Radon testing

Why test for radon?

Radon is a colorless, odorless radioactive gas which is present in all homes. Radon is the second leading cause of lung cancer in the US and it is estimated that between 15,000 and 22,000 lung cancer deaths each year are related to radon. According to the EPA, almost all of Montana is classed as Radon Zone 1 – the highest radon concentration zone in the US, where the average house has a radon concentration higher than the maximum recommended level of 4 pCi/L. By testing for radon, you can find out whether your house needs a radon mitigation system to lower the radon concentration to a safe level. This can often be used in negotiations when closing on a house, saving you thousands of dollars. And if the results show a low level of radon, you can rest easy.

Our radon service

We use state-of-the-art radon detection equipment to quickly and accurately determine the radon levels in your home. Our continuous radon monitors contain four radon sensors in each unit, allowing for high accuracy and precision, as well as fast results. 

As an InterNACHI certified radon tester, we perform our testing according to EPA guidelines. Our tests will typically take 48 hours to complete (never less than this, but sometimes more if necessary).

We perform the data analysis personally, meaning that once the test is complete, you will have the report within a few hours. 

This is much quicker and more accurate than basic activated carbon tests that many inspectors use, which require the test kit to be sent to a laboratory and analyzed, often taking more than a month. By that time, the house has likely been closed on and you’ve lost the opportunity to have the seller pay the thousands of dollars required for a radon mitigation system.

Note: radon testing is not included in our standard home inspection and is an additional fee.

We also provide radon testing services as a standalone service (i.e. without having us perform a home inspection).
