Ice Management and De-Icing
Ontario winters are characterized by fluctuating temperatures — warm spells in January, cold snaps in March, and everything in between. This freeze-thaw cycle is one of the most damaging phenomena for both your property and your maintenance budget.
How freeze-thaw works: water infiltrates cracks in concrete, asphalt, and masonry. When that water freezes, it expands by approximately 9%, exerting tremendous pressure. Repeated cycles accelerate damage dramatically — a hairline crack in fall becomes a pothole by spring.
Best Practices for Ontario Winters
Property protection strategies during freeze-thaw periods: seal cracks in pavement and concrete in early fall before water infiltration begins. Apply penetrating concrete sealer to exposed concrete surfaces (driveways, steps, sidewalks) every 3-5 years.
Ice management during thaw-refreeze events: when daytime temperatures rise above 0°C and refreezing is expected overnight, pre-treating high-risk surfaces in the late afternoon significantly reduces overnight ice formation. Monitor forecasts during transition weather.
Professional Snow and Ice Control
Eavestrough management: freeze-thaw cycles create ice dam conditions and eavestrough stress. Ensure gutters are clear before temperature swings to allow meltwater to drain properly rather than pooling and freezing.
Concrete damage from salt: sodium chloride ice melt accelerates freeze-thaw damage to concrete by increasing the number of freeze-thaw cycles the surface experiences. Use calcium chloride or magnesium chloride on concrete surfaces, or use sand for traction without the chemical salt cycle effect.
Pavement inspection in spring: after the final thaw, inspect your driveway and pavement for new cracks and damage. Addressing small cracks in spring prevents larger failures the following winter. D&D Snow Services can advise on pavement condition observations during our service visits.
