Every Radon Mitigation System is Custom Designed
Radon mitigation system cost varies dramatically depending on how the home is constructed. Radon system costs can range from $750 to $5,000 per home. The average cost range to install a radon mitigation system in an average single-family home is between $1,100 and $2,500, with $1,400 being the average.
Factors That Impact the Price of a Radon Mitigation System
The price of a radon system depends on many factors. Some factors only change the price a little, while other factors have a bigger effect. Here is a list of some of the factors that go into the cost of radon mitigation.
FACTOR | WHAT MAY MAKE THE COST MORE EXPENSIVE |
Size of the home | Homes larger than 4,000 sq. ft. |
Age of the home | Older homes can be more difficult to fix |
Foundation | Cinder block or stone foundations |
Siding | Specialty siding (Dryvit, flagstone, asbestos, etc.) |
Roofing material | Specialty roofing (cedar shake, slate, etc.) |
Height of building | Tall buildings may require specialty ladders or lifts |
Home Owner’s Association (HOA) requirements | Some HOA’s are difficult to work with or have strict standards |
Village requirements | Some Village require permits and/or licensed electricians |
Skeletal system already installed | This will actually LOWER your price (if it was installed properly) |
Basement size | A basement larger than 2,000 sq. ft. may require additional suction point(s) and/or caulking |
Finished basement characteristics | May not allow for a good system location, may require more than one system |
Excessive floor cracks in the basement | Will require additional sealing |
Floor drain(s) not trapped | This is a radon source that will need to be addressed |
Radiant heat under the basement floor or slab-on-grade area | Must know the location so we don’t hit while drilling, may require Thermal Imaging Camera to locate |
Groundwater sump pump | Must be working or may need to be serviced |
Battery backup sump pump | Must be working or may need to be serviced, should be a submersible style to achieve an airtight seal |
Interior drain tile system | May be a major radon entry route and may require special sealing |
Crawl space | An additional radon entry route at a different level than the basement |
Crawl space composition | A gravel or dirt crawl space requires special sealing |
Crawl space size | The size of a gravel or dirt crawl space is a factor in the pricing |
Height of the crawl space | If the gravel crawl space is less than 3′ tall, it is more difficult to work in |
Crawl space access | A crawl space must be accessible and have an opening a minimum of 2′ x 2′ |
Items stored/installed in crawl space | A crawl space must be empty of debris, installed items such as a furnace, posts, or shelving make it more difficult to seal |
Insulation on walls of crawl space | The bottom of the insulation will have to be removed, the insulation could contain asbestos if the home was built prior to 1973 |
Slab-on-grade areas of the home | An additional radon entry route at a different level than the basemen |
Ductwork or utilities in the slab | Ductwork could affect the success of the system and may need to be sealed. Buried utilities may require concrete scanning using Ground Penetrating Radar |
Additions to the home | An additional radon entry route at different levels than the original home, a footing may separate the two areas, may require additional suction point(s) |
High water table | Makes it more difficult to draw air from underneath the home, may require additional suction point(s) or modifications to the sump pit/pump |
Poor soil conditions (clay, sand, dirt, compacted gravel, etc.) | Makes it more difficult to draw air from underneath the home, may require additional suction point(s), and/or a higher suction fan |
Asbestos | Asbestos siding, insulation, or vermiculite may need to be professionally removed prior to a radon system being installed |
Historically significant home | May need to follow special Village standards |
Power lines in the way | May need Com Ed to cut power to the home in order to install the exterior exhaust pipe |
