About Northline Electric
A licensed, bonded electrical contractor based in Freehold, serving homeowners, businesses, and general contractors across Monmouth County and Central New Jersey since 2014.
Northline Electric is a licensed New Jersey electrical company built on one idea: do the job right the first time, and explain it in plain English. For 12+ years we've wired homes, storefronts, and job sites across Monmouth and Middlesex County — panel and service upgrades, EV chargers, standby generators, rewiring, lighting, and low-voltage — always permitted, inspected, and done to code.
We work with homeowners, business owners, and general contractors alike. Whatever the job, you get clear pricing up front — a written estimate on the bigger work and no surprise charges on the small stuff — a clean and respectful crew, and a team that pulls the permit and coordinates the inspection so you don't have to.
Meet the owner.
Marcus Whelan leads Northline's team of licensed electricians. He's hands-on, accountable, and known for showing up when he says he will — the kind of contractor who keeps you posted the whole way through and stands behind the work.

What homeowners say
“Marcus came out the same day to sort out a panel that kept tripping. He walked me through exactly what was wrong, gave me the price before touching anything, and had it fixed cleanly in an afternoon. No mess, no upsell. Northline is the only electrician I’ll call now.”
“Booked a Level 2 charger install. They handled the load calc, the permit, and the inspection without me chasing anything. Showed up when they said, cleaned up after, and the work looks factory-neat.”
“We had knob-and-tube in half the house. Northline gave us a straight plan, did it in stages so we weren’t without power, and patched everything back up. Honest crew and fair on price.”
“Standby generator hookup for the whole house. Professional from the quote to the final inspection. Explained the transfer switch so I actually understood it.”
“Great work on our kitchen remodel wiring and recessed lighting. Scheduling took a couple tries to line up, but once they were here the work was excellent and they stood behind it.”
