Panel upgrades
La Marque has a lot of older housing stock, and older homes run out of panel before they run out of needs. If yours is full, warm, or tripping, this is where it starts.

What we do here
Electrician La Marque homeowners actually call us for.
Three jobs make up most of what we do here — and each one has a La Marque wrinkle worth knowing. We won't re-explain the whole job on this page; the deep service page does that. Here's the honest version, with real cost ranges so nobody gets ambushed by sticker shock:
EV charger installs
In the Houston area, only a registered master electrician can pull the permit for a Level-2 charger — the homeowner legally can't. That's us, and we run a load calculation before we ever talk panel upgrade.
$552–$1,379 typical EV charger installationWhole-home generators
After Beryl, backup power stopped being a luxury here. Automatic transfer switch, sized to run for days, no fiddling in the storm.
Whole-home generator installationWe also handle surge/GFCI protection, grounding, lighting, inspections, and commercial work for La Marque's industrial-adjacent small businesses — see commercial electrical.
Storm-ready backup power
Storm-ready whole-home generators for La Marque.
When Hurricane Beryl hit in July 2024, CenterPoint reported roughly 2.2 million outages across the region — and plenty of La Marque families went days in the dark and the heat. As one Houston-area homeowner put it after a storm, "the last thing I want to do in a storm is go out and fiddle with transfer switches."

Automatic
transfer switch — your house switches itself over
That's exactly the point of a whole-home standby generator with an automatic transfer switch: the power goes out, your house switches itself over, and it keeps running for days. No going outside, no manual switchover. Our customers describe the payoff in one word — peace of mind, like insurance for the house. La Marque sits in a part of the corridor where deep generator help is genuinely hard to find, and that's a gap we fill.
Panel safety
Is your panel safe? Panel upgrades in La Marque.
A lot of jobs here start with a worry, not a wishlist: the breakers keep tripping, the panel feels warm, or you tried to add a circuit and got told "the panel is full."
Older La Marque homes sometimes still carry Federal Pacific (FPE/Stab-Lok) or Zinsco panels — the kind insurers now flag and ask you to replace because the breakers don't always trip and can cause a fire. If your insurer called out your panel, that's a real, time-sensitive reason to act — not a manufactured one. We do 200-amp service upgrades, handle the CenterPoint coordination for you, and run a load calculation first so you only pay for the capacity you actually need.

The trust part
Permits pulled, no upsell — the trust part.
Here's the part most people don't know, and it's worth saying plainly: in Houston-area jurisdictions, only a registered master electrician can pull the electrical or EV permit — the homeowner legally can't. That's us. We don't hand you a permit application and disappear; we pull it, schedule the inspection, and see it through to a pass. Skipping the permit is where it comes back to bite you: insurers can deny a claim tied to unpermitted work, jobs can fail inspection, and unpermitted electrical can stall a home sale at closing.

We don't have a La Marque-specific review to feature here yet — so here are real, verified reviews of TriCoast Electrical from across the Galveston Bay / South Houston corridor (not La-Marque-specific):
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.

Questions, answered
Frequently asked questions.
Do I need a permit for electrical work in La Marque?
Yes, for most panel, EV, and generator work — and in the Houston area the electrical permit is issued to a registered master electrician, not to the homeowner. We pull it and schedule the inspection as part of the job, so unpermitted work doesn't come back to haunt you at claim time or resale.
How much does a panel upgrade or EV charger cost in La Marque?
Honest ranges: a panel upgrade typically runs $1,183–$1,972, and an EV charger install $552–$1,379. We quote on the actual job after we see it — no guess-quotes, any service-call fee disclosed when you book, no surprise bill. You should pay what's fair, and you shouldn't get gouged.
Will you tell me if I don't actually need a panel upgrade for my EV charger?
Yes. We run a load calculation first to verify whether your panel can already handle the charger before we ever quote you an upgrade. Many homes don't need one. See EV charger installation.
My panel is old or full — is it safe?
Maybe not. Older Federal Pacific (FPE/Stab-Lok) and Zinsco panels are the kind insurers now flag for fire risk. If yours is full, warm, or tripping, we'll assess it and, if it's warranted, do a 200-amp upgrade to code — with the CenterPoint coordination handled for you.
Can a whole-home generator keep my La Marque house powered through a storm like Beryl?
Yes. We install whole-home standby generators with an automatic transfer switch — so there's no going outside to fiddle with anything during the storm — sized to run your home for days. See generator installation.
