Decking in Sydney

The honest starting point for decking in Sydney is that you are dealing with councils that each interpret the same state controls slightly differently. Everything we specify follows from working with that rather than pretending it is not there.

Sydney is not a uniform place to work. Between everything from flat river plain to steep sandstone escarpment and reactive shale clay in the west, sandstone and sand through the coast and north, two properties in the same street can need quite different approaches to the same job.

Ask three contractors for decking in Sydney and you may get three different answers. The difference usually comes down to whether anyone has looked at ground conditions that change completely between one side of the basin and the other before pricing the job.

What We Specify and Why

Everything we install carries a manufacturer specification, and we install to it. Warranty claims fail on installation detail far more often than on product defect.

Material selection here is driven by exposure and by use. Once you allow for access constraints that vary from a wide western verge to an inner-west rear lane, the finish and the fixings decide the service life more than the substrate does.

  • Joist spacing is set by the board thickness and the direction of lay, and closing it up is what stops boards feeling springy.
  • A deck is only as good as its substructure, and the substructure is what nobody sees when comparing quotes.
  • Composite boards expand along their length more than timber, so end gaps are set differently.
  • A deck built low to the ground needs ventilation underneath or the substructure will hold moisture and fail early.
  • Merbau bleeds tannin for the first few rains, which is why a pre-coat before laying saves staining on light paving below.

Site Logistics in Sydney

We agree the working hours and the access route with you at the start. On the tighter Sydney streets that conversation saves a day, and it saves the relationship with the neighbours.

Where machine access is not possible, we say so in the quote rather than discovering it on the morning. Hand excavation on reactive shale clay in the west, sandstone and sand through the coast and north is slow and it should be priced honestly.

How We Approach a Sydney Job

We photograph the site before we start and again at completion. On a Sydney job that record settles most questions about what was there and what changed.

We set out the whole run first, mark the levels, and agree the approach on site before anything is ordered. Once material is cut for a Sydney job it is committed.

  • Galvanised and hardwood substructure
  • Pool surround decking
  • Composite and capped composite boards
  • Merbau and spotted gum hardwood decks
  • Hidden fixing and pre-oiled finishes
  • Elevated decks with balustrade

The Decking Formats We Build

Substructure

Galvanised steel or treated hardwood framing sized for span and for the ground beneath it.

Hardwood Decking

Merbau, spotted gum and blackbutt boards, oiled and re-oiled to hold their colour.

Steps and Landings

Transitions between levels set out so the rise is consistent and comfortable.

Pool Decking

Deck surfaces around a pool detailed for slip resistance and splash drainage.

Elevated Decks

Raised decks with balustrade where the living floor sits well above the yard.

Screening and Skirts

Skirting and screening that closes the underside without trapping moisture.

Signs It Is Time To Do Something

We are based at Wentworthville and Sydney is well inside our regular run, so a site visit is a short trip rather than a scheduling problem.

  • A substructure that has rotted where it sat in contact with damp ground
  • A springy feel from joists spanning further than they should
  • A deck that traps moisture underneath because it was built too low without ventilation
  • Balustrade that no longer meets current height and infill expectations

Frequently Asked Decking Questions

The boards are rarely what fails first. On the sort of ground around Sydney, described as reactive shale clay in the west, sandstone and sand through the coast and north, it is the substructure and the connection to the ground that determines lifespan. Galvanised framing or treated hardwood on proper footings with ventilation underneath will outlast the deck surface by a wide margin.

It depends on height and location. A low deck is often exempt development under the State Environmental Planning Policy for exempt and complying development, while a raised deck, or one close to a boundary, frequently is not. Heritage and bushfire mapping also change the answer. Check the specifics with the relevant local council before you build.

Realistically an oil every year or two, more on a full sun aspect. The first coat after installation matters most because the timber is still shedding moisture. In Sydney, expect a shorter interval on a site dealing with access constraints that vary from a wide western verge to an inner-west rear lane. If that sounds like more than you want to commit to, composite is the honest recommendation.

Most decks here are dealing with it. On everything from flat river plain to steep sandstone escarpment, a deck is often the cheapest way to create level usable space, because the alternative is retaining and fill. The substructure carries the level change and the finished surface sits flush with the house floor.

Hardwood looks better and costs less to install, and it needs oiling to hold its colour. Composite costs more up front and asks for almost nothing afterwards. In Sydney, what usually tips the decision is access constraints that vary from a wide western verge to an inner-west rear lane, because that determines how quickly an oiled surface breaks down and how often you would be back on your knees with a brush.
