What is the average price per square foot for driveway resurfacing in Kanata?

Driveway resurfacing in Kanata typically costs $3 to $7 per square foot for asphalt overlay, with most homeowners paying around $4 to $5 per square foot for quality work. For an average Kanata driveway (50-60 square metres), expect to budget $2,500 to $5,500 for professional resurfacing.

Resurfacing involves applying a new 40-50mm layer of hot-mix asphalt over your existing driveway surface — it's significantly less expensive than full replacement because it doesn't require excavation or new base work. However, resurfacing is only viable if your existing driveway has a stable base and surface damage limited to the top layer. Driveways with base failure, extensive cracking, or drainage issues need full replacement, not resurfacing.

Kanata's housing stock affects resurfacing options significantly. Many 1980s-1990s Kanata subdivisions have asphalt driveways that are now 25-35 years old and excellent candidates for resurfacing if the base remains stable. However, some areas of Kanata sit on Ottawa River valley clay soils that can cause base movement — if your driveway shows signs of heaving, settling, or alligator cracking, the base has likely failed and resurfacing won't solve the underlying problem.

Ottawa's extreme climate makes timing critical for resurfacing projects. The work must be completed when ambient temperatures are consistently above 10°C and rising, typically late May through September. Hot-mix asphalt cools rapidly in cold conditions, preventing proper compaction. Many Kanata contractors book resurfacing work for late summer (August-September) when demand is slightly lower than peak spring season.

Before resurfacing, your contractor should fill any cracks wider than 5mm with hot-pour rubberized crack filler and address any drainage issues that caused the original surface deterioration. The existing surface must be cleaned of all loose material, vegetation, and debris. A quality resurfacing job in Kanata includes proper edge work to feather the new asphalt into existing grades and ensure water drainage away from your foundation.

Resurfacing adds 15-20 years to your driveway's lifespan when done properly, but only if the underlying base is sound. If you're seeing potholes, extensive cracking, or areas where the driveway has settled or heaved, full replacement with proper base preparation is the better long-term investment. A resurfaced driveway should be sealed 12-18 months after installation, then every 2-3 years to protect against Ottawa's freeze-thaw cycles and road salt exposure.
