If your lights are flickering, your breakers keep tripping, or you need a panel that can keep up with modern electrical demands, Loyal Lab Electric & Generators is the team Portsmouth homeowners trust to get it done right.
We are a locally owned electrical contracting company based in Somersworth, about 15 minutes from downtown Portsmouth. Our licensed master electricians and trained team handle everything from same-day troubleshooting calls to full panel replacements, whole-home generator installations, and EV charger setups. We work on homes throughout Portsmouth, from the historic neighborhoods near Market Square and the South End to the residential areas off Woodbury Avenue, Greenland Road, and around the Portsmouth traffic circle.
Every job comes with upfront pricing, a written scope of work, and a satisfaction guarantee. No surprise charges, no vague estimates. You know what you are paying before we start.
Our team is trained to identify additional safety concerns during every visit. If we spot something that needs attention, we will let you know with clear options and pricing so you can make the right decision for your home.

Portsmouth has some of the oldest houses on the Seacoast, and that creates unique electrical challenges. Many homes in the South End, around Islington Street, and near the waterfront date back to the 1800s and still have original wiring, undersized panels, or knob-and-tube remnants. Even the newer homes off Lafayette Road and in the Greenland border area often need additional capacity for EV chargers, heat pumps, or home additions.
We work in Portsmouth every week and know what to expect when we open a panel in these homes. That experience means faster diagnostics, accurate quotes, and fewer surprises during the job.
Here is what sets us apart:
After hundreds of service calls across the Seacoast, we have seen the same issues come up again and again in Portsmouth homes. If any of these sound familiar, give us a call:
Flickering or dimming lights are one of the most common calls we get from Portsmouth homeowners, especially in older homes near the downtown historic district and along Middle Street. This usually points to loose connections, an overloaded circuit, or an aging panel that cannot keep up with modern demand.
Breakers that trip repeatedly often mean a circuit is overloaded or there is a deeper wiring issue. We trace the problem to its source rather than just resetting the breaker and hoping for the best.
Federal Pacific and Zinsco panels are still in homes throughout Portsmouth. These panels were recalled decades ago because they fail to trip during an overload, creating a serious fire risk. If you have one, replacement is not optional, it is a safety priority.
Insufficient panel capacity is increasingly common as Portsmouth homeowners add EV chargers, heat pumps, and home offices. A 100-amp panel that was fine 30 years ago may not cut it today. We can upgrade you to 200 amps or more to handle current and future demand.
Ungrounded outlets and missing GFCI protection show up in older Portsmouth homes that have never had a full electrical update. These are code violations and genuine safety hazards, especially in kitchens, bathrooms, and garages.
Corrosion and salt air damage is something we see more in Portsmouth than almost anywhere else on the Seacoast. The proximity to the ocean and the Piscataqua River means panels, service entrance cables, and outdoor electrical components take a beating from salt air. We regularly find corroded bus bars, rusted breaker connections, and deteriorated grounding systems in homes near the waterfront and along the coast. If your panel is in a damp basement close to the water, it’s worth having it inspected.
Loyal Lab Electric is not just a company that works in Portsmouth. We actually enjoy spending time there.
Our team celebrated the holidays this year at Vent, the rage room right here in Portsmouth. Our owner Eric and his wife have been coming to downtown Portsmouth for years, walking the waterfront, eating outside at spots like The River House, and taking the Isles of Shoals tour boat. When your team spends their free time in a place, they care about the work they do there.
Portsmouth’s historic downtown district is one of the oldest in the country, and that history is part of what makes it special. It also means electrical work in Portsmouth requires an electrician who understands what they’re walking into. Older homes in the historic district come with unique wiring challenges, tight spaces, plaster walls, and building codes designed to preserve the character of the neighborhood. We respect that and work within those constraints every week.
We are proud members of the Greater Portsmouth Chamber of Commerce and supporters of local dog rescues through our Rusty Fund initiative. For every completed job, we donate $10 to support local rescues, and $100 for every generator installation. The fund is named after Rusty, the loyal yellow lab who inspired our company name and the values we bring to every job.
When you hire Loyal Lab Electric, you are not just getting great electrical work. You are supporting a local business that shows up in Portsmouth because we want to, not just because we have to.
Most service calls in Portsmouth are scheduled same-day or next-day. For emergencies like a panel failure or burning smell, we prioritize getting to you as fast as possible. Portsmouth is only about 15 minutes from our shop in Somersworth, so response times are quick.
Yes. Our shop is in Somersworth and we serve all of Portsmouth and the surrounding area including Kittery, Rye, New Castle, Greenland, Newington, and North Hampton. Portsmouth and the Seacoast are part of our core service area.
We provide upfront pricing so you know the cost before we start. A standard service call and diagnosis starts at a set rate, and any additional work is quoted upfront before we proceed. No hourly surprises.
Yes. Loyal Lab Electric & Generators holds a New Hampshire and Maine Master Electrician license and carries full liability insurance and workers compensation coverage. We also pull all required permits and schedule inspections for every job that requires them.
We offer free estimates for larger projects like panel upgrades, generator installations, and EV charger setups. For service calls and troubleshooting, there is a service call fee but any work required beyond that will be quoted for free before any repairs begin
In most cases, yes. Fuse boxes are outdated technology that cannot safely support modern electrical loads. They also make it difficult to get homeowners insurance at reasonable rates. We can replace your fuse box with a modern breaker panel, typically in one day.
We are an authorized Generac dealer and install Generac whole-home standby generators. We also provide ongoing maintenance and service for Generac generators. Portsmouth and the surrounding area experience enough power outages, especially during winter storms, that a standby generator is one of the best investments you can make.
Most electrical work beyond basic outlet or switch replacement requires a permit in Portsmouth. We handle all permitting and schedule the required inspections with the City of Portsmouth building department so you do not have to.
The Rusty Fund is our charitable initiative supporting local dog rescues, including the Pope Memorial Humane Society in Dover. We donate $10 from every completed job and $100 from every generator installation. It is named after Rusty, the yellow lab who inspired everything Loyal Lab stands for.
