If you’re installing decking boards, it’s important to do it right so you end up with a perfect finish. In this guide, we’ll teach you how to straighten crooked boards, make crisp cuts on the board ends, and avoid common problems like hammer marks and unsightly splits.
We’ll also show you how to properly space your deck boards for a flawless look.
Let’s get started!

1. Plan the layout of your decking boards before installation
One of the most important things to do before installing your decking boards is to plan out the layout. This will help you avoid problems like uneven gaps, raised screw heads, and cracked or split boards.
To plan the layout, start by measuring your deck’s area and sketching out a basic design. Keep in mind that the wider the gaps between your boards, the more water will be able to seep through, so try to avoid spacing them too far apart. Also, make sure to leave enough room for stairs and railings if necessary.
Once you have a basic design sketched out, mark the locations of the joists on the ground using stakes and string. This will help you when it comes the time to install the boards.
Finally, take into account the direction of the sun and plan your deck so that it will be in the shade during peak hours. This will help keep you and your guests cool on hot days.

2. Make sure the ground is level and clear of debris before starting
Before installing your deck boards, it’s important to make sure the ground is level and clear of debris. Uneven ground can cause your deck framing to warp or tilt, and debris can prevent the screws from properly gripping the board.
Use a shovel or rake to remove any bumps or hills to level the ground. If necessary, use a level to make sure the ground is flat. Once the ground is level, use a broom or leaf blower to clean it off and remove any remaining debris.
If you’re installing the deck over concrete, make sure the surface is smooth and free of cracks. If there are any bumps or ridges, use a hammer and chisel to remove them before installing the boards.
3. Install your decking boards perpendicular to the joists
Decking boards should be installed perpendicular to the joists for maximum support. This will also help prevent the boards from warping or splitting.
To install your decking boards, start by installing the first board at one end of the deck. Use a level to make sure it’s straight, and then secure it in place with screws. Once the first board is in place, measure and mark the locations of the other boards. Then, installing them one at a time using the same method.

4. Stagger the joints of your decking boards
When installing decking boards, it’s important to stagger the joints for a more professional look. This will also help prevent the boards from warping or splitting.
To stagger the joints, start by installing the first board at one end of the deck. Then, install the next board so that it’s offset from the first board by a half-joist width. Make sure to use a level to make sure the boards are straight and secure them in place with screws.
Repeat this process for the rest of the decking boards.
5. Use a spirit level to ensure the boards are straight
When installing your decking boards, it’s important to make sure they are straight. To do this, use a spirit level to check the board for any bumps or hills. If necessary, use a shovel or rake to fix them before installing the screws.
Start at one end and fix the first board in place with nails or screws. Work your way along, ensuring each board is fixed securely before moving on. Cut any boards that need to be shorter using a saw.

6. Avoid installing your decking boards too close to the edge
When installing your decking boards, it’s important to avoid installing them too close to the edge. This will help prevent them from warping or splitting.
To avoid this, leave a gap of at least six inches between the board and the edge of the deck. If you’re installing a railing, make sure to leave even more space between the board and the railing.
7. Finish up by installing trim boards
Once you have installed all of your decking boards, it’s time to install the trim boards. This will help give your deck a more polished look.
There are many different types of trim boards, so choose the one that best matches your deck’s style. Then, use a level to make sure it’s straight and secure it in place with screws.
If you’re installing a railing, install the trim boards around the top and bottom of the railing. This will help protect the decking board from moisture and UV damage.

There are two main ways to install decking boards – with nails or screws. Nails are cheaper and faster to use, but they can easily pop out over time. Deck screws are more expensive, but they hold the board in place better and don’t tend to pop out as easily.
When deciding which type of fastener to use, it’s important to consider the climate and weather conditions where you live. If you live in an area with high winds, screws are a better option than nails. If you live in a humid area, nails may be a better option since screws can rust.
Whichever type of fastener you choose, make sure to pre drill the holes before inserting the nails or screws. This will help prevent the wood from splitting.
