What should I ask before hiring an electrician?
The three questions that matter most: Are you licensed in this state and will you pull permits? Is the diagnostic fee credited toward the repair? What specifically are you seeing that makes you recommend X? Unpermitted electrical work is uninsurable and fails home inspections — any electrician who suggests skipping permits should be skipped instead.
The most common electrician scam is recommending a whole-home rewire from a single bad outlet. A licensed electrician should be able to isolate the problem with a circuit trace and show you exactly what they found before expanding scope.
The questions that separate pros from problems
Are you a licensed electrician in this state, and will you pull permits?
License lookup: free; permits: $75–$300Good answer sounds likePanel work, new circuit runs, and EV charger installs require permits in virtually every jurisdiction. Unpermitted electrical work is uninsurable and creates liability at resale.
Walk away if…Ask for the license number and check your state contractor board. For panel work, confirm the permit will be pulled before demo starts — not after.
Is your diagnostic fee credited toward the repair if I approve the work?
$75–$150 diagnosticGood answer sounds likeMost electricians charge $75–$150 for a service call. Many credit it toward the repair; some don't. The ones who don't are running a different kind of business.
Walk away if…Ask before scheduling. Get it in writing if they say yes.
What exactly are you seeing that requires that repair?
Second opinion: worth the service call feeGood answer sounds likeA whole-home rewire recommendation from one bad outlet is a documented scam — get a second opinion. A legitimate electrician traces the circuit, uses a non-contact voltage tester and circuit tracer, and shows you exactly what's wrong before recommending scope expansion.
Walk away if…Ask them to walk you through their diagnostic steps. Vague answers like 'old wiring' without specifics are a signal to call another company.
Do you carry general liability and workers' comp insurance?
No cost to verifyGood answer sounds likeElectrical fires are the leading cause of home fires. If an uninsured electrician causes a fire or is injured on your property, you may be liable.
Walk away if…Ask for a certificate of insurance (COI). Call the insurer to confirm it's active. Takes five minutes.
What panel do I have, and is it one you'd flag as a safety concern?
Panel replacement: $1,800–$4,000Good answer sounds likeFederal Pacific Stab-Lok and Zinsco panels are documented to fail to trip under overload — they're a genuine fire hazard. A knowledgeable electrician knows these on sight.
Walk away if…If you have one of these panels, replacement is the right call. But an honest electrician raises this proactively — they don't wait to be asked.
How long have you worked in this area and can you provide references?
No cost to checkGood answer sounds likeLocal electricians have relationships with local inspectors and know jurisdiction-specific quirks (permit timelines, inspection requirements). References from recent jobs confirm they finish cleanly.
Walk away if…Ask for two or three recent customer references in your area. Any hesitation is a red flag.
Before you even call
- Check your panel before calling — open the door and look for any breakers that are warm to the touch, smell like burning plastic, or are in the off position. Note the brand (Federal Pacific, Zinsco, Square D, Leviton, Siemens) — this affects what questions to ask.
- Describe the problem with specifics: which circuit, which outlet, when it started, whether it correlates with a specific appliance or weather event. Electricians diagnose faster with context.
- Look up the electrician's license on your state contractor board before they arrive — takes two minutes and tells you if the license is active, bonded, and has complaints filed.
- Confirm you know the location of your main breaker shutoff. In any electrical emergency, knowing how to cut power to the whole house is the most important thing.

Red flags that end the conversation
- Any electrician who recommends a whole-home rewire based on a single problem area without a full circuit trace — get a second opinion first.
- They suggest skipping the permit to 'save you time' on panel work, new circuit runs, or EV charger installation.
- They can't explain in plain terms what they found and why the specific repair they're recommending fixes it.
- They won't provide a written quote before starting work.
About pricing
Electrical quotes should break out labor from materials and specify exactly which circuit, panel slot, or device is being addressed. For panel work, the quote should include the permit fee and inspection process — not just the hardware. For EV charger installs, confirm whether the quote includes the dedicated circuit run and any panel capacity upgrade needed. Vague quotes like 'electrical work — $X' with no breakdown are how overcharges happen.

Related questions
Does an electrician need to be licensed for outlet and switch work?
Licensing requirements vary by state and municipality. Panel work, new circuits, and EV chargers require licensed electricians nearly everywhere. Simple outlet or switch replacements may fall under homeowner DIY exemptions in some states, but if you're hiring someone to do it, they should be licensed. Unlicensed electrical work can void homeowner's insurance coverage for any resulting fire.
How much of a deposit should an electrician require?
For service calls and small repairs, no deposit is standard. For large projects (panel replacement, whole-home rewire), 25–33% upfront is reasonable. Never pay more than 50% before work begins, and never pay the full amount until you've seen the completed permit inspection pass.
How do I verify an electrician's insurance?
Ask for a certificate of insurance showing general liability (minimum $500K) and workers' compensation. Call the insurer on the certificate directly to confirm it's active — the COI can be fake. This takes five minutes and matters a lot if anything goes wrong during the job.
Will electrical work come with a warranty?
Licensed electricians typically warrant their labor for 1–2 years and pass along manufacturer warranties on parts (breakers, panels, devices). The warranty should be stated in writing in the contract. 'We stand behind our work' without a time frame or scope is not a warranty.
