Important Things That Can Affect the Cost of Radon Systems

  • The construction style of the home.  Many Colorado homes have finished basements that limit routing options. Some homes have footings that will restrict the flow of the radon systems. Multiple levels or multiple footprint types can change the system design.
  • Crawlspaces must be sealed. If the home has a crawlspace, it must be sealed to reduce radon properly. Learn more about how crawlspaces should be sealed on the Crawl Space Vapor Barrier page.  
  • Exterior routing vs. Internally hidden system. Exterior radon mitigation systems are generally less expensive than internal options. Internally installed radon systems exhaust through the roof. Garage attic radon systems and post-construction are generally less costly than systems routed through walls, closets or framing.
  • Take all foundation & construction details into consideration.  Radon enters the house through the foundation, and every house has unique foundation details. Some houses even have more than one foundation (a basement plus a crawl space or slab, for example). The size and type(s) of foundation will factor in system cost. So will details like sump pumps, drainage, and waterproofing features, and the location of fixed equipment like the furnaces and water heater. If part of the basement is finished and used as living space, this will also affect the cost by placing constraints on where plastic tubing can be installed.
