    John was great from start to finish. To being super flexible with initial scheduling and understanding our needs, to doing a fantastic job with the final report - John made himself available every step of the way and walking me through aspects of the inspection that needed special attention. Will highly recommend, especially if like us you are brand new to the home buying business :)

    Buying my first home has been an overwhelming experience. Pam was incredibly helpful in getting our appointment set up and answering all my questions. John arrived early to the appointment and was so detailed! He answered all my questions and provided me with everything I needed. the house is 100 years old and we got his 47 page report plus a recall report on all the appliances in less than 48 hours! I highly recommend!

    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.
