WE ARE THE ONLY RADON MITIGATION COMPANY IN THE UNITED STATES TO UNIVERSALLY ADOPT THE WORLD HEALTH ORGANIZATION’S STRICTER MITIGATION THRESHOLD OF 2.7 PCI/L OR LOWER. WE BELIEVE THAT THE EPA SHOULD ADOPT THIS THRESHOLD AS WELL AND WILL NOT WAIT FOR IT TO HOLD US TO THIS HIGHER STANDARD. WE UNDERSTAND THAT OUR CUSTOMER’S LIVES ARE AT STAKE AND TAKE OUR WORK VERY SERIOUSLY.
Radon Mitigation Services Throughout New York Connecticut, and Consulting/System Servicing in Southern California
Radon Mitigation of America, Inc. (RMCA) has been serving New York and Connecticut for nearly 30 years. We are experts in designing the best way to mitigate your dwellings of radon. We follow the EPA standards and use top of the line products.
It is a good practice to correct a radon problem before you put your house on the market. High radon levels have been known to affect home sales. Radon mitigation systems do not require major changes to your home and do not adversely effect the value of your home! Homes mitigated to acceptable levels have added protection against radon and other soil gases that make it uncomfortable to spend time in one’s basement. Radon systems help resolve all of these gas intrusions as they do not target radon alone and therefore make the mitigation system an excellent selling point. Contact us for more information!
Determining Appropriate Radon Reduction Method
The kind of radon reduction system that will work best depends on your home’s foundation type, tightness, and foundational materials. Radon reduction systems can be grouped by house foundation design.
In houses that have a basement, crawlspace or a slab-on-grade foundation, radon is usually reduced by one, or a combination of four types of “Active Soil Depressurization.” The subsets include:
Sub-slab Depressurization: The most common permutation of radon mitigation focuses on applying constant vacuum pressure through the slab and onto substrate embedded under the slab and between the foundational footings.
Drain Tile Depressurization: This form of mitigation focuses suction on an interior, or exterior footing drain network, when present. It is often the most efficient form of radon mitigation because the pre-existing drainage system provides an airflow pathway for the radon fan to evenly extract soil gases from wherever the drainage system is installed (often the entire perimeter of the home’s foundation).
Block Wall Depressurization: This form of depressurization is widely used by RMCA in homes with concrete block foundation walls, which most homes built between 1930 and 1990 were built with. Those blocks, while structurally stable, have hollow cavities that permit radon to flow into the home through adjacent soil resting against the home’s foundation walls. Without incorporating block wall depressurization into many homes, a radon system will often be severely limited in how much reduction it can consistently achieve. RMCA prides itself in having advanced expertise with this form of radon mitigation as it is not applicable to all foundation walls with concrete blocks but when applied appropriately has been a game changer for many of our projects. Frequently we get contacted by homeowners who had a different company install the mitigation system for one reason or another and we are able to carefully incorporate block wall suction into the system and turn it from a barely performing system into an efficient radon extraction masterpiece with resulting radon levels consistently below 1.5 pCi/L.
Sub-Membrane Depressurization, or Crawl Space Depressurization: This form of mitigation addresses crawl spaces with exposed dirt floors. Without a concrete slab or vapor barrier tightly affixed over crawl space soil, the soil gas has an unimpeded path either up through the floor boards to the living space above, or through any openings or hatches into adjacent basement living spaces. To resolve this issue, RMCA installs perforated suction piping directly on top of the soil and blankets the suction piping with a membrane (6 to 10 mil polyethylene sheeting) and carefully affixes the sheeting to the foundation walls which confines the system suction to the soil area under the sheet. This is the most labor-intensive form of mitigation often requiring difficult work conditions in confined, hazardous areas in addition to significant material costs for the suction piping, membrane material, and fasteners/adhesives to ensure a that the vapor barrier will remain in-place for decades to come. Average costs for this form of radon mitigation range widely depending on the size of the space and the difficulty of moving within it. Pricing may vary between $2,500 and $10,000 for these projects.
Other Types of Radon Reduction Methods
Other radon reduction techniques that can be used in any type of house include: heat recovery ventilation, or energy recovery ventilation.
A heat recovery ventilator (HRV), also called an air-to-air heat exchanger can be installed to increase ventilation which will help reduce the radon levels in your home. An HRV will increase ventilation by introducing outdoor air while using the heated or cooled air being exhausted to warm or cool the incoming air. HRVs are more effective in reducing radon levels when used to ventilate only the basement and when the radon level is less than 10 pCi/L.
Note: Sealing entry points may not lower radon levels significantly or consistently and is not recommended by the EPA as the sole method for mitigation. However sealing may enhance the performance of the mitigation system.
