Can a fireplace make radon levels in my house worse?
It can, and Candler's fast-growing subdivisions are worth a second look. This is propane country, and many new homes here came with basic decorative fireboxes that depressurize the house and pull soil gas up from the slab. The Hominy Valley bowl, which traps air and favors clean-burning appliances, is the same terrain where radon can accumulate. Buncombe County reads high, so test the lowest lived-in level.
New subdivisions, basic fireboxes
Candler's growth brought a lot of homes with builder-grade decorative fireboxes — open units that make flame but not much heat, and that still pull household air up the flue every time they run. Owners here often want to upgrade to something that actually heats within a few years, and the radon question is a good reason to do it sooner. A depressurizing open box in a new home draws its make-up air straight up from the ground, so test the lowest floor before you decide.
The valley bowl and propane both point to sealed
Hominy Valley's natural bowl holds air, which is exactly why sealed, clean-burning appliances make sense here and why radon deserves attention. On [propane](/guides/natural-gas-vs-propane-in-wnc), a sealed direct-vent unit draws combustion air from outside and vents out, so it doesn't add to indoor air problems or fight the house for air. An open wood firebox is the heavy puller; a sealed gas insert or a wood-to-gas conversion stops that pull.
Test, then the fireplace side is ours
We don't install radon mitigation — the sub-slab system is a separate specialty. The fireplace's part is ours, permitted with Buncombe County and pressure-tested as licensed propane and gas work; a licensed gas contractor is the only one who can legally connect that propane line. We're 15 minutes west of the Asheville showroom. Test with an inexpensive kit first, then coordinate the mitigation and the hearth as one project. Call (828) 545-0525.
