What Homebuyers Need to Know About Radon in Portland
When purchasing a home in Portland, there are a lot of factors to consider: location, price, size, and condition. But there’s one crucial aspect that many buyers overlook—radon. Radon is a naturally occurring gas that can seep into homes, posing potential health risks to occupants. As a homebuyer in Portland, understanding what radon is, how it impacts your home purchase, and what you can do about it is key to making an informed decision.
What Is Radon?
Radon is an odorless, colorless, and tasteless radioactive gas that forms when uranium in soil, rock, and water breaks down. It can enter homes through cracks in the foundation, gaps around pipes, or even through the well water. While radon is present outdoors at low levels that are typically harmless, it can accumulate to dangerous levels indoors—especially in basements or homes built on porous soil.
Prolonged exposure to elevated radon levels is a significant health concern. According to the Environmental Protection Agency (EPA), radon is the second leading cause of lung cancer in the United States, responsible for around 21,000 deaths each year. This makes radon a crucial factor to consider when buying a home, especially if it has not been tested.
Why Is Radon Testing Important for Portland Homebuyers?
Portland, like much of the Pacific Northwest, has areas where radon is more prevalent due to the geology of the region. While radon levels can vary greatly from one home to another—even within the same neighborhood—it’s not uncommon to find elevated radon levels in Portland homes.
For homebuyers, testing for radon should be a standard part of the home inspection process. Radon levels are measured in picocuries per liter (pCi/L), and the EPA recommends taking action if levels are at or above 4.0 pCi/L. If a home tests above this threshold, mitigation is necessary to reduce radon levels and protect the health of future occupants.
How Radon Testing Works
Radon testing is a straightforward process, but it’s essential to have it done by a qualified professional. There are two main types of radon tests: short-term tests and long-term tests.
Short-term tests typically last 2 to 7 days and provide a snapshot of the radon levels in the home. These are the most common during the home-buying process since results are needed quickly before closing.
Long-term tests run for 90 days or more and give a more accurate average of radon levels over time. While these are ideal for long-term monitoring, they aren’t usually feasible during a real estate transaction due to time constraints.
Testing devices are placed in the lowest level of the home that is frequently used, such as a finished basement or living area. After the test period is complete, the radon levels are analyzed, and if high levels are detected, the buyer can negotiate with the seller to address the issue before finalizing the purchase.
Radon Mitigation: What Homebuyers Need to Know
If a home you’re considering purchasing tests positive for elevated radon levels, it’s important to know that this isn’t a dealbreaker. Radon mitigation systems are effective, affordable, and relatively easy to install. In fact, it’s common for buyers and sellers to negotiate the installation of a mitigation system as part of the home sale.
A radon mitigation system typically involves the following:
Sub-Slab Depressurization: This is the most common radon reduction method. It involves installing a vent pipe system and fan that draws radon from beneath the house and releases it safely outside, preventing it from entering the living space.
Sealing Cracks: Sealing foundation cracks and openings can reduce the flow of radon into the home, although it’s often used as a supplemental measure alongside active mitigation systems.
Ventilation: Increasing the home’s ventilation can also help reduce radon levels, but this method is less effective than a full mitigation system.
The cost of radon mitigation in Portland typically ranges between $1,200 and $2,500, depending on the size of the home and the complexity of the system. Many homebuyers successfully negotiate for the seller to cover some or all of this cost during the transaction process.
Radon’s Impact on Home Value
Radon issues can be a concern for potential buyers, especially if high levels are discovered during an inspection. However, installing a radon mitigation system can actually add value to a home. Homes with a system already in place offer peace of mind to future buyers, knowing that the radon issue has been addressed.
For sellers, it’s wise to test and, if necessary, mitigate radon levels before listing a home. This proactive approach can prevent last-minute negotiations or delays in the sale process.
Radon and Portland’s Real Estate Market
In Portland, where radon is a known issue in certain areas, having knowledge of the gas and how to address it is essential for both buyers and sellers. Testing for radon is not required by law in Oregon, but it is highly recommended as part of the due diligence process during a home purchase. Some Portland neighborhoods are more prone to higher radon levels than others, but because radon distribution is highly variable, every home should be tested regardless of location.
As awareness of radon increases, many buyers are making radon testing a non-negotiable part of their inspection. Portland real estate professionals are well-versed in this issue and can guide you through the testing and mitigation process, ensuring that your health and safety are prioritized.
Final Thoughts: Don’t Skip Radon Testing
Radon may not be top of mind for most homebuyers, but it plays a critical role in ensuring your new home is a safe and healthy place to live. Testing for radon is a simple and cost-effective way to avoid potential health risks and gives you peace of mind about your investment.
