General Wiring, Panels & Repairs
Your home’s electrical system powers everything — your lights, your appliances, your comfort, and your safety. When it comes to electrical panel upgrade New Hampshire & something isn’t working right, you need an electrician you can actually trust to get it done properly.
At Finlayson Electric, we don’t cut corners. We show up on time, assess the problem honestly, explain exactly what needs to be done and why, and get to work. Every job — big or small — gets the same level of attention and care.
What's Included
Everything Your Home's Electrical System Needs.
Panel Upgrades & Replacements
An outdated or undersized panel is one of the most common electrical problems in older homes — and one of the most important to address. We install modern panels that meet today's code requirements and handle the demands of contemporary living.
Electrical Rewiring
Whether you're renovating an older home or addressing years of patchwork wiring, we handle full and partial rewires cleanly and correctly — minimizing disruption while bringing everything up to current standards.
Circuit Additions
Adding a home office, finishing a basement, installing a new appliance? We add dedicated circuits where you need them, done safely and to code.
Troubleshooting & Repairs
Tripping breakers, flickering lights, dead outlets — these aren't just annoyances, they're warning signs. We diagnose the root cause and fix it properly, not just the symptom.
Outlet & Switch Installation
New outlets, USB outlets, GFCI outlets, dimmer switches — we handle all installations and replacements, wherever you need them.
Lighting Installation & Upgrades
Recessed lighting, fixture replacements, under-cabinet lighting — installed cleanly and efficiently, with no mess left behind.
Code Compliance Work
Buying, selling, or renovating a home? We handle the electrical inspections and code compliance work that lenders, insurers, and local municipalities require.
Why It Matters
Outdated wiring, overloaded panels, and DIY electrical work are among the leading causes of house fires in New England. Here’s what’s at stake:

Fire Risk
Overloaded panels and degraded wiring are a leading cause of residential fires. Getting it right protects your home and your family.

Insurance Coverage
Many insurers require up-to-date electrical systems. Outdated wiring can affect your coverage or result in higher premiums.

Modern Demands
EV chargers, smart appliances, and home offices all require more capacity. An undersized system can't keep up — and it shows.

Home Value
Electrical issues flag during inspections and appraisals. Addressing them proactively protects your asking price and speeds up closing.

H.Trustindex verifies that the original source of the review is Google. It was such a pleasure working with Finlayson Electric and specifically the owner Scott. I thought I had a major problem, but thankfully it turned out to be a simple fix. Scott sent one of his team members out immediately and he was able to fix the issue in no time at all! I would highly recommend Finlayson Electric for all your electrical needs. Other family members and friends have used Finlayson Electric and they agree with me 100%!

If you don’t call them, you’re doing yourself a disservice. J BachTrustindex verifies that the original source of the review is Google.

Kerry BolesTrustindex verifies that the original source of the review is Google. Scott was prompt and professional, not only with the jobs but with the estimate as well. I couldn’t have asked for a better electrician to complete the work. Scott and crew added a whole house surge protector, added an outlet in a bedroom and installed a motion sensor light on the garage! Thanks again Scott!!! Alexis WinnellTrustindex verifies that the original source of the review is Google. Scott and his team came out in an emergency when a transformer blew and an entire building lost power! With my being a property manager, it is important that my vendors are knowledgeable, responsive and fair! Scott is all of that! I have and will continue to work with Finlayson Electric on multiple projects as he is my go to electrician! . Lia TaniguchiTrustindex verifies that the original source of the review is Google. Johnni installed an EV charger for me. It was tricky because he had to add it to a jam-packed breaker box, run a line all the way to the other side of the house, and deal with the fact that I had ordered the wrong item. He was patient, knowledgeable, creative about problem-solving, did high-quality work, and was consistently pleasant to deal with even though the job took a couple of unexpected turns. He also ended up taking care of a few other electrical jobs for me while he was there. Brian coordinated the whole thing, was incredibly communicative and responsive, and was on top of everything. Would 100% recommend them and will definitely use them in the future for any electrical work I need! Makenzie O’LearyTrustindex verifies that the original source of the review is Google. I hired Finlayson Inc to install a massive ceiling fan in a cupola with very high ceilings. The owner, Scott showed up when he said he would, did a great job, and made quick work of the install. I’m extremely satisfied with the way the it came out. He was punctual, professional, and very reasonably priced. While he was there, he inspected my breaker panel and made recommendations on a future panel upgrade, which I will be sure to hire Scott for my future electrician needs, and highly recommend him to anyone needing residential electrical work.Google rating score: 5.0 of 5, based on 26 reviews
