Pointing is the process of replacing deteriorated mortar in the joints of a masonry wall with new mortar. Older properties pre-1940's will have to use a NHL 3.5 lime mortar after that normally a blend or gauged mortar which has sand cement and lime in the mix. If your property has disintegrating mortar, cracks in mortar joints, loose bricks or stones, damp walls or damaged plasterwork then you need repointing.

The Pointing Process Explained
We grind to remove old mortar using diamond disk (not resin) to a depth of twice the width, often using 6.5mm thick mortar raking disks. If it has not been raked out deep enough then it will fail and need to be redone.
After mortar has been removed, we jet wash/hose down to remove excess dust. Repointing will be either Sand & Cement or Lime, to a colour of your choosing (samples available)
Repointing will be carried out by dampening the walls first and repointing with a measured mix from the top of the building working down.
There are 2 finishes available - Flush and Weather Struck
Weather Struck Finish
This process is used to clean up poor repointing (as image below). The finished result is much more visually appealing.

Incorrect strength of pointing mix is damaging to brickwork and costly to repair. The damage as seen below can happen in as short a time period as 2 years. This can be avoided by commissioning an expert pointing specialist.
