On this page: Techniques for reducing radon are discussed in EPA's Consumer's Guide to Radon Reduction. As with any other household appliance, there are costs associated with the operation of a radon-reduction system.
You should also test your home again after it is fixed to be sure that radon levels have been reduced. If your living patterns change and you begin occupying a lower level of your home (such as a basement), you should retest your home on that level.
In addition, it is a good idea to retest your home sometime in the future to be sure radon levels remain low.
Radon and Home Renovations - If you are planning any major renovations, such as converting an unfinished basement area into living space, it is especially important to test the area before you begin.
If your test results indicate an elevated radon level, radon-resistant techniques can be inexpensively included as part of the renovation. Major renovations can change the level of radon in any home. Test again after the work is completed.
