Why cap disused chimneys?

Heat Loss

A disused chimney provides a route for heat loss, which can be minimised by capping-off a chimney, as recommended by the Energy Saving Trust.

Protection from the elements

Over the course of a year the UK weather can in general be relied on to deposit the equivalent of several ft depth of water into an uncapped chimney, where combined with the effects of frost action through the winter months it causes a steady internal deterioration of the fabric of the stack, and can give rise to major internal damp problems.

Nesting birds

Any unprotected chimney is prone to blockage by nesting birds which traps moisture in the chimney and blocks ventilation which prevents it drying out, they also cause an unhygienic mess.


In some areas grey squirrels present a real problem, potentially trapping themselves in an unprotected chimney where they can gain access to a home where serious damage can occur.
