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 9 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 are the only radon company that cares enough to use a certified electrician for each radon mitigation. 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 2017 & 2018 Winner"

Project: Mitigate Radon Gas
Jason at Clear Conscience was prompt and professional with all communication, scheduling and project completion. He is easy to talk to and answered all questions I had about the project. Janson bid the job AND completed the project himself with the help of 2 others on his team. He IS the Pro and his company is certified by mitigation regulatory agency(s). Jason explained the mitigation process and specific application related to our home parameters when here bidding the job. Don't miss the website video that walks a viewer through the project steps as well. The site is a wealth of information about all things radon and mitigation. He provided references for jobs recently completed in my area. Great clean-up. Price was right! Highly recommend this company to anyone! Thank you Jason!

Review by in Weatherby Lake, MO
How business should be done. Showed up on time, didn't try to upsell, listened to me and answered my questions, didn't try to cut corners to make it easier for themselves, cleaned up after themselves, and it worked, my radon levels are almost nonexistent now. I wish they offered regular home maintenance so I could use them again for other tasks!!! I highly recommend this company.

Jason gave a good explanation of how they were installing the system and how it worked. The installation was quick and the price better than others.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
