The Hidden Radon Danger That Could Derail Your Real Estate Deal
Imagine this: You’ve finally found your dream home. The location is perfect, the layout is just what you’ve been looking for, and the price is within budget. Everything seems to be going smoothly—until a simple radon test threatens to derail the entire deal. This is the hidden radon danger that could derail your real estate deal. Radon, a radioactive gas that seeps into homes from the ground, is one of the most overlooked hazards in Canadian real estate. It’s invisible, odorless, and tasteless, but it’s also the leading cause of lung cancer in non-smokers, according to Health Canada. Although things are slowly changing, many homebuyers, sellers, and even real estate agents fail to account for radon, which can lead to costly last-minute surprises, delayed closings, and even deals falling apart entirely. If you’re in the market for a home—or planning to sell one—radon should be a top priority. This guide will cover everything you need to know about radon, how it can impact real estate transactions, and what you can do to protect yourself.
What is Radon and Why is it a Problem?
Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil, rock, and water. It moves up through the ground and can enter homes through cracks in foundations, gaps around pipes, or even well water. Once inside, radon accumulates and can reach dangerous levels. Long-term exposure to radon is the second leading cause of lung cancer, after smoking. The risk increases significantly in homes with high radon levels, yet most people remain unaware of the problem until they test their home.
Many people assume that radon is only a concern for older homes or properties built in specific geographic regions. However, radon’s unpredictability is what makes it so dangerous—two houses on the same street can have drastically different radon levels. This means that even if a neighbor’s home tested low, your home could still have dangerously high radon levels. Seasonal variations also play a role, with radon levels typically being highest in winter when homes are sealed tight, trapping the gas inside.
Health Canada has set an action level of 200 Bq/m³, meaning that any home testing above this level should have radon mitigation installed. Radon exposure is a long-term health risk rather than an immediate danger, but the consequences can be severe. Given that lung cancer caused by radon is entirely preventable with proper mitigation, it is crucial for homebuyers to take radon seriously.
How Radon Can Derail a Home Purchase
Real estate transactions can be complicated, and radon has the potential to add unexpected hurdles. Many homebuyers request a radon test as part of the inspection process, and if the test reveals high radon levels, the buyer may have second thoughts about moving forward with the purchase. This can create significant delays, force renegotiations, or even cause deals to fall through entirely.
Buyers who discover high radon levels in their prospective home typically have three options: request that the seller pay for mitigation before closing, negotiate a lower sale price to offset future mitigation costs, or walk away from the deal entirely. If the seller refuses to take action, the buyer may be unwilling to assume the financial and health risks associated with high radon levels, especially if they are unfamiliar with the mitigation process.
The presence of radon can also impact financing and home insurance options. Some mortgage lenders require radon testing before approving loans, and if high radon levels are detected, securing financing can become more difficult. Likewise, certain insurance providers may have policies regarding radon that affect coverage eligibility. Without proper testing and mitigation, these additional complications can turn what seemed like a straightforward home purchase into a frustrating ordeal.
Beyond financial and logistical concerns, radon also has legal implications for sellers. In some regions, sellers are legally required to disclose radon levels to potential buyers. Even in areas where disclosure laws are not strictly enforced, failing to test and mitigate radon can leave sellers vulnerable to future legal action if buyers later experience health issues due to radon exposure. For both buyers and sellers, addressing radon concerns early in the transaction process is the best way to avoid costly surprises.
What Homebuyers Should Do Before Making an Offer
If you’re in the market for a new home, taking proactive steps to address radon concerns can save you time, money, and stress. The first step is to ask the seller for any existing radon test results. Some homeowners have already conducted tests, and reviewing the results can provide valuable insight into potential radon risks. However, it is essential to verify that the test was conducted by a qualified C-NRPP professional and followed Health Canada’s guidelines. A test performed improperly or in a non-representative area of the home may not provide an accurate reading.
Even if the seller provides test results, conducting your own radon test is a smart move. The most accurate way to measure radon is through a long-term test, which lasts 90 days or more. If time constraints make this impractical, a short-term test (2-7 days) can provide a quick estimate. Professional testing services offer the most reliable results, but homeowners can also use approved do-it-yourself radon test kits. If test results indicate radon levels above 200 Bq/m³, you should factor in mitigation costs before finalizing your offer. Negotiating with the seller to cover the cost of mitigation or adjusting the purchase price accordingly can help ensure you are not left with unexpected expenses after moving in.
What Sellers Can Do to Avoid Radon-Related Roadblocks
For sellers, investing in radon testing and mitigation before listing a property can prevent complications later in the sales process. Buyers who encounter high radon levels may hesitate to proceed with the purchase or request price reductions and remediation before closing. Conducting a radon test before putting the home on the market allows sellers to address any concerns ahead of time.
If a test reveals elevated radon levels, installing a mitigation system can make the home more attractive to buyers. A properly mitigated home not only reassures potential buyers but may also justify a higher asking price. Sellers who can provide documentation of successful radon mitigation demonstrate responsibility and transparency, fostering trust and reducing the likelihood of disputes during negotiations.
Additionally, being upfront about radon levels and mitigation efforts can help sellers comply with disclosure laws and avoid potential legal consequences. Even if local regulations do not require radon disclosure, failing to address radon issues may lead to liability claims if buyers later experience health problems related to radon exposure. By proactively managing radon concerns, sellers can ensure a smoother transaction and attract more confident buyers.
Take Action to Protect Your Investment
Radon is an invisible threat that can have real consequences for homebuyers and sellers. Whether you're purchasing a home or putting one on the market, addressing radon concerns early can save you time, money, and unnecessary stress. Buyers should insist on radon testing before closing a deal, while sellers can avoid roadblocks by testing and mitigating radon in advance. A home with a properly installed mitigation system is not only safer but also more appealing to potential buyers.
By taking proactive steps, you can ensure that radon doesn’t become an unexpected obstacle in your real estate transaction. Don’t let this hidden danger derail your dream home—test for radon, mitigate if necessary, and move forward with confidence.
