Can a fireplace make radon levels in my house worse?
It can, and in Fairview wood is the reason to pay attention. This is propane country, but the wooded lots make wood heat the natural choice, and an open wood fire pulls more house air — and more radon up from the foundation — than any other hearth. Rural homes on crawl spaces give that soil gas an easy route. Test the lowest lived-in floor; this is high-radon country.
Wood country means the heavy pull
Fairview's wooded lots make firewood cheap and wood heat popular, and that's fine — but an open wood fireplace is the strongest depressurizer a home can run, sending hundreds of cubic feet of indoor air up the flue and drawing make-up air up through the crawl and slab. The same annual fall chimney sweep that keeps creosote from causing a chimney fire is a good moment to think about how hard that firebox pulls on the house. If you burn wood, test the home.
Propane sealed gas is the low-pull alternative
If you're open to changing, a sealed [direct-vent propane fireplace](/guides/natural-gas-vs-propane-in-wnc) heats without recruiting soil gas — combustion air comes from outside, exhaust goes out, and house pressure barely moves. A wood-to-gas conversion with a sealed insert keeps the flame and the look while ending the radon pull. Plenty of Fairview homeowners keep wood for its outage-proof heat, which is a fair call — just know your radon number if you do.
Test, then the fireplace half is ours
Radon mitigation — the sub-slab system — is a separate trade we don't install. The fireplace's contribution is ours, from combustion-air kits to insert conversions, permitted with Buncombe County and pressure-tested as licensed propane and gas work a handyman can't legally connect. We're 15 minutes east of the Asheville showroom. Test first, then handle the mitigation and the hearth together so neither undoes the other. Call (828) 545-0525.
