Symptom field note
Poor chimney draft
Fires are difficult to start or smoke does not move steadily up the flue.
Stop using the appliance if smoke spills into living areas.
What might be behind it?
Several conditions can produce similar symptoms. These are possibilities for a professional to investigate, not a remote diagnosis.
An obstruction, cold flue, vent sizing, appliance condition or pressure in the home may contribute.
A recent change in windows or exhaust equipment is worth telling the contractor.
What to document before calling
- Which fuels and appliances are involved
- Weather and fan use when the problem occurs
- Any changes to the home or vent system
Take photographs only from a safe position. Avoid roof access, opening a vent or continuing to operate a suspect appliance to reproduce the problem.
Practical next step
Ask for a draft and venting diagnosis before buying a fan, cap or other proposed fix.
Describe the symptom first, then ask the company which inspection or service they recommend and why. Request written findings before approving major repair work.
Questions for the company
- Do you work on my fuel and appliance type?
- Which possible causes will your assessment check?
- What areas are inaccessible and how will you document them?
- Will the report include photos, limitations and a separate repair scope?
