What this calculator estimates
Estimate a radon-mitigation project cost from base system pricing, foundation zones, crawl-space work, electrical service, testing and permits.
How to use it
Enter Base active mitigation system ($); Foundation suction zones; Cost per zone beyond the first ($); Crawl-space membrane work ($); Electrical outlet and fan wiring ($); Post-installation testing and monitor ($); Permits and inspection ($). Select Calculate to update the results.
How the calculation works
The calculator starts with a base active system, adds extra suction zones and crawl-space work, then includes electrical, testing and permit costs.
Worked example: starting scenario
| Base active mitigation system ($) | 1500 |
|---|---|
| Foundation suction zones | 2 |
| Cost per zone beyond the first ($) | 500 |
| Crawl-space membrane work ($) | 0 |
| Electrical outlet and fan wiring ($) | 350 |
| Post-installation testing and monitor ($) | 250 |
| Permits and inspection ($) | 150 |
| Estimated radon-mitigation cost | $2,750.00 |
|---|---|
| Base system and added zones | $2,000.00 |
| Crawl-space work | $0.00 |
| Electrical, testing and permits | $750.00 |
| Average cost per suction zone | $1,375.00 |
Important limitations
Foundation type, number of zones, crawl spaces, routing, electrical access, local code, radon level and contractor warranty affect actual pricing.
