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.

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.

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.
