Residential Radon Testing Services IN Cottage Grove, Minnesota


Protect Your Family with Reliable Home Radon Measurements
Radon is an invisible, odorless, and tasteless radioactive gas that naturally occurs in the soil and rock beneath our homes. It enters houses through cracks, gaps, and openings in foundations, basements, and crawl spaces. While it is undetectable without specialized equipment, radon exposure is a serious health concern. Long-term exposure to high radon levels can significantly increase the risk of lung cancer, making testing an essential part of protecting your home and family.
In Minnesota, geological conditions often lead to higher-than-average radon concentrations in residential properties. Even modern, well-sealed homes can be affected, as radon gas can accumulate in enclosed spaces regardless of the home’s age or construction style. The only way to know if your property is safe is through accurate, professional testing.

FREQUENTLY ASKED QUESTIONS
Why is radon testing important for Minnesota homes?
Minnesota’s soil composition often leads to higher indoor radon levels. Testing identifies these levels so homeowners can take action before health risks develop, ensuring a safer living environment for the entire household year-round.
How often should my home be tested for radon?
It’s recommended to test every two years, or sooner after renovations or mitigation installation. Regular testing ensures your home remains safe as environmental conditions and building structures change over time.
Is short-term testing enough for decision-making?
Short-term tests provide quick results but may not capture seasonal fluctuations. For the most accurate assessment, especially for long-term health decisions, long-term testing is recommended to determine a reliable yearly average.
What happens if my home’s radon levels are high?
If elevated levels are detected, we recommend professional mitigation to reduce concentrations. After installation, follow-up testing ensures the system is working effectively and maintaining safe indoor air quality levels.
Are radon tests disruptive to daily life?
No. Testing devices are discreet, silent, and require no special preparations beyond maintaining normal ventilation patterns. You can continue regular activities while the test is in progress without interference.
Can I perform radon testing myself?
DIY kits are available but often less accurate due to placement or handling errors. Professional testing ensures precise measurements, proper protocols, and results you can confidently use for health and property decisions.
How long do radon test results take?
Short-term test results are typically available within a few days after completion, while long-term tests provide results after the full testing period. We ensure fast, accurate reporting so you can take prompt action if necessary.
