Build a better deck
A timber deck extends your living space into the garden. Whether you are building a simple patio deck, a raised terrace or a large commercial boardwalk, we supply every part: decking boards, joists, supports, screws and finishes, delivered free across the UK.
Choose your decking boards
- Green treated softwood decking: pressure treated UC3/UC4 pine, great value and easy to work, with reeded or flat faces.
- Brown treated softwood decking: the same durable pine with a warm brown colour.
- Anti-slip decking: boards with gritted inserts for safe grip in wet weather, ideal for steps, ramps, pool surrounds and public spaces. See anti-slip decking.
- Austrian and Siberian larch decking: naturally durable, dense softwood that needs no chemical treatment, including pre-aged silver-grey boards.
- Thermowood decking: heat treated redwood that is stable, durable and resin-free.
- Yellow Balau hardwood decking: a very hard, dense tropical hardwood for premium, long-lasting decks.
Sleepers for landscaping
Use oak sleepers (100 x 200mm, PEFC certified) or green treated softwood sleepers for raised beds, retaining walls, steps, borders and garden edging.
Decking substructure
A deck is only as good as the frame beneath it. Use treated C24 structural joists (for example 47 x 150mm) at 400mm centres for domestic decks, with adjustable supports or posts, a weed membrane and stainless or coated decking screws. See C24 timber.
Smooth or reeded decking?
Reeded (grooved) faces help water drain and add texture; smooth faces are more comfortable barefoot and easier to clean. Many of our boards are reversible, so you can choose on site. Anti-slip inserts give the best grip of all.
Decking FAQs
How far apart should decking joists be?
400mm centres for most domestic decks, closer for diagonal boards or heavy use.
Should I leave gaps between deck boards?
Yes, 5 to 6mm between boards lets water drain and allows for movement.
How do I stop decking going slippery?
Keep it clean, allow airflow underneath and choose anti-slip boards in shady or wet areas.
Do I need to oil my deck?
Oiling once or twice a year with a decking oil protects the timber and keeps its colour. See finishes.
