Many homes in Marshfield and the surrounding towns were wired long before EV chargers, heat pumps, and central air were common, and coastal storms can leave neighborhoods without power for extended periods. Our services cover both everyday needs and the larger upgrades older homes often require.

Marshfield Electric is a small, local business, and most of our new customers come to us through referrals from neighbors, friends, and past clients. That keeps our standard simple: show up when we say we will, explain the work in plain terms, and treat your home the way we would want ours treated.
We have completed hundreds of residential jobs across the South Shore, from single outlet repairs to panel upgrades, generator installations, EV charger hookups, and whole-home rewiring. In Massachusetts, a licensed electrician must pull the permit for most electrical work, so we handle permits and inspections as part of the job instead of leaving them to you. You can see examples of recent work in our project gallery.
In November 2025, Greet Magazine featured Marshfield Electric as a trusted local service professional.
Rob answered my call at 7pm when my tenant told me they lost heat. He quickly figured out that it was a bad thermostat and had it up and running within an hour. Prices were very reasonable.
Arrived when he said he would. My new recessed lights look awesome. Thanks Rob! You’re my new electrician.
Fixed a bunch of electrical issues I have been dealing with for years. He was very good at explaining things to me and prices were good. Recommend.
They are a great company. Very friendly and reasonably priced
Came right on time. Very professional demeanor. Very neat work. We are very pleased.
He did a great job on my new kitchen and mudroom. Very good with communication and showing up. Love the lights! THANK YOU!
Robert was very polite and fixed a problem that the last two electricians couldn’t fix. Highly Recommend

Yes. Marshfield Electric offers 24/7 emergency electrical service across the South Shore. Call (781) 566-0306 any time if you notice sparking, a breaker that will not reset, or a sudden loss of power. If you smell burning or see smoke, shut off power at the panel if it is safe to do so and call 911 first.
The cost depends on the size of the job. Small tasks like replacing a GFCI outlet or a breaker take less time and material, while panel upgrades, service upgrades, and EV charger installations involve more labor, parts, and permitting. We provide a free, upfront estimate before any work begins, so you know the price before you commit.
Not always, but it is worth checking. Many older homes in the area still have 60 or 100 amp service, which can struggle to support central air, heat pumps, or an EV charger. Warning signs include frequently tripping breakers, a warm panel cover, and flickering lights. A home electrical inspection can tell you whether an upgrade makes sense.
The safest option is a generator interlock kit installed on your panel by a licensed electrician. An interlock lets you power selected circuits from a portable generator while blocking power from flowing back into utility lines, which protects line workers and your equipment. Never run a generator indoors or in an attached garage, and never plug it into a wall outlet.
If something in your home is not working the way it should, or you are planning a project like a panel upgrade, EV charger, or generator hookup, the first step is a conversation. Tell us what is going on, and we will explain your options in plain terms and give you a clear estimate before any work begins.
