Chimney Leaks

Water leaks relating to the chimney are quite common as a property ages or following other works that have disturbed something within the chimney. Leaks can travel away from their source confusing customers as to the reason behind the leak.

A leaking chimney usually presents itself to the homeowner in the following ways: peeling wallpaper, a damp patch on or near the chimney breast (at any level of the property), water in the fireplace, dripping noise in the chimney, rust on your fireplace grate or flue pipe.

It is not unusual to hear from customers who have had remedial works carried out to their chimney stack by a third party, to then find that the leak persists. In these cases, we are able to use our many years of experience to offer a suitable resolution. We also have specialists to undertake areas such as leadwork which can cause further issues when poorly installed by an unqualified individual.
