About This Service
Track where moisture appears first
The first visible location and timing can help frame the assessment. Explain whether the symptom appears during rain, afterward or under another condition. Those details remain observations, not proof that the component closest to the stain is the source of the leak.
Distinguish cap from crown
A cap and the masonry crown are different chimney-top components. A missing cap does not establish that every leak originates at the opening, and a cracked crown needs its own assessment. The repair scope should name the part being corrected and explain its relationship to the reported concern.
Separate old stains from active entry
Discoloration can remain after a past event. Tell us whether it is changing and what has already been repaired. The assessment should not use an old mark alone as evidence that the same water path remains active or that the previous work has failed.
Avoid promising a universal leak fix
No single chimney product resolves every possible source of water entry. Twin explains the condition the proposed work is intended to correct. If additional investigation remains necessary, that uncertainty should be part of the discussion before a repair is represented as complete.
Discuss the handover
After the accepted work, keep the description of repaired components and any remaining recommendation. That record is more useful than a general statement that the chimney was serviced. It helps future maintenance address the correct location and installed detail.
