When called out to repair chimney stacks a common problem is eroded pointing. In itself this may not sound too serious, but if neglected it will hasten the onset of more serious problems such as instability, water penetration and even disintegration. In the case with this job loose flaunching needs to be completely hacked off and replaced with a suitable mortar mix, waterproofed and carefully moulded so it slopes outwards to disperse rainwater.
We also repaired the flashing down the side of the chimney with the mortar mix.
