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.
Do Not Assume an Unused Opening Is Abandoned
A flue that has not been used recently may still be part of an installed system. Ask for its role to be established before a cover arrangement changes it. Capping for weather protection and permanently closing a passage are different projects.
Name the Features in the Selected Product
Rain protection, screening and spark-arresting functions should not be assumed from the word cap alone. Ask the proposal to identify the intended product and features. The suitable arrangement depends on the connected system and applicable requirements, not an improvised mesh choice.
Assess Noise Before Replacing Parts
A rattling sound can be useful to describe, especially if its timing is consistent. It does not locate a loose fastener or establish which part is vibrating. The inspection should connect the observed condition with the proposed work rather than order a replacement on sound alone.
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.
