Radon Detection and Reduction questions, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

Many radon fans carry a five-year manufacturer's warranty. That said, your radon fan should last between five and ten years. Regular inspections will ensure the fan is operating properly. Unusual or exceptional noise coming from the fan or indications on your manometer or system monitor can immediately tell you that something is amiss.

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.
