"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

There are steps you can take as a homeowner to remediate radon yourself. While a radon reduction professional can make the biggest impact in your home, you can make efforts to improve radon levels on your own by sealing cracks, increasing ventilation, and testing for radon regularly.

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.

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.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

The fan that pulls the radon out of the air needs to run continuously, so you may see an increase in your electric bill once you install the mitigation system. Additionally, you may see an increase in your heating or cooling bills, as the fan can cause some loss of hot or cool air.
