Testing Services
Extinction Radon has some of the most advanced and reliable testing devices and methods in the industry. Within the last 15 years, many improvements and testing methods have been tried and developed in order to best determine indoor radon exposures. We use only the best processes and approved measurement devices that determine either the radon potential over a short period of time, or an average of the radon exposure over a longer period of time. Radon Potential: This is the short-term test mentioned above. This test typically lasts anywhere from 2-5 days and we conduct this test under closed building conditions. These closed conditions usually start 12 hours prior to the test and of course remain closed throughout the duration of the test. Our typical procedure is that the testing device is deployed at the lowest level of the home. This test is most commonly used during the resale of a home. Occupant Exposure: This is the long-term test mentioned above. We conduct this test for at least 91 days, but in some cases, the testing may even take up to one year. Because of the length of testing time needed, we conduct this test under normal lived-in conditions without a special closed building environment. Typically, we deploy the device at the lowest occupied level of home. This method is commonly used outside of real estate transactions. However, it is sometimes used at the basis of an escrow fund release, especially if a short-term test has shown results between 4 and 10 pCi/L. |
Installed Mitigation Systems
Our radon mitigation process works by connecting a system that will draw the radon infected soil gas from under the foundation of the structure and then releasing it outside of the structure all together. We of course make sure that this harmful gas is released far enough away from any openings or windows that would allow it to reenter the building or home. Our mitigation systems generally involve plastic piping, linked to the soil, using a precisely placed hole in the basement through what is known as a sump lid connection. In a crawl space situation, we can usually draw access from beneath plastic sheeting. These crawlspace systems may be more costly because our installer will need to put in high density plastic sheeting over the soil and seal this sheeting to the walls. However, most of our customers find that the added benefit of moisture reduction in the crawlspace, in addition to the radon reduction, is worth the extra cost. After the initial piping is installed, we then attach a quiet, continuously operating fan that releases the radon outside of the building or home. Our professional, certified, and fully insured installers are prepared for all situations. Many inexperienced installers will find it difficult to install a system in a home with more than one foundation. However, our experienced mitigation professionals are trained and certified to connect multiple systems together so that only one fan system is required. |
