Efficient Mount Olivet Radon Mitigation

Proper fan placement is critical to both system safety and performance. According to EPA guidelines, the fan should always be installed above the living area - such as in the attic, garage, or exterior - so that any radon leaking from the fan housing exits the home rather than entering occupied spaces. Placing the fan in a basement or crawl space connected to living areas can create a safety hazard if the fan housing cracks or seals fail over time. Additionally, fans placed too far from the suction point can experience pressure loss due to long pipe runs, which may reduce overall system effectiveness.

In most cases, a straightforward fan replacement can be completed by a professional radon contractor in one to two hours. The process involves cutting the existing fan out of the pipe, installing the new fan with proper couplings and sealants, restoring electrical connections, and verifying system suction with a manometer. If additional repairs are needed - like resealing pipe joints, addressing clogs, or modifying the pipe run - the job may take longer. Homeowners should plan to be available during the service call so the contractor can review test results and answer any questions about the new fan installation.

A fan that is running but failing to reduce radon levels suggests the system is not generating adequate negative pressure beneath the foundation, which can have several causes. The fan may have lost suction capacity due to motor wear, or it may be undersized for your specific soil conditions and foundation design. New foundation cracks, open sump pits, or changes to the home's structure can also create pathways for radon to bypass the system entirely. A certified contractor should perform a pressure diagnostic and sub-slab evaluation to identify the specific cause before recommending a solution.
