What Is Repointing and Why Do I Need It?
Repointing is the act of carefully replacing masonry joints. Do you have brick or stone walls where the mortar is missing or crumbling? You need repointing to avoid water infiltration that could harm the sides of your building.
Remove Damaged Mortar
Our repointing procedure is done according to best industry practices. It is essential to remove about 1 inch to 1½ inches of unhealthy mortar using electric grinders, then fill the empty joints with a mortar specially formulated for repointing. Once the result is dry, we do a good cleaning with water and a low concentration of acid detergent.
Then, if you want to extend the duration of your repair, a water-based water repellent treatment can be applied. Thus, you have peace of mind for at least 10 years, without being concerned about water infiltration, even if your brick is the porous type.
Avoid the "Beef Belly"
If repointing is not done in time, you could wind up with what is known in our jargon as a "beef belly". This means that the bricks are coming loose from their backing, and begin sagging outwards. If this is the case, we must immediately address the situation to prevent a collapse. We must dismantle the affected part and reinstall the bricks or stones, replacing any that are broken or in poor condition.
That's why MF Maçonnerie Inc. is here to help you with a good repointing at the first signs of damage. In addition to repointing, we offer the replacement of spandrels, lintels and angle irons as well as installation of flashing. We also repair stone or brick chimneys.
