Our Services
Initial Radon Consultation
A certified radon professional will meet with you in your home to provide a personalized assessment of your property's radon risk and answer any questions you may have about radon exposure (click “+” sign to see more details).
-
During the consultation, we will :
Explain what radon is, where it comes from, and how it can affect indoor air quality and long-term health.
Discuss how radon enters homes through the natural movement of soil gases and identify common entry pathways, including foundation cracks, utility penetrations, sump pits, floor-wall joints, crawlspaces, and other openings.
Conduct a visual assessment of your basement, crawlspace, and other relevant areas to identify potential radon entry points and factors that may influence radon levels within the home.
Review how home characteristics, weather conditions, HVAC operation, occupancy patterns, and seasonal changes can affect radon concentrations.
Explain the differences between short-term testing and long-term monitoring, including the advantages and limitations of each approach.
Demonstrate why long-term monitoring provides the most complete picture of a home's radon exposure by capturing the natural fluctuations that occur daily, weekly, and seasonally.
Long-Term Radon Monitoring
Our Long-Term Continuous Radon Monitoring service provides homeowners with the most accurate and comprehensive understanding of their home's radon levels. Rather than relying on a single short-term test that captures only a brief snapshot in time, continuous monitoring tracks radon concentrations around the clock, revealing trends and fluctuations that occur throughout the year.
-
Radon levels are constantly changing. Weather patterns, barometric pressure, temperature differences, wind conditions, precipitation, HVAC operation, occupancy habits, and seasonal changes can all cause radon concentrations to rise and fall—sometimes dramatically within hours or days. Because of these fluctuations, a short-term test may overestimate or underestimate your home's typical radon exposure.
Our monitoring program uses professional-grade continuous radon monitors to collect measurements 24 hours a day, providing ongoing insight into your indoor radon environment. This data allows homeowners to make informed decisions based on actual long-term exposure rather than a limited testing window.
-
Provides a More Accurate Assessment
Captures daily, weekly, and seasonal radon fluctuations.
Reduces the likelihood of making decisions based on unusually high or low short-term readings.
Produces a more representative picture of your home's typical radon levels.
Measures Actual Exposure Over Time
Health risks associated with radon are linked to long-term exposure, not isolated readings.
Long-term monitoring better reflects the conditions occupants experience throughout the year.
Identifies Trends and Changes
Detects gradual increases or decreases in radon levels.
Helps identify the effects of weather events, home renovations, HVAC changes, and occupancy patterns.
Provides ongoing verification that radon levels remain acceptable.
Supports Better Mitigation Decisions
Helps homeowners determine whether mitigation is warranted.
Provides confidence when evaluating the effectiveness of existing radon reduction systems.
Reduces the risk of unnecessary mitigation based on temporary spikes.
Continuous Peace of Mind
Eliminates the uncertainty associated with one-time testing.
Allows homeowners to monitor radon conditions year-round.
Provides ongoing awareness of changes that could affect indoor air quality.
What Clients Receive
Professional installation and setup of a continuous radon monitor.
Ongoing collection of radon measurements 24 hours per day.
Access to historical radon data and trend analysis.
Periodic summaries highlighting average levels, peak readings, and long-term trends.
Guidance from a certified radon professional regarding interpretation of results and potential next steps.
Ideal For
Homeowners seeking the most accurate understanding of radon levels.
Families concerned about long-term indoor air quality.
Homes with previous elevated radon results.
Properties with radon mitigation systems requiring ongoing verification.
Real estate buyers and sellers who want data beyond a short-term test.
Because radon levels naturally fluctuate over time, the most reliable way to understand a home's true radon risk is through continuous long-term monitoring. By measuring radon where you live, day after day and season after season, you gain the information needed to make confident, informed decisions about protecting your family's health.
Monthly Reporting & Analysis
As part of our Long-Term Continuous Radon Monitoring service, clients receive a comprehensive monthly report that transforms thousands of individual radon measurements into clear, actionable information. Rather than simply providing a single radon reading, our reports help homeowners understand how radon levels have changed over time and what those changes may mean for their home's indoor air quality.

-
Each monthly report includes:
Monthly Average Radon Level – A summary of the home's average radon concentration for the reporting period.
Daily and Weekly Trends – Analysis of how radon levels changed throughout the month, helping identify recurring patterns and fluctuations.
Highest and Lowest Recorded Levels – Identification of peak and minimum readings observed during the reporting period.
Historical Comparison – Comparison with previous monitoring periods to identify increases, decreases, or long-term trends.
Graphical Timeline Data – Easy-to-understand charts illustrating radon activity over time.
Exposure Insights – Interpretation of the data in the context of long-term radon exposure and established action levels.
Professional Review – Analysis and commentary from a certified radon professional when significant trends or concerns are identified.
Why Monthly Reporting Matters
Radon levels can vary significantly from day to day and season to season. Monthly reporting allows homeowners to move beyond isolated readings and gain a deeper understanding of their home's radon profile.
Benefits include:
Early identification of rising radon trends before they become a larger concern.
Verification that existing mitigation systems continue to perform effectively.
Documentation of radon conditions over time for personal records, real estate transactions, or future mitigation decisions.
Increased confidence that decisions are being based on long-term data rather than temporary fluctuations.
Clear, Actionable Information
Our goal is to make complex radon data easy to understand. Each report is designed to provide meaningful insights—not just numbers—so homeowners can confidently assess their indoor air quality and determine whether any additional action may be warranted.
With continuous monitoring and monthly reporting, you gain an ongoing view of your home's radon levels and the peace of mind that comes from understanding your long-term exposure throughout the year.

Contractor Evaluation and Referrals
Selecting the right mitigation contractor can have a significant impact on both system performance and long-term value. We maintain relationships with mitigation professionals who have established strong reputations for:
High-quality workmanship
Professional installation practices
Competitive and economical pricing
Responsive customer service
Proven mitigation performance
Compliance with industry standards and best practices
When requested, we can provide referrals to mitigation professionals who meet these criteria and serve your geographic area.
Post-Mitigation VerificationA successful mitigation system should not simply be installed—it should be verified. Following mitigation, we can assist with ongoing monitoring and analysis to help confirm that radon levels have been reduced and remain at acceptable levels over time.
Studies suggest long-term tests provide precise results in 96% of cases, while short-term tests can fail to predict accurate outcomes up to 98% of the time.
