As a homeowner in southern Ontario, you’re no stranger to the region’s unique and often challenging climate. From frigid winters to humid summers, our weather can take a toll on our homes, particularly on brick structures like garages. In this comprehensive guide, we’ll explore how Ontario’s climate impacts brick durability and what you can do to protect your masonry investments.
The Impact of Freeze-Thaw Cycles on Brick
One of the most significant challenges facing brick structures in Ontario is the constant freeze-thaw cycle that occurs during our winters and early spring.
Understanding the Freeze-Thaw Process
When water seeps into the porous surface of bricks and mortar, it can freeze as temperatures drop. This freezing causes the water to expand, creating pressure within the brick. As temperatures rise again, the ice melts, but the cycle repeats with each temperature fluctuation. Over time, this process can lead to:
- Cracking and spalling of brick surfaces
- Deterioration of mortar joints
- Structural weakening of the entire masonry wall
Why Garages Are Particularly Vulnerable
Garages often face increased risk from freeze-thaw cycles due to several factors:
- Exposure to road salt and de-icing chemicals brought in by vehicles
- Lack of climate control, leading to more extreme temperature fluctuations
- Potential for poor ventilation, trapping moisture inside
Effects of Humidity and Moisture on Masonry
Ontario’s humid summers present another set of challenges for brick structures, especially in enclosed spaces like garages.
The Role of Humidity in Brick Deterioration
High humidity levels can contribute to several issues:
- Efflorescence: The white, powdery substance that forms on brick surfaces due to salt migration
- Mold and mildew growth, particularly in shaded or poorly ventilated areas
- Accelerated weathering of mortar joints
Moisture Intrusion in Garage Brickwork
Garages are often more susceptible to moisture-related problems due to:
- Ground moisture wicking up through foundation walls
- Improper drainage around the structure
- Condensation from vehicles and temperature differences
Seasonal Maintenance Tips for Garage Brickwork
To combat the effects of Ontario’s climate on your garage’s brickwork, follow these seasonal maintenance tips:
Spring Maintenance
- Inspect brickwork for winter damage, looking for cracks, spalling, or loose mortar.
- Clean gutters and downspouts to ensure proper water drainage away from the structure.
- Apply a breathable water repellent to protect against spring rains.
Summer Maintenance
- Check for and address any signs of efflorescence or mold growth.
- Ensure proper ventilation to reduce humidity levels inside the garage.
- Trim vegetation away from brick walls to prevent moisture retention.
Fall Maintenance
- Repoint any deteriorated mortar joints before winter sets in.
- Seal any cracks or gaps in the brickwork to prevent water infiltration.
- Consider applying a penetrating sealer to protect against freeze-thaw cycles.
Winter Maintenance
- Remove snow and ice from around the foundation to prevent moisture buildup.
- Avoid using de-icing salts near brick surfaces when possible.
- Monitor indoor humidity levels and use a dehumidifier if necessary.
Climate-Specific Masonry Solutions for Ontario Homes
To address the unique challenges posed by Ontario’s climate, consider implementing these masonry solutions:
Proper Brick Selection
Choose bricks with appropriate frost resistance ratings for our climate. Look for:
- SW (Severe Weathering) grade bricks for maximum durability
- Low absorption rates to minimize water penetration
- Proper sizing and installation to allow for thermal expansion
Advanced Mortar Formulations
Use mortar mixes designed to withstand Ontario’s freeze-thaw cycles:
- Type N mortar for above-grade applications
- Type S mortar for below-grade and severe exposure areas
- Consider adding air-entraining agents to improve freeze-thaw resistance
Proper Drainage and Waterproofing
Implement effective water management strategies:
- Install proper flashing and weep holes in brick veneer walls
- Ensure adequate grading and drainage around the garage foundation
- Apply waterproofing membranes to below-grade masonry walls
Long-Term Brick Preservation Strategies
To ensure the longevity of your garage’s brickwork, consider these long-term preservation strategies:
Regular Professional Inspections
Schedule annual inspections with a masonry expert to catch and address issues early. These inspections should include:
- Thorough examination of all brick surfaces and mortar joints
- Assessment of structural integrity and potential moisture issues
- Recommendations for necessary repairs or preventative measures
Timely Repairs and Repointing
Address any damage promptly to prevent further deterioration:
- Repair or replace damaged bricks as soon as they’re identified
- Repoint deteriorated mortar joints using appropriate materials and techniques
- Consider partial rebuilding of severely damaged sections if necessary
Climate Control and Ventilation
Implement measures to regulate the environment inside and around your garage:
- Install proper ventilation systems to reduce humidity levels
- Consider adding insulation to minimize temperature fluctuations
- Use dehumidifiers during humid summer months
Protective Coatings and Sealants
Apply appropriate protective products to enhance brick durability:
- Use breathable water repellents to reduce moisture absorption
- Consider elastomeric coatings for severely weathered surfaces
- Reapply sealants and coatings as recommended by manufacturers

\n\n\nHow does Ontario’s climate affect brick structures?
Ontario’s climate, characterized by freeze-thaw cycles in winter and high humidity in summer, can lead to cracking, spalling, and deterioration of brick surfaces and mortar joints.
What problems do freeze-thaw cycles cause for garages?
Freeze-thaw cycles can cause significant damage to garages by creating pressure that leads to cracking, spalling of brick surfaces, and deterioration of mortar joints, which may compromise structural integrity.
Why are garages especially vulnerable to moisture issues?
Garages are more susceptible to moisture problems due to ground moisture wicking through foundation walls, improper drainage, and condensation from vehicles combined with lack of ventilation.
What seasonal maintenance can help protect garage brickwork?
Recommended maintenance includes inspecting for damage in spring, checking for efflorescence and mold in summer, repointing mortar in fall, and removing snow and ice in winter.
What type of bricks should be used in Ontario’s climate?
Homeowners should choose SW (Severe Weathering) grade bricks with low absorption rates to minimize water penetration and allow for thermal expansion.
What kind of mortar is best for Ontario homes?
Type N mortar is suitable for above-grade applications, while Type S mortar is recommended for below-grade and severe exposure areas, including air-entraining agents for freeze-thaw resistance.
