About This Service
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.
Use records to clarify prior work
A previous estimate can identify whether flashing, masonry or a chimney-top component was actually repaired. Share it when available. That distinction helps avoid attributing a later symptom to a component that was never part of the earlier scope.
Explain Intermittent Moisture Honestly
A leak that is not active during the visit still needs a clear history. Describe when water was actually observed and whether a stain changed between events. The absence of visible water at one moment is not proof that the concern is resolved, but the pattern alone does not justify a specific repair either.
Do Not Equate Mesh With Water Protection
A screen or mesh component and the top of a cap perform different roles within the fitting. Damage should be assessed as part of the complete cap and termination. Replacing a screen alone is not evidence that a crown, flashing or other water-entry concern has been corrected.
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.
