A chimney cap closes off an unused stack to prevent water ingress while maintaining ventilation. An unventilated sealed stack traps moisture inside the flue, causing internal damp and eventual structural damage — so simply bricking over or sealing a disused chimney is rarely the right answer.
At Trust Roofing Services, we fit vented caps that keep rain and debris out while allowing the flue to breathe. We are a family-run team based in Hucknall, NG15, with over 15 years of experience across Nottingham and Nottinghamshire.
How We Fit a Chimney Cap
We inspect the stack and flue condition first — capping over an already-deteriorating stack doesn't solve the underlying problem, so we address any mortar or flaunching issues before fitting. The cap itself is fixed and sealed using a method that keeps the flue vented rather than fully sealed, since a completely sealed stack traps moisture that causes damage from the inside. The correct fixing matters — a cap that allows water to track around the edge defeats its purpose.
Frequently Asked Questions
Should an unused chimney be capped or fully sealed?
Capped, not fully sealed. A vented cap keeps rain and debris out while still allowing the flue to breathe. A fully sealed stack traps moisture inside, which causes internal damp and structural damage over time.
How much does chimney cap installation cost in Nottingham?
Cost depends on stack height, access, and whether any repointing or flaunching repair is needed first. We provide a free, itemised quote after a survey.
Can birds still get in after a cap is fitted?
No, a correctly fitted cap combined with a bird guard where needed keeps birds, debris and rain out while maintaining ventilation.
