Radon: The Invisible Risk in Your Home
Radon is a colorless, odorless radioactive gas that can enter any home through cracks and openings in the foundation. It can affect homes with basements, crawl spaces, or slab foundations, so testing is the only way to know your level.
WHY TESTING MATTERS
The Health Risks of Radon
Radon is a naturally occurring radioactive gas released as uranium breaks down in soil and rock. It has no color, odor, or taste, and it can seep into homes through foundation cracks, sump pits, crawl spaces, and gaps around pipes. According to the U.S. EPA, Radon is the leading cause of lung cancer among non-smokers.
Because levels vary from house to house, even next door, testing is the only way to know if your home is safe. A professional Radon test during your inspection gives you accurate data before you buy, sell, or renovate, so you can plan mitigation with confidence.
Our Radon Testing Process
1. Device Placement
A calibrated Radon monitor is placed in the lowest livable level of the home, away from drafts, vents, and exterior walls.
2. 48-Hour Monitoring
The device records Radon levels continuously for at least 48 hours under closed-house conditions to ensure accurate readings.
3. Results & Guidance
You receive a clear report comparing your average level to the EPA action level of 4.0 pCi/L, along with recommended next steps.
Radon FAQ
What is Radon?
What Radon level is considered safe?
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It is colorless and odorless, and can enter homes through foundation cracks and gaps.
The EPA recommends taking action to reduce Radon when levels are 4.0 picocuries per liter (pCi/L) or higher, and suggests considering mitigation between 2.0 and 4.0 pCi/L.
How is Radon tested?
How is Radon mitigated?
Short-term testing lasts at least 48 hours and is commonly used for real estate transactions when time is limited. Long-term testing lasts 90 days or more and provides a more accurate picture of changing Radon levels over an extended period.
The most common method is sub-slab depressurization: a vent pipe and fan draw Radon from beneath the foundation and release it safely above the roofline. Sealing cracks supports the system.
What type of homes are at risk for Radon?
Any home can have Radon, regardless of age, size, or foundation type. Homes with basements, crawl spaces, and slab foundations can all be affected, so testing is the only way to know your home’s Radon level.
If my home had low Radon before, should I test again?
Yes. Radon levels can change over time. Weather, temperature, wind, barometric pressure, soil conditions, ventilation, renovations, and foundation changes can all affect the level in your home. A previous low result reflects only the conditions at that time, so retesting is worthwhile—especially before buying, selling, or making major changes to the home.
