John P. Tierney III

John returned my call in an hour. Got back to me later that day with a price and completed the work two days later. Cleaned up after himself. This guy is as perfect as can be. If they had ten stars I would give it to him. On top of all that, he is a real nice guy. I already recommended him to a neighbor. Thanks John !

John was extremely knowledgeable and efficient. He arrived on time, got right to work, was willing to answer any questions and even did an additional request during the same visit. He tried his best to be non-invasive and to clean up after himself and his workers and he was friendly throughout the project time. I would definitely recommend him.

I hired John twice to install light fixtures in my house. He was quick to respond and quick to come, and I'm very satisfied with John's work. In one place, I needed an old light fixture to be removed and the new to be installed in a different place. And there was a sizable hole in the wall from the old fixture. John also patched the hole, so, all what I had to do after his work is to paint the wall, which I was planning to do after the fixture installation. In fact, I'm planning to hire John again shortly for another job.

He surpassed Gagnon Electric on knowhow & best solution to an ongoing Living Room Circuit that continually tripped. He checked to see that we were compliant with surgeprotection box w/green lights working properly. It was sufficient to handle lightening strikes & correctly installed. He was thorough in testing amps & supplied us with a Arch Grounding new socket that works very well with air conditioner's ground plug. Very satisfied with his work & attention to detail. Noticed we had a broken outside outlet cover & replaced it with a better model! Awesome Job! Hire This Navy Vet!!!

Very good work and nice gentleman.Recomend to anybody needing electrical work.No problem great guy.

John was both professional and personable which made me feel confident I hired the right person for the job. He first asked some questions to determine the cause of the problem and how best to resolve it. He walked me through everything he did and gave me a layman's explanation of the work. I highly recommend John for any electrical projects.

John did an excellent job mounting my flat screen television to my living room wall, in spite of having to deal with smaller than average studs. His time estimate and original quote were spot on. He is very personable and a pleasure to work with. I highly recommend John and plan on using him in the future for my electrical needs.

John was a pleasure to work with. He was efficient, knew his stuff, and was extremely helpful. I would hire him again in a heartbeat.

John was excellent. Called him on a Sunday afternoon to help with a wiring problem. He was at our house in under 30 minutes. Problem fixed in 15. Will highly recommend him.

Work was done quickly to my satisfaction

They were very effecient and cleaned up everything. I was very happy and please.

Good work. Value for money.

John P Tierney III says and looks like is a highly experienced and educated professional ( masters in electrical engineering ) & licensed ( holds multiple levels of NH gas and electrical licenses) . Hired him for a small job to connect my new hybrid heat pump electric water heater with a line from circuit breaker. Job well done no issues so far.

Was fast, professional, and did a great job - Thank you!

Fast, Friendly, Beautiful Work.... Will call on him from now on!~

John was excellant. After a short phone conversation I could tell that he knew all the ins and outs of installing a bath fan. John was at my house 20 minutes later and assessed what was needed to be done and what was unnessessary. He called back 3 hours later to say he was ahead of schedule and could install my fan by the end of the day. He did a great job for a very fair price. I was expecting to pay $100 more . John's the first person I'll call for any future electrical work

John was absolutely great - friendly, professional, VERY knowledgeable! He stopped by to assess the job and after providing several options he made a quick trip to Home Depot and came right back and completed the job right then! He will be the first person I call for any other service.
