Sub-membrane - Used in crawl spaces, a plastic sheet covers exposed dirt on the floor, extends up onto the wall and is sealed. A radon pipe penetrates the plastic sheeting, pulls the soil gas from the crawl space, and vents it outside. Radon mitigation system components Radon fan is located in an unconditioned space, like an attic or outside, to prevent radon leaking back into the home.
A printable version of the diagram can be found at Radon Mitigation System Diagram PDF Cost of a radon mitigation system The cost can depend on many factors including the type of radon system to be installed and how your home was built.
Finding a professional to install a radon mitigation system Minnesota requires radon mitigation professionals to be licensed. Contact licensed radon mitigation professionals to request bids. Professional does a walk-through of the home to identify the mitigation system to install.
Review key questions with professional, and request a proposal. Review bids and select a professional. Professional may perform diagnostic testing to ensure the proper fan size and correct installation.
Professional seals cracks and openings in the basement. Professional installs the radon mitigation system. Professional provides a full explanation of how the system operates to the homeowner. Retest the home to ensure the system has reduced radon levels.
Other key features of a system Radon reduction systems must be clearly labeled. They can carefully measure your existing system and install a correctly sized inline radon fan. These fans are designed to run continuously on low power and without producing much noise. That means you will likely not even notice the difference while still lowering your radon levels to a safe point. Radon testing and mitigation in apartments and condos can save many families from dangerous health risks.
The Advancing Healthy Housing Strategy effectively requires that multifamily housing gets radon testing and radon mitigation in order to receive HUD financing or re-financing. One important note is that both radon testing and if necessary radon mitigation must be supervised by a certified radon professional. National Radon Defense can help if you need to have a radon mitigation system installed for your home or multifamily housing. As a leading international network of radon professionals, our membership consists of certified radon professionals around the country.

Zip Code. Thursday, March 21st by Shannon Brelsford. What is radon mitigation? If you have radon in your home then radon mitigation can easily make your home safe again. If it has an earth floor, the preferred mitigation technique is sub-membrane suction.
With sub-membrane depressurization, the floor is covered with a thick plastic sheet sealed to the crawlspace walls, foundation piers and any penetrations of the membrane. A radon system fan and piping system then draws the radon from under the membrane and vents it outdoors. Homes with water control systems such as sump pumps, French drains, or an exterior loop of buried water-collection pipe can be effectively mitigated by connecting the active soil depressurization system to the existing water control system.
As part of installing a mitigation system, cracks and other openings in walls and floors in contact with the ground are sealed. 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. 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.
However, it is difficult to identify and permanently seal the places where radon is entering. Normal settling of your house opens new entry routes and reopens old ones. Radon fans must be located in an unoccupied attic, a garage, or outside. The fan discharge is then routed up through the roof, or up along an outside wall, to a high point on the house.
Although they must operate continually, operating costs of the fans are negligible due to their low power consumption 60 watts - less than most light bulbs - per fan. Homes should be re-tested, but no sooner than 24 hours after a mitigation system has been operational. Nevada Radon Education Program. The Nevada Radon Education Program is a partnership with the Nevada Division of Public and Behavioral Health to educate Nevadans about the health risk posed by elevated levels of radon in the home.
The Extension program offers literature, educational presentations and low cost radon test kits in many county Extension and partner offices. Published by: Howe, S. Department of Agriculture.
