For example, a retrofit system directed outside the house can reduce radon rather well, but it might not be as aesthetically pleasing as one transmitted with an interior wardrobe. The system style is a feature of the building and construction of the home, rather than the radon focus in the home. A residence with greater than one foundation can present challenges to collecting the soil gas from under all parts of the structure. Nonetheless, experienced mitigation service providers can sometimes connect several systems together to make sure that only one follower system is required.
