"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.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

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

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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