The weather in Toronto is characterized by its significant disparity — from freezing cold winters with lots of snow to hot and humid summers! These fluctuating temperatures can take a toll on both the stability and strength of the brick in homes. Due to different conditions in each of the seasons your bricks can become worn and weathered. So, it’s important to know how weather does a number of things to your home’s exterior to help ensure its structure and keep repair costs down the road at bay. 

Freeze-Thaw Cycles and Brick Deterioration 

With respect to its impact on the brick homes, Toronto weather can be particularly destructive in the case of the freeze-thaw cycle. In the colder months, moisture can get into small cracks or porous parts of the bricks. When temperatures fall below freezing, the moisture expands as it freezes, leading the brick or mortar to crack and crumble. The brick also degrades over time due to freezing and thawing, wear and tear, and other factors, in which repeated freezing and thawing may cause the brick structure to weaken and cause cosmetic damage. This is one of the primary reasons why homeowners look into brick repair Toronto services, especially after a hard winter. 

Rain and Water Penetration 

Brick offers the added benefit of being a fireback material that is resistant to water damage, although rain if allowed to penetrate a wet or broken mortar joint can ultimately cause the brick to weather / break down. In Toronto, spring and fall see a fair amount of rain, and the water is not good here, with homes at an elevated risk of water damage. When water gets behind the brick veneer, it can cause internal problems such as mold and mildew and even structural damage. It can make a space less appealing and if not attended to, can advance to the point that brick work dating back generations requires professional brick repair Toronto. 

Summer Heat and UV Exposure 

The summers in Toronto are no joke when it comes to heat and UV exposure. While exposure to the sun will not necessarily lead to immediate damage, it will speed the bricks' aging process. Reduction of temperature at night causes the air to cool and contract. As time goes on, this back and forth can cause cracking and failing mortar. What’s more, UV rays can dry out the exterior of the bricks, which may result in the natural color being lost and also make them more brittle. These can take years to develop, but they will eventually lead to the necessary brick repair Toronto. 

Wind and Erosion Effects 

Bricks are also often subjected to powerful winds, which, often containing particles like dust and stones, wear down the surface of bricks. Less immediately damaging than moisture, wind erosion eats away at brick facades over time. On open areas or houses situated near excavations where there is construction, particles driven by the wind can lead to accelerated surface erosion that may lead to homeowners to contemplate premature brick repair Toronto. 

Fluctuating Weather and Seasonal Stress 

What makes Toronto’s weather especially trying is its unpredictability. Robust changes in temperature or extreme dryness followed by wetness produce severe stresses in base materials. Those shifts can wear out the chimney, too, especially in older homes with the original masonry. Then as many times, as the seasons change, thes breaks have been inevitable and are damages, and small breaks, displaced mortar and general wear and tear is inevitable and require expert attention to them by contracting the services for brick repair Toronto. 

Protecting Your Home with Timely Maintenance 

However, inevitable some damage to your home may be as a result of weather conditions, routine maintenance can help to prevent potential issues in the future. Frequent check-ups of the brickwork can help to catch any early symptoms of decay. Seeing small cracks or crumbling mortar or discoloured areas can allow homeowners to make preventive maintenance efforts before there is worse damage.
