Radon is a cancer-causing gas that can lead to serious illness and even death. It is found across the United States, with elevated levels along the southern coast, from California to Florida. It is colorless and odorless, but you can test the radon levels in your home by using a radon testing kit, available for around $40. If you find out that your home has high radon levels, it can not only be scary, but also frustrating. Is there anything that can be done to lower the radon inside of your home without calling a professional? Not only is radon ventilation a good idea, it’s also relatively easy to accomplish.

Natural Radon Ventilation

One of the easiest ways to ventilate your home is to use the natural ventilation resources that you already have. Windows, doors and vents all act to circulate the air inside of your house. To ensure that radon ventilation is executed properly, begin with the lowest level of your home (first floor or basement). Open up all of the windows, doors and vents on the lowest level of your home for at least three hours. This will allow the radon inside of your home to exit through windows, doors and vents by mixing with outdoor air. While this type of radon ventilation will help to reduce the amount of radon inside of your home, further steps are necessary to prevent the return of radon.

Fan and Heat Ventilators

By placing a powerful fan at the top of your basement stairs, you can blow air into your basement. This will, in turn, create an immense amount of pressure inside of your basement. Once enough pressure has accumulated, this wall of pressure will prevent radon from entering your living area through your basement. While going through the aforementioned steps, make sure that all the windows and doors inside of your basement are shut tightly.

Finally, you may want to consider having a heat recovery ventilator (HRV) installed in your home. This type of radon ventilation works to increase aeration, which ultimately lowers the amount of radon inside of your home. Generally, HRVs are most effective when they are placed inside of a basement area, though they can also be placed inside of the main living area.

When to Call the Experts

Radon ventilation can be achieved by any of the methods mentioned above. Still, radon is not a type of gas that you want to take chances with. If the radon levels inside of your home do not decrease following any of the radon ventilation methods listed in this article, then you should call a professional contractor.

Since every home is different, reducing radon inside of your home may be more difficult than you think. A professional contractor can determine the best course of action based upon your home’s structure. Once radon has been professionally eliminated from your home, the chances of this gas returning are rather slim.
