"What a relief to find Anthony and ALO. After a mail-in radon test revealed extremely high levels of radon, we called The Big Guys in town. Do not get me started? .luckily I called ALO next. Their price was MUCH more reasonable and they scheduled me 5 days out! Anthony was great at keeping us informed re: times. He also made it clear that he would start with a basic mitigation package, and if the radon levels were still too high, they would then start adding more expensive fans/additional suction points, etc. There was an up front price list for all these options. Thankfully after 2 days, the work was done and tests soon revealed nearly non-existent radon! I highly recommend these guys."

Radon Detection and Reduction questions, answered by experts

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

If high radon levels are detected, steps include sealing entry points, installing a mitigation system, and retesting the air regularly to ensure reduced levels.

You can buy DIY radon test kits from a home improvement store and conduct radon testing, but these tests are often inaccurate. No matter the result, you should supplement DIY testing with professional radon detection and analysis. DIYers only have access to passive radon tests, which aren’t as reliable as active tests that professionals use. Plus, it’s very easy for DIYers to make mistakes during testing, leading to inaccurate results. If you’re moving into a new home, have concerns about radon, or are due for an updated test, hire a professional. 

In most states, radon testing companies don’t need to be licensed or certified by the state, but the companies that analyze the test results and develop radon mitigation protocols do. You should choose a radon testing company that suits your needs, but before hiring a mitigation specialist, check our state licensing tool to make sure the company is properly certified.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.
