Tom was professional and knowledgeable. We hired him to do the electrical wiring for our basement remodel. Detailed quotes were provided and permits were obtained. Would definitely hire him again.

Project: Install a Fixed Generator
Initially communication was a little slow. But I am definitally glad I stayed with Tom. He walked us through the entire project and his support during and after was great. I would recommend him to anyone. Would hire him again. Felt very comfortable with his job knowledge and experience. The project was to purchase and install a generator for the house when there was a loss of power. Also pricing was very competitive. During a power outage after installation was complete, (he contacted us) to make sure everything was ok. Very impressed!

Review by Phyllis K. in Chelmsford, MA
Project: Install a Fixed Generator
There was extreme carelessness during install that would not be known immediately by the end user (hidden in trench). Wires to my well pump were ripped, causing the pump to burn out, and I had to replace my pump. I notified Thomas, and after initial contact, have heard nothing back. I have been set back a great deal of money due to actions that he is not being responsible for. I am not happy with the fact that he will not be responsible and be in contact with me to help me. At least put me in contact with his insurer.
Response by Thomas Mondello: Hi Phyllis, It is very unfortunate that you are now experiencing such dissatisfaction with our services. I know we enjoyed doing business together in the past. We completed installation of your 16kw Generac Gaurdian in the beginning of October 2018 which included a 80? trench for the electrical. As we dig any trench we are very careful in our efforts not to damage anything that would be located within the trench and make thorough inspections of those things were located in the trench. If we do find that anything was damaged we make the appropriate repairs. You contacted me the following days after you had a well company come the replace your

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.
