We Find It and Fix It

Something not right with your electrical system? Flickering lights, tripping breakers, outlets that stopped working, or a burning smell coming from your panel are all signs that something needs attention now, not later.

At Loyal Lab Electric & Generators, we handle electrical troubleshooting and repairs across Dover, Portsmouth, Rochester, Somersworth, and the entire NH Seacoast. Our master electrician and team of licensed techs have seen it all, from 100-year-old knob and tube wiring in Portsmouth colonials to overloaded panels in newer Dover developments. We show up, diagnose the problem, explain what we find in plain English, and fix it right the first time.

Every troubleshooting visit starts with a thorough diagnostic evaluation of your electrical system so we know exactly what we’re dealing with before any work begins. No guessing, no unnecessary upsells, just honest answers and quality repairs.

Common Electrical Problems Homeowners Call Us About

Most of our troubleshooting calls in Dover, Portsmouth, and Rochester start the same way: something changed and it doesn’t feel right. Maybe half your house lost power. Maybe a breaker keeps tripping every time you run the microwave. Maybe you noticed a faint burning smell near your panel and you’re not sure if it’s serious (it usually is).

Here are the problems our customers call us about most often:

Tripping Breakers: A breaker that trips once is doing its job. A breaker that trips repeatedly is telling you something is wrong. It could be an overloaded circuit, a short in the wiring, or a failing breaker itself. We trace the issue to the source and fix it so it stays fixed.

Flickering or Dimming Lights: This is one of the most common calls we get across the Seacoast. Sometimes it’s a loose connection. Sometimes it’s a sign of a bigger issue like a failing neutral or an overloaded circuit. Either way, it’s not something to ignore.

Dead Outlets or Switches: An outlet that stops working could be a tripped GFCI somewhere else in the circuit, a loose wire, or a failed device. We test and trace the circuit to find the actual cause.

Partial Power Loss: When half your house loses power but the other half works fine, it’s usually a lost leg of power at the panel or utility connection. This one needs professional diagnosis quickly.

Burning Smell Near Panel or Outlets: If you smell something burning near your electrical panel, an outlet, or a switch, call us immediately. This can indicate a loose connection generating heat, a failing breaker, or damaged wiring. Don’t wait on this one.

Frequently Tripping GFCI Outlets: GFCI outlets that won’t stay reset often point to a ground fault somewhere downstream in the circuit. We trace the fault and repair or replace whatever is causing it.

Why Electrical Troubleshooting Needs a Licensed Electrician

Electrical problems are rarely as simple as they look on the surface. A flickering light could be a loose bulb or it could be a failing connection inside your wall that’s generating heat every time it arcs. The difference between those two scenarios is the difference between a five-minute fix and a potential fire.

Our team is led by a NH Master Electrician with 20 years of experience in the Seacoast. We have the tools, training, and diagnostic experience to tell the difference between a nuisance issue and a safety hazard.

Every repair we do meets current NH electrical code. We pull permits when required, we explain what we find before we start any work, and we stand behind everything we do. Whether the job takes 30 minutes or half a day, you’ll know exactly what was wrong and exactly what we did to fix it.

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.

Frequently Asked Questions About Electrical Repairs

My breaker keeps tripping. Is it dangerous?

A repeatedly tripping breaker is your electrical system telling you something is wrong. It could be an overloaded circuit, a short in the wiring, or a failing breaker. It’s not dangerous as long as the breaker is doing its job and tripping, but the underlying cause needs to be diagnosed and fixed by a licensed electrician before it becomes a bigger problem.

We serve the entire NH Seacoast including Dover, Portsmouth, Rochester, Somersworth, Durham, Newmarket, Exeter, Hampton, Rye, Greenland, and surrounding communities. Our shop is in Somersworth and most service calls are within 20-30 minutes.

This usually means you’ve lost one leg of your electrical service, either at the panel, the meter, or the utility connection. It’s not something you can fix yourself and it needs professional diagnosis. Call us and we can usually get there same day or next day.

Yes. Loyal Lab Electric & Generators is fully licensed and insured in New Hampshire and Maine. Our owner is a master electrician with over 20 years of experience.

For most service calls in Dover, Portsmouth, Rochester, and the Seacoast, we can typically schedule same-day or next-day appointments. For emergencies like burning smells or sparking, we prioritize getting there as fast as possible.

Loyal Lab Electric & Generators is 100% locally owned and operated right here in Somersworth, NH. We’ve been serving the Seacoast since 2018 and have no affiliation with any franchise or corporate entity. When you call us, you’re supporting a local business and working directly with our team.

A burning smell near your panel is serious. It often means a loose connection is generating heat or a breaker is failing. Turn off the main breaker if you can do so safely and call us immediately. This is one situation where waiting can lead to a fire.

For anything beyond changing a light bulb or resetting a tripped breaker, we strongly recommend calling a licensed electrician. Electrical work involves hidden hazards like live wires behind walls, shared circuits that affect other parts of your home, and code requirements that exist for your safety. The risk of shock, fire, or creating a bigger problem isn’t worth saving a few dollars.

Every situation is different, which is why we provide upfront pricing after our initial diagnostic evaluation. We never charge by the hour and we always explain what we find and what it will cost before we start any repair work. No surprises.
