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.
Identify Every Termination Being Covered
An individual flue cap and a cover spanning multiple outlets protect different arrangements. Have each opening included in the estimate identified. A price for one fitting should not be read as replacement of every cap or cover visible at the chimney top.
Coordinate Supporting Repairs
Crown damage or a deteriorated flue top can require repair before attachment. Ask which task creates a suitable base for the cap and which addresses a separate defect. A combined estimate should show the sequence and price, with additional findings discussed before expanding the work.
Know Where a Top-Mount Cover Attaches
A cover mounted across the chimney top needs its attachment surface identified. The proposal should distinguish that arrangement from a cap fitted directly to one flue. If the surface is damaged, supporting repair belongs in the decision before the new cover is installed.
Identify the Available Mounting Surface
The visible outlet may not provide the same mounting surface as the product shown in an online example. Selection should follow the actual termination and relevant instructions. Ask which part will carry the attachment and whether additional component work is needed.
