How much does it cost to fill and seal alligator cracking on my asphalt driveway in Orleans?

Alligator cracking — that web of interconnected cracks that looks like reptile skin — is one of the most common asphalt failures Ottawa contractors deal with every spring, and the cost to address it depends on how deep the damage goes.

Cost Ranges for Alligator Crack Repair in Ottawa

For surface-level alligator cracking confined to a small area (under 50 square feet), crack filling and seal coating typically runs $300–$600. If the cracking covers a larger section and the base beneath has softened, contractors in Orleans and eastern Ottawa usually recommend infrared patching or a cut-and-patch repair at $800–$2,500 depending on the area. When alligator cracking spans more than 30–40% of the driveway surface, full resurfacing at $3.50–$6.00 per square foot is usually the more cost-effective path.

Why Alligator Cracking Is So Common in Ottawa

Ottawa's extreme freeze-thaw cycles are the primary culprit. Temperatures can swing from -30°C in January to +5°C during a mid-winter thaw, and that repeated expansion and contraction weakens the asphalt binder over time. Water infiltrates small cracks, freezes and expands, then thaws and settles deeper into the base layer. After a few winters of this — especially on driveways in Orleans, Gloucester, and other areas with high water tables — the subsurface aggregate loses its structural integrity and the surface starts to flex and crack in that telltale pattern.

Repair Methods Ottawa Contractors Use

• Crack filling with hot rubberized sealant works when cracks are isolated and the base is still solid. The material flexes with temperature changes, which is critical for Ottawa's climate range.
• Infrared asphalt patching heats the damaged area to 175°C, allowing contractors to rake out the failed material, add fresh hot mix, and compact it seamlessly. This method bonds the new material to the old, eliminating cold joints that fail in our winters.
• Full-depth patching involves sawcutting the damaged area, excavating the failed base, replacing with fresh Granular A compacted in lifts, and laying new hot mix. This is essential when Leda clay subsoil has allowed moisture to compromise the base.

If the alligator cracking returns within a year of patching, the base layer has likely failed. Continuing to patch over a compromised base is throwing money away. A qualified contractor will probe the area to check base depth and drainage conditions before recommending full reconstruction versus overlay.

Spring Timing Matters

Hot mix asphalt plants in the Ottawa region typically open in late April or early May. Book your assessment in March or early April to get on the spring schedule, as contractors in Orleans and across Ottawa fill up quickly after the snow melts and homeowners see the winter damage.
