Point – to fill new masonry joints with mortar or to correct defects in existing joints
Repoint – to fill cut or raked masonry joints with mortar usually due to deterioration
Tuckpoint – to fill masonry joints with a flush mortar matching masonry units color and add a thin strip of contrasting mortar on top

Repointing of deteriorating mortar joints minimizes moisture penetration of your brickwork.
A typical mortar joint should last at least 25 years before requiring any repairs. However, its lifespan depends on the mortar mix itself and the property’s geographical location / weather conditions.

• Cracks in mortar lines between the bricks
• Crumbling mortar / loose pieces of mortar falling from between the bricks
• Mortar erosion greater than 6mm deep (1/4”)

Ideally this should be determined in a laboratory by examining and matching of the existing (old) mortar mix sample proportions. This would prevent often irreparable brick damage caused by repointing with a mortar mix that has stronger compressive strengths than the original mortar mix.
