Fireplace Servicesin Sturtevant, WI

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.

Do not light a fire. Raccoons and birds nest in open flues through spring and summer in Wisconsin, and a nest blocks the draft and holds moisture against the liner. Lighting under a blockage pushes smoke and carbon monoxide into the room. We remove the blockage, check the flue for damage, and fit a screened cap.

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.
