What to put in the scope
- Determine whether masonry is suitable for the proposed product.
- Resolve repairs and specify cleaning or preparation first.
- Record product, application area and manufacturer conditions.
Where this service stops
Coatings cannot restore unstable masonry or repair flashing. The proposal should address moisture movement and material compatibility rather than promise a sealed chimney.
The evidence to keep
Retain product identification, prepared areas, application date and maintenance instructions. Ask what evidence supports choosing a treatment.
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 defects must be repaired first?
- Why is this product appropriate for the masonry?
- Which water-entry paths will this not address?
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.
