    5.0 Candace Y. North Berwick, ME

    They finished a job that my husband had been working on. My husband said,â they did beautiful work.â He doesnâ t use that word. They were fast, efficient, friendly and accommodating. Would hire again and recommend to anyone.

    5.0 Marsha I. Wells, ME

    Ed was great! He explained what was wrong and how he would replace the well pump only. He said the rest of the well was in good shape. When finished he cleaned up, took time to explain what needed to be done in the fall. J was thrilled to have water again.

    5.0 Ann D. York, ME

    Chad was very knowledgeable and explained everything as he inspected and then replaced the well pump. We will definitely turn to him for future maintenance.

    5.0 Matthew C. South Berwick, ME

    Hired them to test my water/evaluate my current water treatment system. Ed was very knowledgeable, and knew everything I had questions about. Our test came back high in Radon, and he reached out before I even called to talk options for mitigation. He sent me a quote and ordered the system within a day.

    5.0 Robert B. Gorham, ME

    We were without water for 6 days, a lot of the plumbers we contacted would not even return our call. We spoke with McMahons on Friday and by Monday afternoon we had water. Caleb and Jeff were awesome, they drove a new driven point for us in no time, got more water than we have had in years, very easy to talk to and had good answers and if he was nor sure Caleb would contact his Brother or Dad who have more experience. We have a new plumber! Oh the people that we dumped over 5000.00 dollars with 2 months ago for a new pump and water treatment that are located in Lewiston never returned my call. Thanks McMahons!!!

    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.
