"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

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

A homeowner can install a radon mitigation system on their own. But it’s a challenging DIY that requires a lot of knowledge about radon mitigation as well as familiarity with local regulations. You do not want to risk an improper installation that leaves the system unable to detect radon or gives it a shortened life span. Relying on a professional is the surest way to guarantee a successful installation.

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.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Radon detection is crucial as prolonged exposure to radon gas, a leading cause of lung cancer, poses significant health risks in residential environments.
