Illustrative scenario. This is not a documented customer project, testimonial or confirmed diagnosis.
What an inspection might investigate
The professional would consider chimney condition, obstruction, appliance setup and how the house moves air. A ventilation specialist may be needed alongside chimney assessment.
A possible service path
Stop fireplace use and write down the sequence of changes. Request investigation before approving a taller chimney or replacement cap. Do not run trial fires with different fans to test an idea.
The homeowner's question
How will you distinguish a chimney defect from an air-supply or pressure problem?
What a useful outcome would contain
A dated report, clearly identified findings and an explanation of unresolved questions are more useful than a reassuring phrase. If further work is recommended, the homeowner should receive a scope that separates investigation, repair and restoration. This example does not assume any particular finding or successful outcome.
Take the service question to your location
Use the local guide to prepare questions about access, building history and the authority responsible for your address. The service brief is national guidance; local permits and current burn restrictions must be checked separately.
