Practical Roofing provides Chimney Repointing services. A Chimney Stack must be kept in good condition to enable it to be weatherproof.
Ineffective pointing can lead to rapid deterioration in damp conditions which may lead to expensive work such as having the entire stack rebuilt.
Chimney stacks have to bear the brunt of the British weather, the ice and frosty nights combined with the heat from your fire create a harsh ‘freeze & thaw’ Cycle, only to be further eroded by strong winds and rain.
Repointing is a great way to repair and revitalise the appearance of your property, re-bedding chimney pots can also greatly improve the efficiency of your fire, as well as the obvious safety improvements, and avoiding further damage to your property caused by a chimney pot/stack collapsing.
Inside- Water staining on the ceiling or around the chimney breast or even lower down near the fireplace itself. If it is lower down the building the problem could be due to the flue and the fireplace will need to be completely sealed. Dampness inside of the home can sometimes indicate problems with the Chimney Stack itself.
Outside- Broken, cracked pots or cracks in the mortar. Also look for mortar missing from between the bricks. If the stack is not in the vertical position and leaning.
