"You need to ask the technicians what to do and when regarding the re-test. The information we received was insufficient to know what to do afterwards and our re-test was delayed X 4 days because of lack of communication. Otherwise VERY Happy with the actual work and costs for the work."

Radon Detection and Reduction FAQs, answered by experts

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

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.

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.

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.

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