Protect the whole house from power surges, and bring your outlets and breakers up to NEC-2023 code — permitted, inspected, and done right the first time.
The restoration surge
If you rode out Hurricane Beryl in July 2024 with the rest of us — part of the roughly 2.2 million CenterPoint outages across the region — you already know the worst part isn't always the dark days. Sometimes it's the moment the power comes back.
When a grid that's been down for days starts switching back on, the restoration isn't a clean, gentle flip of a switch. Utility switching events and the sudden return of load can push voltage surges down the line and into your house — and those spikes don't care whether you were home or not. They go looking for whatever's plugged in.
A $30 power strip protects the one device sitting behind it. It does nothing for the things you can't unplug: your HVAC control board, the well pump, the range, the smart panel, the EV charger, and the network gear running your whole home. Those are exactly the high-dollar items a restoration surge tends to find.
That's the honest case for whole-home surge protection. Not "buy now before the next storm." Just a straight look at what you stand to lose by leaving the things you can't unplug unprotected — and a fix that costs a fraction of replacing an HVAC board or a panel full of electronics.
Whole-home surge protection
Whole-home surge protection means a panel-mounted Type 2 surge protective device (SPD) installed at or in your service panel — the point where power enters the house.
In plain English: the SPD watches the incoming voltage and clamps the spikes, diverting excess energy safely to ground before it can travel through your circuits to your equipment. It sits upstream of everything, so it protects the whole house from one location instead of one device at a time.
We usually recommend layered protection: a whole-home SPD at the panel for the big, fixed loads you can't unplug, plus point-of-use protection (quality surge strips or in-wall units) for the sensitive electronics that deserve a second line of defense — your computer, AV gear, the home network. The two work together. One doesn't replace the other, and we'll tell you honestly where each one earns its keep.
Because the SPD lives in the service panel, this work pairs naturally with a panel upgrade. If your panel is older, full, or already on the list to be replaced, adding the SPD at the same time is the efficient move — see panel upgrades for that side of the job.

NEC-2023 safety layer
Surge protection guards your equipment. GFCI and AFCI protection guard your family — from shock and from electrical fire. They sound similar and get mixed up constantly (even by people who should know better), so here's the straight version:
| Attribute | GFCI — Ground-Fault Circuit Interrupter | AFCI — Arc-Fault Circuit Interrupter |
|---|---|---|
| Protects against | Shock — cuts power in a fraction of a second when current leaks to ground (a hair dryer in water, a frayed cord on a wet floor). | Fire — detects the dangerous arcing of damaged or loose wiring before it can ignite. |
| Where it's required | Wet / damp locations: kitchens, bathrooms, garages, laundry, outdoors, and more under NEC-2023. | Most living-area circuits — bedrooms, living rooms, and beyond under NEC-2023. |
| Where it lives | The outlet or the breaker. | The breaker in your panel. |
There's also a dual-function breaker that does both jobs in one device — increasingly the right answer where NEC-2023 calls for both kinds of protection on the same circuit.
NEC-2023 expanded where each is required. That matters because the honest stakes here are real, not invented: a home inspection or your insurer can flag missing GFCI/AFCI, a resale can stall over it, and the underlying hazards — shock and arc-fault fire — are exactly what these devices exist to prevent.
Here's the part a handyman often gets wrong: swapping in a "GFCI" outlet because the old one looked worn, without understanding whether that circuit actually needs AFCI, dual-function, or a breaker-level fix instead. A licensed master electrician installs the right device in the right place to code — not a guess that passes the eye test and fails the inspection. AFCI protection in particular lives in the panel as a breaker, and missing GFCI/AFCI is one of the most common things an electrical inspection flags.

If your breaker keeps tripping the moment you reset it, that can be an AFCI doing its job — or a real fault. We dig into that in Why does my breaker keep tripping?
Why TriCoast
For panel-level work we pull the permit and schedule the inspection — you don't chase the city.
The right device in the right location, installed to current code — not a best-guess swap.
TDLR EC #EECELE00037785. Local to the Galveston Bay corridor and accountable when you call back.
We stand behind the work and we pick up the phone.
If one circuit needs a GFCI and that's the whole job, that's the whole quote.
We're not always the cheapest quote you'll get — we install to code, pull the permit where it's required, and stand behind it. For high-stakes safety work, that's the part that's worth paying for.
Both techs were very knowledgeable and professional from start to finish. They left the job site clean and all work was tested and reviewed with us before they left. My wife and I were extremely impressed. I would recommend TriCoast to all my friends and family.
TriCoast did an amazing job. Donald was so polite and his wife was very quick to reply to emails and requests. We were so impressed that we will be using TriCoast Electrical Services to handle all of our electrical needs in the house we are purchasing!
Donald is the best. He is very knowledgeable in his field and listens and answers any and all questions. Thank you for getting us all fixed up!

FAQ
Yes — and it's one of the most overlooked storm risks. When the grid restores after a multi-day outage like Beryl, utility switching and the sudden return of load can send voltage spikes down the line into your home. Those surges go for whatever's connected — HVAC control boards, the range, the well pump, the EV charger, smart-home and network gear. A power strip only protects the one device behind it; a whole-home SPD at the panel protects the things you can't unplug.
GFCI protects against shock in wet or damp areas (kitchens, baths, garages, laundry, outdoors). AFCI protects against arc-fault fire on most living-area circuits and lives as a breaker in your panel. NEC-2023 expanded where each is required, and on some circuits you need both — that's what a dual-function breaker handles. Many homes genuinely need a mix. We identify which circuits need what and install to code, rather than guessing.
No — they do different jobs, and the best setup is layered. The whole-home SPD at the panel knocks down the big incoming surges and protects everything, including fixed equipment you can't unplug. Point-of-use protection (good surge strips or in-wall units) gives sensitive electronics — computer, AV, network gear — a second line of defense. We'll tell you honestly where each is worth it; we won't sell you more than the job needs.
It depends on scope. For panel-level work — installing a panel-mounted SPD, or AFCI/dual-function breakers in the panel — we pull the permit and handle the inspection; in Houston, electrical permits are issued to registered master electricians, so we do it, not you. For a like-for-like device swap the permit scope can differ. We confirm exactly what your job requires up front and never leave you to chase the city.
Yes — this is routine for us. An inspection or insurer flag (or a resale that's stalling over it) usually means specific circuits or locations need GFCI, AFCI, or dual-function protection added to meet NEC-2023. We assess what was flagged, install the correct devices in the correct places to code, and document it so the issue clears. If you'd like, we can pair it with a fuller electrical inspection.
It depends on your panel and scope — whether you need a whole-home SPD, GFCI/AFCI updates, both, or just a single circuit. So we assess first and quote with no surprise bills rather than throw a number at you sight-unseen. If the SPD is being added alongside a panel upgrade (typically $1,183–$1,972), we fold it into one clear, written quote.
FAQ "Do I need a permit for surge/GFCI/AFCI work in Houston?" — confirm exact permit applicability for SPD-only and like-for-like GFCI swaps so this answer states scope accurately and doesn't over-claim.
FAQ "How much does whole-home surge protection cost?" — confirm whether TriCoast wants to publish a typical SPD/GFCI install price range as an honest anchor. None is approved — do NOT invent one.
