Experienced Decking in Edinburgh
Decking work includes groundwork where required, structural framing, deck boards, steps, edge details, and shaped layouts that suit the garden. A well-built deck needs proper support, sound fixing, and sensible design so it stays stable, drains well, and stands up to regular use and Scottish weather. Choosing between timber and composite is usually the first decision, and we give honest advice rather than a blanket promise: a treated softwood deck gives a good few years of service and rewards regular care, while a quality composite board can last considerably longer, often fifteen years or more, with very little upkeep.
We start by checking levels, ground condition, access, drainage, and how the deck needs to connect with the rest of the garden. A deck is often the neatest answer to a garden that changes level, from sloping suburban plots to the stepped townhouse and colony gardens common across Edinburgh, where a raised platform creates usable flat space where there was none. From there, the work is carried out in the right order and tied in naturally with related services such as Patio Installation and Garden Landscaping, so the finished deck feels properly built and properly placed.

Types of Decking We Build in Edinburgh
-
Treated softwood decking
A dependable and cost-effective option for residential gardens. We use thick, pressure-treated European redwood boards that resist insect attack and damp rot. The boards are fixed to the structural joists using stainless steel deck screws, countersunk neatly to provide a smooth, splinter-free surface underfoot. Softwood benefits from a coat of decking oil, stain, or sealer every year or two to hold its colour and keep the weather out, and we can advise on the right product.
-
Capped composite decking
For low-maintenance outdoor living, composite boards combine recycled wood fibres with durable polymers. These boards do not warp, split, or require annual staining, making them well suited to the damp Scottish climate. Many of the ranges we fit have an anti-slip textured or grooved surface, which is well worth having where boards stay damp for much of the year. We install them using hidden fixing clips between the board grooves, delivering a clean finish with no visible screw heads.
-
Elevated and raised decks
If the back door sits well above garden level, we can build a raised structural platform. We set heavy-duty support posts into deep concrete pockets and brace the framework using structural bolts. These elevated designs include secure perimeter balustrades, in timber, glass, or metal to suit the look you want, and custom-built steps to provide safe access down to the lawn.
-
Multi-level decking systems
To make the most of sloping gardens, we construct split-level decks that follow the natural contours of the land. We build separate, interconnected timber frameworks that create distinct zones for dining and seating. This structural woodwork turns awkward, steep banks into functional tiered outdoor spaces.
-
Hot tub decking platforms
Supporting the weight of a hot tub requires specialised structural framing. We build an independent, reinforced base directly beneath the tub location to bear the load safely. We then frame the finish decking flush around the top edge of the tub, keeping all maintenance access hatches fully accessible.
-
Hardwood decking
For an exceptionally long-lasting finish, hardwoods like Balau or Ipe offer dense, natural durability and high scratch resistance. These tight-grained woods resist moisture absorption and age to a classic silver-grey tone if left un-oiled. We pre-drill every board to ensure precision fixing without splitting the wood.

What Our Clients Say
-
Graeme — CorstorphineKingsknowe Building & Landscaping built a large raised composite deck outside our kitchen door. The sub-frame is solid with zero bounce, and the hidden fixings give a clean finish. The team worked through difficult weather to get it done.
-
Paul — KirklistonWe replaced an old deck that had started to move and rot in places. The new structure is much more solid, the layout works better with the garden, and the attention to the frame and edging was clear throughout.
-
Helen — BalernoOur decking project was tied in with other garden work and it all came together really well. The levels into the patio and lawn were handled properly, which has made the garden feel much more thought through.
How We Do It
-
Site visit and planning
The first step is checking the garden, levels, access, ground condition, and how the deck is meant to be used. That helps shape the layout, the height of the structure, and the best way to tie it into the rest of the space.
-
Set-out and structural preparation
Before any boards are fixed, the area needs to be set out properly and the support structure planned to suit the site. This stage is where the deck gets its strength, so the base, frame, and support points all need to be right.
-
Deck build and finishing details
Once the structure is ready, the deck boards, steps, edges, and transitions are built out carefully. Attention to spacing, line, fixing, and finish makes a big difference to how the deck looks and feels in use.
-
Final checks and completion
At the end of the job, the deck is checked over for stability, finish, alignment, and overall usability. That final stage matters because a deck should feel solid and well judged from the first step onto it.
Frequently Asked Questions
-
Yes. Every deck we build comes with our own workmanship guarantee, so if the structure moves, a board lifts or anything fails because of how it was put together, we return and put it right. The work is carried out to the Scottish Building Standards, and before we hand the deck over we walk it through with you, checking the frame, the fixings, the steps and the stability underfoot so you can be sure it has been built properly.
-
The materials carry their own manufacturer warranties, and those sit alongside our workmanship cover rather than replacing it. The C24 timber sub-frames are pressure treated with guaranteed protection against rot and insect attack, and the composite boards come with long manufacturer guarantees against warping and fading, so as long as they are installed the way we fit them, you are covered on both the structure and the surface.
-
The support structure matters just as much as the surface boards. A properly built treated timber joist subframe, fixed with corrosion-resistant stainless or galvanised deck screws and set to true levels, is what keeps a deck solid underfoot. If the frame, fixings, or support points are not right, the deck can start to move, feel bouncy, or wear out much sooner than it should.
-
The timescale depends on the size of the deck, the height and layout, access to the garden, and whether steps or other linked garden work are included. A straightforward deck can be completed more quickly than a larger build with level changes and extra detailing.
-
The total cost depends on whether treated softwood, premium hardwood, or capped composite boards are chosen. Composite options have a higher upfront cost but require no ongoing maintenance, whereas softwood is more economical initially. We give a detailed price after measuring the garden.
-
C24 is a premium grade of structural timber with fewer knots and a denser grain than standard C16 wood. We use C24-grade treated timber for our main structural deck frames because it handles higher weight loads and spans wider gaps without bending or sagging over time.
-
Standard ground-level decks rarely require planning permission. However, if the platform sits more than three hundred millimetres above the ground, covers more than half the garden area, or affects the privacy of neighbours, planning permission may be needed before construction begins.
-
We use pressure-treated structural timbers designed for ground contact and coat all cut ends with wood preservative on site. We also apply protective joist tape across the top of the framework to prevent rainwater from pooling in screw holes, and ensure there is a clear ventilation gap beneath the deck.
-
No outdoor surface is completely non-slip when covered in ice or wet leaves, but the anti-slip decking boards we fit feature deep moulded textures that give good grip compared with older products, which matters through wet Scottish winters. Keeping the surface clear of organic debris prevents algae growth, which is the main cause of slipperiness in wet conditions.
