Continuous Sub-Slab Depressurization

4 pCi/L
Spokane County is recognized as a high-radon-potential area. Radon is invisible and odorless, so testing is the only reliable way to understand the level inside a specific home. The EPA recommends corrective action at or above 4 pCi/L and consideration of mitigation between 2 and 4 pCi/L.

Frequently asked questions
Spokane Radon Mitigation FAQ
Straightforward answers for homeowners, buyers, sellers, and agents.
How fast can a radon system be installed for a real estate closing?
Many standard residential systems can be installed in one working day after evaluation. Scheduling, foundation design, electrical work, and retesting requirements may affect the final timeline.
What is an acceptable radon level in Spokane County?
The EPA recommends corrective action at 4 pCi/L or higher and considering mitigation from 2 to 4 pCi/L. No county-wide designation can determine the level inside an individual property; every home should be tested.
Will a radon mitigation system lower my home value or aesthetics?
A professionally planned system can usually be routed discreetly. Addressing elevated radon may also reassure buyers that a known environmental concern has been handled.
