5.0 Jeremy G. Denver, CO

Very smooth and straight forward process. Affordable and the quoted price was what we paid. Very professional and installation was quick.

5.0 Mary B. Englewood, CO

Nicholas was a quick to respond. He provided instruction and demonstrated Great integrity when the numbers showed. I didn't need the service right now and didn't push me to buy.

5.0 Becky Z. Westminster, CO

I would highly recommend Absolute Radon Safety. The price was competitive and the system warranty canâ t be beat. JD arrived on time and completed the work in less than three hours. He was courteous, knowledgeable, and ensured we understand the system and how it works.

5.0 J Z. Englewood, CO

Absolute Radin replaced the radon system in my 30-year old home I was selling and also installed sump pumps in my new home. They did excellent work.

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.
