"Everything went well. The repaired cracks have not leaked during recent storms. In addition, the radon test results after

the mitigation system was installed showed it is working and the radon in our basement is now at a very low level."

"Mark and his team are very knowledgeable, professional and hard working. Everything went great! Right from our first contact, Mark was very helpful and listened to our questions and answered them thoroughly. We received out quote quickly. The day they came out to install the equipment to mitigate the radon, they arrived on time and they were here the length of time they had told us they would be here. They set up another radon test before they left and came back several days later to pick it up. The radon was mitigated perfectly! We are very happy with Mark and his company, Metro Radon Control of St. Louis. Hire them with confidence!!"

"We wanted the house inspected because we were buying it. He did a thorough enough job of examining the outside and inside of the house. One thing that he didn't do... He didn't pull some building materials away from the basement storage area to examine the basement wall for cracks. I was a little surprised about that. He also didn't notice that the basement door was getting stuck when we tried to close it. We noticed it ourselves and asked the current homeowner's to fix it. However, he did notice the slow drain in the master bath. A leaky window in the master bedroom and that their was no GFCI outlet in one of the bathrooms. He tested for water/dampness in all the rooms and all of the windows. He communicated well and arrived on time. He took about an hour outside and inside. Also looked for termite problems in the house as well. Overall, I would hire him again."

Radon Detection and Reduction questions, answered by experts

No, air purifiers are not an effective way to reduce or remove radon. Radon is a radioactive, inert gas that cannot be filtered by standard air purifiers, which are designed to capture particulates like dust and mold. While an air purifier can improve indoor air quality by removing other pollutants, it should not be relied upon for radon. The only effective solution for high radon levels is a dedicated radon mitigation system.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

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.

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.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
