How do I check my gas fireplace for a gas leak?
Your two homeowner tools are your nose and a plug-in gas alarm — anything beyond that belongs to a licensed gas contractor with an electronic leak detector and a manometer. If you're smelling gas right now, treat it as a confirmed leak and follow the leave-and-call protocol; that's not a moment for a do-it-yourself check. Real leak testing means pressure-testing the whole line, and we do that on every inspection.
What you can safely watch for yourself
Plenty, actually — none of it involving tools. The rotten-egg odorant is your first line; take any persistent whiff seriously. Listen for a faint hiss near the fireplace when everything is off. Watch the appliance's behavior: a pilot that keeps dying, a lazy or discolored flame, soot appearing on glass or logs. Outdoors, a patch of dead grass over a buried line or a propane bill that's crept up without explanation is worth a call. And in propane homes especially — Fairview, Candler, Brevard, the cabins — a combustible-gas alarm mounted low on the wall earns its keep, because LP pools at floor level where your nose spends the least time.
Why we won't hand you the soap-bubble tutorial
You'll find the dish-soap trick all over the internet, and here's our honest problem with it: it only reads the one fitting you can reach, while most of your gas system runs through walls and crawlspace where no spray bottle is going. Worse, a bubble at a joint tempts people to grab a wrench — and tightening or remaking gas connections is licensed work in North Carolina, easy to make worse and illegal to freelance. A real check is a pressure test of the entire run with a manometer, plus an electronic sniffer at every accessible joint and the appliance's own valve and pilot assembly. It's quick, it's definitive, and it's quoted upfront.
The once-a-year answer
The best leak check is the one that happens before you suspect anything: an annual service visit covers the connections, the valve, and the burner as a matter of routine — late summer or early fall, before you're depending on the fireplace. If something specific has you worried today, call (828) 545-0525 and we'll put instruments on it.
