Never a conflict

The Home Detective does not mitigate Radon.   We only provide professional radon testing services so there is never the  possibility for a conflict of interest. 

How is Radon  Detected?
The Home Detective uses state-of-the-art continuous radon monitors to identify the presence and quantity of radon.  This is more favorable method than charcoal canisters and do-it-yourself tests because or monitors will detect tampering and power interruptions. Our monitors have a battery back-up system in case power is lost during the evaluation. These added safeguards assures greater consistency and testing results. 

The New Montgomery County Radon Law:

As of October 1, 2016, Montgomery County law requires a radon test be performed on most

  single family homes and town homes prior to settlement. This excludes condo's and  co-op's. 


Radon Information

How do I know the test is accurate?
We are members of NRSB (National Radon Safety Board) and hold the designation of "Radon Measurement Specialist"   We follow EPA established protocols in the testing and analysis of radon. Our continuous radon  monitors are calibrated and cross-checked in accordance with EPA guidelines.  Radon testing requires a minimum of 48 hours and our test results go out the same day the test is completed.....there's never a long wait for lab results.

What if my home has elevated radon?
Don't panic.  Radon is one of the easiest issues to correct  in a home.  The EPA "ACTION LEVEL"  is 4 piCu/L.  This means that a home which tests at 4.0 or above, should be mitigated.   The typical cost for simple mitigation is about $1000. 

Radon is never a reason to walk away from a home purchase.

    ​What is Radon?

                 Radon is an odorless, tasteless gas produced from the breakdown of naturally occurring Uranium and Thorium in soil and water.

                The US EPA classifies Radon as a "class A" carcinogen and the #1  cause of lung cancer in non-smokers.
