Grade II listed chimney restoration

---

This chimney appears to have been rebuilt at some stage in the past, perhaps when the original property was split into separate domestic properties. The condition of the chimney was quite poor, with failed mortar joints, damaged bricks and a missing chimney pot which came down in a storm.

The right hand flue serves a bedroom fireplace which is intended to be brought back into operation. The left hand flue serves a woodburner on the ground floor. The flaunching was carefully removed along with the metal mesh. The stack was raked out and loose bricks were removed. The stack was then rebuilt and repointed. Reclaimed bricks were sourced locally. Reclaimed pots were also sourced and fitted onto galvanised steel sheets. Some of their previous mortar remains on the bottom - as much was removed as possible without breaking the pots. The chimney was flaunched. Natural hydraulic lime 3.5 was used for this job. NHL 5 is often used for chimneys but I consider this to be too strong a binder for historic buildings, resulting in an excessively high compressive strength.
