About This Service
Separate old stains from active entry
Discoloration can remain after a past event. Tell us whether it is changing and what has already been repaired. The assessment should not use an old mark alone as evidence that the same water path remains active or that the previous work has failed.
Check the installed top assembly
The top configuration affects how a cap, cover or other component is fitted. Twin discusses the existing assembly before recommending replacement. A new part should correspond to the installed construction, rather than being selected only because its appearance resembles the old piece.
Distinguish the Outside Surface From the Passage
Moisture reported on the exterior chimney and water appearing inside the fireplace are different observations. Tell us which you have seen and when. They may prompt assessment of different components, so the repair proposal should not assume that a treatment on an outside wall answers a concern inside the connected system.
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.
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.
