Radon mitigation is an effective process for reducing radon gas concentrations in buildings. Radon Mitigation system installation methods do vary depending on the building and foundation type. For example, homes with crawl spaces require encapsulation, creating an airtight seal compared to houses with basements that require suction points installed through the concrete slab. In summary, regardless of the foundation type, the goal remains the same. We will draw out the Radon Gas from beneath the structure and re-direct it outside of the building and above the roofline using PVC piping and an appropriately sized radon mitigation fan.

Estimates are followed by a formal proposal outlining the plan of action fitting for your home. Upon verbal acceptance and scheduling, a service agreement/contract will be sent for signature.
Post mitigation testing will occur upon the completion of the installation and will remain for at least 72 hours or be set for 48 hours 24 hours after completion.
The AMG mitigation fans we use come with a 5-year manufacturer's warranty. Fan replacements after (5) years will be sourced and installed at cost. Elliott Home Services also offers a limited lifetime warranty on all other portions of the mitigation system. Elliott Home Services will repair any malfunction to the radon mitigation system that is not caused by the occupants of the home at no additional cost.
Crawlspaces are encapsulated using a 12 mil polyethylene cross-woven vapor barrier tough enough to withstand damage from reentering the crawl space when needed. The vapor barrier will be sealed to the crawlspace walls using high-quality butyl tape and then mechanically fastened using poly term bar, masonry screws, wood screws, and push pins. All other exposed areas and penetrations are sealed using spray foam. Perforated pipe is installed below the vapor barrier along the crawlspace's entire perimeter to complete a proper field extension for airflow purposes. 3" schedule 40 PVC piping is connected to the perforated piping then exits the home in the desired location where the radon mitigation fan will be installed. The system will extend upwards and exhaust to 1' above the roofline. In some cases, the piping can exit to an attached garage and exit through the home's roof to keep the mitigation system internal. By separating the soil and outside temperatures from the floor joists, crawlspace, and other building components, we have created a more climate-controlled environment. As a result, we have reduced the possibility of any future mold, mildew, or moisture concerns caused by outside elements.
The installation summary involves a 5" concrete core drill through the basement/slab, ideally in a laundry/utility room. 5-15 gallons of sub-slab material will be removed to create an appropriately sized suction pit required to remove the radon gas. The amount extracted is determined by the material found. 3" schedule 40 PVC piping is installed below the slab and either directed upward through the ceiling and into the attic space or through the band board or wall. An appropriately sized AMG radon mitigation fan is installed with an attached electrical line cord. The sqft of the home and sub-slab material found determines the fan's size. The exhaust will extend to 1' above the roofline. All necessary areas in the basement/slab will be sealed to an airtight condition determined by visual inspection and diagnostic testing. Additional diagnostic testing will be performed during installation to determine if a single suction point will effectively mitigate the structure. Additional suction points may be required.
Single suction point | Gravel sub-slab material
Single suction point | Clay sub-slab material
This will be more labor-intensive & require multiple suction points
Necessary for mitigating radon for homes with this foundation type.
Crawlspace encapsulations are priced per square foot. Pricing varies depending on crawl space condition, size, height, and accessibility. Please call to schedule a free estimate for accurate pricing (812) 606-7549.
Gravel, clay, and sand are various sub-slab materials commonly found under foundations, and all restrict air movement differently. Sub-slab materials must be considered as they do alter the price of mitigation installations. Homes built in the 1970's era or before tend to have clay sub-slab materials; therefore, the need for additional suction points is greater. With clay soils, diagnostic testing will be performed along the way to determine the need for additional suction points. Still, our goal will always be to mitigate while being as minimally invasive as possible.
