Why does my fireplace smell like rotten eggs even when it's off?
In Hendersonville, most homes off the Main Street and Spartanburg Highway mains run on natural gas, so a rotten-egg smell from a fireplace that's off points to a leak — the odorant added to gas is warning you. Don't flip a switch or light anything. Move everyone outside, then call your gas utility and us at (828) 545-0525.
The mercaptan warning on the gas main
Utilities add mercaptan to odorless natural gas precisely so a leak hits your nose as rotten eggs, sulfur, or a struck match. On a switched-off fireplace, that smell usually traces to a loose fitting, a valve that didn't fully seat, or a pilot that dropped out while gas kept feeding the line. Hendersonville's popularity with retirees is one reason so many homes here run quiet, low-maintenance sealed gas units — but sealed doesn't mean the supply line and connections can't work loose.
Clay soil, settling homes, stressed connections
The clay-heavy soil around Henderson County settles over the years and stresses older masonry chimneys — and the same ground movement can strain a rigid gas connection where the line enters the firebox. If you smell gas with the unit off, don't investigate first: leave the thermostat, switches, and garage door untouched, get the household and pets outside, and from a safe distance call your gas provider or 911, then us.
Licensed work, Henderson County permit
Repairing or pressure-testing a gas line is licensed work in North Carolina, and a leak is the last place for guesswork. Steady Flame is a licensed gas contractor — we pull the Henderson County permit, find the leak, pressure-test the line, and back the repair. A faint one-second whiff at startup can be normal; a persistent rotten-egg odor with the fireplace off always gets a technician out. Call (828) 545-0525.
