Gagnon's Electrical Services says it has served southern New Hampshire and northern Massachusetts since 1958 and is in its third generation of family ownership. It describes its work as residential and commercial electrical jobs, including panel upgrades, wiring, lighting, inspections and EV charger installation. Its New Hampshire electrician license, number 8304, and its Massachusetts electrician license, number 1727, are active on the state registries, both held by William R Gagnon. A recent customer said they came very fast after the call and got the breakers fixed right away. A recent customer who had them replace an electrical panel and a bathroom fan said they got there within two days both times. A recent customer said they came on very short notice to replace a broken circuit and remove some wiring; when those wires turned out to power the lighting at the front of the house, they returned the next day and fixed it free of charge. A 2024 customer said Bill and his son installed a Tesla wall connector and called it a clean install. A 2025 customer wrote that Bill and Shawn completed an EV charger installation in their garage. In a 2024 review, an insurance agency said Bill Gagnon picked up the phone at 4 PM on a Sunday after a car accident took down a pole, and he and Shawn worked with Eversource to have power back on by Monday morning, with a new mast and new hookups for 3 units. A 2025 customer was charged $135 for a service call they described as basically a 10-minute information-giving conversation, and said the business only took checks. A 2023 customer said no one showed up on the Thursday they had taken off work, and the visit was moved to Friday. A 2022 customer said the business did not get back to people who used the contact form on its website.
They came very fast after my call, he was able to help with our breakers and got them fixed right away. Would definitely recommend!
I couldn’t be happier with Gagnon’s Electrical Service. From start to finish, the experience was seamless — they came out promptly, got everything done efficiently in a matter of hours, and were an absolute pleasure to work with. Courteous, professional, and genuinely skilled at what they do. Finding Gagnon’s was a real win, and I wouldn’t hesitate to call them again or recommend them to anyone in need of reliable, top-notch electrical work.
I had a wonderful experience with Gagnon Electric. They came to my home on very short notice to replace a broken circuit and remove some wiring behind my house. I later realized that the wires I asked them to remove were actually powering lighting at the front of my house. They returned the next day and fixed the issue free of charge. Their kindness and generosity, especially after my mistake, really stood out. I highly recommend this team!
We have now used Gagnon’s Electrical for two projects, replacing our electrical panel and replacing our bathroom fan. Both times they were prompt, extremely knowledgeable, and no BS. He doesn’t try to oversell you things you do not need and gets the job done quickly and undoubtedly cheaper than most with high overheads. In both instances he was able to get to us within two days. He doesn’t just make sure it gets done, he goes above and beyond to make sure it’s done right. I wish more businesses were the same. If you need work done, you should definitely give them a call!
Mr. Gagnon answered the call and fixed our breaker problem within an hour AFTER hours. Courteous, friendly, and efficient. Thank you!
