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.
Account for earlier patches
The type and location of an earlier patch may influence the current condition. Share records or an accessible photograph if available. Twin assesses surrounding materials and explains whether the proposed work corrects the failed detail, removes unsuitable material or addresses a separate concern.
Keep weather observations factual
Describe the circumstances you personally observed rather than assuming a particular wind or rain pattern proves the cause. Twin considers that history alongside the installation. A service-area address alone does not establish exposure, construction or the source of a leak.
Match Junction Work to Surrounding Materials
Roof coverings and chimney construction can affect the detail being repaired at their intersection. Identify the materials actually present before treating an example from another property as the specification. Twin explains the relevant chimney work and any separate roof scope needed to address the connection coherently.
Give Shared Chimney Tops a Clear Scope
Several openings at one chimney top do not necessarily make one component replacement the complete job. The proposal should identify each included termination and any common cover or supporting repair. That avoids mistaking a quote for one fitting as work on every visible flue.
