"Anthony was quick to respond, and within a few days, we were on his calender. When he arrived, he recommended a larger fan than originally quoted, and explained why (add'l cost was minimal). Cometed work in a thorough and timely manner, explaining everything along the way. Would strongly recommend ALO Radon to EVERYONE! Anthony is a breath of fresh air, in an area that is somewhat service challenged. Thanks so much!"

"They were very quick and seems like quality work. Guys were super friendly, answered all my questions and were very patient with my 3 y/o who constantly wanted to talk to them as they were carrying buckets in and out. Pretty spendy but i think drain tiling is expensive regardless."

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Yes, many systems include warranties for performance. Confirm terms with your installer.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.
