About This Service
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.
Keep roof investigation professional
Do not climb onto a wet roof, remove a cap or dismantle flashing to investigate a leak. Describe observations from a safe position and share photographs already available. The visit should plan the access needed to inspect the relevant details.
Distinguish component repair from a rebuild
Localized damage does not automatically require rebuilding an entire chimney. Conversely, a cosmetic patch is not a substitute for a broader repair when the condition calls for it. We explain the extent of the proposed work and the findings that support it.
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.
Leave Temporary Roof Covering to the Work Plan
Do not climb onto the roof or seal a termination to improvise a temporary cover. Such changes can introduce a different problem at the installed system. Keep the affected fireplace unused and discuss access and interim arrangements with the service contact while the repair is being planned.
