Radon Mitigation Systems

Cost for Radon Mitigation System (Existing Homes)

These prices are for typical installations. Prices may change upon inspection. Final price will be determined on sub-slab type material, drain tile configuration, local electrical / permit costs, treating crawl spaces, and travel time. A written proposal will be provided at time of inspection.

Cost for Radon Mitigation System (New Construction)

These prices are based on typical stick construction homes. New construction is less expensive as it's considerably easier to install a Radon mitigation system during construction. Fewer materials are also needed on a new construction installation. The excavator/plumber is responsible for installing a sealed sump pump pit. An electrician is required to install a light fixture with a grounded outlet near the vent pipe penetration during rough-in. We would need to be at the home during the plumbing rough-in stage of construction.

Active Moisture Control System $550-$750
Passive System: Fox Valley / Oshkosh / Green Bay / Fond du Lac areas, and beyond (Passive system has no fan, carries no guarantee, but is set up so that it can be made active at a later date, if desired.) $350-$550
