Cracked or deteriorating concrete doesn't automatically need complete replacement. The right solution depends on what caused the damage and the condition of the underlying slab.

Localized cracks, surface scaling, worn areas, and damaged edges may be candidates for professional repair or resurfacing when the remaining concrete is stable.

More serious warning signs include significant settlement, major movement, widespread deep deterioration, or sections that have become severely uneven. In these situations, simply repairing the visible surface may not address the underlying problem.

Tip: Don't decide based on appearance alone. Have the concrete assessed to determine whether repair, resurfacing, or replacement is appropriate. Addressing deterioration early may provide more repair options and help prevent the affected area from becoming worse.

Keeping walkways, steps, and driveways safe during winter is important, but repeatedly applying large amounts of de-icing salt can be hard on concrete.

Concrete absorbs moisture. De-icing products can increase the number of freeze-thaw cycles the surface experiences, while some salts may also contribute to scaling and surface deterioration over time.

Newer concrete and already damaged surfaces can be particularly vulnerable. Whenever possible, remove snow promptly before it becomes compacted or turns to ice.

Tip: Use de-icing products sparingly and follow the manufacturer's directions. For traction, homeowners can also consider options such as sand where appropriate. Inspect the concrete again in spring for scaling, cracks, or loose areas that may need attention.

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.
