Sydney Deck Builder, Built Around Lasting Quality
Most deck problems in Sydney do not show up on day one. They show up eighteen months later, when the joists start to twist, the boards cup after the first hot summer, or the frame was never squared properly, so every join has a small gap that gets worse every year. A deck builder who understands Sydney's climate designs around that from the beginning, not after the callback.
SB Higgs Projects has spent years learning what actually works across this city's varied conditions, from salt air on the Northern Beaches to reactive clay soils further inland. Every timber deck we build starts with a proper site assessment. We check drainage, sun exposure, soil movement and how the finished structure will sit against your existing home before a single joist goes down. That groundwork is what separates a deck that looks good in the brochure from one that still looks good in ten years.
We are not a decking supplier selling you boards and leaving you to work out the rest. We are a licensed carpentry team that designs, builds and finishes your deck end to end, and we stand behind the result with a workmanship warranty.

Why Sydney Homeowners Choose SB Higgs For Timber Decking
Choosing a deck builder is not just about who can start the soonest. It is about who will still take your call if something needs attention in year three. Here is what that looks like in practice.
Built Around Your Property
Every deck we build is designed around your property, your intended use and your budget. Pool surrounds, elevated entertaining areas, sloping blocks and tight courtyards each need a genuinely different approach, and we plan carefully for that from the first site visit.
Licensed. Insured. Accountable.
Your project is completed by a qualified NSW carpenter, Licence No. 474662C, with appropriate public liability insurance in place throughout. That protects you as the homeowner and ensures every piece of structural work meets the National Construction Code.
Premium Materials
We work with Australian hardwoods and composite decking boards, carefully matched to your specific site conditions and sun exposure, rather than simply whatever material happens to be cheapest that particular week.
One Fixed Price, No Surprises
You get a clear scope, a genuinely fixed price and a realistic timeline before construction ever begins. No vague estimates, no "we'll work it out as we go," and no surprise costs or awkward conversations halfway through your build. What we quote is what you pay.
Backed By Our Warranty
We back every piece of our craftsmanship with a proper workmanship warranty, giving you real confidence the finished deck is built to last for years, not just built to pass inspection on handover day. If something genuinely needs attention down the track, we stand behind the work and sort it.
Council Approval Support
Setbacks, height limits and exempt development rules can be confusing. We help you understand what applies to your project and manage the paperwork where required, so approvals do not stall your build.
Timber Decking Services We Offer Across Sydney
Every deck project is different. We match the scope of work to the size of your
outdoor space, your budget, and what your property actually needs, from a first conversation through to a fully finished, multi-level build.
Important Note
Timber decking costs in Sydney depend on the size of the deck, the material selected, the height above ground, and any council approval requirements. Accurate pricing follows a free on-site consultation..

Our Process
How We Build Your Deck
Building a deck looks simple from the footpath, just boards on a frame. In reality, every stage decides how that structure survives Sydney's weather, holds its shape over time, and feels underfoot years from now. Get one step wrong early, and no amount of finishing work fixes it later.
Design And Site Assessment
We visit your property to assess soil conditions, drainage and access, then walk through design options and material choices suited to your home, your budget and how you actually plan to use the space.
Framing And Joists
Joist spacing must match your chosen decking material. Wider composite boards and narrower hardwood boards need different spacing to prevent bounce or sagging. We square every frame properly first, since an out-of-square start only gets worse.
Installing The Decking Boards
Boards are laid from the outside in, working toward the house, so finished cuts stay least visible. For composite boards, we use a pilot hole for every screw near the edge, keeping each fastener flush and split-free.
Gaps And Expansion Allowance
Timber and composite behave differently in Sydney's heat. Natural timber expands when cold and contracts when hot, moving across its width. Composite expands lengthways in hot weather, so we leave a 5mm gap and roughly 1mm per metre expansion allowance.
Finishing And Final Check
Every fastener and screw is checked before handover. We ensure the finished deck is level, secure and genuinely ready for use, then walk you through small but important maintenance steps before we leave.
Security Verification
Every quote request submitted through our website runs through a short security verification step, blocking spam and malicious bots, not genuine Sydney homeowners. Our system verifies each enquiry automatically, and once verification is successful, it goes straight to a real carpenter, with a callback within one business day.
Decking Boards And Composite Decking Options
The right decking material depends on your budget, your maintenance appetite and how exposed your deck is to sun, salt air and foot traffic. We install both timber and composite decking boards across Sydney, and we will always recommend the option that suits your property rather than the one with the highest margin.
| Material | Best For | Maintenance |
|---|---|---|
| Spotted Gum | Exposed outdoor areas, premium natural finish | Annual oil, moderate |
| Blackbutt | Contemporary, lighter-toned decks | Annual oil, moderate |
| Merbau | Deep-toned decks, pool surrounds | Annual oil, watch for tannin bleed early on |
| Treated Pine | Structural framing, budget-conscious builds | Low cost, needs regular sealing |
| Composite Decking | Low-maintenance, high-traffic decks | Hose down, no oiling or sanding |
Composite decking has become a popular choice for Sydney homeowners who want the look of timber without the upkeep. It resists fading, splintering and insect damage, and it holds its colour through harsh UV exposure far better than untreated softwoods. Timber decking, on the other hand, still wins on natural warmth and character, and a well-maintained hardwood deck can outlast a poorly installed composite one by decades.
We will walk you through the trade-offs during your free consultation, so you choose the decking material that actually suits how you live, not just how the sample board displayed in the showroom looks.
Deck Maintenance Tips
Keeping Your Sydney Deck Ready For Every Season
A well-built deck still needs a small amount of ongoing care, and knowing what to expect helps you budget for it from the beginning.
- Natural timber decking expands in cold weather and contracts in hot weather, mostly across the width of each board. Small seasonal movement is normal and expected.
- Composite boards move differently again, expanding lengthways in hot conditions, which is why correct expansion gaps at installation matter so much.
- Oil natural timber decking on all four sides, not just the top face, to protect it evenly and stop moisture creeping in through the edges.
- Sweep or blow debris off your deck regularly, and remove leaf litter trapped between boards before it holds moisture against the timber and speeds up wear.
- Hosing off composite decking is the easiest way to keep it clean. It does not need oiling, sanding or restaining the way natural timber does.
- Check fasteners and screws every year or two, particularly on older decks, since small movements over time can work fixings loose.
Depending on the timber species you choose, maintenance frequency will change, so remember we cover this in detail during your consultation rather than leaving you to figure it out after the build is finished.

Frequently Asked Questions
What is the average price to install a deck in Sydney?
Most professionally installed decks in Sydney sit between roughly $250 and $700 per square metre, depending on the material. Treated pine sits at the lower end, hardwoods like Spotted Gum and Merbau sit in the middle, and premium composite boards can run higher again. A typical residential deck of 20 to 40 square metres generally lands between $8,000 and $25,000 fully installed, though site access, height above ground and structural complexity all move that number.
What is the 3/4/5 rule deck builders use?
The 3/4/5 rule is a simple way to check that a deck frame is perfectly square without any advanced tools. Measure 3 units along one side of the frame from a corner, 4 units along the adjacent side, and if the diagonal between those two points measures exactly 5 units, the corner is square. It is based on basic geometry, and every experienced carpenter uses some version of it before fixing joists in place, because an out-of-square frame causes problems in every stage that follows.
Can you install a deck yourself in Sydney?
Small, low-level deck repairs are within reach for a confident DIYer. A full new deck build in Sydney is a different matter. It involves structural framing, correct footing depths, compliance with the National Construction Code, and in many cases, council approval. Getting any of that wrong can mean an unsafe structure or a costly rebuild, which is why most Sydney homeowners bring in a licensed carpenter for anything beyond minor maintenance.
How long does it take to build a deck in Sydney?
Most residential timber decks take between one and three weeks to build, depending on size, ground conditions and whether council approval is required first. Straightforward courtyard decks move faster, while multi-level or sloping-block builds take longer due to additional framing and footing work.
How much should it cost to build a deck in Sydney?
There is no single fixed figure, because material choice, structural complexity and site conditions all shift the price. As a general guide, budget-conscious treated pine decks start lower, mid-range hardwood decks sit in the middle, and premium composite or elevated designs sit at the top of the range. The only reliable way to get an accurate number is a proper on-site assessment, which is why we offer one for free.
Is composite decking better than timber decking?
Neither is universally better, they suit different priorities. Composite decking needs far less upkeep, resists fading and never needs oiling. Natural timber decking offers a warmer, more traditional look and can last just as long, or longer, with proper annual maintenance. The right choice depends on how much time you want to spend maintaining it.
How long does timber decking last?
A well-built, well-maintained hardwood deck can last 20 to 30 years or more. Lifespan depends on the timber species, how exposed it is to sun and salt air, and whether it gets oiled and checked regularly, as outlined in our maintenance section above.
Do you need a permit to build a deck in Australia?
Not always. Some smaller, lower decks in NSW may qualify as exempt development if they meet specific requirements around height, boundary setbacks and structural standards. Larger, higher or more complex builds usually need council approval or a complying development certificate before work starts. Because the rules depend on your property, its zoning and its location, we confirm the correct approval pathway with you before any construction begins, so there are no compliance surprises later.
