Caring for Your Radon Mitigation System Long After Inspection Day

Buying a home understandably puts radon hazards at the forefront, with professional inspection key to identify issues needing remedy before move-in. But what happens several months or years later when radon testing day is but a distant memory? Don’t let time breed false confidence. Proper ongoing mitigation system care remains vital to homeowner health and safety.

Let’s review smart steps for maintaining your home’s radon reduction network long after the inspector leaves.

Revisit Your Inspection Report
Even if your inspection uncovered no major problems, keep your detailed report accessible for reference. Periodically review the findings, room radon level measurements, and any minor recommendations made. This renews awareness of your home’s radon risk profile and prior state of the mitigation system. Use the baseline data to monitor for changes.

Conduct Routine Re-Testing
The EPA strongly advises retesting indoor radon levels every two years minimum, even in mitigated homes. Seasonal changes, shifting soils, or minute foundation cracks can alter radon seepage risks over time. While systems are designed to withstand variations, the only way to know levels remain safe is to regularly retest using short-term radon detection kits. Consistent low test results, on par with your original inspection’s findings, indicate your system still effectively reduces radon.

Install Permanent Radon Monitors
For maximum ongoing awareness, install discrete long-term radon monitors or detectors in your most at-risk lower home levels. These devices constantly sample air to identify abnormal concentration spikes, alerting you if radon suddenly breaches acceptable levels between periodic short-term testing. Today’s monitors are wi-fi enabled to send instant smartphone warnings of surges for quick intervention.

Keep Detailed Maintenance Records
Document any maintenance, repairs, upgrades, or changes to your radon reduction system over the years of homeownership. Log the date and details of tasks like checking or replacing filters, sealing minor foundation cracks, clearing ventilation pipe blockages, installing monitors or detectors, and retesting data. Thorough records help identify when issues emerged for diagnostic insight.

Maintain Proper House Pressurization\
Ideal home air pressure slightly exceeds outdoor pressure through well-balanced ventilation. This differential helps minimize radon entry. Have an HVAC professional assess house pressurization annually to ensure proper airflow balance between your home’s exhaust fans, fireplace, dryer, radon mitigation fan and fresh air intake. Imbalances strain the mitigation system.

Monitor the Mitigation Fan
A continuously running fan forms the active heart of most mitigation networks. Visually check your radon fan every few months for any concerning noises like rattling indicating pending failure. Test its suction flow periodically to ensure optimal radon gas removal from beneath the foundation. Replace filters as advised. Keep the fan outlet clear of debris, snow, or insect nests that could impede venting.

Watch for Renovation Effects
Home renovations and additions that disturb the foundation or alter airflow can increase radon risks over time. After any significant renovations, retest indoor radon levels to verify the mitigation system still keeps pace. Major projects may necessitate expanding or upgrading the radon reduction network with professional guidance.

Address Small Issues Promptly
During periodic self-inspections, carefully check pipes, fittings and seals for any new gaps or cracks that could allow radon gas to bypass your mitigation system. Seal and repair minor deteriorations immediately to prevent enlargement. A flexible sealant like caulk works for small pipe or fitting cracks, while expansive foam spray seals larger foundation fractures.

When inspection day long passes, don’t let radon vigilance fade. Protect those under your roof through conscientious lifelong care for your invaluable radon mitigation system. Consistent maintenance and retesting preserves your family’s essential defenses against this invisible home health hazard.
