"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

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

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.

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

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.
