About This Service
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.
Distinguish an Outside Mount From an Insert Fit
Manufacturers offer caps that fit differently around or within an outlet. Those arrangements are not interchangeable descriptions of the same product. The assessment should identify how the proposed fitting meets the actual termination, while the product instructions control its installation.
Identify Unusual Outlet Shapes
A nonstandard-looking termination should not be forced into the closest familiar product size. Its shape and system identity need assessment. Keep an available model or old part description for the visit; final fit should be established at the outlet rather than inferred from the ground.
Report Material Around the Screen
Visible material near a screen warrants assessment of what is present and why. Do not reach into it or assume it is harmless debris; nesting activity and accumulated deposits need different handling. A replacement plan can follow once the relevant condition is understood.
Review a Customer-Supplied Component
Share the exact product information for a cap you already own. It may help the assessment, but the installation should not proceed on the assumption that purchase established suitability. If it does not fit the application, discuss the alternative before work is booked.
