Review by in Lincoln, NH
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.

Review by in Hollis, NH
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!!!

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 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.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
