How To Fix

Ventilation
The easiest way to reduce radon is to keep all the windows of the home open, especially all of the basement windows. Keeping basement windows open helps to minimize the negative pressure within the lower part of the home and helps to dilute the radon. For this to work though, the windows need to be kept open all the time. If not, radon returns to full strength in as little as 6 hours. The problem with this method is that it takes a lot of fresh air to dilute radon. In the summer and wintertime, this can be very uncomfortable and greatly increase your utility bills. If you’d like to use a window fan to increase airflow, make sure that the fan is blowing air from outside into the basement, not the other way around. If the fan is blowing air out of the basement, it can increase the negative pressure that draws radon into your home and your radon level can go up instead of down.
Sealing Work

Radon Removal Systems
The most effective way to get rid of radon is to install a removal system that draws the radon out of the soil before it even has an opportunity to enter the house. These systems are called "Sub Slab Depressurization Systems" or "Active Soil Depressurization Systems". These systems operate by using a piping and fan system that depressurizes the soil that surrounds the home. This in effect reverses the pressure differential between the soil and the lower portion of your home. You'll still have the same pressures within your house that you've always had and never noticed, but the radon will be vented safely outside so that it can dissipate harmlessly into the atmosphere. It doesn’t take much of a pressure differential to draw radon into a home, and it doesn’t take a lot of pressure to draw it out.


What Type Of System Is Best For My House?
A radon specialist can help to determine which type of system is best for you. Your home may need a combination of types and may also need sealing work as part of the system. A radon mitigator will usually perform diagnostics before any type of system is installed to determine what is best for your particular home. Diagnostics normally consists of drilling a few small ½” holes through the concrete that will later be plugged and sealed. These test holes allow the specialist to determine where the radon is coming from, types of soil and where the suction point(s) need to be for your particular home. Homes with crawlspaces, or homes built on ground level all require different approaches, but when designed and installed properly, systems can reduce radon levels by up to 99%. In some cases these systems can bring your radon level down to the same as the outside air!
Benefits Of A Radon Removal System


How To Choose A Radon Specialist
In most States, both radon testers and radon mitigators are required to complete an approved training course and pass a written exam. If your State requires certification, make sure the company you hire has been properly trained and certified.
Choose a radon specialist like you would a teacher, lawyer or doctor. You want the best your family can afford. There is no substitute for experience so select a mitigator with the most experience you can find in your area. It's also smart to look for the one that offers the best guarantee and longest warranty. Try to find a mitigator that will give you a firm price not an open ended estimate. It's also nice to find one that provides a free test after the work is completed. Just like any type of service, there are a wide variety of companies to choose from and price isn’t always the best judge of quality. The best mitigators won’t just look at your house and tell you what is needed. They will conduct diagnostics first to determine what is best for your particular style of house and soil characteristics. After diagnostics, they should be able to give you several options on how the system is installed and let you choose whichever you prefer. If the person you choose doesn’t perform diagnostics, you probably picked the wrong guy. Usually, the better the mitigator you hire, the lower your final radon level will be.
Building A New Home?
Be sure to ask your builder to have a "passive" radon system installed during construction. The required piping can be hidden in the walls, vented out of the roof and tied into the drainage tiling system below your basement floor. If it tests high for radon after the home is completed, all you need to do is add the fan!
