We're Local and We Stay Local

Gagnon's Electrical Services is based in Nashua, NH, not a regional call center dispatching whoever is closest. When you call us, you're talking to someone who knows this area, knows the housing stock, and has a reputation in this community worth protecting. We work in Nashua and the surrounding towns because this is our backyard.

Straight Talk on Every Estimate

We give you a clear number before any work begins. No vague ranges, no low bids that climb once we're on site. If something unexpected comes up mid-job, we stop, explain what we found, and give you the updated picture before we touch anything else. You stay in control of your project from start to finish.

Licensed, Insured, and Permit-Ready

Every job Gagnon's Electrical Services takes on meets New Hampshire electrical code. We pull permits when the work requires them and don't cut corners to save time on our end. That protects you when it comes time to sell your home, file an insurance claim, or pass an inspection. No shortcuts. No exceptions. No excuses.

We Respect Your Home

We clean up when we're done. Wire clippings off the floor, tools out of the hallway, work area left the way we found it. We wear shoe covers in finished spaces and we don't leave holes in walls that weren't part of the plan. Your home gets treated the way we'd want our own treated.

We Work Around Your Schedule

Electrical work shouldn't mean taking a full day off. Gagnon's Electrical Services works to accommodate homeowners who have jobs, kids, and limited availability. We give you a clear arrival window, we show up in it, and we communicate promptly if anything on our end changes.

I was shocked (pun intended) at how quickly Bill responded to my call. They had my problem solved in no time and even made a quick change to a switch in another room while they were here. Great service and a very fair price! I highly recommend Gagnon's Electrical Service - they will be the first ones I call for any future needs!

We had a sudden loss of power to multiple outlets throughout our home, Bill and Shawn were able to make it here the same day I called; they found the problem and were in and out in about an hour. I would highly recommend them. Honest and fair. They don’t make them like these guys anymore. Thank you for what you do, Gagnon Electric. :)

The MacIntyre Family has used Gagnon's (Bill & son) for many years for various home support. They are always Pros, do good work & at a fair price. I have had my service upgraded, alarms done, doorbells, outside link for home generator, you name it...& I always can rely on their great support. They are the best in the Nashua area.
