What are the biggest red flags when hiring an electrician?

Electrical work has the highest stakes of any residential trade — fire, electrocution, and permit-fail liability all flow from the same job. The red flags below have a heavy weighting because the downside is not "the work looks bad" but "your house burns down" or "your insurer denies the claim."

Code-violation theater. The electrician opens a panel or junction box and immediately announces that prior work was performed "unsafely" or "to old code" and the whole panel/whole house needs to be rewired. Most of the time, the cited violations are either non-issues (grandfather clauses) or trivial fixes (adding a knockout plug). A real electrician explains the code citation by article number (NEC 250.x, 314.x, 408.x) and tells you which items must be brought to current code (safety) vs. which are grandfathered (legal). If the proposed scope leaps from a $200 outlet replacement to a $12,000 panel upgrade and the explanation is "it's all to code violations," get a second quote.

No permit. Any panel upgrade, new circuit, service entrance work, or sub-panel addition requires a permit in nearly every jurisdiction. An electrician who proposes to skip the permit because "the inspector won't know" is shifting permit-fail liability to you — when you sell, refinance, or have an insurance claim, the unpermitted work surfaces and becomes your problem. Walk away.

Missing or wrong license class. The electrician shows up but cannot produce a license number, or the license is for low-voltage / telecom / sign work only, not full electrical. Verify at the state board (CSLB for C-10 in California, TDLR Master Electrician in Texas, Florida EC, Oregon BCD) and confirm the qualifying party name matches the person on site.

Master vs. qualifying party mismatch. The license belongs to a Master Electrician you've never met, and the actual work is being performed by an unsupervised apprentice or unlicensed worker. Master Electricians who "rent" their license to lower-tier operators is a known pattern; the state board can suspend the license but rarely catches it before damage is done.

Cash only, large upfront deposit. Any electrician asking for more than 10-15% upfront (or above the state legal cap — California caps at 10% or $1,000, whichever is less) and demanding cash is preparing to disappear. Credit card or check creates a paper trail.

No itemized estimate. "Trust me, it'll be around $X" is not a quote. A real estimate breaks out materials (by item, with manufacturer/model) and labor hours.

Refrigerant/topping-off-style language. A real electrician will not "top off" or "refresh" electrical components — the closest analog is panel cleaning, which is also rarely a real service. If the pitch is for routine "electrical maintenance" beyond breaker exercise and thermal scan, it's likely upsell.

Groundcheck (earthmove.io/trust) verifies the license, surfaces prior complaints and citations, and runs phoenix-company detection across the state electrical board, court records, OSHA, and BBB. It does not verify the electrician's specific code interpretation — second-quote any large scope.
