Why does my fireplace smell like rotten eggs even when it's off?
In Flat Rock, historic homes dating to the 1800s often have gas logs set into oversized original masonry fireplaces — years of added fittings and connections that can loosen. On the natural-gas main here, a rotten-egg smell with the fireplace off means a leak. Don't light anything. Get outside, then call your gas utility and us at (828) 545-0525.
Old hearths, retrofitted gas, more places to leak
Flat Rock's 1800s homes were built around big open masonry fireboxes with aging clay flue liners, and many have had gas log sets added over the decades. Every retrofit brings a supply line, a shutoff valve, and a flex connector into an old chimney — more joints that can work loose through a century-old home's seasonal shifts. A rotten-egg or sulfur smell with the unit off is the mercaptan odorant flagging that one of those connections is escaping gas.
Preserve the character, respect the danger
We love keeping these historic hearths in service — a sealed insert even fixes the cold-air draft an old open firebox pulls into the room without losing the character. But a gas smell is not the day for admiration. Don't touch switches, the thermostat, or the garage door, don't strike a match, and get the household and pets outside. Call your gas provider or 911 from a safe spot, then us; we find and pressure-test the line before anything's relit.
Licensed hands on a historic home
In North Carolina, gas-line repair and testing is licensed work, and an old house is no place to improvise. Steady Flame is a licensed gas contractor; we pull the Henderson County permit, pressure-test the line, and back the repair — mindful of the home's age and finishes. A brief whiff at ignition can be normal; a lingering rotten-egg smell with the fireplace off always gets a pro. Call (828) 545-0525.
