To prevent any leakage of fumes from the 4 flues within the chimneybreast into the new room the brick chimneybreast party wall had to be coated with a mortar render. The process of coating the wall with the mortar is known as parging.
Parging is a fairly easy and straighforward DIY job, particularly as the finished wall will be hidden behind an insulated and plasterboarded partition. The most difficult bit of parging is carrying the many buckets of mixed mortar up into the loft (or alternatively, carrying all the bags of sand and cement and buckets of water up into the loft).

| There was a small gap at the top of the brickwork between my neighbour's loft and mine (barely big enough to put a finger in). This gap was filled with fire retardent expanding foam to reduce the risk of fire breaching the party wall in any direction. |

| Not a great picture, but that's the job done. Yes, the chimneybreast is an odd shape, however it'll eventually be behind an insulated partition, so who cares! |
