Why Granbury Homes Outgrow Their Panels
A house built in 1975 was wired for a 1975 life: one window unit, an electric range, maybe a shop light in the garage. That same house today is running central air, a tankless water heater, a pool pump, two refrigerators, and everyone's chargers — often on the same 100-amp panel it started with. Around Lake Granbury this story is everywhere, because so many of our homes began as modest weekend places and grew with each owner.
An overloaded, aging panel doesn't always announce itself. Sometimes it's obvious — breakers tripping every time the dryer and A/C run together. Sometimes it's quieter: a warm panel cover, a faint buzz, flickering when big loads start, or the discovery during a home sale that your insurer won't write the policy until the panel is replaced.
Signs It's Time to Upgrade
- Your panel is a fuse box, or a brand with a documented failure history — Federal Pacific (FPE), Zinsco/Sylvania, or Challenger.
- No open slots — or worse, tandem breakers stacked in slots that weren't designed for them.
- Breakers trip regularly when normal combinations of appliances run.
- Rust, scorch marks, or a warm cover — corrosion and heat are how panels fail.
- You're adding an EV charger, hot tub, pool, welder, or a shop building and the load calculation doesn't fit the service.
- Your insurance company or home inspector flagged the panel during a sale or renewal.
What a Panel Upgrade Includes
This isn't a swap-the-box-and-leave job. A proper service upgrade from us includes a load calculation for how you actually live, a new panel with copper bus and quality breakers, new grounding and bonding brought up to current code, AFCI/GFCI protection where today's code requires it, and clean, labeled circuits — every breaker identified, not "lights, misc." We pull the Hood County or City of Granbury permit, schedule the inspection, and coordinate the disconnect and reconnect with your utility so your power is back on the same day in almost every case.
If your meter base, mast, or weatherhead is aging too — common on older lake homes that have taken a few storms — we'll assess it while the service is already open and give you the option to address it in the same visit, when it's cheapest to do.
Straightforward Pricing on a Big-Ticket Job
A panel upgrade is real money, and it's exactly the kind of job where vague bids hide surprises. Our quotes are written, flat-rate, and itemized: panel and breakers, grounding work, permit and inspection fees, utility coordination. The number you approve is the number you pay. If we open the wall and find something genuinely unforeseeable, work stops and you get options before another dollar is spent.
Frequently Asked Questions
How long is my power off during a panel upgrade?
Plan on most of a working day. We coordinate the disconnect and reconnect with your utility and the inspection so that power is back on the same day in the vast majority of jobs.
Do I need a permit for a panel replacement in Hood County?
Yes — service equipment replacement requires a permit and inspection. We pull the permit, schedule the inspection, and handle utility coordination as part of the job.
Is my Federal Pacific or Zinsco panel really dangerous?
Both brands have well-documented histories of breakers that fail to trip under fault conditions. Many insurers now flag or decline homes with them. We recommend replacement, and we put that in writing with photos of what we found.
Should I upgrade to 200 amps if I'm adding an EV charger or shop?
Often yes, but not always — a load calculation tells the truth. Sometimes load management hardware lets your existing service handle it. We run the numbers before recommending the bigger job.
