What to put in the scope
- Assess cracks, surface condition and water-shedding details.
- Specify preparation and whether the work is a repair or replacement.
- Explain how adjacent flues and masonry will be protected.
Where this service stops
A crown repair does not resolve every leak. Flashing, cap details, roof problems and condensation may require separate investigation.
The evidence to keep
Ask for photographs of the existing crown and a materials-and-method description. Keep cure, weather and follow-up conditions with the warranty.
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 shows that repair is appropriate rather than replacement?
- Is water entering elsewhere too?
- How will the finished crown be checked?
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.
