Small cracks are common in concrete and don't always mean the entire surface needs to be replaced. However, homeowners should keep an eye on cracks that become wider, longer, uneven, or repeatedly allow water to enter.
Toronto's freeze-thaw cycles can make a minor crack worse. Water enters the opening, freezes, expands, and can gradually contribute to additional deterioration.
Watch for warning signs such as crumbling edges, sections becoming uneven, recurring cracks after previous repairs, or water collecting around the damaged area. These may indicate that the problem extends beyond a simple surface crack.
Tip: Take a photo of the crack and check it periodically. If it noticeably changes or surrounding concrete begins deteriorating, have the area professionally assessed before the damage spreads.
