Peace of Mind You Can’t Get Anywhere Else!
When it comes to backup power, not all installers are created equal. As a certified Generac dealer, we’re trained directly by the manufacturer, giving you access to factory-backed installation standards, faster service, and exclusive promotions you won’t find with non-dealer contractors.
Right now, we’re offering a free upgrade to the industry’s best protection—a full 10-year extended Generac warranty at no additional cost. That’s a decade of coverage from the manufacturer, plus our own lifetime craftsmanship guarantee for ultimate peace of mind.
From the first call to final inspection, we’re committed to delivering a smoother, more professional experience—and standing behind our work long after your generator is up and running.
We install and service Generac generators for homeowners across Dover, Portsmouth, Rochester, Somersworth, and the NH Seacoast, as well as Wolfeboro, Wakefield, and other communities where power outages are a regular concern.

What areas do you serve for generator installation?
We serve homeowners across the NH Seacoast including Dover, Portsmouth, Rochester, Somersworth, Durham, Exeter, Hampton, as well as Wolfeboro, Wakefield, and surrounding communities.
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 flexible financing through Wisetack, including 0% APR for 12 months for qualified customers. On a typical whole-home generator installation, that works out to under $1,000 per month with zero interest. Longer terms up to 60 months are also available for customers who prefer lower monthly payments. We also offer Klarna for shorter-term installment options. Ask about financing when you call or fill out the form and we will walk you through what works best for your project.
Don't Let Upfront Cost Stand Between You and Peace of Mind
A whole-home generator is one of the most valuable investments you can make in your home. We want to make sure cost is never the reason you go without backup power.
Through our financing partners, we offer flexible payment options designed to fit your budget:
- 0% APR for 12 months through Wisetack for qualified customers. On a $12,000 generator installation, that’s $1,000 per month with zero interest.
- Flexible terms up to 60 months for customers who prefer lower monthly payments. Rates vary based on credit and loan terms.
- Klarna is available for customers who prefer a buy-now-pay-later approach with short-term installment options.
