Left uncapped disused chimneys are prone to a number of serious problems arising from exposure to the elements and blockage by nesting birds. Fitting a cap provides instant protection against these problems, potentially saving hundreds of pounds on costly repairs.
Below are just a few examples of the many dozens of chimney terminals that are on the market. It is vital that the correct terminal is fitted. An inappropriate terminal may cause the chimney to operate incorrectly and inefficiently which may not only cost you financially but can also lead to poisonous fumes from your fire not being expelled and putting your family at risk of carbon monoxide poisoning.
