How Much Does Radon Mitigation Cost?

Quick access menu

    Radon mitigation cost ranges from $100-$3000. Cost varies depending on what mitigation method is used, location and the contractor that does the job. Cost also varies depending on whether homeowners do the job themselves or whether they hire a contractor to do the job for them. When a contractor does the job, they will usually test for radon, seal any cracks and holes in the foundation to help stop the radon from getting in, and use a suction system to remove the radon gas in the house. When done by a professional, radon mitigation cost ranges from $600- $2500, plus an additional $100-$600 if the contractor has to seal up holes and cracks in the house’s foundation. In addition, homeowners that use well water should have their well water tested regularly for radon contamination. If well water has unsafe radon levels, homeowners will need to install a radon mitigation system; water radon mitigation systems range in price from $1000-$5000.

    Radon Testing Cost

    Homes and wells should be tested every couple of years for radon. To have a home tested for radon, homeowners can either hire a professional to test it or purchase a DIY home radon test. DIY radon tests can be purchased in most hardware stores, home repair stores, department stores and online. DIY radon tests cost from $15-$40. The cost of a radon test done by a professional contractor is around $100. American citizens can visit the USA Environmental Protection Agency’ website to get coupons for radon test kits.

    How Much Does Radon Remediation Cost?

    Radon mitigation services range from $100-$3000. Radon mitigation services vary per contractor and location. Radon removal cost is more expensive in areas with a high cost of living compared to areas with a low cost of living. Radon remediation cost is also affected by what radon mitigation system is installed in the house. Radon remediation cost to seal openings ranges from $100-$600. Radon mitigation services to install a sub slab depressurization system cost from $800- $2500.  Radon removal cost with an air exchanger ranges from $200-$500.

    How Much Does A Radon Mitigation System Cost?

    There are several different radon mitigation systems for homeowners to choose from. Radon mitigation systems range in price from $100-$3000. Cost varies depending on the type of system that is chosen and if homeowners install it themselves or hire a contractor to install it for them. The most common radon mitigation systems are sub slab depressurization, air exchangers and opening sealing. Radon mitigation systems are most expensive when sub slab depressurization is used. Radon mitigation system cost for sub slab depressurization ranges from $800-$2500, for air exchangers pricing ranges from $200-$500, and for sealing openings pricing ranges from $100-$600.

    Radon Mitigation Techniques

    There are several different radon mitigation techniques for home owners to choose from: sub slab depressurization, sub slab depressurization with a crawl space, opening sealing and air exchange. A sub slab depressurization is when a fan and PVC pipe is used to draw  the air from below the basement floor and vent it above the house. A sub slab depressurization with a crawl space is much the same as a sub slab depressurization, but it also includes drawing the air from the crawl space below the house. Radon removal cost using the sub slab depressurization techniques ranges from $800-$2500.

    Air exchangers are usually only used when a sub slab depressurization is not viable. Air exchangers usually use two fans to help remove harmful radon from the house and bring in fresh safe air. Air exchangers do not work as well as sub slab depressurization and often add 15%-20% on to the homeowners heating and cooling bill. Radon removal cost is usually less with air exchangers than with sub slab depressurization.  Radon mitigation cost using the air exchanger techniques ranges from $200-$500.

    Another radon mitigation technique is sealing openings. By sealing all the cracks and holes in the house and making it air tight, some radon is kept out; however, this technique does not always work well, and at the most will drop the radon levels in the house by 50%. Radon removal cost using the sealing openings technique ranges from $100-$600.

    Acceptable Radon Levels

    The Environmental Protection Agency in the United States strongly recommends that any home that gets a 4 pCi/L or higher on a radon test be mitigated immediately. They also recommend that any home that gets a 2 pCi/L – 4 pCi/L on a radon test be mitigated sometime in the near future. Radon levels below 2 pCi/L are considered safe; however, homeowners are safest to try to keep radon levels below 1 pCi/L if possible.

    Where Does Radon Come From?

    Radon is an invisible odor-free gas that is caused by the natural decay of uranium and radon that is in the soil beneath a house. The radon slowly gets into the house and over time can build up to very dangerous levels. Radon can take many years to reach dangerous levels in the house so many people figure they do not need to worry about it; however, as radon is so dangerous to a person’s health it is important that homes gets tested regularly for it. Radon is the second leading cause of lung cancer in the United States and is responsible for about 25,000 deaths each year. An estimated one in fifteen homes in the United States have dangerous levels of radon in their home.

    Do It Yourself Radon Mitigation

    Installing a radon mitigation system is not extremely difficult; however if installed incorrectly it can increase the radon levels in the house instead of decreasing them. In addition, if the radon mitigation system is installed incorrectly, it can cause a buildup of carbon monoxide. Do it yourself radon mitigation costs range from $200-$500. DIY radon mitigation systems can be purchased in most home improvement and hardware stores.
