Document from safe ground
Share visible deterioration or interior moisture history without climbing onto the roof. The contractor must assess the top directly using a safe access method; a ground-level photograph cannot establish every defect.
Ask whether a coating is appropriate
A surface product and a rebuilt crown are different scopes. Ask why the proposed approach fits the condition and what defects it will not address. Product selection should follow the substrate condition and instructions.
Look at adjoining parts
The top of the stack, flue openings and cap may affect the investigation. Ask which interfaces are covered and whether masonry repair is separately priced. Water can have more than one entry point.
Plan curing and access
Ask about weather restrictions, protection during the work and when follow-up checks are appropriate. A rushed promise to complete work regardless of conditions deserves clarification.
Keep photographic handover evidence
Request clear before-and-after views and a written description of materials and exclusions. If water staining continues, keep a dated record and arrange follow-up rather than assume the interior stain identifies the remaining cause.

Questions answered
Chimney service FAQs
When should I ask about chimney crown repair?
The crown is the top surface of a masonry chimney around the flue openings. Cracks, deterioration or an unsuitable prior repair can warrant assessment. A crown and a rain cap are different components and should be named separately in a proposal.
What should be recorded before work starts?
Share visible deterioration or interior moisture history without climbing onto the roof. The contractor must assess the top directly using a safe access method; a ground-level photograph cannot establish every defect.
What should I keep after the visit?
Request clear before-and-after views and a written description of materials and exclusions. If water staining continues, keep a dated record and arrange follow-up rather than assume the interior stain identifies the remaining cause.
