What Is Radon and Why Does Crystal Lake Have a Problem?
Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil and rock. It seeps up through the ground and enters homes through foundation cracks, construction joints, gaps around pipes, and even through solid concrete. Once inside, it accumulates — especially in basements and lower levels where ventilation is poor.
Illinois is one of the highest-radon states in the country. McHenry County, where Crystal Lake is located, consistently registers average indoor radon levels above the EPA’s action level of 4 pCi/L. That means if you haven’t tested your Crystal Lake home, there’s a meaningful chance you’re living with elevated radon right now.
Radon is the second leading cause of lung cancer in the United States, responsible for approximately 21,000 deaths every year. The EPA estimates that 1 in every 15 American homes has radon levels at or above the action level. In northern Illinois, that number is even higher.
The only way to know is to test.

If your results come back at or above 4 pCi/L, the EPA recommends action. If they come back at or above 2 pCi/L, many experts recommend considering mitigation, especially for families with children or anyone with a history of lung conditions.
Radon Mitigation System Installation
If your test results show elevated radon, we install a proven mitigation system that reduces radon levels in your Crystal Lake home by up to 99%. The most common and effective method is sub-slab depressurization — a system that draws radon from beneath your foundation and vents it safely outside before it can enter your living space.
- We assess your foundation type and radon entry points
- We drill a small suction hole through your basement floor
- We install PVC piping that routes from beneath your slab to above your roofline
- A quiet, energy-efficient fan runs continuously, pulling radon out before it enters your home
- We test again after installation to verify the system is working
Post-Mitigation Testing
After your mitigation system is installed, we conduct a follow-up radon test to verify your levels have dropped below the EPA action level. This confirmation test proves the system is working and gives you documentation for your records and for future home sales.
