Trusted Home Radon Testing Experts in Los Angeles for Residential and Real Estate Properties

You won’t see it. You won’t smell it. But radon could be quietly poisoning the air inside your home.

Radon is a radioactive gas that forms underground and moves upward through the soil. It enters homes through tiny cracks in the foundation, gaps in the flooring, or even the crawlspace beneath your feet. Once inside, it lingers—and builds—without any sign.

This isn’t just an air quality issue. Radon is the #1 cause of lung cancer among non-smokers, responsible for over 21,000 deaths in the U.S. each year, according to the EPA. And it doesn’t stop there—recent medical studies have shown that patients with Parkinson’s and Alzheimer’s carry far higher levels of radon in their brain tissue compared to those without. The long-term risks are real.

In a city like Los Angeles—where homes range from hillside retreats to tightly sealed new builds—the only way to know if you’re breathing radon is to test. Home radon testing in Los Angeles is the first and most important step in protecting your household. No neighborhood is immune. No home is guaranteed safe until it’s measured.

If you’re living in LA and haven’t tested your home, it’s time. A simple test can protect your health, your family, and your peace of mind.

Radon is a Risk in Los Angeles—Even If You Think You're Safe

Elevated radon levels have been recorded across Southern California, including Los Angeles. The soil composition beneath Los Angeles homes, combined with seismic activity and variable building construction, makes radon intrusion more common than most homeowners realize. Whether your home is:

Brand new or decades old
Built over a crawlspace or slab-on-grade
On a hillside or tucked into a flat lot
Fully renovated or original condition

It can still have high radon levels. The only way to know is to test.
