I had a few small repairs that needed to be completed. Mark was great, prompt and professional. I would hire him again (in fact I did). I will refer him in my real estate business to my clients.

Mark was extremely professional and allowed me to observe and learn as he did the work. His friendliness and knowledge is exactly why I will hire him to complete a full electrical upgrade.

Project: Install or Replace Exterior Building Lighting - For Business
I had a fantastic experience with Mark and his colleague. They installed exterior lamps and ceiling chandelier at a competitive price. They did a great job and were very thorough. Great response time from inquiry to completion.

Project: Upgrade an Electrical Panel or Wiring
Mark was very responsive, handled all the behind the scenes details (permit, Eversource, etc.) promptly and worked around my schedule to complete the job quickly. I'm very happy with the finished project. I thought his pricing was very reasonable.

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.
