How much does it cost to build a 12x16 deck in Moncton NB?

A 12x16 deck in Moncton will cost between $4,800 and $14,400 depending on your material choice, with pressure-treated lumber at the low end and composite decking at the high end. This 192-square-foot deck is one of the most common sizes built in the Moncton area, large enough to comfortably fit a dining table and a small seating area while remaining manageable in terms of both budget and building complexity.

For a pressure-treated lumber deck, which remains the most popular choice in the Greater Moncton area, expect to pay $4,800 to $7,700 installed. This price includes the footings, framing, decking boards, a basic staircase, and standard wood railings. Pressure-treated decking runs $25 to $40 per square foot installed, and the variation in price depends on the complexity of your site, the height of the deck above grade, the number of footings required, and the contractor you choose. A ground-level deck on a flat lot in Riverview will cost less than an elevated deck on a sloping lot in the north end of Moncton simply because of the additional materials and labour involved in building the substructure.

Cedar decking bumps the cost up to roughly $6,700 to $10,600 for the same 12x16 footprint, reflecting the $35 to $55 per square foot installed price range. Cedar offers a beautiful natural appearance and better resistance to rot than untreated lumber, but it still requires regular staining and sealing to maintain its look in Moncton's climate. Many homeowners find the maintenance commitment is similar to pressure-treated wood, which is why cedar's market share has declined somewhat in favour of composite options.

Composite decking for a 12x16 deck in Moncton runs $8,600 to $14,400 installed, based on the $45 to $75 per square foot range. This broad range exists because composite products vary enormously in quality and price. Entry-level composite boards from brands available at local building supply stores cost less than premium capped polymer products like TimberTech or Trex Transcend. The substructure beneath composite decking is still pressure-treated lumber, so you are paying for composite on the surface and stairs while the hidden framing remains wood.

Labour typically accounts for 40 to 60 percent of your total project cost in the Moncton market, with deck builders charging $25 to $45 per hour. A 12x16 deck takes a two-person crew approximately three to five days to complete, depending on site conditions and complexity. The footing work is often the most variable cost factor. Each footing runs $150 to $350, and a 12x16 deck typically requires six to nine footings depending on the span of your beams and joists. In Moncton, footings must extend below the frost line, which is approximately 4 feet deep, and they need to bear on undisturbed soil or compacted granular fill.

Railings add a meaningful amount to the budget and deserve separate consideration. Basic pressure-treated wood railings run $30 to $60 per linear foot, while aluminum railings cost $50 to $100 per linear foot and glass panel systems range from $100 to $200 per linear foot. A 12x16 deck has roughly 40 to 44 linear feet of railing perimeter after subtracting the house wall and stair opening, so your railing choice can add $1,200 to $8,800 to the project. Many Moncton homeowners choose a mid-range aluminum railing system in the $50 to $75 per linear foot range as a good balance between appearance, durability, and cost.
