How much does it cost to replace a concrete driveway in Saint John versus repaving with asphalt?

Replacing a concrete driveway in Saint John typically costs $8-15 per square foot ($4,000-8,000 for a standard two-car driveway), while asphalt repaving runs $3-7 per square foot ($1,500-4,000 for the same driveway). However, the long-term value equation in New Brunswick's harsh Maritime climate strongly favors concrete despite the higher upfront cost.

Concrete Driveway Replacement Costs in Saint John:
A typical 400-600 square foot two-car driveway ranges from $4,000-8,000 for standard broom-finished concrete, or $5,000-12,000 for stamped or decorative concrete. This includes complete removal of the existing driveway ($2-5 per square foot), excavation, 6-inch compacted gravel base, air-entrained concrete (essential in NB's freeze-thaw conditions), reinforcement with wire mesh or rebar, proper finishing, and control joints. Saint John contractors generally price at the lower end of the provincial range due to good competition and proximity to ready-mix plants.

Asphalt Repaving Costs:
Asphalt overlay (repaving over existing asphalt in good condition) costs $3-5 per square foot, while complete asphalt replacement runs $5-7 per square foot. A standard driveway repave typically costs $1,500-4,000. However, this assumes the existing base is sound — if the gravel base needs rebuilding, costs approach concrete pricing.

Why Concrete Makes Sense in Saint John's Climate:
Saint John experiences over 150 freeze-thaw cycles annually, plus salt air from the Bay of Fundy that accelerates pavement deterioration. A properly installed air-entrained concrete driveway lasts 25-40 years in these conditions, while asphalt typically requires resurfacing every 8-12 years and complete replacement every 15-20 years. Factor in the cost of seal coating asphalt every 2-3 years ($0.50-1.00 per square foot), and concrete becomes cost-competitive over its lifespan.

Additional Considerations:
Concrete handles Saint John's winter conditions better — it doesn't soften in summer heat, resists oil stains more effectively, and won't develop the ruts and depressions common with asphalt under heavy vehicles. However, concrete requires a penetrating sealer every 2-3 years ($1-2 per square foot) to protect against salt damage from winter road treatments.

Timing and Seasonal Factors:
Both materials work best installed between May and October in New Brunswick. Asphalt plants typically close earlier in fall (late October) than concrete operations, potentially limiting late-season options.
