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.
Review masonry defects before coatings
BIA guidance treats investigation and correction of defects as part of addressing water penetration. A water-repellent treatment is not a substitute for repairing failed joints or other defects. We discuss whether the material and condition support a treatment after the underlying concern is understood.
Describe the Replacement Metal
When a cap or cover is replaced, material and configuration belong in the proposal along with removal and attachment. A photograph of a similarly shaped product is not a full specification. Ask which component is being supplied and whether any supporting work is required before it is fitted.
Do Not Rule Out a Concern From Appearance Alone
A chimney can look intact from the ground while a reported water issue still needs assessment. Conversely, a visible surface mark does not establish hidden damage. Explain the actual observation and let the scope of inspection determine what can be established about the relevant components.
Separate Condensation Questions From Rain Entry
Dampness near equipment should be described without assuming it is rainwater from the chimney top. The timing, location and installed system can lead to different assessment questions. Twin discusses whether the proposed chimney repair addresses the observed concern or whether another cause remains to be investigated.
