Ensuring Safe Air Quality in Your Home
Radon Mitigation Solutions Tailored to Your Needs
Discover how our expert radon mitigation services can drastically reduce radon levels in your home or office, ensuring a safer living and working environment.
Effective Radon Reduction Strategies
Comprehensive Radon Mitigation Techniques
Reducing radon levels in your home or office involves selecting the right mitigation strategy based on the building’s unique characteristics. Our experienced team evaluates your property to determine the most effective solution.
Sub-Slab Depressurization: This is the most common method, ideal for buildings with concrete slabs. It involves creating a vacuum under the slab to draw out radon gas before it can enter the building.
Sub-Membrane Depressurization: Suitable for crawl spaces or older homes without concrete slabs, this method uses a sealed membrane to cover exposed earth, with a vacuum system to remove radon gas.
The Wall of Shame
Spotting Poor Radon Installations
Welcome to ‘The Wall of Shame,’ where we showcase photos of poorly executed radon mitigation installations. These images highlight the mistakes made by so-called professionals, DIY homeowners, and even builders. Our goal is to educate and inform, ensuring you understand the importance of proper installation to effectively reduce radon levels in your home or office.
Sub-Slab Depressurization
Effectiveness and Success Stories
Sub-slab depressurization systems are highly effective in reducing radon levels, even in homes with extremely high concentrations. For instance, we encountered a home with a radon level of 331 pCi/L. After installing a sub-slab depressurization system, the radon levels dropped to less than 0.4 pCi/L. This dramatic reduction showcases the system’s capability to bring radon levels well below the recommended safety limits.
Choosing the Right Mitigation Company
The type of aggregate under your home is the key variable affecting how low radon concentrations can be reduced. Proper air movement under the home is crucial for effective radon mitigation.
This is where the expertise and experience of the mitigation company come into play. Choosing a knowledgeable and experienced company ensures that the system is installed correctly and operates efficiently.
At Radon Done Right, we pride ourselves on our thorough understanding of radon mitigation techniques, ensuring your home is safe and radon-free.
Sub-Slab Depressurization Systems
Sub-slab depressurization systems are the most common and effective method for reducing radon levels in homes with concrete slabs. The system involves creating a vacuum under the slab to draw out radon gas before it can enter the living space. This is achieved by sealing a PVC pipe to a hole cut into the slab, which is then connected to an inline fan.
The PVC pipe must terminate at least 12 inches above the roof eaves and be positioned at least 10 feet away or 2 feet above any windows or openings. The inline fan creates a vacuum that pulls radon gas from beneath the slab, directing it safely outside. This method can significantly reduce radon levels, often bringing them down to below 2 pCi/L.
Proper installation is crucial for the system’s effectiveness. The type of aggregate under the home plays a significant role in how well the system can move air. Experienced contractors will ensure the PVC pipe is correctly sealed and the fan is appropriately installed, either in the attic or garage attic space. This ensures that the radon gas is effectively vented out, improving indoor air quality.
Choosing a registered radon contractor with experience in sub-slab depressurization is essential for achieving the best results. They will ensure that all components are correctly installed and meet the necessary termination requirements, providing peace of mind and a safer home environment.
Sub-Membrane Depressurization Systems
Effective Solutions for Crawl Spaces
Sub-membrane depressurization systems are ideal for homes with crawl spaces or older homes without concrete slabs. This method involves laying a poly membrane over the exposed earth or stone in the crawl space. The membrane is then sealed to the exterior walls using various techniques to ensure an airtight barrier.
A vacuum is drawn from under the poly membrane, similar to the sub-slab depressurization system. An inline fan is used to pull radon gas from beneath the membrane, directing it outside before it can enter the living space. This method is highly effective in reducing radon levels in homes without concrete slabs.
Heat Recovery Ventilators (HRVs)
Heat Recovery Ventilators (HRVs) are an alternative solution for radon mitigation, particularly in situations where sub-slab or sub-membrane depressurization systems are not feasible. HRVs work by increasing the air exchange rate in the basement, effectively diluting the radon concentration. The system brings in outside air and reconditions it before releasing it into the basement.
During the summer, the HRV cools the incoming warm air with the cooler air leaving the basement. In the winter, it warms the incoming cold air with the warmer air exiting the basement. This process helps to maintain a balanced indoor climate while reducing radon levels. However, HRVs typically achieve a reduction rate of 50% to 75%, making them less effective than other methods.
