What is the average cost of deck board replacement in New Brunswick in 2026?

Deck board replacement in New Brunswick typically costs $8-$18 per square foot for materials and labour combined, depending on your choice of decking material and the complexity of your existing deck structure.

For a standard 12x16 foot deck (192 square feet), you're looking at $1,500-$3,500 total for board replacement. Pressure-treated lumber sits at the lower end ($8-$12/sq ft), while composite decking pushes toward the higher range ($14-$18/sq ft). Cedar falls somewhere in the middle at $10-$15 per square foot.

Material costs alone break down roughly as follows: pressure-treated deck boards run $3-$5 per square foot, cedar ranges $4-$7 per square foot, and composite materials cost $6-$12 per square foot. Labour typically adds another $4-$6 per square foot, though this can increase if your existing joists need repair or if access is challenging.

Several factors significantly impact your final cost. If the contractor discovers rotted or damaged joists during board removal, expect additional charges of $15-$25 per linear foot for joist replacement. Stairs, railings, and multi-level decks increase labour complexity. Properties with difficult access or disposal challenges (common in rural New Brunswick) may see higher quotes.

Timing matters for your budget — scheduling replacement during shoulder seasons (May or September) often yields better contractor availability and potentially lower rates than peak summer months. Many New Brunswick contractors book solid through July and August.

Before replacing boards, have your contractor inspect the underlying structure. New Brunswick's freeze-thaw cycles are particularly hard on deck framing, and it's far more cost-effective to address structural issues during board replacement rather than discovering problems later. If your deck is over 15 years old, consider having the ledger board connection inspected — older decks sometimes lack proper flashing or adequate fastening.

Your next step should be getting quotes from at least three contractors in your area. Ask specifically whether their quote includes disposal of old materials (typically $200-$400 extra) and whether they've factored in potential joist repairs. Most contractors will provide a firm quote for board replacement with a separate allowance for any structural work discovered during the project.
