Don't schedule your radon mitigation until you have talked to Clear Conscience Radon!

Not all radon companies are created equal! Many radon companies that you'll talk to try to save a few bucks by using cheap inferior products and employ uncertified personnel that are only looking for a paycheck but not us! I have been a certified radon professional for more than 10 years & continue to further my knowledge through experience, attending international radon symposiums and participating in continuing education functions. I am present at every radon mitigation we schedule and we always leave the area we work in cleaner than what we found it. This is my livelihood not just a part-time paycheck so I make sure that every client is happy with our work. Don't take my word for it just read my reviews here and on Google. I look forward to earning your business Jason Mantych Clear Conscience Radon 816-651-6123 "HomeAdvisor Best of 2019, 2018 & 2017 Winner"

Review by in Overland Park, KS
I hired Jason for a radon mitigation job in April 2020. He and I discussed the options for mitigation and settled on a sump pump option with exterior venting. The job was done quickly and on my schedule. Jason offered a couple day test to measure new radon numbers. The average radon had gone from 8.2 to 1.0, an 87% decrease. I did have to call him back a week or so later when I noticed the silicone caulking wasn’t sealed at the sump pump. I’m not sure whether it was installation error or whether the silicone was sucked out of place due to vacuum. Either way, he came the next day. I’d recommend him and his crew.

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.
