Start with what your chimney is doing.

These guides help you describe a problem and request the right investigation. They do not diagnose a chimney remotely.

For active fire, a carbon-monoxide alarm or immediate danger, leave the building and contact emergency services.

Smoke coming into the room

Record whether smoke appears during lighting, steady burning or refueling, and whether exhaust fans were running. Do not repeatedly light fires to recreate the symptom.

Water in the fireplace

Photograph the first visible wet area and note rainfall, wind direction and whether the appliance was operating. Keep the roof inspection for a professional.

Persistent chimney odors

Note when the smell occurs, whether the weather is damp and whether fans or heating equipment are operating. Carbon monoxide has no smell: odor cannot rule it in or out.
