THE SHORT ANSWER
How to Estimate a Radon Mitigation System
An active sub-slab system on one floor with one fan and 12 labor hours at $65 totals about $2,280.
Choose the system type
Active sub-slab pulls radon from under the slab with a fan; crawlspace systems ventilate a crawl space; passive systems rely on stack effect.
- System type
- Floors served
- Number of fans
- Labor
Fans drive the cost
Each mitigation fan adds a significant line. Most homes need one fan; larger or split slabs may need two.
Floors change the routing
A multi-story home needs longer pipe routing and more labor to pull the radon up and out. Add a per-floor charge.
Test after install
A mitigation system is verified by a post-install radon test. Confirm who runs the test and include the cost.
