"Ron from Radon Solutions of Southern Indiana arrived right when he said he would and cared enough to take the time and explain what he found from the test and all the solutions that we could use. From the initial appointment to when he left from putting in the mitigation system he was very personable and had great customer service. With his reasonable prices, customer service, and great final product I definitely recommend using his service to anyone else, in fact my own mother in law is getting a system installed by him in her new house she just moved into."

"The project included removing the den carpet, tile and mastic and encapsulating the subfloor. This was needed to prepare for a remodel project. The project was performed in a timely manner. The workers performed the job according to the Asbestos Removal Rules and the flooring material was disposed of properly. Questions and concerns were addressed promptly. Very satisfied with the job."

Radon Detection and Reduction questions, answered by experts

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

The lifespan of a radon mitigation system depends on the type of system and its maintenance. With proper care, a system can last for many decades. Passive systems tend to last longer as they have fewer components that require replacement. Active systems, which have more moving parts like fans, generally have a shorter lifespan. For instance, water filtration devices and active pressurization systems require more frequent maintenance. While the system as a whole is durable, the radon fan in an active system typically has a lifespan of 5 to 10 years and will need to be replaced. As long as the fan is working, the mitigation system should function correctly.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.
