How mitigation works in Spring Grove homes
Most York County systems are sub-slab depressurization: a suction point under the slab, PVC pipe, and an inline fan that vents soil gas above the roofline. With Spring Grove's high readings, larger or multi-section foundations sometimes need more than one suction point to pull evenly from under the whole slab.
Across York County systems reported to DEP, the median radon level fell from 12 pCi/L before mitigation to 1.0 pCi/L after, and 97.4% of systems tested below 4.0 afterward. See how the systems work.
Hiring a certified mitigator for your Spring Grove home
Pennsylvania requires DEP certification for anyone performing radon testing or mitigation for hire. Start in the PA DEP Radon Services Directory and confirm the name you're considering is certified for mitigation, not just testing.
Ask for a written scope, a fan warranty, and a post-mitigation test to confirm the level dropped. Our hiring guide has the full checklist.
