High Radon? Don't Panic: Your Guide to a Stress-Free Real Estate Closing

The good news is in: Your offer was accepted!

After weeks or months of searching, countless property visits, and coordinating with your lender, you finally found the perfect house. Congratulations! Now you’re in the inspection period — a vital stage for uncovering any potential issues.

You’ve reviewed the reports and discovered that the radon levels are high. Stop, take a breath, and don’t let this be a deal-breaker.

Should High Radon Levels Be a Deal Breaker? Absolutely Not.

High radon levels during a home inspection are a common issue, especially in regions like Louisville and Southern Indiana. The good news? Reducing them is usually straightforward — and can often be completed in less than a day.

Cost Reality: The cost typically ranges from $1,000 to $3,000, with the average professional radon mitigation systemcosting around $1,400.

Who Should Pay for the Mitigation System?

This is where the negotiation begins. The discussion about who will cover the installation of the radon reduction systemtakes place during the resolution period of the real estate transaction.

  • Seller Pays: Sometimes the seller will pay for and coordinate the installation directly.

  • Seller Offers Credit: Other times, they may offer the buyer funds (a credit) to handle it after closing.

Our Recommendation for Buyers

We strongly recommend that the buyer handles the radon mitigation. Why?

  • Quality Control: You ensure that corners aren’t cut and that the highest quality methods and materials are used.

  • Family Focus: You can make long-term decisions with your individual family’s health and safety in mind.

7 Key Considerations for a Quality Radon Mitigation System

Odds are many of your neighbors have a system installed and you never noticed.

Protect Your Family with a Proven Radon Mitigation Method

If you or the seller moves forward with mitigation, keep these factors top of mind:

  1. Cost vs. Quality
    Be wary of cheap mitigation methods. Costs vary based on the home’s foundation (crawl space, slab, sump pump). A cheaper installation could lead to issues later. A basic system might not address all necessary areas, such as sealing a sump-lid or caulking floor cracks — all of which can substantially reduce long-term exposure.

  2. Aesthetics Matter
    As the future homeowner, you will want some input on the placement and appearance of the exterior mitigation system.

  3. Hire a Certified Expert
    Ensure the work is done by a certified professional. Look for certifications from the NRPPAARST, or other accredited organizations. Installation must meet EPA radon standards.

  4. Meet the Deadline
    Confirm that the mitigation company can finish the job to meet your closing deadline.

  5. Get a Warranty
    Your system should come with a warranty, typically for the fan (around five years). The installer should also provide documentation on system operations and maintenance.

  6. The Crucial Retest
    After installation, it is vital to retest your home for radon levels. This step is often overlooked! The installer may conduct the retest, or you can use a third-party service to ensure impartiality. Make sure it’s done.

  7. Functionality Check
    Just because a system is present doesn’t mean it’s reducing radon levels effectively. A professional retest confirms the system is functional and compliant.
