10 Questions to Ask Before Hiring an Electrician

Why the Right Questions Matter

Electrical work is one of the few home improvement categories where hiring the wrong person can burn your house down. That's not hyperbole — the National Fire Protection Association attributes roughly 46,000 home fires per year to electrical failures or malfunctions. The electrician you hire needs to be competent, properly credentialed, and accountable for their work.

Before you hand over access to the wiring behind your walls, ask these ten questions. The answers will tell you everything you need to know.

1. Are You Licensed in This State and Municipality?

Electrical licensing requirements vary by state, and many cities layer on additional requirements. A master electrician's license in one state means nothing in another. Ask for the license number and verify it with your state's licensing board — most have online lookup tools. In states that don't require licensing (there are a few), check for bonding and certification from recognized programs.

2. Do You Carry Liability Insurance and Workers' Compensation?

General liability insurance protects you if the electrician damages your property. Workers' compensation protects you if a worker gets injured on your property. Ask for a certificate of insurance and confirm coverage is current. Minimum liability coverage should be $500,000, though $1 million is standard. If a contractor doesn't carry workers' comp and someone gets hurt on a ladder in your living room, their medical bills could land on your homeowner's insurance.

3. Will You Pull the Required Permits?

Almost all electrical work beyond swapping a light fixture requires a permit. Panel upgrades, new circuits, rewiring, outdoor installations — all permitted work. If an electrician says "we don't need a permit for this," that's a red flag in most cases. Permitted work gets inspected by a municipal inspector, which is your guarantee that the job meets electrical code. Unpermitted work can create insurance complications and kill a home sale.

4. How Long Have You Been Doing Electrical Work?

Experience matters in electrical work because older homes present wiring challenges that textbooks don't fully cover. Knob-and-tube wiring, aluminum wiring from the 1960s–70s, Federal Pacific panels, backstabbed receptacles — an experienced electrician has seen these and knows how to handle them safely. Five years of field experience is a reasonable minimum for most residential work. For complex jobs like panel upgrades or whole-house rewiring, look for ten-plus years.

5. What's Your Experience With This Specific Type of Work?

Electrical work is broad. An electrician who specializes in new construction may not be the best choice for troubleshooting intermittent faults in a 1940s bungalow. If you need EV charger installation, ask how many they've done. If you're adding a sub-panel to a detached garage, ask about their experience with outdoor runs and trenching. Specificity reveals competence.

6. Can You Provide a Detailed Written Estimate?

A professional estimate should itemize labor, materials, permits, and any subcontractor costs. It should specify the scope of work in plain language: what's included, what's excluded, and what happens if they encounter unexpected conditions (like discovering aluminum wiring behind a wall). Verbal quotes aren't worth the air they're spoken into. Get it in writing, and make sure the estimate has an expiration date.

7. What's Your Timeline for Completion?

A panel upgrade takes a day. A whole-house rewire takes a week or more. Whatever your project, get a realistic timeline with milestones. Ask what could cause delays — permit approval wait times, back-ordered materials, inspection scheduling. The electrician who gives you a thoughtful answer about potential delays is more trustworthy than the one who promises everything will go perfectly.

8. Do You Offer a Warranty on Your Work?

Reputable electricians warranty their labor for at least one year. Some offer two to five years. This is separate from manufacturer warranties on materials like panels, breakers, and fixtures. Ask what the warranty covers, what voids it, and how warranty service requests are handled. Get the warranty terms in writing as part of your contract.

9. Can You Provide References From Recent Similar Projects?

Ask for three references from the past six months for similar scope projects. Then actually call them. Ask the references whether the electrician showed up on time, communicated well, stayed within budget, cleaned up after the work, and whether they'd hire them again. Online reviews supplement references but don't replace them — you want to talk to someone who had a similar job done in a similar type of home.

10. How Do You Handle Change Orders and Unexpected Issues?

Electrical work frequently reveals surprises behind walls. The question isn't whether something unexpected will come up — it's how the electrician handles it. A good answer sounds like: "I stop work, show you what I found, explain the options and costs, and get your written approval before proceeding." A bad answer is vague or implies they'll just handle it and adjust the bill.

The One Bonus Question

Ask this after they've answered everything else: "What questions should I be asking that I haven't?" A knowledgeable, honest electrician will often point out considerations specific to your home or project that you wouldn't have known to ask about. That kind of proactive communication is exactly what you want in someone working on your electrical system.
