Assessing Winter Damage on Brick Masonry in Toronto

Winter in Toronto can be brutal on brick masonry, causing damage that can compromise the structure and appearance of your building. Here’s how to identify and evaluate the damage:


Identifying Common Types of Damage

Winter weather can cause several types of damage to brick masonry:

  • Cracking: Freeze-thaw cycles can cause cracks in brick or mortar joints.
  • Erosion: Snow and ice can wear away at bricks and mortar over time.
  • Salt efflorescence: De-icing salts can seep into brickwork, causing unsightly white deposits and weakening the structure.
  • Mortar joint deterioration: Prolonged exposure to moisture can cause mortar joints to deteriorate, making them more susceptible to cracking or crumbling.


Evaluating Severity & Extent of Damage

To assess the damage, consider these factors:

  1. Distribution: Are the damages localized or widespread? Widespread damage may indicate more severe underlying issues.
  2. Depth: How deep are the cracks or erosion? More severe damage can compromise the structure, while superficial damage is primarily an aesthetic concern.
  3. Mortar joint condition: Examine mortar joints for signs of deterioration. Loose, crumbling, or cracked joints should be addressed promptly to prevent further damage.

If unsure about assessing the damage, consider consulting with a professional like Bowman Masonry (source). They can provide expert guidance on identifying problems and recommending appropriate repair strategies.

Preventing Further Deterioration of Brick Masonry

To safeguard your residence’s or commercial building’s structural integrity, you should guard its brickwork against harsh weather conditions.


Maintain Proper Drainage

Ensure the water flows away from your building by repairing gutters and downspouts well. Also, ensure your landscaping slopes away from the structure to prevent moisture buildup.


Seal Cracks and Gaps

Regularly inspect your brickwork for cracks and gaps that can let water in and cause damage. If you find any issues, repair mortar joints, seal gaps with caulking, or consult a professional like Bowman Masonry for expert advice.


Use Appropriate Cleaning Techniques

Clean your bricks gently using low-pressure methods and mild detergents designed for masonry surfaces. Avoid high-pressure power washing, which can erode mortar joints over time.


List of Recommended Cleaners:


Apply Protective Sealants and Coatings

Consider applying a breathable protective sealant or coating to repel water, reduce efflorescence, and minimize freeze-thaw damage.

Repairing Damaged Brick Masonry

Winter weather in Toronto can wreak havoc on brick masonry but fear not. You can return your structure’s outside to its past splendour with the suitable approach and supplies. Let’s discuss the best methods for repairing damaged brick masonry caused by Toronto’s harsh winter climate.


Identifying the Type of Damage

The first step in repairing damaged brick masonry is identifying the type of damage. Common types include spalling (flaking or chipping), cracking, efflorescence (white salt deposits), and mortar deterioration. Once the damage has been identified, you can determine the most appropriate repair method.


Tuckpointing: A Solution for Mortar Deterioration

Mortar deterioration occurs when water infiltrates the mortar joints between bricks, causing them to weaken over time. Tuckpointing, also known as repointing, involves removing deteriorated mortar from affected areas and replacing it with new mortar that matches the colour and texture of the original.


Steps for Tuckpointing:

  1. Remove old mortar carefully using specialized tools like a grinder or chisel without damaging surrounding bricks.
  2. Thoroughly clean out debris from joints before applying new mortar.
  3. Mix fresh matching-colour mortar according to manufacturer instructions, ensuring proper consistency.
  4. Apply new mortar into cleaned-out joints using a trowel, maintaining even depth throughout the process until filled and compacted correctly.
  5. Finish the surface of new mortar joints to match existing ones and allow it to cure as per the manufacturer’s recommendations.

Brick Replacement: Addressing Spalling and Cracking

In cases where bricks are severely damaged, such as spalling or cracking, brick replacement may be necessary. This process involves carefully removing damaged bricks and replacing them with new ones that closely match in colour, size, and texture. Hiring a professional mason like Bowman Masonry for this task is essential since improper removal or installation can lead to further damage.


Tips for Brick Replacement:

  • Select matching bricks by considering colour, size, texture, and compressive strength.
  • Carefully remove damaged bricks without affecting the surrounding structure using appropriate tools and techniques under expert guidance.
  • Clean out debris from the cavity before installing new brick, ensuring proper fitment within the available space.

Key Takeaway: 

Toronto’s harsh winter climate can cause damage to brick masonry, but it can be repaired with the right approach and materials. Identifying the type of damage is crucial before determining the best repair method, such as tuckpointing for mortar deterioration or brick replacement for severe spalling or cracking.

Protecting Your Brick Masonry from Toronto’s Harsh Winter Weather

Don’t let the cold weather get the best of your building. Here are some preventive measures to maintain the integrity of your brickwork:

Proper Drainage System

Water infiltration can cause significant damage to your brick masonry. Ensure that your gutters and downspouts function correctly and direct water away from your building’s foundation. Consider installing French drains to improve drainage.
