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."

Radon Detection and Reduction questions, answered by experts

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

The only way to determine if you have a radon problem in your home is to have professional testing done. You can buy DIY radon test kits, but these are sometimes inaccurate in certain temperatures and humidity levels, and they don’t paint the entire picture in terms of your radon exposure. Scheduling testing once every two to five years is best. You can also look out for the following symptoms, which, according to the American Cancer Society, are symptoms of radon exposure:

  • Shortness of breath

  • Cough

  • Tightness in the chest

  • Difficulty swallowing

  • Hoarseness

Avoid opening windows and keep doors closed during testing to obtain accurate readings.

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