Electrical Panel Upgrades in Dover, Portsmouth & the NH Seacoast

Safe, Professional Panel Replacements and Service Upgrades for Your Home

Dover & Portsmouth's Trusted Team for Panel Upgrades and Service Upgrades

Is your electrical panel keeping up with your home’s demands? Homes across Dover, Portsmouth, and the NH Seacoast were built with 100-amp panels that weren’t designed for today’s electrical loads. Between EV chargers, heat pumps, home offices, and modern appliances, an outdated panel isn’t just inconvenient, it can be a safety hazard.

At Loyal Lab Electric & Generators, we handle panel upgrades and full service upgrades for homeowners throughout the Seacoast. Whether you need a straightforward panel swap or a complete service upgrade including the meter base, service entrance cable, and grounding system, our master electrician and team get it done right, permitted, inspected, and up to code.

If your home has a Federal Pacific, Zinsco, Pushmatic, or Stab-Lok panel, replacement isn’t optional. These panels have well-documented safety defects and should be replaced as soon as possible.

How Do I Know If I Need a Panel Upgrade?

Most homeowners who call us for a panel upgrade in Dover, Portsmouth, and Rochester are dealing with the same symptoms: flickering lights, breakers that trip regularly, or a panel that feels warm to the touch. These are all signs your electrical system is struggling to keep up.

When we upgrade your panel, we don’t just swap the box. A full service upgrade includes:

So many people miss all the signs, that’s why we put together an article to help you identify the most common signs that your panel is ready for an upgrade

If we can upgrade your system without moving the location of your panel, we do, saving you time and money.

If your panel is current but you’re still experiencing wiring issues, that’s a different problem. Visit our electrical troubleshooting and repairs page to learn how we diagnose and fix those issues.

What Are the Benefits of a Panel Upgrade?

A panel upgrade is one of the most impactful improvements you can make to your home’s electrical system. Here’s what it does for homeowners in Dover, Portsmouth, and across the Seacoast:

Safety: Outdated panels with failing breakers, corrosion, or heat damage are a fire risk. A new panel with properly rated breakers protects your home and your family. If you have a recalled brand like Federal Pacific or Zinsco, this alone is reason enough to upgrade.

Capacity: Today’s homes demand more power than they did 20 or 30 years ago. If you’re adding an EV charger, a generator, a heat pump, or a hot tub, your existing panel may not have room. A 200-amp upgrade gives you the capacity to handle modern electrical loads without tripping breakers or overloading circuits.

Functionality: Smart breaker panels can notify you when the power goes out, even when you’re away. A modern panel also gives you cleaner circuit organization, proper AFCI protection for bedrooms, and room to grow as your needs change.

The panel is only one part of your home’s electrical service. We wrote a full breakdown of every component, from the Eversource drop to the grounding rod.

Panel Upgrade and Service Upgrade Services We Provide

How quickly can you get an electrician to my home?

 We typically schedule consultations within 1-2 business days. Most panel upgrades are completed in one day, and full service changes take 1-2 days.

We serve homeowners across the NH Seacoast including Dover, Portsmouth, Rochester, Somersworth, Durham, Newmarket, Exeter, Hampton, and surrounding towns. We also serve parts of southern Maine including Berwick, Kittery, Eliot, and York.

Panel upgrades vary depending on the scope of work, but we provide clear, upfront pricing before any work begins. Call us or fill out the form above for a free quote.

 A panel upgrade replaces your breaker panel with a modern one. A service change upgrades the entire system including the meter base, service entrance cable, grounding, and panel. We’ll assess your home and recommend the right option.

Most residential panel upgrades are completed in one day. A full service change may take 1-2 days depending on the scope of work. 

Yes, your power will need to be disconnected during the panel swap, typically for 4-6 hours. We coordinate with Eversource to schedule the disconnection and reconnection and we always plan to complete everything in the same day so your power is back before evening.

It depends on the scope of work. A straightforward panel swap in the same location may not require a permit in some towns, but a full service upgrade with a new meter base and service entrance cable typically does. We know the permitting requirements for every town we serve across the Seacoast and we’ll let you know upfront whether your project needs one. If it does, we handle the entire process including scheduling the inspection.

Federal Pacific panels have been linked to thousands of house fires due to breakers that fail to trip during an overload. If your home has one, we strongly recommend replacing it. The same applies to Zinsco and Stab-lok panels.

If your breakers trip frequently, your panel is warm to the touch, you smell burning near the panel, you see visible corrosion or rust on the outside, or your home has a Federal Pacific, Zinsco, or Stab-lok panel, it’s time for a replacement. These are signs of a serious safety issue.  Check out our article where we go over other signs you may need a panel upgrade.

Troy came right away and trouble shot our issue with a burned out kitchen light. It turned out to be a bigger job than expected but he remained pleasant and completed the job in a timely manner. I would definitely called them again if I need any electrical work done.

I contacted Loyal Lab about doing all the wiring in my new (detached) garage. They responded very promptly to my initial request for a quote. I met with Clay, we went over the entire scope of the job, discussed many of the details, he took notes, returned to his office, and provided a quotation that same day. I thought the quoted price was reasonable and acceptable. (I did not get a second quote, but rather based my decision on previous discussions with two other electrical contractors.) Clay's estimate of when the job would start and the duration was much better than what I had heard from other contractors in the area. The job took about half a day longer than originally expected - that was not a problem and it was reasonable. The crew that performed the work showed up at a decent hour each day, worked a full day, cleaned up at the end of each day, and they conducted themselves professionally. The crew contacted me to quickly resolve a few questions during the installation. The installation went pretty smoothly. Electrical inspections went very well. The quality of work was very good, in my opinion. All in all, my experience with Loyal Lab was much better than any other contractors (electrical or other trades) on the construction of building my new garage. The quote was sufficiently detailed, the price was acceptable, the schedule was excellent, and the results were very good. I'm happy. Yes, I would recommend talking with them for your next electrical project. [Note that Loyal Lab did not install the "service" (meter or breaker box). That was done by another electrical contractor that I would not hire to do what Loyal Lab did.]

I had several small electrical jobs that needed to be done. They were quick to respond to my initial request, came same day to issue a quote, and one week later completed the job. They know their job and I love the results.

Definitely on the expensive side, but Troy and Ben were right on time, very friendly, and took care of our light switches/ceiling fans quickly. They were so sweet to our son who had lots of questions and they even left him some stickers!!

What a difference going with a locally owned company. I had the Mr. Electric, Heritage, etc experience and wanted to find someone local who wasn't going to upsell, try to talk me into a service contract or try to rip me off. Troy was superb, arrived right on time and he was able to diagnose the issue in short order and made sure everything was working before leaving. The price was very reasonable and he even explained that all his work came with a one year warranty. Highly recommend and would definitely use them again.

Justin and his partner(whose name I forgot, I apologize) were outstanding! They understood the work I was looking to have done, gave me a very reasonable quote, and were able to finish the project the same day. In addition, they willingly changed a very high up lightbulb in my garage for no extra charge. I will definitely be using their services in the future for any other electrical needs!

Troy was exceptional today on his service call to my house. He walked me through everything as he worked, explaining what he was doing and why, giving me a real peace of mind - the insight was genuinely helpful for any future projects, as well. Quality work, clear communication and a friendly, patient approach throughout. I highly recommend Loyal Lab and we'll be calling them again for future project.
