Westerville and Franklin County

Westerville routes through our Franklin County territory, with eastern sections also served through our Delaware territory. EPA places both counties in Zone 1 on its Map of Radon Zones. Ohio licenses radon mitigation contractors through the Department of Health — the county line has no effect on who may work.

If the result surfaced in a transaction

Family moves and relocations drive a steady market. Ohio’s Residential Property Disclosure Form asks sellers about known radon testing and results; nothing requires testing or mitigation. In newer northern subdivisions, checking for a passive rough-in is the useful first diligence step.

The housing you’re mitigating

Uptown-area housing brings older block and brick foundations with full basements and additions. Northern subdivision construction is modern poured work with deep basements, sump systems, and attached garages. Split-levels in the middle vintages deserve zone-by-zone quotes.

Westerville questions, answered straight

How does mitigation work on a split-level?

By treating the house as its zones — basement slab, any slab-on-grade section, and any crawl area, commonly all on one fan. The failure mode is a quote that silently skips a zone.

How do I find a passive rough-in?

Look in the attic for a capped 3–4 inch PVC run exiting the roof, often labeled, originating below the basement slab. If it exists and your test is elevated, a licensed contractor can add an in-line fan and indicator.

Does the county line change our quotes?

No. Ohio licensing is statewide, and we route Westerville through one territory. Quote differences come from your foundation and routing, never from which county the house sits in.
