About This Service
Confirm Fit Before Choosing the Product
Outlet shape, dimensions and fitting method determine cap selection. A photograph can suggest a style but cannot confirm compatibility. Twin assesses the termination before specifying the replacement; homeowners can describe the concern from the ground and leave elevated measurements to the service visit.
Include Safe Access in the Plan
Chimney position, roof shape and access restrictions affect the replacement plan. Mention locked access or other constraints when scheduling. Twin plans the elevated work and discusses any effect on scope before approval; homeowners should not remove the old cap or prepare the roof.
Keep the Replacement Details
Keep the installed cap identification and completed scope with your chimney records. They help a later visit identify the actual part. Retain any unresolved surrounding condition too: a cap replacement receipt should not imply that the passage, roof junction or entire chimney was repaired.
Confirm What Custom Fabrication Includes
A custom cover still needs a defined fit and application. Ask which openings, attachment and supporting conditions its specification addresses. The fact that a piece is fabricated to measurements does not automatically establish that it is appropriate for the connected chimney system.
Keep the Specified Part With the Service Record
Retain the product identification and which chimney received it. On a later visit, these details are more useful than remembering the cover’s color. The record should also preserve any supporting repair or unresolved condition discussed when the replacement was agreed.
