    5.0 Jonathon W. Acton, ME

    Very time efficient knew what he was talking about. He arrived on time

    4.0 Alex W. Saco, ME

    As others have said - very friendly, very professional, timely, and absolutely helped me get to the bottom of a frustrating well problem. The only downside was their cost was ridiculously high ($1500 for a 60min job that typically runs closer to $750/1k) and we only paid because we didn't have another option at the time.

    5.0 Giovanna G. Parsonsfield, ME

    Very responsive. Came to my home the same day I called and quickly fixed the issue. They provided feedback on some other areas that may require attention in the future.

    5.0 Connie P. Springvale, ME

    Came immediately. Knowledgeable friendly. Price was high for the 20 minutes there and a connection for tubing. I would mostlikely use them again

    5.0 Nancy J. Berwick, ME

    Jeff was great. On time, professional and explained everything. The quality of work was excellent. Reasonable price.

    5.0 Donald J. Standish, ME

    He was on time, explained what he was doing to my husband and completed the job quickly. He also recommended someone to help change out the pipes in our basement. We were pleased. He was very professional. I would recommend him.

    Response from Company:

    Thank you so much for giving us the opportunity to service you!

    5.0 Mae R. Cape Neddick, ME

    McMahon provided quick response, quick service, and professional service at a reasonable price.

    4.0 Kevin L. Cape Neddick, ME

    Quality of work was excellent. Had some issues with scheduling and communication, but not major and just an oversight.

    5.0 Cristian F. Sanford, ME

    They were awesome and super helpful

    HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

    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.
