Diamond Electrical has 77 HomeAdvisor ratings averaging 4.8 stars, and its HomeAdvisor profile now narrows the work to one job. There the company says it is not currently offering smaller electrical services such as outlets and fixtures, and only services electrical panel upgrades within the home. Its New Hampshire electrician licence, number 181C, held by Diamond Electrical Contractors Corp, is expired on the state registry, which lists it as lapsed. A recent Google customer said Mark came out on a Sunday morning to help find out why only half the house had power, and was very detailed when explaining everything. A 2025 customer thanked Mark for adding a circuit breaker for a water tank. A 2025 reviewer said the crew arrived on time and communicated clearly during an electrical service upgrade. A 2020 customer said Mark came out the same day to fix a main breaker that kept popping, and called the prices very reasonable. A 2020 reviewer said Mark installed a generator and pointed out some other issues that needed attention. A 2019 reviewer described the replacement of an old 60 amp main panel with a new 100 amp panel. A 2017 customer said Mark handled the permit and Eversource details and worked around their schedule to finish quickly. A 2021 customer took off half a star because some things were not addressed: the basement was wired with a 15 amp breaker that has failed under load, and instead of being replaced with a 20 amp it was left as is.
Awesome Job and fast
Mark came out on a Sunday morning to help with finding out why only half the house had power. He was very professional and very detailed when explaining everything. He had also brought along his passenger princess Ruby, I believe that's her name. She was very well behaved so much so that our own pups didn't even know that she was there.
If you are looking for the Best of the Best hire Mark!! Professional, Quality and Amazing!! Thank you for adding a Circuit Breaker for my Water Tank!!
I am writing to express my sincere appreciation for the outstanding work performed by Diamond Electric during a recent electrical service upgrade at our property. From start to finish, the entire crew demonstrated professionalism, punctuality, and exceptional craftsmanship. They arrived on time, communicated clearly throughout the process, and completed the work efficiently and safely. What stood out most was their attention to detail—even the smallest aspects of the job were handled with care and precision. It’s not often that you come across contractors who combine technical expertise with such a strong commitment to quality and customer satisfaction. I would not hesitate to work with them again, and I highly recommend their services to anyone in need of electrical work.
I would recommend them. My service was done in record time. The electrician was very polite and friendly.
