 Trustindex verifies that the original source of the review is Google. Awesome local company!!! Arrived when they said they would. Troy was able to give us a free estimate (which was WAY less than another company estimated) and then complete the work the same day!! Very friendly people. Also, Troy spotted a few minor issues that could become bigger problems and gave us a heads up. No hassle, straight forward dealings with Loyal Lab!! Would definitely recommend them to anyone!

 Trustindex verifies that the original source of the review is Google. Eric and Clay are a great team and very easy to work with. Eric did a great job lifting my generator onto a new pad. I was shocked at how quickly he did the job by himself. Signed up for monitoring for my piece of mind and am confident that the machine’s in good hands. Very happy I made the switch from the “big guys”. You should, too!

 Trustindex verifies that the original source of the review is Google. My experience with Loyal Lab was exceptional. After having a bad experience with a previous company, it was such a pleasure to deal with a professional.  Clay was pleasant, knowledgeable and above fair with pricing with my Generac generator maintenance.  I would use them for all my electrical needs. Thank you.

Certified Installation, Backed for 10 Years

Generator installs aren’t a one-and-done product. The way the system is sized, wired, and tied into your home determines whether it actually works when you need it. We’re factory-trained and certified, which means every install is done to manufacturer spec and your warranty stays intact.

Every standby generator we install comes with a full 10-year extended warranty at no extra cost, plus our own lifetime craftsmanship guarantee on the electrical work. That’s a decade of factory coverage on the unit and a lifetime of accountability on the install, from a locally owned team you can actually reach.

We don’t disappear after the install. Warranty service, annual maintenance, and repairs all run through the same local team that put the generator in. Most generator companies hand off to a third party for ongoing service. We don’t.

Generators Starting Under $200/Month

A whole-home generator typically runs $10,000 to $15,000+ installed. Use the calculator below to see what monthly payments look like for your install. 0% APR for 12 months available for qualified customers through Wisetack.

Pre-qualifying takes about a minute and won’t affect your credit. Ask about financing when you request your quote.

What areas do you serve for generator installation?

We install generators across the NH Seacoast, including Dover, Portsmouth, Rochester, Somersworth, and surrounding towns. We also serve the Lakes Region including Wolfeboro, Wakefield, Alton, and Ossipee, and we cover Southern Maine including Berwick, South Berwick, Eliot, Kittery, York, and Ogunquit. We hold electrician licenses in both New Hampshire (Master #13956) and Maine (#MS60021263), so we can install legally on both sides of the border.

How much does a whole-home generator cost?

Generator pricing depends on the size of your home and your power needs. We provide free consultations to help you determine the right system and give you clear, upfront pricing before any work begins.

How long does generator installation take?

The physical installation typically takes 1-2 days. However, the overall process involves coordinating with your utility company, gas provider, and local inspectors, which can extend the timeline to about a week from start to finish. We manage all of that coordination for you.

What size generator do I need for my home?

That depends on what you want to power during an outage. We do a load calculation during your consultation to determine the right size. Options range from partial-home coverage to whole-home systems that power everything automatically.

Do you offer generator maintenance?

Yes. Regular maintenance keeps your generator ready when you need it. We offer annual service plans as well as our Generator Watchdog monitoring program for 24/7 peace of mind.

What is the difference between a portable generator and a standby generator?

A portable generator requires manual setup and connects through an interlock kit or transfer switch. A standby generator is permanently installed and turns on automatically when the power goes out. No action needed on your part.

Are you an authorized Generac dealer?

Yes. Loyal Lab Electric & Generators is a factory-certified Generac dealer. That means factory-trained installation, access to dealer-only pricing and promotions, and a full 10-year extended Generac warranty on every install. We’re also fully licensed and insured electricians, so your entire installation from the generator to the electrical panel is handled by one qualified team.

Do you offer free estimates?

Yes, we provide free quotes on all residential electrical work. Call us or fill out the form above and we’ll get back to you within 24 hours.

Are you a local company or a franchise?

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.

Do you offer financing?

Yes. We offer financing through Wisetack and Klarna, with options ranging from short-term 0% interest to longer terms with lower monthly payments.
