Chimneys are at the highest point of a property, and therefore, open to all the weather elements.
Chimneys need to be checked as the mortar will, over time, crack and crumble an allow voids between the bricks to become loose and in the worst case scenario the chimney may fall causing roof damage or fall on to vehicles or people if they are close to the property.
Re-pointing the chimney may be all that is required to stabilise it.
Re-pointing is the cheaper option.
Chimney Crown – The top of your chimney is called the “chimney crown.” It is designed to protect the chimney’s bricks from impairment such as water damage.
Chimney crowns are usually constructed of cement.
