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 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.
Keep Interior and Exterior Observations Paired
A photograph of the indoor stain and an existing image of the outside chimney can describe different parts of the same request. Neither establishes the whole water path. Keep their dates and locations clear so the assessment does not compare an old condition on one surface with a new observation on another.
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.
Recognize a Separate Building Leak
Water visible near a chimney may require assessment of adjacent building elements as well. The chimney service scope should identify its boundary instead of promising to resolve every source in the surrounding structure. If another trade is needed, that next step should be discussed before interior restoration is treated as complete.
