Radon Detection and Reduction questions, answered by experts

A professional indoor air quality inspection takes anywhere from one to three hours, depending on the size of your home and the number of necessary samples. After the test, the specialist will discuss the findings, but you won’t get a full written report for 2 to 10 days, though you can ask your pro to expedite the process, if needed. 

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.
