Round Rock homeowner guide · Updated July 2026
Round Rock's electrical work splits between full '90s panels meeting EV-era loads and an older core with wiring from another era. How to buy both kinds of work well.
Round Rock's electrical demand curve bent upward faster than its housing stock anticipated. The '90s subdivisions were wired for a pre-EV, pre-induction, pre-home-office world — their 150-amp panels arrive full just as owners want chargers and heat-pump water heaters. The older core near downtown carries the previous era's questions: '70s-'80s panels of vintage brands, sparse circuits, and sometimes aluminum branch wiring. Texas licenses electricians, so verification is easy; matching the work to your house's era is the part that takes judgment.
In '90s-2000s stock: breakers tripping when the microwave and toaster share a kitchen circuit (code-minimum circuit counts), full panels blocking new circuits, and builder-grade devices wearing out — loose, sparking receptacles are replacement candidates, not curiosities. In the older core: warm plates, flickering tied to appliance startup, two-prong outlets, and panels that any local electrician will recognize by brand as evaluation-worthy. Reviewers of Round Rock's better shops specifically mention code-update candor on older houses — the honest ones tell you what's urgent versus what's merely dated.
Round Rock's commute economy makes Level 2 chargers the most-requested project in the trade. The sequence that avoids surprises: load calculation first (in writing), then the honest answer about your panel — many '90s 150-amp panels take a charger easily with a load-management device; full panels need an upgrade or smart splitter. Get the permit; charger circuits are exactly the work permits exist for. If a bid skips the load calc and quotes off the phone, that's the tell.
Corridor storms take out electronics here every spring, and the winter-outage memory keeps generator interest steady. Whole-home surge protection at the panel is an hour's install and cheap insurance; reviewers mention post-storm surge repairs often enough to make it a standing recommendation. For generators, a proper inlet and interlock or transfer switch — installed and permitted — is the difference between backup power and a hazard; local reviews describe exactly this work done well, sometimes days before a storm.
License number (verify with TDLR), scope in circuits and amperage, permit handling for panels and new circuits, materials grade, workmanship warranty. Hourly shops: rate and trip fee stated plainly. Flat-bid shops: itemized. Both models work; opacity in either doesn't. For older-core houses, prefer bids that price an evaluation first over bids that price a rewire off a walkthrough.
| Common job | Low | Typical | High |
|---|---|---|---|
| Service call / diagnostic | $95 | $180 | $275 |
| Ceiling fan or fixture install | $120 | $220 | $400 |
| Level 2 EV charger circuit | $450 | $900 | $1,800 |
| Whole-home surge protection | $300 | $500 | $800 |
| Panel upgrade (200A) | $2,000 | $3,200 | $5,000 |
It's the breaker doing its job on a code-minimum '90s kitchen circuit. The fix is an added circuit, not a bigger breaker — never upsize a breaker on existing wire.
Not automatically. A licensed evaluation distinguishes urgent items (certain vintage panels, damaged wiring, ungrounded circuits in wet areas) from merely dated ones. Price the evaluation, then decide from evidence.
With panel capacity available, most Round Rock installs land in the $450–$1,800 band including permit. A needed panel upgrade adds $2,000–$5,000 — which is why the written load calculation comes first.
