Generators Installation in New Hampshire

Full Service

The capability to complete any home electrical project!

At Spark, we can help upgrade newer homes, and update older homes. The average home electrical system in our area has 1940s – 1980s era wiring. The demand for electricity has increased significantly compared to the electrical requirements of our homes in the 40s and 50s. It’s important to hire electricians that are familiar with home wiring, and understand how residential structures are built in our area. We work on homes every day. Spark electricians are well versed in local town and city requirements and respected by local code enforcement.

What Our Clients Say

Spark was recommended to us by the owners of Princess Jewelers in Derry. Adam came to our home yesterday. He was knowledgeable, professional, friendly, and very informative. He spent 5+ hours taking care of several projects, and gave us all the options (including the money-saving ones) we needed to make intelligent decisions. We're very happy with the quality of Adam's work and we're looking forward to his return next week when he'll take care of the last 3 tasks on our list. Spark and Adam are very highly recommended indeed.

Evan came out today and repaired both doorbells for our duplex. One of them was very complicated with short wires and he took the time to think outside the box and come up with a solution to make it work so we didn’t have to have holes and repairs done after. He was professional, friendly, patient, and a pleasure to work with. Bonus: he liked my dogs! I will definitely be using Spark Electrician in the future and will be recommending them as well. Thank you Evan!!

Adam did excellent work both times he was at our property. He replaced a fan and a chandelier. Both jobs required a little bit of extra work, and expertise, but Adam didn't even flinch. He executed everything with a smile. Being a new guy at the company, he certainly has customer service on lock down! Heidi at front desk was personable and kept me up to date with appointments and times. Will use again and again. Thanks Adam and Spark!

Kris Gibson

The Spark team of Adam and Alex showed up right on time to repair a light post for me. They were both knowledgeable, thorough and got the job and the inspection done quickly. They were very careful not to track mud into the house (it was an outside job in the snow) and could not have been more pleasant to have at my home. I thoroughly recommend Adam and Alex and Spark.
