HOW TO USE IT
How to use the Radon Mitigation System Cost Calculator
- 1
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.
- 2
Fans drive the cost: Each mitigation fan adds a significant line. Most homes need one fan; larger or split slabs may need two.
- 3
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.
- 4
Test after install: A mitigation system is verified by a post-install radon test. Confirm who runs the test and include the cost.
THE MATH
Radon mitigation calculation method
An active sub-slab system on one floor with one fan and 12 labor hours at $65 totals about $2,280.Each mitigation fan adds a significant line. Most homes need one fan; larger or split slabs may need two.

FAQ
Frequently asked questions
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.
What should I verify before using the result?
Active sub-slab systems are the most common and effective; crawlspace and passive systems are cheaper but less reliable.
Is this a final quote or design?
No. Use it as a planning estimate, then confirm measurements, local rates, product requirements, permits and jobsite conditions before bidding or building.
