Fireplace Servicesin Mount Prospect, IL

At least once a year if you burn regularly — and sooner if you burn most evenings through a Mount Prospect heating season. Steady wood fires lay down creosote, and the glazed kind builds fastest from slow, smoldering fires. Cleaning removes that buildup before it can ignite, and the visit also checks the liner, cap and damper.

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.

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.

Do not light a fire. Raccoons and birds nest in open flues through spring and summer in Illinois, 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.
