Decking Joists
Creating the framework for your decking, deck joists are an essential part of any decking project. Selecting the correct joist is crucial to the longevity of your deck and Stewart Timber is here to help!
Our joists are made of durable, pressure treated timber that is sustainably sourced from FSC suppliers. We select pressure treated timber as it gives your joists a longer life, protecting it from harsh weather conditions, harmful pests and wood rot!
Once your deck is complete we recommend treating it with deck oil to seal in all the natural oils to give it an added layer of protection! To complete the rest of your decking, we suggest exploring our boards, posts and panels.

Decking - FAQs
How many years will decking last?
Depending on how well you care for your wooden deck, it can last 10-25 years. Cleaning, oiling, and refinishing it will help it last longer. Our composite decking has a 15 year warranty and doesn’t need as much maintenance to keep it sturdy for years to come.
Do you need planning permission for decking in Scotland?
You usually don’t need planning permission for constructing a deck in your garden in Scotland. If your deck is no more than 50cm from the ground, it’s wholly behind the principal elevation or side elevation if road facing, if it’s not in a conservation area (unless the deck is under 4 metres squared), and your home is not a listed building, then you don’t need planning permission.
What is the cheapest decking option?
The cheapest material for decking is wood. Composite decking is slightly more expensive, though you don’t need to spend as much money maintaining it over its lifetime.
How much does decking cost?
The cost of decking depends on the type of decking material, your design, its size, and the extra products you need to bring it all together. Our basic decking kits begin at £380. Larger projects with stairs, spindles/panels and handrails can cost into the £1000s.
