RADON LEVELS & BUILDING CONDITIONS
Radon can occur in buildings throughout the country, but some areas have a greater potential for elevated levels. Local risk information can help inform testing decisions, but it cannot predict the level inside an individual property.
Radon testing can provide buyers and sellers with documented information about indoor levels during a real estate transaction. Testing requirements or recommendations may vary depending on the transaction and location.
If a property has never been tested, there may be no reliable information about its current radon levels. An initial test establishes measured results that can be used to determine whether further action is appropriate.
Basements, crawlspaces, slab foundations, foundation openings, and other building features can provide pathways for radon to enter. Testing is the only way to determine whether these conditions are contributing to elevated indoor levels.
Renovations that change ventilation, insulation, air sealing, foundations, or other building conditions can affect how air moves through a property. Retesting can help determine radon levels after significant changes.
Radon levels can change over time, so an older result may not reflect current conditions. Retesting may be appropriate after several years, significant building changes, or when previous results were near or above recommended action levels.
(SHORT-TERM & LONG-TERM)
Short-term testing is commonly used for real estate transactions, initial screening, and other time-sensitive situations. Continuous radon monitors collect readings throughout the testing period, providing measured data that helps determine whether additional testing or further action should be considered.
Long-term testing measures radon over an extended period, providing a broader picture of average concentrations as levels fluctuate over time. By accounting for daily and seasonal variations, this approach can provide useful information about longer-term radon conditions within the property.
A certified technician reviews the building layout, lowest occupied levels, foundation type, and potential radon entry points. This step determines proper monitor placement.
The device records radon levels at regular intervals. Short-term tests typically run 48-96 hours, while long-term tests remain in place for extended monitoring.
You receive a clear report with measured results, data graphs, and interpretation. If levels exceed guidelines, we outline recommended next steps so you can address radon concerns with confidence.
We confirm the test type, property details, and timing. You receive clear closed-building instructions so conditions remain stable before testing begins.
We place calibrated radon monitors in the correct location, typically the lowest livable level. Proper placement ensures valid, representative data collection.
We retrieve the device and analyze the full data set. Results are calculated in picocuries per liter (pCi/L) and compared to the EPA action level of 4.0 pCi/L.
Residential Radon Testing
Homes, apartments, townhouses, and rental units can all be affected by radon, particularly in lower and below-grade living spaces. Testing provides property-specific measurements for homeowners, buyers, sellers, landlords, and residents who need to understand indoor radon levels.
Commercial Radon Testing
Understand radon levels in homes, apartments, and other living spaces with property-specific testing and clear, documented results.
Evaluate radon conditions in rental units, multi-unit buildings, and managed properties to support responsible property management and occupant safety.
Assess radon levels in schools, healthcare facilities, and other occupied buildings where understanding long-term indoor conditions is especially important.
Provide independent radon testing to support buyers, sellers, agents, and other parties who need documented results during real estate transactions.
Benefits of
Professional testing can identify elevated radon levels that would otherwise go unnoticed. Earlier awareness gives property owners the information needed to consider appropriate next steps before long-term exposure continues.
You receive documented radon measurements collected using established testing protocols. Clear results can support real estate transactions, property evaluations, recordkeeping, and other situations where reliable radon data is needed.
Testing shows how measured radon levels compare with Environmental Protection Agency (EPA) guidance. This information helps you determine whether additional testing, further evaluation, or radon mitigation should be considered.
Reliable testing replaces uncertainty with property-specific information. Homeowners, landlords, property managers, and other stakeholders can better understand indoor radon conditions and make informed decisions based on measured results.
Our technicians are certified by the National Radon Proficiency Program (NRPP) and National Radon Safety Board (NRSB), demonstrating verified training and ongoing compliance with professional requirements.
All testing follows EPA and ANSI/AARST standards to ensure proper device placement, test duration, and defensible results.
We use calibrated continuous radon monitors that collect detailed, time-weighted data rather than single snapshot readings.
You receive clear, documented radon reports with results and guidance aligned with the EPA 4.0 pCi/L action level.
