How much does a 10x10 pressure-treated deck cost to build in Moncton NB?

A 10x10 pressure-treated deck in Moncton typically costs $2,500-$4,000 fully installed, depending on height, railing requirements, and specific site conditions.

For a basic 100 square foot pressure-treated deck in the Moncton area, you're looking at $25-40 per square foot installed. This price range accounts for several factors that affect the final cost. A simple ground-level deck without railings will fall toward the lower end, while an elevated deck requiring railings, stairs, and deeper footings will push toward the higher range.

Material costs make up about 40% of the total project. The pressure-treated lumber itself (joists, decking boards, posts, beams) runs roughly $800-1,200 for a 10x10 deck. You'll also need concrete for footings, galvanized fasteners, joist hangers, and flashing if attaching to your house. In Moncton's freeze-thaw climate, proper footings extending 1.2 metres below ground are non-negotiable — shallow footings will heave and damage your deck within the first winter.

Labor and complexity drive the remaining costs. If your deck is more than 24 inches off the ground, you'll need railings that meet New Brunswick Building Code requirements, adding $30-60 per linear foot. Stairs add another $300-800 depending on the number of steps. Site access, soil conditions, and whether you're attaching to the house versus building freestanding all impact the final price.

Timing matters significantly in New Brunswick's climate. Deck construction season runs May through October when the ground is workable and concrete can cure properly. Booking your contractor by March or April ensures better pricing and availability during peak summer months. Many Moncton deck builders offer slight discounts for early spring bookings before their busy season hits.

Permit requirements in Moncton add $150-250 to your project cost if your deck is attached to the house or elevated more than 24 inches. The permit process typically takes 2-3 weeks, so factor this into your timeline. Even if a permit isn't required, proper construction practices remain essential — Moncton's maritime humidity and freeze-thaw cycles are unforgiving to poorly built decks.

Keep in mind that pressure-treated decks require ongoing maintenance in New Brunswick's climate. Plan to power wash and re-stain every 2-3 years at a cost of $300-600 for a deck this size. However, many homeowners find this maintenance worthwhile given the significantly lower upfront investment compared to composite alternatives.
