    John Johnston Contracting is a great company with excellent customer service and a rapid response time. We were always kept up to date on the progress of the gutter cleaning. Everything was fixed by the technician very properly.

    I called the John Johnston contracting to seal the driveway. They arrived on schedule and gave me a call before they arrived. The work went off without a hitch, and the overall product was good.

    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.
