What is pointing — and why does it fail?
Pointing is the external part of the mortar joints laid between the bricks or flint work of a building. It must perform several vital functions including the prevention of water penetration, while allowing the wall to breathe. Age, weathering and decay are some of the contributing factors that can lead to joint voids where water may penetrate and a mortar repair, also called repointing, becomes necessary.
Repointing not only restores the integrity of the brickwork, but significantly improves the cosmetic appearance of the building.
It’s crucial that the mortar used for repointing has similar performance characteristics to the original mortar. Strength and permeability must be assessed; for example, if a hard mortar repair is used on soft bricks, the bricks will degrade faster — and will be expensive to rectify.
Part of our initial professional assessment involves taking samples of the mortar to ensure that the correct sand and binder are used, as well as ensuring that the repointing is matched as closely as possible to the original pointing mortar.
The pointing process: what’s involved?
The old mortar must be removed by a minimum of 20mm, ensuring that all mortar is removed to the top and bottom of the joint. We use 5″ angle grinders equipped with diamond mortar raking blades and dust extraction hoovers. If the use of power tools is inappropriate for the building, hand repointing tools including comb hammers are used.
The walls are then washed down to remove all loose dust from the joints in preparation for pointing. When applying the new mortar, the use of a traditional hawk and trowel means highly-efficient application into the joint, ensuring there are no voids; the mortar is then shaped to the required finish.
Different pointing mortar finishes
Our highly-skilled team can offer a number of brick pointing styles to enhance a mortar repair:
· Flush: a nice flat finish to the face of the brickwork (generally seen on old lime mortar properties)
· Bucket Handle (compressed rubbed finish): a concave finish used on properties since the 1950s
· Recessed: this flat finish is recessed by 3mm from the face of the brick
· Weather struck pointing: a popular style that is slightly angled and cut on the brick edge
· Bird’s beak: a popular style on flint work that is angled on both sides to create a bird’s beak point in the centre of the joint
· Tuck pointing: a Victorian style of pointing that hides large and uneven brick edges. The mortar joints are coloured to match the brickwork, followed by the skilled application of a lime putty ribbon for a perfect, straight narrow joint
Listed building repointing in Oving
This listed property In Oving, West Sussex had previously been given a poor mortar repair with a strong sand and cement mix. After careful removal of the old mortar, repointing was carried out using pre-mixed lime mortar to a bird’s beak finish.

Repointing flint work in Brighton
We were asked to repoint the flint walls of a crematorium in Brighton. The lime mortar was carefully removed to a depth of at least 20mm using comb hammers, then repointed using a 3:1 lime mix (3 parts black sand: 1 part natural hydraulic lime).
