Radon Detection and Reduction questions, answered by experts

It is worthwhile to get radon testing done, especially if you haven’t in the past and don’t have active radon monitoring set up in your home. According to the American Lung Association, radon is a potential issue in all states, and testing is the best way to determine if it’s a current problem in your home. Radon testing includes professional tests that determine ongoing radon levels in your property, and it usually includes a mitigation protocol to help you decide what measures to take to protect your home and household members.

Radon is a colorless, odorless gas that can cause lung cancer; testing ensures safe indoor air quality.

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

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.

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