?

Most whole-home surge installs are a single-day visit (a few hours). Grounding correction adds a few more hours depending on access to the grounding electrode.

Is there a warranty?

Lifetime written warranty on whole-home surge protection paired with verified grounding. 10-year on grounding correction. Parts and labor. Stays with the home.
