If this inspection fails to provide enough information, the contractor will need to perform diagnostic tests to help develop the best radon reduction system for your home. Your contractor will perform a visual inspection of your house and design a system that is suitable. Normal settling of your house opens new entry routes and reopens old ones.Īny information that you may have about the construction of your house could help your contractor choose the best system. It is difficult to identify and permanently seal the places where radon is entering. The EPA does not recommend the use of sealing alone to reduce radon because, by itself, sealing has not been shown to lower radon levels significantly or consistently. Sealing does two things, it limits the flow of radon into your home and it reduces the loss of conditioned air, thereby making other radon reduction techniques more effective and cost-efficient. Sealing cracks and other openings in the floors and walls is a basic part of most approaches to radon reduction. The right system depends on the design of your home and other factors. Radon contractors use other methods that may also work in your home. Similar systems can also be installed in houses with crawl spaces. These systems remove radon gas from below the concrete floor and the foundation before it can enter the home. Such systems are called "sub-slab depressurization," and do not require major changes to your home. In many cases, simple systems using underground pipes and an exhaust fan may be used to reduce radon. the EPA generally recommends methods that prevent the entry of radon.
Some techniques prevent radon from entering your home while others reduce radon levels after it has entered. There are several methods that a contractor can use to lower radon levels in your home. In these situations a combination of radon reduction techniques may be needed to reduce radon levels to below 4 pCi/L. For instance, it is common to have a basement under part of the house and to have a slab-on-grade or crawlspace under the rest of the house. Some houses have more than one foundation design feature. For example: basement, slab-on-grade (concrete poured at ground level), or crawlspace (a shallow unfinished space under the first floor). Houses are generally categorized according to their foundation design. Your house type will affect the kind of radon reduction system that will work best. What can be done to reduce radon in a home? In addition, the current occupants-not just the buyer's occupants-will reap the benefit of reduced risk. This often provides more time to address the problem and find the most cost-effective solution. Homeowners should consider correcting a radon problem before making final preparations to sell a home. Another potential benefit of these systems is reduced infiltration of moist soil air with the radon, which may reduce the humidity level in the basement of the home. Standard radon reduction systems are usually effective within 24 hours and maintain low levels as long as the fan is operating.
The primary benefit is reducing the risk of developing lung cancer. What are the benefits of radon mitigation? The EPA recommends that you take action to reduce your home's indoor radon levels if your radon test result is 4 pCi/L or higher.
