Electrical work is the one trade where "it works" tells you almost nothing. A circuit wired badly will run fine for years before it overheats inside a wall. That is why electrical work is licensed, permitted and inspected almost everywhere, and why the paperwork matters more here than in any other home repair.
This guide covers the credentials to ask for, the questions that reveal whether a business does things properly, the warning signs of a sales visit dressed up as a safety inspection, and how to compare estimates for a repair, a new circuit or a panel upgrade.
Electrical licensing is handled by the state in some places and by the county or city in others, and the titles differ: electrical contractor, master electrician, journeyman. Check the rules where you live.
Licenses, insurance and permits
Electrical contractor license
The business that contracts with you needs a contractor license, and the person doing the work needs to be licensed or supervised by someone who is. Rules vary by state. In Florida, for example, electrical contractors are licensed by the Electrical Contractors’ Licensing Board, and a license is searchable on the DBPR Verify a Licensee page. Other states, such as Washington, publish their own lookup tools. Ask for the number and check it yourself.
Journeyman or master electrician credential
Separate from the business license in many states. The person who shows up should be a licensed electrician or an apprentice working under one. Ask who will be doing the work and what credential they hold.
General liability insurance and workers’ compensation
Liability insurance covers damage to your home, including a fire traced back to the work. Workers’ compensation covers the electrician if they are hurt on your property. Ask for a certificate of insurance and check the dates and the business name.
Permits and inspections
Adding a circuit, replacing a panel, installing an EV charger, wiring a fixture where none existed and most work inside walls require a permit and an inspection. Swapping a like-for-like outlet or light fixture often does not. The permit is your proof that someone independent looked at the work.
Manufacturer or program certifications
EV charger makers, solar and battery companies, and generator brands often train and list certified installers, and some warranties depend on it. Not needed for a tripping breaker, but worth asking about for those jobs.
Questions to ask
- What is your contractor license number, and what license does the electrician who will do the work hold?
- Do you charge a service call or diagnostic fee, and is it applied to the repair?
- Will I have a written estimate before any work begins, with materials and labor shown?
- Does this job need a permit, will you pull it, and will you be there for the inspection?
- How will you diagnose a tripping breaker or a dead outlet rather than just replacing parts?
- What happens if you open a box and find aluminum wiring, a double-tapped breaker or something else that needs attention?
- What warranty do you give on labor, and for how long?
- Can you provide a reference from a similar job, such as a panel upgrade or a new circuit?
Red flags
- A free safety inspection from someone who was in the area, which always finds a panel that needs replacing today.
- Cash only, no receipt, or an invoice without a business name and license number.
- No written estimate before the work, or a verbal number that grows after the panel cover comes off.
- Full payment demanded up front. A deposit on a large job with ordered equipment is normal; the balance is paid after the inspection.
- Scare tactics without evidence: this could burn your house down tonight. Real hazards exist, and a competent electrician shows you the scorched wire or the thermal reading rather than just the fear.
- A suggestion that you pull the permit yourself as the homeowner, or that no permit is needed for work you know is inside the walls.
- Recommending a whole-house rewire or a service upgrade when you called about one dead outlet, without testing first.
Comparing quotes fairly
- Compare scope line by line: breaker brand and type, wire gauge, whether the permit and inspection are included, whether drywall repair is in or out.
- For a panel upgrade, check that each quote names the amperage, the panel brand, the grounding and bonding work, and whether coordination with the utility is included.
- Look at how each electrician diagnosed the problem. Testing and explaining beats guessing and replacing.
- Compare labor warranties and whether the business has a real address. A warranty is only as good as the business behind it.
- Ignore any number given before someone looked at the panel and the circuit. Electrical estimates depend on what is behind the cover.
On the day
- Clear access to the electrical panel, the outlets or fixtures involved, and the attic or crawl space if wires run through them. Panels need clear space in front.
- Expect the power to be off for part of the visit. Save your work, unplug sensitive electronics if asked, and plan around refrigerators and medical equipment.
- Expect a diagnosis and a written estimate before the repair starts. If the electrician finds something else, they should stop and explain before continuing.
- Ask the electrician to label any new breakers and to show you the work before the cover goes back on.
- Get an invoice that matches the estimate, with the license number, the permit number if one was pulled, and the warranty in writing. Keep the inspection record with your house papers.
Questions people ask
Can a handyman replace an outlet or a light fixture?
In some states a like-for-like swap of a device is allowed without an electrical license, in others it is not, and anything that adds or changes wiring usually requires a licensed electrician. Check your state and local rules before assuming.
Why does a permit matter for work I will never see?
Because the inspector is the only independent person who looks at it. Unpermitted electrical work can also surface during a sale or an insurance claim. The small cost of a permit is cheap insurance.
The electrician says my panel is a hazard. How do I know?
Some older panel brands have a documented history of problems, and that can be looked up. Ask for the brand and model, and get a second written opinion from another licensed electrician before paying for a replacement.
Should I pay a diagnostic fee just to find out why a breaker trips?
Usually yes, and it is money well spent. Finding the cause takes testing, and a fee that is credited toward the repair costs you nothing extra if you go ahead.
