How much does it cost to replace a driveway in Saint John NB?

Driveway replacement in Saint John typically costs $8-$15 per square foot for asphalt and $12-$25 per square foot for concrete, meaning a standard 600 square foot driveway runs $4,800-$9,000 for asphalt or $7,200-$15,000 for concrete.

The total cost depends heavily on your driveway size, material choice, excavation requirements, and drainage considerations. Most Saint John driveways range from 400-800 square feet, though longer rural driveways can exceed 1,000 square feet. Asphalt remains the most popular choice in New Brunswick due to its lower upfront cost and ability to handle freeze-thaw cycles better than concrete in our Maritime climate.

Excavation and base preparation represent a significant portion of the total cost — typically $3-$6 per square foot depending on soil conditions and existing driveway removal. Saint John's clay-heavy soils often require additional base material and proper drainage to prevent frost heaving. Many properties in the Saint John area also need grading improvements to direct water away from the foundation, which can add $1,000-$3,000 to the project.

Material costs break down as follows: Hot-mix asphalt runs $5-$8 per square foot installed over a proper base. Concrete costs $8-$15 per square foot for standard 4-inch thickness, with decorative finishes (stamped, coloured, or exposed aggregate) adding $3-$8 per square foot. Gravel driveways cost $2-$5 per square foot but require annual maintenance and aren't ideal for Saint John's steep terrain and heavy rainfall.

New Brunswick's freeze-thaw cycles and spring snowmelt make proper installation critical for driveway longevity. The base must extend below the 4-foot frost line, and proper drainage prevents ice buildup that cracks both asphalt and concrete. Saint John's proximity to the Bay of Fundy means persistent moisture, so drainage planning is especially important. A poorly installed driveway will crack and heave within 2-3 years, while a properly installed one lasts 15-20 years for asphalt or 25-30 years for concrete.

Timing matters significantly for driveway replacement in Saint John. Asphalt installation requires temperatures above 10 degrees Celsius for proper compaction, typically May through October. Concrete can be poured in cooler weather but needs protection from freezing during the 28-day curing period. Spring installation allows the driveway to settle through one freeze-thaw cycle before the next winter.

Additional costs to consider: Permits may be required if the driveway connects to a city street — check with Saint John's planning department. Culvert installation or replacement for drainage costs $500-$2,000. Removing old concrete adds $2-$4 per square foot to disposal costs. If your property has steep grades common in Saint John, additional excavation and retaining wall work can add $2,000-$8,000.
