Montreal, Verdun and Laval are home to some of the most beautiful historic brick buildings, but over time, weather conditions, aging mortar, and general wear can weaken their structural integrity. Brick repointing and restoration are essential for maintaining these properties, ensuring they remain strong and visually appealing for generations to come.

In this guide, we’ll explore the importance of repointing, the step-by-step process, and why professional restoration is key to protecting your home’s masonry.

What is Brick Repointing and Restoration?

Brick repointing involves removing deteriorated mortar from joints and replacing it with fresh mortar to reinforce the structure and prevent further damage. Over time, mortar joints can crack, erode, or become loose due to exposure to the elements. Without proper maintenance, this deterioration can lead to moisture infiltration, structural instability, and unsightly brickwork.

Masonry restoration goes beyond repointing, addressing issues such as:

• Brick replacement for damaged or missing bricks
• Cleaning and sealing to remove stains and protect against moisture
• Structural reinforcement to prevent long-term deterioration

For homeowners in Westmount and across Montreal, these restoration techniques ensure that historic properties maintain their charm while staying safe and secure.

Signs Your Brickwork Needs Repointing

Knowing when to invest in repointing is key to avoiding costly repairs down the line. Here are some common signs that your masonry needs attention:

1. Crumbling or Missing Mortar

If you notice gaps or loose mortar between your bricks, this is a clear indication that repointing is needed. Mortar is essential for keeping bricks in place and preventing water infiltration. When it weakens, your walls lose stability.

Tip: Take a small tool and scrape along the mortar joints—if it crumbles easily, it’s time for repointing.

2. Water Infiltration and Efflorescence

Efflorescence—white, powdery salt deposits on brick surfaces—indicates moisture penetration. When water seeps into mortar joints, it can lead to structural damage, mold growth, and further deterioration.

Tip: Look for damp patches on interior walls near brick surfaces—this could signal hidden moisture problems.

3. Cracked or Spalling Bricks

If bricks are flaking or breaking apart, the issue often stems from failing mortar. Spalling occurs when moisture trapped in the bricks expands and contracts due to temperature changes, causing the surface to chip away.

Tip: Inspect the lower sections of your home’s exterior, as they are more prone to moisture damage.

The Brick Repointing Process: Step-by-Step

Repointing is a delicate process that requires precision and expertise. Here’s how professionals at JV Deco ensure long-lasting results:

1. Inspection and Mortar Analysis

A thorough assessment determines the extent of damage and ensures the new mortar matches the original composition for durability and aesthetics.

2. Removing Old Mortar

Using specialized tools, the old, deteriorated mortar is carefully removed without damaging the surrounding bricks. This step prevents unnecessary weakening of the structure.

3. Preparing and Applying New Mortar

A fresh batch of mortar, matched in color and texture, is applied between the bricks. Proper application is key to ensuring a secure bond and long-term protection.

4. Tooling and Finishing

The joints are shaped to match the original design, ensuring a seamless look. This step also enhances the strength and weather resistance of the masonry.

5. Curing and Sealing

The newly applied mortar is allowed to cure properly, and, if necessary, a protective sealant is applied to prevent future moisture damage.
