Radon mitigation typically requires a site evaluation to determine the best method for reducing radon levels in a building. If someone is unwilling or unable to come to your house to perform a site evaluation, there are still some steps you can take to mitigate radon.
One option is to purchase a do-it-yourself radon testing kit, which can be ordered online or purchased at many home improvement stores. These kits usually involve placing a small device in the building for a period of time, and then sending the device to a laboratory for analysis. The results can give you an indication of whether radon is present, and at what levels.
If the results of a do-it-yourself test suggest that radon levels are high, there are also some do-it-yourself mitigation methods that can be attempted. These methods typically involve sealing any cracks or openings in the foundation and installing a ventilation system to circulate air and reduce radon levels. However, it is important to note that do-it-yourself mitigation methods may not be as effective as those performed by a professional, and it is still recommended to have a professional evaluation if possible.
Overall, while a site evaluation performed by a professional is the ideal way to determine the best course of action for mitigating radon, there are still options available for those who are unable or unwilling to have a professional evaluation.
