Next you’ll need to choose the type of deck boards you’ll use to finish your deck. Pressure-treated wood is a popular choice because it’s long-lasting, affordable and is infused to make it mould and rot resistant. Cedar is more expensive but usually considered to be a more premium looking deck board, it is naturally moisture and rot resistant looks great. Composite decking is an alternative to wood and is extremely durable and great for heavy traffic. Holes for deck screws need to be pre-drilled though, making it a bit more work to install. When choosing deck boards, make sure they’re straight by looking length-wise down the edge and checking for bows, as if the board is bowed too much, you’ll have trouble getting it to fit snugly against the other boards. Also make sure that there is at least one clean side with no blemishes, and use that side up when drilling them in place. You’ll also need decking screws, which have a larger head but are stronger than traditional screws. You can even get screws to match the colour of your wood to help them blend in.
