Radon Detection and Reduction questions, answered by experts

The cost to replace a radon fan ranges from $300 to $600 for the fan itself, with installation adding an additional $200 to $500. Overall, the total cost for replacement can range from $500 to $1,100, depending on factors such as the fan model, home size, and local labor rates. If the fan is part of a larger radon mitigation system, the price may be higher.

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.

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.

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.

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.
