"April helped us line up a last minute inspection for a new build for us. They were extremely thorough and found a few significant problems that we were able to take to the builder. They included lots of photos of the issues which was helpful. They used thermal imaging too which was new to us but helps detect problems that may not have been seen otherwise. We got our report along with a summary the next day and had excellent communication and follow through. We will definitely use them in the future and highly recommend."

Radon Detection and Reduction questions, answered by experts

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

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.

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.

No level of radon is technically safe, but since it is naturally present everywhere, it is impossible to avoid entirely. 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 action to reduce radon levels if your home's test results are between 2 and 4 pCi/L or higher.

Abatement includes sealing entry points and venting with systems that reduce radon levels below recommended EPA limits. It is handled by certified professionals.
