Before closing on a house, it’s good to know as much about it as possible. That’s why many different kinds of inspections are important. Those inspections can help you make sure the structure is sound and is worth your investment, but they also should tell you that this house can be a healthy place to live.
Houses of a certain age may have lead paint or pipes or asbestos materials. The mere presence of those materials doesn’t necessarily mean they’re dangerous. Inspections for those materials can help you decide whether they need attention and how to live safely with them in your house. Your local Association of Realtors® can help you find qualified inspectors for lead and asbestos.
One inspection that isn’t as obvious is testing for radon gas. It’s invisible, doesn’t smell, and you can’t know it’s there unless you test. Unlike lead and asbestos, it doesn’t matter how old the house is, whether it’s a walk-out basement or slab, or even whether it’s been tested before. Any house can have elevated levels of radon, even in neighborhoods where no other houses have elevated radon.
Radon is the number one cause of lung-cancer in non-smokers. If you smoke, radon makes your risk of lung cancer greater. With the increased use of nuclear medicines and diagnostics, the added radioactive dose of radon increases the risk even more. The U.S. Environmental Protection Agency has set 4 pCi/L (picoCuries per liter of air) as the “action level.” At 4 and above, EPA says you should bring the level down.
In September 2009, the World Health Organization suggested we lower our radon exposure to 2.7 pCi/L. Countries all over the world are beginning to implement this suggestion. If you decide your house should have levels of radon lower than the EPA action level, make sure you work with your Realtor® to specify that in your contract offer.
A straight-forward test can tell you if your house has elevated radon. Certified testers are available and can be found by accessing your state’s radon website or through your Association of Realtors® professional. A nationally trained and certified radon tester is especially important for testing radon during a real estate transaction to ensure the test is properly conducted by an objective third party.
If elevated levels of radon are found, a radon mitigation system can be readily installed, again, by a certified radon mitigation professional [link to Find a Contractor]. A properly installed system can reduce your radon concentration and give you better indoor air quality. Because the system reduces the humidity that enters your home from the ground, you will have a drier, better smelling, more comfortable basement that you and your family can feel comfortable living in.
Including radon testing and other environmental tests in your home purchase agreement can give you the confidence that the home you’re buying will be a healthy place to live and help ensure a sound real estate investment.
