    These guys know what they are doing. Friendly, professional. Did exactly what they said they would, with unbelievable results after testing. They showed up on time, and finished in just over two hours. He took time to discuss every aspect of what they were doing, and made excellent installation decisions based on what we needed. I highly recommend 1st DeFense for your Radon mitigation needs.

    Steve and team were fantastic. Quick to respond, schedule and did an excellent job walking us through the process and ensuring we had everything we needed to be comfortable with the process and results. Less than a week after contacting, we have almost zero radon and are feeling very comfortable in our home now. Great work from great people!

    The whole process was easy including him coming to the house and explaining everything he would do. The job was completed quickly and professionally and all is well. The price was reasonable with no hidden fees.

    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.
