Timber Decking

Timber decking has always been a popular garden feature that extends your outside living space. Versatile in nature, decking can accommodate uneven terrain to make functional year-round outdoor spaces.

Wooden decking is customisable to your garden. It can be used to create a raised seating area, as an impressive walkway or as a transitional feature that takes the user across different ground levels. Use our timber decking calculator to easily work out how much decking you require.​

Product Specification

Our range of premium quality timber decking is made from pressure treated softwood, which is guaranteed for 25 years against rot and insect attack. Our decking joists and posts are treated with a more concentrated solution of our unique Jakcure® timber treatment to ensure a long life in ground contact. Where possible, avoid cutting, drilling or notching any timber that will be in-ground, as per our 25 year Jakcure® terms and conditions. If occasional sections do have to be cut, then Cut Treatment should be applied liberally.

  • All timber decking boards are grooved to help create a safer, slip resistant surface.
  • Standard decking boards are planed from 100x25mm section boards giving a finished size of approx 95x21mm.
  • Heavy Decking Boards are planed from 150x32mm section boards giving a finished size of approx 145x28mm.
  • ​Our decking joists are treated with a more concentrated solution of our unique timber treatment to ensure a long life in contact with the ground.
  • Timber is a natural product and can shrink/expand in varying weather conditions

For heavy duty, high traffic areas, we recommend our heavy-duty timber decking boards. 

We also supply slip resistant decking boards, with added resin and aggregate mixture (grit) which ensure significantly more grip. 

To frame your decking, or make it safer if it is raised, we recommend adding timber balustrade

Taking care of decking

Periodic cleaning to remove moss and lichen as this will reduce the risk of slipping. Be aware that during the natural weathering process boards can occasionally splinter slightly so we recommend not to walk on the deck without footwear.

Planning and Building a Deck

Fence post installation

We supply timber decking kits, which are complete sets of everything you need to build a deck. We have three standard sizes available, 1.80m x1.80m, 1.80m x 3.60m and 3.60m x 3.60m

Decking Kits

Planning Permission, general advice:

Putting up a wooden decking area, or other raised platforms, in your garden is permitted development providing:

  • They are no more the 300mm above the ground
  • Together with other extensions, outbuildings etc, they cover no more than 50 per cent of the garden area.


Slip-Resistant Wooden Deck Boards

We can also supply super slip-resistant deck boards in 3.6m lengths.

Our timber decking boards are grooved to reduce slip risk in normal use, but there will always be limitations of a timber only deck board, especially as they weather and algae grows on them. The addition of two grit strips to each board significantly improves the slip resistant properties in all weathers. This makes them an ideal choice for steps and areas of high traffic. The downside is that the grit strips do sit proud of the surface so if someone falls on the grit, it could graze the skin.
