Start with what you notice.
Find a sensible next step for leaks, smoke, masonry damage, and fireplace concerns. If there is an active emergency, leave the building and call emergency services.
Chimney leaking
Water around a chimney needs a source investigation. A stain inside the home does not identify which exterior component has failed.
Read the next steps Problem solverSmoke backing into the house
Smoke entering a room is a reason to stop using the fireplace. Leave immediately if there is a carbon monoxide alarm, significant smoke, or anyone feels unwell; call emergency services from outside.
Read the next steps Problem solverWater in the fireplace
Water in a cold fireplace can arrive through several paths. Keep the appliance unused and arrange an inspection of the system and adjacent water-shedding details.
Read the next steps Problem solverCreosote smell
An odor is a useful symptom to report, but smell alone does not identify the material or prove the chimney is safe. Arrange a professional assessment before further use.
Read the next steps Problem solverChimney cap missing
A missing or displaced termination needs professional assessment and a compatible replacement. Keep clear of loose components and the area below the chimney.
Read the next steps Problem solverChimney masonry cracking
A crack needs context: location, movement, water entry, and the surrounding masonry. Widening cracks, leaning, or loose masonry call for keeping clear and prompt professional evaluation.
Read the next steps Problem solverFlaking or spalling brick
Flaking brick is a symptom of deterioration, not a reason to cover the surface immediately. Ask for the moisture source and material condition to be assessed before choosing a treatment.
Read the next steps Problem solverWhite staining on chimney brick
White deposits need identification and a moisture assessment. Cleaning the visible mark alone may leave the cause unresolved.
Read the next steps Problem solverAnimal sounds in the chimney
Do not light a fire to remove an animal. Leave the fireplace unused and contact a qualified professional who can coordinate with an appropriate wildlife specialist and local requirements.
Read the next steps Problem solverFireplace damper stuck
A damper that does not operate normally is a reason to leave the fireplace unused. Do not force the mechanism or light a test fire.
Read the next steps Problem solverCold draft from the fireplace
A cold draft is a comfort symptom that needs the system type and airflow path identified. Do not block a vent or seal a component that serves an appliance.
Read the next steps Problem solverFireplace will not light
Leave a malfunctioning gas fireplace unused and arrange model-specific diagnosis. If gas is suspected, leave and contact emergency help from a safe location.
Read the next steps Problem solverPilot light will not stay on
Repeated pilot failure needs professional diagnosis. Do not bypass a safety control or keep attempting ignition.
Read the next steps Problem solverGas fireplace shuts off
Unexpected shutdown may indicate a fault or a safety response. Leave the appliance off and ask a qualified technician to inspect it.
Read the next steps Problem solverSoot or black staining
New or unexplained black staining around a fireplace should be assessed before reuse. Treat an alarm, illness, or active smoke as an emergency.
Read the next steps Problem solverSuspected chimney liner damage
Debris or an inspection report may raise a liner concern, but the repair depends on the actual system and defect. Keep the connected appliance unused pending qualified advice.
Read the next steps Problem solverChimney odor in summer
A warm-weather chimney odor can have several causes. Record the weather and timing, and have the chimney assessed instead of masking the smell.
Read the next steps Problem solverIce and freeze-thaw damage
Moisture exposure and repeated freezing can contribute to masonry deterioration. Visible damage deserves a site-specific assessment; the weather alone does not diagnose the repair.
