A variety of methods are used to reduce radon in your home.  In some cases sealing cracks in floors and walls may help to reduce radon.  In other cases, simple systems using pipes and fans may be used to reduce radon.  Such systems are called "sub-slab depressurization", and do not require major changes in your home.  These systems remove radon gas from below the concrete floor and the foundation before it can enter the home.  The right system depends on the design of your home and other factors.

Ways to reduce radon in your home are discussed in EPA's "Consumer's Guide to Radon Reduction".  You can get a copy from the VDH Radiological Health Program.

The cost of making repairs to reduce radon depends on how your home was built and the extent of the radon problem.  Most homes ca be fixed for about the same cost as other common home repairs like painting or having a new hot water heater installed.  The average house costs about $1,200 for a contractor to fix, although this can range from about $500 to about $2,500.

Lowering high radon levels requires technical knowledge and special skills.  You should use a contractor who is trained to fix radon problems. Virginia State Law requires radon contractors who install radon reduction systems to be listed with either the National Radon Profiency Program (NRPP): , or the National Radon Safety Board (NRSB):
