Radon Inspection
Radon is one of the most overlooked indoor air quality risks in homes today, yet it is also one of the most dangerous. Because it is colorless, odorless, and tasteless, many homeowners are completely unaware of its presence until a professional radon inspection is performed. At Aspen Radon, we specialize in providing accurate, science-based radon inspection services designed to protect families and ensure homes meet safe air quality standards.
With decades of experience in the field, our team understands that every home is unique. That’s why we approach each radon inspection with precision, using advanced testing equipment and industry-approved protocols to deliver reliable results you can trust.
What is a Radon Inspection?
A radon inspection is a professional evaluation of indoor air to measure the concentration of radon gas within a home or building. Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil, rock, and water. It can enter homes through foundation cracks, crawl spaces, sump pumps, and other openings.
Unlike standard home inspections, a radon inspection focuses specifically on air quality and gas concentration levels. The goal is to determine whether radon levels exceed the EPA action guideline of 4.0 pCi/L and whether mitigation is necessary.
At Aspen Radon, our inspection process is designed to be both thorough and non-intrusive, ensuring homeowners get accurate readings without disruption to their daily routine.
Why a Radon Home Inspection is Essential
A radon home inspection is not just a precaution—it is an essential step in protecting your household’s long-term health. According to the EPA, radon exposure is the second leading cause of lung cancer in the United States, responsible for thousands of deaths each year.
Many homes in Colorado and surrounding regions are at higher risk due to the natural geology of the area. Even newer homes or well-sealed properties are not immune, which is why every homeowner should consider routine radon testing.
Here’s why scheduling a radon home inspection matters:
It identifies hidden radon risks before they become dangerous
It ensures your home meets health and safety standards
It provides peace of mind for families, buyers, and sellers
It helps guide mitigation decisions if elevated levels are detected
Whether you are purchasing a new property or living in your forever home, understanding your radon levels is a critical part of responsible homeownership.
How Radon Testing Home Inspection Works
A radon testing home inspection involves placing specialized monitoring devices in the lowest livable areas of your home, such as basements or ground floors. These devices measure radon levels over a specific period, typically 48 hours for short-term tests or longer for more comprehensive evaluations.
At Aspen Radon, we follow strict testing protocols to ensure accuracy:
Initial Assessment – We evaluate the home layout, foundation type, and ventilation conditions
Device Placement – Professional-grade radon monitors are strategically installed
Monitoring Period – Continuous measurement of radon concentration levels
Data Analysis – Results are analyzed and compared against EPA safety guidelines
Detailed Reporting – Homeowners receive a clear, easy-to-understand report with recommendations
Our radon testing home inspection process is designed to eliminate guesswork and provide scientifically valid results that homeowners can rely on.
Radon Mitigation System Inspection: Ensuring Your System Works Properly
Installing a mitigation system is only the first step—ensuring it continues to work effectively is equally important. A radon mitigation systeminspection evaluates the performance, efficiency, and integrity of an existing radon reduction system.
Over time, systems may experience issues such as:
Fan failure or reduced performance
Pipe leaks or disconnections
Improper sealing around foundation entry points
Blocked suction points or airflow restrictions
During a radon mitigation system inspection, our experts check all components, including the fan, piping, and suction points, to confirm the system is actively reducing radon levels as intended.
If any issues are found, we provide clear recommendations and solutions to restore full system efficiency.
When Should You Schedule a Radon Inspection?
Homeowners should consider scheduling a radon inspection in the following situations:
Before purchasing or selling a home
After installing a new mitigation system
If it has been more than 2 years since the last test
After major renovations or foundation work
If occupants experience unexplained respiratory issues
Regular inspections ensure that radon levels remain within safe limits and that mitigation systems continue functioning properly.

The Health Impact of Radon Exposure
Radon exposure occurs when radioactive particles are inhaled over time. These particles can damage lung tissue and significantly increase the risk of lung cancer, especially for smokers or individuals with prolonged exposure.
The danger lies in its invisibility. Without a proper radon inspection, there is no way to detect it on your own. This is why health organizations worldwide strongly recommend routine testing for all homes.
Understanding Your Radon Inspection Results
After your inspection, you will receive a report indicating radon levels measured in picocuries per liter (pCi/L).
Below 2.0 pCi/L – Low risk, generally considered safe
2.0 – 4.0 pCi/L – Moderate risk, monitoring recommended
Above 4.0 pCi/L – Action required, mitigation strongly recommended
If elevated levels are detected, Aspen Radon will guide you through mitigation options tailored to your home’s structure and conditions.
Frequently Asked Questions About Radon Inspection
How long does a radon inspection take?
A standard radon inspection typically takes about 48 hours for short-term testing, which is the most common approach used in residential properties. During this period, a continuous monitoring device measures radon levels in the lowest livable area of the home under normal living conditions. For homeowners seeking more detailed and reliable long-term data, testing may extend to 90 days or longer, sometimes up to a full year. Long-term monitoring is recommended because radon levels naturally fluctuate due to seasonal changes, weather conditions, and ventilation patterns, giving a more accurate picture of year-round exposure.
Is a radon home inspection necessary for new houses?
Yes, a radon home inspection is still necessary even for newly built homes because radon comes from the natural breakdown of uranium in soil and can enter any structure regardless of age. New homes are often built with tighter construction and improved energy efficiency, which can actually trap radon indoors and increase concentration levels. Since soil composition and foundation design vary from property to property, the only way to confirm safety is through proper testing, making radon inspections essential for all homes, including brand-new constructions.
What is included in a radon testing home inspection?
A radon testing home inspection includes several key steps: a professional assessment of the home layout, strategic placement of calibrated testing devices in the lowest occupied areas, continuous monitoring over the testing period, and detailed data collection of radon levels. After testing is completed, the results are carefully analyzed and compared to EPA safety guidelines. Homeowners then receive a comprehensive report that clearly explains radon concentration levels, potential health risks, and professional recommendations on whether mitigation is necessary.
How often should I schedule a radon mitigation system inspection?
A radon mitigation system inspection should generally be scheduled every 1 to 2 years to ensure the system continues to operate effectively and safely. Over time, system components such as fans, piping, seals, and suction points may wear out, become loose, or lose efficiency without obvious signs to the homeowner. Regular inspections help confirm that radon levels remain low and that the system is performing as intended, especially after home renovations, foundation changes, or HVAC adjustments that could affect airflow and system performance.
Can radon levels change over time?
Yes, radon levels can change over time, even in the same home, due to a variety of environmental and structural factors. Seasonal changes often play a major role, with higher levels commonly observed in winter when homes are sealed tightly and ventilation is reduced. Other factors such as weather patterns, soil moisture, foundation shifts, ventilation habits, and home renovations can also influence how radon enters and accumulates indoors. Because of these fluctuations, regular testing is essential to ensure ongoing safety and to confirm that any mitigation system in place continues working properly.
