Smoke and draft assessment: the homeowner scope manual

Stop unsafe operation

Stop using the affected appliance. For accumulating smoke, a carbon-monoxide alarm or a fire concern, leave the property and contact emergency services. Do not use open windows as a substitute for a repair.

Describe the sequence

Record which appliance operated, when the symptom appeared and whether building or appliance work occurred beforehand. Do not recreate the event to gather evidence. Existing observations are enough to start a booking conversation.

Ask about assessment scope

Clarify which components and operating conditions the professional will evaluate. The contractor may need another qualified trade if the concern extends beyond chimney work. Ask how findings and limits will be documented.

Evaluate a proposed modification

Changing a cap, extending a chimney or adding equipment should follow an explanation of the problem. Ask how the proposed change addresses the findings and what compatibility or approval checks are needed.

Get clear reuse guidance

Ask which conditions must be resolved before reuse and what follow-up is required. Keep the report and repair record together so the next technician can understand why changes were made.
