Getting test results showing your Raleigh home has radon levels at or above the EPA action level of 4.0 pCi/L is understandably concerning. However, high radon doesn’t mean your home is uninhabitable or that you made a bad investment. Radon problems are solvable, and professional radon mitigation can reduce levels dramatically, protecting your family’s health while preserving your home’s value. Knowing what steps to take immediately after discovering elevated radon helps you address the problem efficiently and effectively.
Don’t Panic, But Don’t Delay
First, understand that radon exposure is a long-term health risk, not an immediate emergency. Living in your home for a few more weeks while you arrange for mitigation won’t significantly increase your lifetime cancer risk. That said, don’t use this as an excuse to procrastinate. The sooner you implement mitigation, the sooner you reduce your family’s exposure to this carcinogen.
If you have young children or family members who spend significant time in lower levels of your home where radon concentrations are typically highest, consider having them spend more time on upper floors while you work on mitigation. Opening windows and increasing ventilation can provide temporary, modest reductions in radon levels, though this isn’t a long-term solution.
Verify Your Test Results
If you used a DIY test kit that showed elevated radon, verify the results with professional testing before investing in mitigation. DIY tests can sometimes produce false positives due to testing errors, contamination, or improper placement. Professional continuous radon monitors provide more accurate data and detailed reports that help mitigation specialists design appropriate systems.
If professional testing confirmed your elevated levels, you can move forward with confidence that mitigation is necessary. Keep your test results – you’ll need them when getting mitigation estimates and again for documentation if you sell your home in the future.
Research Certified Radon Mitigation Professionals
Radon mitigation isn’t a DIY project. Effective mitigation requires specialized knowledge of radon behavior, building science, and proper system design. Look for mitigation professionals who hold certification from the National Radon Proficiency Program (NRPP) or National Radon Safety Board (NRSB).
These certifications require extensive training and ongoing education to maintain. Certified professionals understand how to design systems that work with your home’s specific foundation type, construction characteristics, and radon levels. They also carry proper insurance and warranties that protect you if something goes wrong.
Ask potential mitigation contractors about their experience with homes similar to yours. A company that primarily works on slab foundations might not be the best choice if you have a crawl space home. Request references from recent customers and check online reviews to gauge the company’s reputation for quality work and customer service.
Get Multiple Estimates
Contact at least three certified radon mitigation companies for estimates. Each contractor should visit your home to assess the situation before providing a quote. Be wary of companies that offer estimates over the phone without inspecting your property – every home is different, and accurate estimates require on-site evaluation.
During the inspection, the mitigation professional should examine your foundation type, basement or crawl space conditions, existing mechanicals, and optimal locations for system components. They should explain their proposed approach, where the radon fan will be installed, how the piping will be routed, and what kind of warranty they provide.
Understand Different Mitigation Approaches
Most homes in Raleigh will be candidates for active soil depressurization – the most common and effective mitigation method. However, the specific variation of ASD depends on your foundation. Homes with basement or slab foundations typically use sub-slab depressurization, while crawl space homes need sub-membrane depressurization with proper crawl space sealing.
Some homes with unique characteristics might benefit from alternative approaches like drain tile suction or block wall suction. Trust your mitigation professional to recommend the system that’s most appropriate for your situation rather than insisting on a particular method you’ve read about online.
Plan for the Installation Process
Professional radon mitigation typically takes one day to complete, though complex installations might require two days. The process involves drilling through your foundation, installing PVC piping, mounting the radon fan, and routing the exhaust pipe above your roofline.
Contractors will need access to your basement or crawl space, exterior walls for pipe routing, and your attic or exterior wall for fan installation. Clear these areas beforehand and plan for some noise and temporary disruption. Most companies clean up thoroughly after installation, but expect some dust from drilling.
If you’re having your crawl space sealed as part of the mitigation, that portion of the work might take longer depending on the size and condition of the space. The contractor should explain the timeline clearly before work begins.
Post-Mitigation Testing Is Essential
After your mitigation system is installed and has been running for 24 hours to 30 days, you need post-mitigation testing to verify the system is working effectively. This testing should be performed by an independent tester, not the mitigation company, to ensure objective results.
The goal is to see radon levels reduced to below 4.0 pCi/L, and most professional systems achieve levels well below 2.0 pCi/L. If post-mitigation testing still shows elevated radon, the mitigation company should adjust the system at no additional charge – this is why warranties matter.
Document your post-mitigation test results and keep them with your home’s permanent records. These results demonstrate to future buyers that you identified and resolved the radon issue properly.
Maintain Your Radon System
Once installed, radon mitigation systems require minimal but important maintenance. The radon fan runs continuously, so check the system’s warning device monthly to ensure it’s operating. This is usually a simple visual indicator – a small tube with colored liquid or balls – that shows at a glance whether suction is being maintained.
Listen for unusual sounds from the fan that might indicate bearing wear or other mechanical problems. Most radon fans last 10-15 years before needing replacement, but monitoring the system helps you catch issues early.
Test your home’s radon levels annually even with a functioning mitigation system. This verifies the system continues working effectively and gives you peace of mind that your family remains protected.
Address Any Structural Issues
If your foundation has major cracks, gaps around utility penetrations, or other obvious defects that are allowing radon entry, address these as part of your mitigation plan. While sealing alone won’t eliminate radon problems, it supplements active mitigation and can improve system efficiency.
Your mitigation professional should include basic sealing of major entry points as part of the installation. For homes with significant structural issues, you might need to consult with a foundation specialist before or during mitigation.
Moving Forward with Confidence
High radon levels are concerning, but they’re not insurmountable. Professional mitigation transforms a home with dangerous radon exposure into a safe environment for your family. The investment in mitigation protects your most valuable asset – your family’s health – while preserving your home’s value for future sale.
