Repointing brick mortar


What is Pointing?


The term pointing can be defined as the finishing of mortar joints located between brick or stone. As we’re very proud to repeat, masonry materials last a long time. Brick and stone are durable, and they don’t damage easily. Unfortunately, the mortar between these materials doesn’t last as long, and it requires maintenance to keep the structure’s integrity intact.


Repointing is the process by which masons remove deteriorated or damaged mortar from the joints and replace it with new mortar. Not only will repointing improve the stability of the structure itself, but it will also benefit the aesthetic appeal of your stone or brick as well.


Though repointing is beneficial, it is not an easy remedy to any lingering structural deficiencies your home might be suffering from. It’s important to find the source of the problem you’re experiencing before assuming a repoint job will fix it. Ask your local masonry professional to take a look at the area before planning any work.

What’s the Process?

1. Examination/Consultation
Before starting any work, a proper examination of the structure must be conducted in order to assess the extent of repointing that needs to be completed as well as the damages that might have resulted from the eroded mortar.

2. Obtain Materials
It’s always a good idea to try to match the new materials as closely as possible with the old ones. You don’t want the repaired area to stick out in any way and cause any aesthetic dissonance on the exterior of your home.
It’s also important that the mortar you use has similar characteristics to the original mortar used. This way the old and new joints share the same give. If you use stronger mortar for one section that section might not give into structural stresses that the other section will, resulting in cracks.

3. Remove Old Mortar
Next the mason starts the process of removing the old mortar from the joints. After removal it’s important to clean the joints before filling them with new mortar.

4. Apply New Mortar
First the mason will fill the areas with the deepest recessions, and then they will continue to apply the mortar in several layers. The mortar should be manipulated using the proper tools to imitate your desired style.
