In general, the cost to install a mitigation system is quite small when compared to the value of the house. The cost to install a mitigation system is roughly in line with home improvements such as replacing a roof or installing a central air conditioning unit. The cost for the installation of a radon mitigation system typically ranges between $2,500-4,000.
The cost depends on how radon gas enters the home and moves within it, and each home is unique. Costs for mitigation of adjacent homes can vary significantly.
The following costs can vary greatly depending on the source of the radon, and the complexity and usage of the house in question.

| Type of System | Considerations | Approximate Cost* |
| SSD | Pricing will vary depending on the amount of work to be performed, such as: • Preferred route of radon exhaust pipe; • Number of suction points and/or radon fans required, which can be affected by sub-slab soil conditions or the configuration of the home structure beneath the slab (e.g., presence of grade beams to inhibit air flow). | $2,500-$4,500 |
| SMD | Pricing will vary depending on the amount of soil to be covered and the degree of difficulty to access the crawlspace. | $2,500-$5,000 |
| HRV | Pricing will vary depending on the size of HRV required and the complexity of duct distribution. A typical radon HRV would exchange air in the basement independent of upper floors. | $2,500-$4,500 |
* Approximate cost estimates assume a home with code compliant construction and are based on reasonable (i.e., local) travel distances for mitigation professionals.
