Find a deck builder in Adelaide

A good timber deck extends your living space outdoors, and in Adelaide it gets used for most of the year. Whether it’s a low deck off the back door, a raised deck on a sloping block or a deck around a pool, tell us what you have in mind and we’ll connect you with a local carpenter who builds decks to talk it through and quote.

Carpenter Adelaide is a free referral service. We don’t build decks ourselves: the carpenter quotes, contracts and does the work, and you deal with them directly.

Which timber should you choose for your deck?

Hardwoods are the usual choice for Adelaide decks because they’re dense, hard-wearing and handle the heat well.

Merbau

Merbau is a rich reddish-brown hardwood that’s been a favourite for Australian decks for decades. It’s stable, durable and takes oil well. Expect some tannin bleed in the first few months: rain can wash a brown stain from new boards onto paving, so ask your carpenter how they manage it.

Blackbutt

Blackbutt is an Australian hardwood with a pale, golden-brown colour that suits modern homes. It’s strong and durable and is a popular local alternative to imported timbers.

Other options

Spotted gum, jarrah and treated pine are also common. Treated pine is the budget option and is often used for the hidden frame under a hardwood deck. If you want to skip the oiling altogether, look at composite decking.

For a deeper comparison of colours and species, see our guide to wood decking types and colours.

Looking after a timber deck

Timber decks need regular care to stay looking good. Most Adelaide decks need a clean and a fresh coat of decking oil about once a year. Keep leaves and dirt from building up between the boards, and check for loose nails or screws each spring.

If your deck has gone grey, has a few cracked boards or feels bouncy underfoot, a carpenter can tell you whether it can be restored or needs rebuilding. Mention the age and condition of your deck in your enquiry.

What to ask before you sign

  • Which timber species and grade, and what size boards?
  • What’s the frame made of, and how far apart are the joists?
  • How will the boards be fixed: face-nailed, screwed or hidden clips?
  • Does the quote include oiling, steps, balustrades and removing an old deck?
  • Does the deck need development approval, and who will lodge it?

Our guide on how much it costs to build a timber deck explains what affects the price.

  2. We refer a local carpenter

    We pass your enquiry to a recommended carpenter who does that kind of work in your part of Adelaide. Every carpenter we refer holds a current South Australian building work contractor licence and public liability insurance.

  3. The carpenter contacts you

    They get in touch to talk through the job, arrange a site visit if it’s needed and give you a quote.

  4. You decide

    There’s no obligation. Compare the quote, check the carpenter’s licence and only go ahead if you’re happy with the price, design and timing.

How to choose a carpenter in Adelaide

Choose a carpenter who holds a current South Australian building work contractor licence and public liability insurance, gives you a written, itemised quote, and tells you who will lodge any council approval.

Every carpenter we refer meets our criteria (a current South Australian building work contractor licence and public liability insurance) when we add them to our list, but it’s still worth checking for yourself. The statutory warranties under the Building Work Contractors Act 1995 (SA) come from the carpenter who does the work, not from us.

Checks before you sign

  1. Check the carpenter’s building work contractor licence on the Consumer and Business Services (CBS) website.
  2. Ask for a current certificate of currency for their public liability insurance.
  3. Get a written quote listing the materials, sizes, inclusions, exclusions and GST.
  4. For decks, pergolas and structural work, ask whether you need development approval and who will lodge it through PlanSA.
  5. Ask whether site preparation, engineering, rubbish removal and making good are included.
  6. For domestic building work of $20,000 or more that needs development approval, the builder must take out building indemnity insurance and give you the certificate before work starts.

Timber Decking: common questions

What timber is best for a deck in Adelaide?

Merbau and blackbutt are two of the most popular hardwoods for Adelaide decks. Both are dense and durable, and they cope well with hot, dry summers when they’re oiled regularly. Spotted gum and treated pine are other common choices. Your carpenter can talk you through the look, price and upkeep of each.

How often does a timber deck need oiling?

Most hardwood decks in Adelaide need cleaning and re-oiling about once a year, or more often if they get full afternoon sun. A deck that’s left to go grey isn’t ruined, but the boards will dry out and can crack or cup over time.

Can an old deck be restored instead of replaced?

Often, yes. If the frame (bearers, joists and footings) is sound, a carpenter can replace damaged boards, re-fix loose ones, sand and re-oil the deck. If the frame is rotten or the footings have moved, it’s usually time to rebuild. Tell us what condition your deck is in and the carpenter will advise after looking at it.

Do I need council approval for a deck?

It depends. In South Australia, whether a deck needs development approval depends mainly on how high the floor is off the ground, its size and where it sits on your block. Higher decks generally need approval and a balustrade. Applications are lodged through PlanSA, so ask your carpenter who will lodge yours, or check with your council.

Timber or composite: which should I choose?

Timber looks and feels natural and usually costs less to buy, but it needs regular oiling. Composite costs more upfront but needs little more than a wash. See our composite decking page or our timber vs composite guide to compare them.
