Discover how timely repainting keeps your building structurally sound and avoids costly repairs
Property managers often focus on visible brickwork damage — missing bricks, cracks, or stains. But one of the most overlooked threats to building integrity is deteriorating mortar. These subtle shifts in your building’s joints can go unnoticed until moisture, structural movement, or falling debris make the problem urgent. Understanding the early signs of mortar failure helps prevent expensive repairs and preserve the building’s long-term value.
Why Mortar Joints Matter More Than You Think
Mortar isn’t just filler between bricks — it’s a critical component that binds the structure, seals out moisture, and absorbs expansion and contraction. Over time, Montreal’s freeze-thaw climate, pollution, and vibration from traffic wear down this essential barrier. As mortar begins to crack, shrink, or erode, your building becomes vulnerable to water damage, instability, and costly façade repairs.
Research from the Canadian Concrete Masonry Producers Association shows that weak or aged mortar is one of the leading causes of masonry system failure in urban commercial properties.
Common Signs of Mortar Failure Property Managers Overlook
Some signs of mortar degradation are obvious — such as visible cracks or pieces crumbling onto the ground. But others are more subtle. Color fading, small gaps between bricks, or powdery residue (efflorescence) can all signal underlying issues.
Pay close attention to:
-
Vertical and horizontal cracks in the mortar
-
Separation between brick and mortar (known as debonding)
-
Rounded or recessed joints (indicative of erosion)
-
Moss or vegetation growing in the joints
Timely repointing can stop these issues from spreading and restore both the appearance and structural performance of your building.
How Repointing Restores Structural Integrity
Repointing is the process of removing damaged mortar and replacing it with new, compatible material. While it may seem cosmetic, it has major structural implications. Properly executed repointing restores lateral stability, reduces water absorption, and extends the building’s functional lifespan by decades.
Working with a skilled Brique Maconnerie team ensures your repairs are performed using materials and techniques appropriate to the building’s age and style — particularly important for Montreal’s heritage properties and commercial buildings with aesthetic standards.
When to Repoint: Timing and Frequency
Mortar deterioration doesn’t follow a set schedule. While most mortar lasts 25–30 years, exposure to wind, salt, pollution, and water can speed up decay.
As a property manager, you should:
-
Schedule annual exterior inspections and document mortar condition changes.
-
Request mortar testing or analysis when cracks or erosion appear.
-
Work with contractors who can match historic mortar color and texture for aesthetic consistency.
Proactive repointing reduces the risk of structural compromise and demonstrates responsible asset management — a priority for both investors and tenants.
The Canada Masonry Design Centre (CMDC) offers excellent resources on repointing and preservation methods (canadamasonrydesigncentre.com).
Conclusion
Cracked or recessed mortar might seem like a cosmetic issue, but it’s often the first indicator of deeper structural problems. By spotting these warning signs early and partnering with qualified masonry professionals, property managers can protect their investment, avoid liabilities, and maintain the building’s appearance and function.
