What to put in the scope
- Take a history of when the symptom appears without recreating an unsafe event.
- Assess the appliance, vent and relevant building conditions.
- Explain findings and any tests or further access required.
Where this service stops
One accessory cannot be assumed to cure every draft problem. Do not use this guide as clearance to operate a smoking appliance.
The evidence to keep
Record the timing of previous symptoms, appliance details and which fans were operating. Ask the professional to separate observed facts from possible causes.
Record who performed the work, the date, the identified appliance or flue and any follow-up recommended. When photos are provided, ask for labels that let another contractor understand what they show. A clear record helps distinguish a new condition from an old recommendation at the next visit.
Questions before accepting a proposal
- What evidence supports the proposed cause?
- Are building pressure effects being considered?
- What must be resolved before reuse?
Ask the company to identify travel, roof access, additional flues, permits and disposal separately where they affect the price. Confirm how unforeseen conditions will be explained and authorized. Keep the original estimate alongside any agreed changes.
