Where is the cheapest place to buy deck lumber in the Moncton NB area?

Finding the best prices on deck lumber in the Moncton area comes down to a few key suppliers, and shopping around between them can save you meaningful money on a full deck project.

The main options in and around Moncton are Home Depot (on Trinity Drive), Kent Building Supplies (multiple locations including Main Street and the Dieppe location), and Rona. For most homeowners, Kent and Home Depot are the two heavyweights worth comparing first. Kent is a Maritime-based chain and tends to be competitive on lumber pricing, and their staff are generally familiar with local building conditions. Home Depot carries a wide selection and frequently runs promotional pricing on pressure-treated lumber, especially heading into spring.

For potentially better pricing than the big box stores, it's worth checking local lumber yards and building supply independents. Suppliers like Moncton Wholesalers or regional building supply dealers sometimes offer better per-board-foot pricing, especially if you're buying in volume for a full deck project. They may not have the same walk-in retail experience, but if you know your lumber list, calling ahead with a full material list and asking for a quote can result in noticeably lower costs.

A few practical tips for getting the best price:

Bring a complete cut list or material list — suppliers will sometimes offer a small discount on larger orders when you're buying everything at once. Pricing on pressure-treated lumber fluctuates with lumber markets, so what was cheapest last month may not be cheapest today. It's worth calling Kent, Home Depot, and at least one local yard with your list and comparing quotes directly.

Also keep in mind that not all pressure-treated lumber is equal. For ground-contact posts and anything near soil, you need UC4A rated lumber — make sure you're comparing apples to apples when looking at price per board. Cheaper boards rated for above-ground use only won't hold up if used in the wrong application in NB's wet climate.

One thing worth knowing: if you're having a contractor build your deck, they often have trade accounts with suppliers and access to pricing that isn't available to the general public. If you're hiring out the build, it's usually better to let the contractor supply the materials — their cost may actually be lower than what you'd pay retail, even after markup.

If you're still in the planning stage and want to get a sense of total project cost, New Brunswick Decks can match you with local Moncton-area deck builders for free — a good contractor will give you a complete quote including materials so you can see the full picture before deciding how to proceed.
