"Thanks to Donna at Home Advisor for her great assistance. I have a multi-faceted problem with work performed by a licensed contractor after Hurricane Michael. Don Johnson is a pro roofing inspector, personable, capable and effective. His report was in my email in a few hours though that level of fast service was not requested. The report is complete, provides photo evidence, and is easy to read and understand. I am beyond satisfied with Home Advisor and Don Johnson."

Radon Detection and Reduction FAQs, answered by experts

Options include sub-slab depressurization, crawlspace ventilation, and sealing cracks. Choose based on home construction and radon levels.

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.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

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.

Installation typically takes 1-2 days, depending on the system and property layout.
