Building a simple deck frame, or decking subframe, that you’re laying on level ground is easy if you take time to prepare and get all the things you need. We’ll go through the steps on how to build a deck frame here.
Tools and equipment
To get building your deck frame, you’ll need:
- Decking joists
- Coach screws
- Coach bolts
- Combi drill
- Socket set
- A saw suitable for your project and the thickness of the timber
- Decking preservative
- Sandpaper or sander
Build your subframe
- Measure your deck frame and cut to size if necessary.
- Make 2 pencil marks on each end of the frame’s 2 outer joists to mark where the coach screws will go. They need to align with the centre of the adjoining outer joist. Then, use a flat wood drill bit to drill recesses into each mark. Make them the same depth of the screws that your using’s head and wide enough for a ratchet or socket to tighten them.
- Using a thinner drill bit, line up the outer joists and drill a pilot hole through the middle of the recess. These pilot holes act as a guide for the screws and stops them from splitting the wood.
- Fit the coach screws with either a drill driver or socket and ratchet.
- Repeat the process for the inner joists once you’ve assembled the outer frame.
IMPORTANT: While you’re building your deck frame and the decking itself, remember to cover all pilot holes and ends of timber in decking preservative to ensure that your decking remains structurally sound for as long as possible.
Though relatively simple, building a deck frame and the decking will take some time. It would be much quicker and easier to get a professional in to do it, who could represent more value for money.
