"They installed a radon system in our home. It was a little complicated, but they completed the work fairly quickly. They were very friendly and professional, you can tell they knew what they were doing. In less than 24 hours, the radon levels in our home were normal."

"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"All of the Radon Be Gone staff I dealt with were very professional. They designed the system so it vents in a back corner of the house and is barely visible. The staff delivered the external vent pipes several days in advance of the installation so I could paint them to match the exterior of my home. They were timely, polite and very competent at their work. The radon readings in my home were reduced to a very low and safe level."

"The installation of radon system was good. They were on time and very nice and cleaned up well afterward but have not been able to get a hold of the company since then to schedule retest. The phone number indicates that voice mail is full and have texted the number with no response and have also emailed them."

Radon Detection and Reduction questions, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

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 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.

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

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.
