Symptom field notes
Water or staining around the fireplace
A useful leak investigation starts with the timing and location of moisture. Visible staining does not identify the entry point on its own.
Do not climb onto the roof to trace a leak or apply a product before the cause is assessed.
What to document
- Where does water first become visible?
- Does it follow wind-driven rain, prolonged rain or appliance use?
- Which prior repairs are documented?
Keep dates and observations separate from guesses about the cause. Photographs from a safe location and earlier service records are useful starting material.
What to ask the contractor
- Which chimney and roof components are within your inspection scope?
- What evidence connects the proposed repair to the source?
- How will you document completion and follow-up?
Ask for findings, access limitations and recommended next steps in writing. A proposed product or repair method should follow an explanation of the observed condition.
From symptom to evidence
Separate the visible stain from the proposed entry point
A ceiling stain and a photograph of a worn chimney component are two observations; the proposal should explain the connection between them. Ask whether the visit includes the chimney top, roof junction and accessible interior evidence, or whether a second trade needs to assess part of the route. This prevents paying for several unrelated treatments without a clear investigation record.
What a useful assessment record includes
- Record when moisture appeared and whether the area had already dried before the visit.
- Ask the contractor to locate the suspected entry point in a labelled photograph.
- Request a follow-up plan if water returns after the agreed repair.
Should I choose a waterproofing package first?
Ask what documented condition the package addresses and what it excludes. A treatment quote is not itself a diagnosis. Compare a proposal for leak investigation with another investigation proposal; compare a repair only after its target component and evidence are clear. Ask who coordinates roof work when it falls outside the chimney company’s scope.
Related observation: Cracked chimney crown. Similar observations do not establish the same cause.
Turn the observation into a comparable scope
Send the same brief to each company. Ask whether the appointment is an inspection, a diagnostic visit or a repair, and how additional work is approved. If proposals disagree, compare the evidence each contractor cites before comparing totals.
