Custom Electric & Communications is a Merrimack, New Hampshire electrician, and a 2024 customer whose outlet got hit, shorted and caused a small burn said the company told them someone would be over in a few hours. That 2024 customer said Dylan looked things over, tested the lines, made the repairs and tested things again. The company describes itself as an electrical contractor since 1985, working from Merrimack across New England on residential, commercial, industrial, institutional and government jobs. A 2024 customer said the company replaced the original 1980s two-wire thermostat lines on the first and second floors with five-wire lines and ran a Cat-6 cable from a basement patch panel to a second-floor bedroom without opening the drywall. That 2024 customer named Mark and Brian and said they vacuumed and cleaned up after themselves. In a 2024 review, a customer wrote that a job meant coordinating with Eversource to add a new breaker box for 50A more power, and Walter, Patrick and Chris got the job done in less time than expected. A 2023 customer said another local electrician would not dig or troubleshoot a break in the ground wire to an exterior light, and Walter isolated the break and upgraded the line with a junction box. A 2023 reviewer with lights going on and off said the company came out that afternoon, found a bad breaker by the meter and replaced it. A 2022 reviewer who manages maintenance for two nursing homes and two assisted living facilities called the company a preferred source for electrical projects, and said those buildings sometimes need electrical support on very short notice or long into the night. Its New Hampshire electrician license, number 63C, in the name of Custom Electric & Communications LLC, is expired on the state registry, which records it as "Lapsed". The Better Business Bureau gives the company an A+ grade and lists license number 2818 M. A recent Google reviewer wrote of using the company for several years on projects big and small at their homes, and called it reasonably priced.

We have used Custom Electric over a several years on a multitude of projects from big to small at our homes. We have always been impressed with the quality of their work. Very personable and always reasonably priced.
As a property manager, I have worked with many vendors over the years, and this electric and communications company stands out as one of the best. I have relied on them for more years than I can count, and they consistently deliver exceptional work with truly top-notch customer service. Walter, in particular, NEVER disappoints. His attention to detail, professionalism, and impeccable workmanship give me complete confidence every time he is on the job. It is rare to find a company this dependable, and I highly recommend them to anyone looking for quality, reliability and outstanding service.
We had some issues at our house we needed help with. Fans with no switches, outlets that didn't work, and a garage with only one outlet. Walter and his apprentice came over and solved all of our problems. Now everything works and I have an outlet right where I need it in the garage. He was a true professional, and even kind to over-eager dog. :) Thank you for all of your help! I'd hire them again without question.
We had some issues with our electrical outlets downstairs and the customer electrical team was able to get us on the schedule very quickly. The electrician was super friendly and was able to switch out several outlets very quickly. Great service and very fair prices.
I have been working directly with Custom Electric since starting my Property Management career in New Hampshire. They have remained efficient and reliable over each project. The property that they service on my portfolio definitely has its quirks; however, I can rely on Custom to handle each issue with care from their apprentices to their seasoned electricians. They service our alarm system, exterior and interior lights, as well has our electrical panels.
