Water soaks into a crown, a mortar joint or porous brick, then freezes and expands, prying the opening wider each time. Over a few Midwest winters that cycle spalls brick faces, splits crowns, and crumbles mortar joints, and the gaps let more water in. Catching it early is a repair; ignoring it becomes a rebuild.

Usually the thermocouple or thermopile. Those sensors sit in the pilot flame and prove heat before the main burner is allowed gas; when they wear out, the valve shuts the pilot down as a safety measure. Dust in the pilot orifice can starve the flame and cause the same symptom, so we clean and test before replacing parts.

From the room, usually you cannot — cracked tiles are inside the flue, above the firebox. Signs can include smoke smell in upstairs rooms, pieces of tile in the firebox, or a fireplace that drafts poorly after years of good service. An inspection with a flue camera shows the tile condition directly and gives you a plain-language report.

Real enough that cleaning is scheduled around it. Creosote builds on flue walls with every fire, and a hot fire or a stray spark can ignite the glazed layer, turning the flue itself into a fire that cracks liners and damages masonry. Annual cleaning, burning dry wood, and keeping fires hot rather than smoldering all lower the risk.

Idle months are the usual cause. Dust settles in the pilot orifice, insects reach the burner ports, and a thermocouple that was already tired gives up while the unit sits through humid summer weather. Most fall no-light calls are one small part or a thorough service — cleaning, pilot and burner checks, and a test fire before we leave.

No — and be wary of anyone who does. Every fireplace fails differently, so a phone price is a guess that changes at your door. Our estimates are free: a tech looks at the actual problem, then gives you one clear price before any work starts.
