Choosing between concrete and asphalt is one of the most common dilemmas for Ottawa homeowners replacing a driveway. Both are excellent choices, but they differ significantly in upfront cost, maintenance requirements, lifespan, and performance in Ottawa's extreme climate. The quick answer: Asphalt costs less upfront and is easier to repair, but requires ongoing maintenance (seal coating) and has a shorter lifespan. Concrete costs more upfront but requires less maintenance and lasts significantl...
Asphalt driveway: $5–$10 per square foot installed. A standard double-car driveway (600 sq ft) costs $3,000–$6,000. Annual seal coating ($200–$500 every 2–3 years) and crack filling ($100–$300 as needed) bring the 25-year total cost to approximately $5,000–$10,000. Concrete driveway: $10–$18 per square foot installed. A standard double-car driveway costs $6,000–$10,800. Minimal maintenance (joint sealing every 5 years, $100–$200) brings the 30-year total cost to approximately $6,500–$12,000. E...
Freeze-thaw resistance: Both materials handle freeze-thaw cycles, but in different ways. Asphalt is flexible — it bends and flexes with ground movement without cracking (to a point). Concrete is rigid and will crack if the ground shifts significantly. However, properly installed concrete with adequate control joints manages freeze-thaw well. Salt and de-icer performance: Asphalt handles road salt well with no surface damage. Concrete can be damaged by salt — especially in the first winter befor...
Choose asphalt if: You want the lowest upfront cost, don't mind maintenance every 2–3 years, want easy snowplow compatibility, like the traditional dark appearance, or plan to move within 10–15 years. Asphalt is the practical, affordable choice that 70% of Ottawa homeowners make. Choose concrete if: You want a premium appearance, prefer minimal maintenance, plan to stay in your home 15+ years, want design options (stamped, exposed aggregate, coloured), or value long-term cost efficiency. Concre...
Asphalt is cheaper upfront ($3,000–$6,000 vs $6,000–$10,800 for a standard driveway). Over 30 years, total costs are similar when maintenance and replacement are factored in.
Concrete lasts 30+ years with minimal maintenance. Asphalt lasts 15–25 years with regular seal coating. Concrete wins on longevity; asphalt wins on repairability.
Technically possible but not recommended. The asphalt underneath continues to deteriorate, causing the concrete above to crack. Best practice is to remove the old asphalt, prepare a proper base, and install fresh concrete.
Asphalt handles snowplowing better and melts snow faster due to heat absorption. Concrete is more resistant to long-term wear but can be damaged by salt in the first year. Both perform well in Ottawa winters when properly installed.
