Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:129 EcoTip: Fixing radon problems isn’t a nightmare, provided you do your homework and understand what your doing. EPA has excellent guidance information on how to do-it-yourself as well as choosing a contractor to do it for you.

The diagram is a composite view of several mitigation options.  The typical mitigation system usually has only one pipe penetration through the basement floor; the pipe may also be installed on the outside of the house.

 Additional Information

EPA states:

Since there is no known safe level of radon, there can always be some risk. But the risk can be reduced by lowering the radon level in your home.

There are several proven methods to reduce radon in your home, but the one primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside.  This system, known as a soil suction radon reduction system, does not require major changes to your home.  Sealing foundation cracks and other openings makes this kind of system more effective and cost-efficient.  Similar systems can also be installed in houses with crawl spaces. Radon contractors can use other methods that may also work in your home. The right system depends on the design of your home and other factors.

The cost of reducing radon in your home depends on how your home was built and the extent of the radon problem. Most homes can be fixed for about the same cost as other common home repairs. The average house costs about $1,200 for a contractor to fix, although this can range from about $800 to about $2,500.  The cost is much less if a passive system was installed during construction.
