Cost of Decking

Decks are small platforms attached to the outside of a house for use by people, plants, and so on. Decks are typically surrounded by railings, the decking material the deck is constructed with, and any furniture it contains. A properly designed and built deck can increase the value of a house by several thousand dollars. A poorly constructed one may cost you more in repairs over its lifetime than it adds to your home’s value.

Decks are usually made from lumber, although alternatives such as recycled plastic lumber are increasingly being used. The deck price usually depends on the overall floor space and deck construction process.

Decking Cost

In Australia, decking can vary and can be as low as $2,000, or up to $30,000 or more for a 100 m2 area.

The price of decks depends on various factors: quality and type of construction materials (lumber or synthetic wood), size and design (simple rectangular shapes to elaborate curved designs with multiple levels and non-rectangular plan) and there are also different types of decks (built-in, freestanding and dock decks).

The most expensive decking is composite decking.

In general, good quality lumbers such as cedar, redwood or ipe are more expensive than alternative choices such as pressure-treated pine or recycled plastic lumber.

Decking Timber Prices

It’s important to know what kind of timber you’re interested in. In Australia, the most common types of lumber used for decks are:

  • Pressure-treated pine
  • Hardwood (such as Merbau, jarrah or ironbark) and
  • Softwood (such as redwood, cedar or treated pine)

Pressure-treated Pine Decking

Pressure-treated pine is a relatively inexpensive decking material. It’s a combination of a wood preservative and a particular board core. Some people refer to this type of decking as CCA, which stands for chromated copper arsenate.

It has good strength properties but it may be sealed with a water repellent every one to three years because it may rot when exposed to moisture. If untreated, pressure-treated pine usually lasts from 10 to15 years.

In the long term, pressure-treated pine may be a less expensive choice because it won’t need to be replaced as often as other types of decking material.

Hardwood Timber Decking

Hardwood is a more expensive option than treated pine or recycled plastic lumber but it’s much more attractive and may have a longer life span if properly maintained. At the same time, hardwoods can warp and check (cracks between boards). If you choose this type of wood, make sure that you treat them with a suitable finish every year after installation and every two to four years after that.

Softwood Decking

Softwood is available in unchinked planks which are easier to saw and nail through compared to harder woods, however, these don’t hold their shape well over time and may need to be replaced more often.
