What is the typical cost per linear foot for a poured concrete curb and gutter on a residential driveway in New Brunswick?

Poured concrete curb and gutter for residential driveways in New Brunswick typically costs $15-$30 per linear foot installed, depending on the size, complexity, and whether it's integrated with new driveway construction or added to existing pavement.

For a standard residential curb and gutter (6-8 inches high, 12-18 inches wide at the base), expect to pay $18-$25 per linear foot for most NB installations. This includes excavation, forming, concrete placement, and finishing. Decorative or larger profiles can push costs to $25-$30 per linear foot, while simple landscape curbing (4-6 inches high, primarily for aesthetics) runs $12-$18 per linear foot.

The complexity significantly affects pricing. Straight runs are most economical, while curved sections, radius corners, and integration with existing drainage add 20-40% to the base cost. If the curb and gutter connects to municipal storm drainage or requires catch basins, additional permits and inspection fees apply. Many NB municipalities require a driveway approach permit when modifying drainage patterns near the street connection.

New Brunswick's freeze-thaw cycles demand proper specifications for curb and gutter longevity. The concrete must be air-entrained (4-7% air content) and typically uses a 32 MPa (4,500 PSI) mix for durability against road salt and winter conditions. Proper reinforcement with #10M rebar is essential, especially where the curb transitions to meet existing pavement or drainage structures. Without air entrainment and adequate strength, NB's 150+ annual freeze-thaw cycles will cause spalling and deterioration within 5-7 years.

Timing affects both cost and quality. The optimal installation window is May through October when ground conditions are stable and concrete curing isn't compromised by freezing temperatures. Spring installations (May-June) often cost 10-15% more due to high demand as contractors catch up on winter-delayed projects. Late fall work requires cold weather protection measures that can add $3-$8 per linear foot.

For a typical residential driveway requiring 40-60 linear feet of curb and gutter (along one or both sides), budget $800-$1,500 for basic installation. Decorative stamped or colored curbing for upscale driveways can reach $1,200-$2,000 for the same length.

When to hire a professional: Curb and gutter work requires precise forming, proper drainage slopes (typically 1-2% grade), and integration with existing drainage systems. The concrete must be placed and finished quickly before it sets, and mistakes are highly visible and permanent. DIY is not recommended for this type of work — the specialized forming, drainage calculations, and finishing techniques require professional experience.
