Radon mitigation systems are becoming an important part of every home. Since radon can contaminate the indoor air it can come from various sources. There are different parts of the house where radon remediation can be done. However it is largely dependent on the type of foundation your home has. There are generally three types of foundation. First there is the one with a basement. The second is a slab on grade. Finally there is the crawl space. For this particular radon mitigation, we focus on houses with crawl spaces.
Remember that the radon usually comes from the ground. However a house with a crawl space means that there is a space between the ground and the house.
One good way to implement a radon abatement system and thus reduce the amount of radon is the use of a plastic sheet. Note that the plastic must be one of high density in order for the radon mitigation to actually work. The seams of the sheet are then sealed with its edges sealed to the walls of the floor foundation. Since this does not remove the radon will remain if this is all that is done, it is important to place a perforated pipe under the plastic. The pipe is then connected to an exhaust pipe ensuring that the radon gas is siphoned and released to the atmosphere.
This type of suctioning method is known as submembrance suction. If done correctly it can indeed lower the amount of radon going inside the house. Note that this method means that the pipe is under the soil. Another method is to just put the pipe in the space and then draw the air out directly in the crawl space. It acts like a depressurization though it is not as effective as the submembrance suction method. If you also use the second method, you will need to ensure that the crawlspace and other parts of the house are sealed from each other. If the radon gas leaks inside the house while you are suctioning it then contamination is just one problem as you may need to deal with the possibility of combustion.
While you may have the necessary resources or materials to do this one your own, it is always best to consult first with a professional contractor. MTN Inc., which is located in Littleton, Colorado, is one that you can talk to since they offer free consultation.
They may do the mitigation differently from what is explained here but at least this gives you an idea of what the work entails. This will allow you to bargain with them if necessary or determine if the price being quoted is the correct one.

Remember the method from a crawl space mitigation is likely different from a house with a basement. Still regardless of the method, what is important is the result. In the end the reason you do radon mitigation is to lessen any risk associated with radon contamination.
