Radon Testing and Mitigation Project
When Madison B. contacted Inspection Plus Group about radon testing for her 1960s split-level home in Hyde Park, she was concerned about potential health risks to her young family. Like many Cincinnati homeowners, Madison had heard about radon risks but wasn’t sure what levels might be present in her home.
Initial Testing Process
Our certified inspectors placed continuous monitoring devices in her finished basement, where her children’s playroom was located. The 48-hour testing period revealed average radon levels of 6.2 pCi/L, significantly above the EPA’s recommended action level of 4.0 pCi/L.
Customized Mitigation Plan
After reviewing the test results with Madison, our team developed a mitigation strategy specifically for her home’s construction style. We identified key areas requiring attention:
- Multiple foundation entry points
- Complex split-level architecture
- Existing HVAC configuration
- Family’s routine home usage patterns
System Installation
Working around the family’s schedule, our team installed a complete mitigation system in one day. The installation included:
- Sub-slab depressurization system
- Premium-grade radon fan unit
- External ventilation piping
- Digital monitoring system
- Foundation sealing
Post-Installation Results
Follow-up testing after system installation showed radon levels had dropped to 1.3 pCi/L, well below the EPA’s action level.
“The Inspection Plus Group team made the entire process so smooth,” shares Madison. “From the initial testing to explaining our options and installing the system, they were professional, thorough, and considerate of our family’s needs. Most importantly, I can now rest easy knowing our home’s radon levels are safe for my family.”
