Radon Detection & Reduction

"Installed radon mitigation system in basement. Pros: 1) reduced overall radon levels by about 75% 2) they did the work in extreme cold temps 3) done in about 4 hours Cons: 1) They arrived late (although they did call to let me know) 2) they did not wear boot covers or put down any floor protector when walking on my carpet 3) they set dirty toolboxes and caulk guns directly on carpet 4) exhaust pipe is too close to roof peak and can be seen from street view of house Overall, good job. I can live with seeing the pipe from the street. I would recommend based on the overall work."

Residential Home Inspections and radon testing. Before i became a home inspector I built houses for 15+ years. I decided to open this small family owned business because I find joy in helping people understand their huge investment in buying a house.

Radon Detection and Reduction questions, answered by experts

Through air sampling devices and surface swabs in key areas of concern.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

Costs depend on property size, test types, and additional services like mold sampling.

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 testing costs around $450 on average, but you could pay between $150 and $800 for testing, depending on a few factors. The size of your house is one of the most significant cost factors, as your radon professional will have to set up additional tests for homes with larger footprints. The type of test can also have an impact on the cost. Finally, some radon testing companies will include a recommended protocol for radon mitigation, while others might charge $50 to $100 extra.
