Why does my fireplace smell like rotten eggs even when it's off?
In Clyde, the 1960s-80s ranch homes here often have dated fireplaces with older or retrofitted gas connections, and river humidity keeps working on the metal — so a rotten-egg smell with the fireplace off means gas is leaking. Don't spark anything. Get outside, then call your gas utility or propane supplier and us at (828) 545-0525.
Dated fireboxes, humid air, tired fittings
A lot of Clyde's housing went up between the 1960s and 80s, and those dated fireplaces are prime candidates for insert upgrades — but the older or retrofitted gas fittings behind them have been through decades of use. Clyde shares the Pigeon River valley's cold-air drainage and humidity with Canton and Waynesville, and that damp rusts dampers, degrades masonry, and corrodes gas connections. Clyde runs on a mix of gas and propane, so a rotten-egg smell with the unit off is one of those connections weeping the odorized fuel.
Out first, questions later
Don't hunt for the leak. Leave switches, the thermostat, and the garage door alone, no match, no unplugging, and get everyone and the pets outside. First know your fuel: natural gas comes through a meter — call the utility; propane comes from a tank — call the supplier named on it. Make that call and 911 from a safe distance, then reach us to locate and pressure-test the line.

In North Carolina, gas-line work is licensed — Steady Flame is a licensed gas contractor, we pull the Haywood County permit and pressure-test every line. Once the leak's handled, if that dated firebox is on its last legs we'll give you an honest read on whether an insert is worth it — no pressure. But the smell comes first: a rotten-egg odor with the unit off is an emergency. Call (828) 545-0525.
