Diagnose first.
Then quote.
Most hearth problems have more than one plausible cause, so we test before recommending work.
Inspect the complete system
Appliance, flue, termination and surrounding structure—not just the visible fault.
Separate the findings
Safety items, repairs to plan for, and conditions that only need monitoring.
Make the quote comparable
Parts and labour are clearly described so you can make an informed choice.
