    Steve explained the process and got my approval as to where to put things with the mitigation system. My radon level went from 7 to below 1. He charged a fair price compared to other quotes that I received and was professional as well as friendly. I would definitely recommend recommend him to others.

    Steve was very nice! Honestly, I had put my info in to get estimates from multiple people. He was the first to contact me. Other companies contacted me after and were higher than his quote. For me, it was an easy decision. One, he was below cost and two, he had great reviews. I always go off of reviews of others. Steve was on time and always made sure to keep me in the loop with things. I have already referred him out to my realtor and mortgage officer. 5 stars across the board!! Would for sure recommend him to anyone looking to get rid of radon. Thanks, Steve for the work!

    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.
