At MVES we’re dedicated to helping Vermont families and businesses reduce the risk of exposure to harmful radon gas. Radon is a naturally occurring radioactive gas that seeps in through the foundation of the home, school or building. Radon gas is odorless, colorless and the number one cause for lung cancer in non-smokers. The only way to know if your home or building has elevated levels of radon gas is to test for it. At MVES we install the highest quality radon mitigation systems in Vermont. Our radon mitigation systems are designed to achieve maximum radon reduction results while maintaining the highest standards of quality and aesthetics.
Many radon mitigation systems are designed as exterior installed systems. According to AARST, the exhaust of the radon system must be vented above the highest eave of the home.
Attic Radon Mitigation Systems
Vermont radon code will allow radon mitigation systems installed through the garage attic even if the roof is at a lower elevation than the highest eave of the home. The attic installation is great for those that want to hide the radon mitigation system from view.
Crawl Space Radon Mitigation
All crawlspaces must be sealed using an air-tight membrane unless they are covered with concrete. This allows the crawl space radon mitigation system to work by creating a barrier between the soil and the indoor air. Our method of sealing crawlspaces makes for a cleaner space that helps reduce dust, musty odors and humidity in the home.
Cracks in the concrete floors can be radon entry points. The cracks are sealed using elastomeric caulk. This helps improve the performance of the radon mitigation system while reducing the amount of conditioned air that is lost from the home.
Sump Pumps and Radon
A sump can be a primary radon entry point. Just as the sump can collect water from the soil, it can collect radon. Sump pits must be sealed when installing a radon mitigation system. We seal sumps with a clear cover that allows homeowners to view the water conditions inside the sump system.
Although not mandated in Vermont radon measurement and mitigation should follow standards established by AARST and NRPP. If you are seeking an estimate for a radon mitigation system Mountain View Environmental Services will visit your home or business and provide a no cost estimate.
If you are purchasing a home with a radon system and have questions feel free to give us a call.
A few things to look for:
• The radon fan should be outside the home, in a garage attic or in an attic space above the living area of the home.
• The exhaust point should be vertical above the roof and at least two feet above an opening and/or at least ten feet horizontally from any opening including windows and skylights that can be opened.
• The fan should have an electrical disconnect within 6 feet of the fan and all exterior electrical components should be in weathertight conduit and boxes.
• Make sure the entire system is labeled and properly secured to walls and joists.
- Radon is produced as uranium naturally decays in soil layers. Occurs naturally in every US state. If your radon tests at 4 pCi/L or higher, a radon mitigation system is recommended.
- Radon is a leading cause of lung cancer, comparable to tobacco smoke and asbestos. Radon is leads to 15,400-21,800 deaths annually Homes with crawl spaces are at higher risk for radon.
- Long-term exposure to low levels of radon is actually more dangerous than a brief period of high exposure. During the winter, when the house is sealed tight, radon concentrations can be up to ten times higher
