"The representative, Madeline, was extremely prompt in fielding my inquiries and thoughtfully educated me on the process with proper expectations of timeline. The service was performed exactly as described and extra care was given by contacting me before taking the samples to make sure the areas chosen were acceptable to me. She offered a courteous phone call immediately upon receiving test results so that I could know right away without having to wait for the report that did follow shortly after the same day. This company has my highest recommendation to others."

"Precise Home Inspections helped my husband and I properly identify the mold in our home. For months we were suffering from allergies, and were unaware of the cause. It was not until someone referred me to PHIS for an Indoor Air Quality Testing, that we discovered the source of our problem. They were highly recommend to us and after the quick and easy appointment made, the fantastic service and turn around, we will continue to recommend them. The entire Precise team gets 5 stars!"

Radon Detection and Reduction FAQs, answered by experts

Radon is a cancer-causing radioactive gas that poses serious health risks, infiltrating homes through foundation cracks and unnoticed spaces.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. 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 preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

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 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.
