Can a fireplace make radon levels in my house worse?
It can, and Fletcher's mix of builder-grade and brand-new construction is worth a look. This is natural-gas-main country, and the 1990s subdivisions here came with basic open decorative fireboxes that depressurize a home, while the tight new I-26 corridor builds concentrate whatever pull a fireplace creates. Henderson County reads high for radon, so test the lowest lived-in level regardless of the home's age.
Builder-grade decorative boxes still pull
A lot of Fletcher's 1990s subdivision fireplaces are open, decorative units that were never meant to heat, but they still send room air up the flue and still make the house draw make-up air up from the slab. Newer I-26 corridor homes and commercial spaces are built tight, so a depressurizing fireplace has fewer wall gaps to pull from and leans harder on the ground. Slab-on-grade construction, common in these builds, puts living space in direct contact with radon-bearing soil.
Sealed gas suits the commercial demand too
Fletcher's airport-area commercial buildings want gas fireplaces and outdoor features, and for indoor units a sealed [direct-vent install](/services/gas-fireplace-installation) is the right call — combustion sealed off from the occupied space, air drawn from outside, minimal effect on building pressure. An open firebox in a tight commercial shell is the kind of thing that pulls soil gas up through a slab-on-grade floor. Outdoor gas features, open to the air, add nothing to the radon load.
Test, then the fireplace half is ours
Radon mitigation — the sub-slab suction system — is a separate specialty, not our trade. We handle the fireplace, permitted with Henderson County and pressure-tested as licensed gas work. We're 20 minutes south of the Asheville showroom, close enough for a quick assessment. Test first with a cheap kit, then coordinate the mitigation and the hearth. Call (828) 545-0525.
