10 pCi/L Basement Radon Levels Lead Homeowner to Choose ERV System

The homeowner became concerned about radon after noticing more mitigation systems appearing throughout the neighborhood and town. A detector borrowed from the local library showed levels around 3–4 pCi/L on the main level and approximately 10 pCi/L in the basement, highlighting the importance of addressing radon in the lower portion of the home. The property also includes a large crawl space addition built about 30 years ago, adding complexity to the project. Although the homeowner was concerned about the appearance of a traditional depressurization system, they chose an ERV as part of their indoor air quality solution. The project provides a practical approach to improving ventilation while addressing concerns about the home's indoor environment.
