1. Plan and mark out the area
- decide on the deck size
- mark the layout clearly
- check any local rules that apply before you build
- use the deck calculator for an early material estimate
2. Prepare the site
- excavate and level where needed
- improve drainage with gravel or another suitable base
- install the support system that fits the project
3. Build the framing
- install the main supports
- add the joists with appropriate spacing
- check the structure for level and stability
4. Install the deck boards
- start from a straight reference line
- fasten the boards with consistent spacing
- cut carefully around edges and corners
5. Finish the deck
- smooth rough edges if needed
- apply stain, oil, paint, or another appropriate finish
- make sure the full deck is secure and ready for use
6. Add furniture and final details
Lighting, planters, and outdoor furniture can make the finished deck feel more complete and easier to use.
