What changes the price
EPA says the cost “depends on how your home was built and the extent of the radon problem,” and that “most homes can be fixed for about the same cost as other common home repairs.”[4] In practice, quotes usually differ by foundation type (basement, crawl space, slab, or a mix), the pipe route (inside vs. outside), the number of suction points, sealing, and electrical work. Ask each licensed mitigator to itemize these.
Getting fair quotes
- IEMA recommends requesting two or three estimates from licensed mitigation professionals.[2]
- Confirm every company in the IEMA-OHS licensee lookup.
- Compare what is included, not just the total: follow-up test, warranty, fan model, and exhaust location.
