Radon Detection and Reduction questions, answered by experts

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

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

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.

It is possible to test for radon yourself using DIY radon test kits, but these at-home test kits should never be a replacement for professional radon testing. DIY test kits can provide some information about radon exposure in your house, but your indoor temperature and humidity can affect the results, as can improper usage of the test kit. You could save yourself some money by hiring a radon professional to begin with, and when it comes to your family’s safety, hiring an experienced professional to do the testing is usually the best option.

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.
