Questions to Ask an Electrician Before You Hire One

Electrical work is the part of a renovation you cannot judge by looking at it. You can see crooked tile. You cannot see an undersized wire in a wall, a loose splice in a ceiling box, or a missing breaker. The only protection is hiring well.

This guide is an interview script. It gives you the questions to ask, what good answers sound like, and what should make you pause. It is written for homeowners, co-op shareholders and small landlords in New York City, Long Island and nearby New Jersey, but the logic applies anywhere.

1. Before You Call: Know What You Need

Good answers depend on a good question. Before you interview anyone, write down the scope in plain language.

• Repair or upgrade? A tripping breaker, a dead outlet and a flickering light are repairs. A new kitchen, a basement or an EV charger is a project.
• Where is the work? Which rooms, floors and panels are involved?
• What is the building? A pre-war walk-up, a co-op, a high-rise condo and a detached house have different rules and access.
• What else is happening? If walls will open for tile, plumbing or a new layout, electrical should be planned with those trades, not before or after.
• What is the deadline? Closing, move-in or a rental start date changes how you sequence work.

Then take photos of the panel with the door open, any labels, and the rooms involved. An electrician who sees that picture can ask better questions and give a better first answer.

2. License and Registration Questions

Question 1: "What is your license number, and which agency issued it?" In New York City, electrical work is generally performed under a licensed master electrician, and the licensing system is run by the city. Long Island counties require home improvement contractor licensing through county consumer affairs, and New Jersey requires contractor registration with the state. Verify with the issuing agency, not with the electrician.

Question 2: "Is the license in your name or your company's?" Many firms operate under a licensed principal. Make sure the name on the license, the contract and the insurance certificate match.

Question 3: "Is your home improvement contractor license current?" For residential remodeling in NYC, the Department of Consumer and Worker Protection publishes the license requirements for home improvement contractors. If the person is not licensed or does not know what you mean, that is your answer.

Question 4: "Who will actually be in my home?" Ask whether the employees who show up are on payroll or subcontracted, and whether they are supervised by a licensed electrician. We cover this more below.

3. Insurance and Bonding

Insurance protects you when something goes wrong. Ask for these items in writing, and keep copies.

1. General liability coverage. It pays for damage to your property.
2. Workers' compensation. It covers injuries to workers. Without it, a hurt worker may look to the homeowner.
3. Certificate of insurance (COI). Many co-ops and condos require one naming the building and management company. Our contractor hiring checklist explains what to ask for.
4. Bonding. A bond is not the same as insurance. It can provide a remedy if a contractor fails to complete work or to pay suppliers. Ask whether one exists and what it covers.

Do not accept a verbal "we're insured." Ask for the certificate and call the insurer or broker listed to confirm it is active.

4. Permits, Inspections and Code

Question 5: "Does this job need a permit, and who pulls it?" In NYC, most electrical work beyond simple device replacement requires a permit and inspection through the Department of Buildings process, and the licensed electrician files for it. The DOB's guide to obtaining a permit explains the system. Outside the city, your town, village or municipality issues permits; in New Jersey, the local construction office does so under the Uniform Construction Code.

Question 6: "Who schedules the inspection, and what happens if it fails?" A good electrician says: "I schedule it, I fix what the inspector finds, and I give you the sign-off." A poor one says: "We don't need that."

Question 7: "Which code applies?" The electrical code is updated periodically and adopted locally, so ask which edition applies to your job and what protections it requires in kitchens, baths, basements and exterior locations. Protective devices such as ground-fault and arc-fault breakers are common requirements in many areas.

Question 8: "Will you check my panel capacity?" Adding a kitchen, an air conditioner or a vehicle charger can exceed a panel's capacity. A load calculation should come before the quote, not after the surprise.

Our permit guide explains how to tell what needs filing in New York City.

5. Experience and References

Question 9: "Have you done work like this in buildings like mine?" A rewire in a rowhouse differs from a fixture swap in a doorman building. Ask about co-op alteration agreements, freight elevators and work-hour limits if relevant.

Question 10: "Can I speak to two recent customers?" Call them. Ask whether the electrician showed up on time, protected floors, stayed within the quote, passed inspection and fixed problems quickly.

Question 11: "Do you have photos of recent work?" Neat panels, labeled circuits and clean wire runs are signs of care. If they can show pictures of panel work, you learn how they think.

Question 12: "What training do your workers have?" Ask about apprenticeship, continuing education and any manufacturer training for specialized equipment such as smart-home systems or chargers.

6. Scope, Price and Payment

Question 13: "Can I get a written, itemized quote?" A good one lists the work area by area, the number of circuits and outlets, fixtures and who supplies them, permit and inspection costs, and clean-up. It states what is not included.

Question 14: "How do you handle surprises behind the wall?" Old wiring, junction boxes buried in plaster and undocumented splices are common in older buildings. The answer should be: "We stop, photograph, price the fix in writing and wait for your approval."

Question 15: "What is the payment schedule?" Reasonable arrangements tie payments to milestones such as rough-in, inspection and completion. Be careful with large cash deposits or payments far ahead of work done. Deposit limits and contract requirements exist for home improvement work, so check with the DCWP or your attorney what applies to you.

Question 16: "Is there a minimum charge or travel fee?" Small jobs often have them. Better to know up front.

Compare quotes using the same list of items, and read our NYC renovation cost guide to see where electrical sits inside a bigger project budget.

7. Subcontractors, Schedule and Cleanup

Question 17: "Do you use subcontractors?" Some jobs do involve specialists, such as low-voltage or fire-alarm technicians. That is fine if the electrician takes responsibility, names them in writing and confirms their insurance.

Question 18: "Who is the point of contact, and how fast do you reply?" Poor communication in the first week predicts poor communication during the job.

Question 19: "What is the schedule, and what could change it?" Typical electrical stages in a renovation are rough-in before walls close, inspection, then finish work after paint and tile. Material lead times, permit review and building access all affect dates.

Question 20: "How will you protect my home?" Look for floor protection, dust control when cutting walls and a daily clean-up routine.

Question 21: "What is your warranty, in writing?" A good electrician states what is covered, for how long and how to request service. Never accept a verbal promise.

9. Neighborhoods and ZIP Codes We Serve

Electrical work depends on the building. Here is what we see in six areas.

• Murray Hill (10016): Mid-rise co-ops and condos, brownstones and walk-ups. Brownstones often carry mixed old and new wiring, and co-ops require board-approved electricians.
• Gowanus (11215, 11217, 11231): New condos, converted industrial lofts and flood-zone considerations. Basement and ground-floor panels may need elevation or protection.
• Whitestone (11357): Detached and semi-detached homes on large lots. Service upgrades for additions, finished basements and chargers are common.
• Stapleton (10304): Victorian houses, Stapleton Heights and new waterfront condos. Older wiring in Victorians often needs careful assessment before renovation.
• Jericho (11753): Colonials and large homes in the Town of Oyster Bay. Permits come through the town, and larger homes have bigger panels and more circuits.
• Fort Lee (07024): High-rise condos and co-ops, where association rules, insurance and elevator reservations come first. New Jersey permits come from the local construction office. See the NJ Consumer Affairs site for contractor registration information.

We serve the rest of NYC, Long Island and northern and central New Jersey as well. If you are re-siding or updating the exterior, our guide to siding for New York homes is worth reading, because exterior lights, meters and outlets must be coordinated with the siding work.
