How much does a ground-level 12x12 floating deck cost in Riverview NB?

A 12x12 floating deck in Riverview typically costs $3,600-$5,800 for pressure-treated lumber or $6,500-$10,800 for composite decking, depending on materials and complexity.

For your 144 square foot floating deck in Riverview, you're looking at several cost factors. Pressure-treated lumber remains the most popular choice at $25-40 per square foot installed, giving you that $3,600-$5,800 range. This includes the deck frame, boards, basic stairs if needed, and professional installation. Composite decking like Trex or TimberTech runs $45-75 per square foot, putting your project in the $6,500-$10,800 range, but eliminates the need for annual staining that's crucial in New Brunswick's harsh freeze-thaw climate.

Since you're in Riverview (greater Moncton area), you'll need to account for frost depth requirements of 1.2 metres. Even though floating decks aren't attached to your house, any footings or deck blocks supporting the structure must extend below this frost line to prevent heaving during our 100+ annual freeze-thaw cycles. Many contractors use concrete deck blocks on properly excavated and compacted gravel bases, or pour concrete footings for more permanent installations.

Material considerations for Riverview's climate are important. If choosing pressure-treated lumber, plan for staining every 2-3 years due to our Maritime humidity and UV exposure. Let the lumber dry 3-6 months before first staining, and only stain between mid-May and September when temperatures stay consistently above 10°C. Composite decking eliminates this maintenance cycle entirely, making it increasingly popular despite the higher upfront cost.

Additional costs to budget for include a building permit if your deck will be more than 24 inches above grade (around $150-250 in Riverview), basic railings if required ($30-60 per linear foot for wood), and site preparation if your yard needs leveling. Most contractors can complete a 12x12 floating deck in 2-3 days during the May-October building season.

Timing matters significantly in New Brunswick. Book your contractor by March or April for summer installation, as the best deck builders fill up quickly. The optimal construction window runs May through October when ground conditions allow proper footing work and materials cure correctly.
