If a long-term test or several short-term tests show a high reading for radon, there are several actions you can take as a homeowner. One of the most effective is to hire a contractor to resolve the issue. This may cost anywhere from $700 to $2,500 depending on the source of the problem and the size of your home.
For homeowners who prefer to be more informed before tackling a problem, even when hiring professionals, consider reading the EPA’s Consumer’s Guide to Radon Reduction. Many homeowners successfully used this information to lessen their radon problem. Even so, it is always best to turn to professional contractors for a permanent solution.
