Preventive Maintenance
Crack Filling & Joint Sealing in Toronto
If you need crack filling or joint sealing in Toronto, this is the highest-return maintenance you can do. Hot rubberized sealant keeps water out of the base, stopping the freeze-thaw cycle that turns small cracks into potholes.
What Crack Filling Involves
Crack filling in Toronto is about one thing: keeping water out of the base. Every open crack is a doorway for water to reach the base, freeze, expand, and tear the pavement apart. We clean each working crack, then fill it with hot rubberized sealant that flexes with the pavement through temperature swings and stays sealed where cheap cold fillers crack and pull away.
- Cleaning and drying of cracks for proper adhesion
- Removal of vegetation and debris from the crack
- Hot rubberized sealant application
- Joint sealing at cold joints and edges
- Smoothing flush with the surface
Which Cracks to Seal, and When
Seal cracks while they are still narrow lines, ideally before winter. Good candidates are working cracks up to about a half inch, cold joints, and edge cracks. Once cracks widen into alligator patterns, sealing is no longer enough. That signals base failure and needs repair or resurfacing. The best time to crack seal in Toronto is late summer or early fall, so your pavement goes into winter sealed against the freeze-thaw cycle that does the most damage.
Crack Sealing Cost and Payback
Crack sealing is inexpensive relative to what it prevents. Filling a season's worth of cracks costs a small fraction of repairing the potholes and base damage those cracks would cause if left open through winter. It is the clearest example of pay-a-little-now-or-a-lot-later in all of asphalt maintenance. Pricing depends on the linear footage of cracks and site access. We often pair crack sealing with sealcoating for full surface protection in one visit.
The Number One Winter Defence in Toronto
If you do only one maintenance task on your asphalt before a Toronto winter, make it crack sealing. Water in cracks is the single largest cause of pavement damage in our climate. With 40 or more freeze-thaw cycles a season, an open crack fills with water, freezes, widens, and repeats, dozens of times, until the base is compromised and potholes form. Sealing those cracks in the fall cuts off the water path and can add years to a surface for very little cost. It is the highest-leverage thing you can do for your driveway or lot.
Our Process
Identify working cracks
We map cracks worth sealing and flag any that signal deeper base problems instead.
Clean and dry
We clear debris and vegetation and dry the crack so the sealant adheres properly.
Apply hot sealant
We fill with hot rubberized sealant that flexes with the pavement through temperature swings.

Crack Filling & Joint Sealing FAQs
When is the best time to crack seal in Toronto?
Late summer to early fall is ideal, so the pavement enters winter sealed against freeze-thaw. Cracks should be dry and clean for the sealant to adhere, which is easier in warmer, drier weather.
What size cracks can be sealed?
Working cracks up to about a half inch, plus cold joints and edge cracks, are good candidates. Wider alligator cracking signals base failure and needs repair or resurfacing rather than sealing.
How long does crack sealant last?
Quality hot rubberized sealant typically holds for several years because it flexes with the pavement. Cold pourable fillers from a hardware store tend to crack and pull away within a season in our climate.
Should I crack seal and sealcoat together?
Often yes. Crack filling handles the openings that let water into the base, and sealcoating protects the broad surface from salt and UV. Done together, they give complete protection, and we can do both in one visit.
