    Furnace was repaired then when it stopped working the next day they came back to fix it quick for no charge. Great customer service!

    4.5 Paul S. Portsmouth, NH

    Installed a new sump pump works great.

    5.0 Jay H. Hampton, NH

    They fit me in right away and came when they promised. They're very professional and friendly. They know their business. It turned out to be a minor repair and I appreciate their being honest with me instead of trying to milk the job to create a higher bill. They'll be my GOTO from now on.

    Joel and Gary made a teriffic team for the installation of a replacement boiler. They know what to do and they get the job done quickly, properly and neatly.

    4.0 Brian H. Newmarket, NH

    The company uses a big markup on all parts used.

    5.0 Susan F. Rye, NH

    Very good customer service: I was able to get an appointment within days. Two very friendly, knowledgeable, professional guys showed up, did a great job, and answered all my questions thoroughly and honestly...no up-sell, which I appreciated. It's nice to have found a reliable plumbing and heating company.

    HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

    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.
