What is the total material cost breakdown for a 12x16 pressure-treated deck in NB?

For a 12x16 pressure-treated deck (192 sq ft) in New Brunswick, expect total material costs of $1,800-$2,800, with lumber being your biggest expense at $800-$1,200.

Here's the detailed material breakdown for your 192 square foot deck:

Structural Lumber ($800-$1,200)
Your framing will need 2x10 joists at 16" on center, requiring about 12-14 joists at roughly $25-$35 each. Add a double 2x10 beam ($80-$120), 6x6 posts for support ($40-$60 each for 3-4 posts), and a 2x10 ledger board ($60-$80). The rim joists and blocking will add another $150-$200 to your lumber costs.

Decking Boards ($400-$700)
For 192 sq ft of surface area, you'll need approximately 20-22 pieces of 5/4" x 6" pressure-treated decking boards, assuming 16-foot lengths. Quality PT decking runs $18-$32 per board in New Brunswick. Always buy 10% extra for cuts and potential defects.

Footings and Concrete ($200-$400)
In New Brunswick, your footings must extend 1.2 meters deep (1.5m in northern regions like Bathurst). Plan for 4-6 concrete footings using 10" diameter Sonotubes. Each footing requires 1-2 bags of concrete at $6-$8 per bag, plus the Sonotubes at $15-$20 each.

Hardware and Fasteners ($150-$250)
You'll need galvanized joist hangers ($3-$5 each for 12-14 hangers), lag bolts for ledger attachment ($40-$60), galvanized deck screws ($60-$100 for 5 lbs), and post anchors ($15-$25 each). Don't skimp on fasteners in NB's harsh climate - use only galvanized or stainless steel.

Flashing and Moisture Protection ($50-$100)
Ledger flashing is mandatory in New Brunswick's wet climate and costs $30-$50. Add joist tape ($20-$40) to protect the top of your joists from moisture - essential given our 100+ freeze-thaw cycles annually.

Railings (if required) ($300-$600)
If your deck is 24" or higher above grade (NB Building Code requirement), you'll need railings. Basic PT railing components for a 12x16 deck perimeter run $300-$600 in materials, including posts, top/bottom rails, and balusters spaced no more than 4" apart.

Regional Pricing Notes
Lumber prices in Moncton, Saint John, and Fredericton tend to be 10-15% lower than in Miramichi or Bathurst due to better supply access. Always shop multiple suppliers - prices can vary significantly between Home Depot, Kent, and local lumber yards.

Money-Saving Tips
Buy lumber in late fall or winter for spring construction when demand is lower. Consider purchasing directly from sawmills if you're near one - you can save 20-30% on rough lumber that you plane yourself.

Remember, this covers materials only. Professional installation typically adds $25-$40 per square foot in labor costs. Need help finding a qualified deck builder? New Brunswick Decks can match you with local contractors for free estimates on your project.
