Reliable Jarrah Decking in Sydney

At Urban Arch Building, we pride ourselves on providing unmatched outdoor decking quality, durability, and customer service (that’s why we were rated Sydney’s #1 deck-building experts). 

But to us, crafting decks is more than just a job. As a father-son duo, we know how important family is and how vital it is to have a home that truly helps you come together and break bread. That’s why we’re dedicated to providing outdoor timber decking that will serve your family today, tomorrow, and for years to come. 

Our jarrah decking, in particular, is sustainably harvested from the jarrah tree that’s native to south-west Australia. It offers a stunning rich brown-red or burgundy hue that’s sure to warm up any outdoor space while providing unmatched strength and durability over time. Jarrah is also insect-resistant, fire-resistant, and weather-resistant, making it the perfect decking option for those who live in Sydney where temperatures fluctuate from bushfire-conditions to wet and windy winters. 

When you choose a jarrah deck, you’re promising you and your loved ones a rich, warm, and lasting backyard deck experience for decades to come. If you would like to know more information, please don’t hesitate to reach out for free samples, expert advice, or a 100% obligation-free quote

Why Choose Jarrah Decking?

Originating in southwest Australia, Jarrah has been a favorite Aussie timber since the 1980s. It has made an appearance in a range of different products — including furniture, decking, and construction — and it has been used often in marinas, businesses, commercial buildings, and homes.

One of the most attractive qualities of jarrah wood is its beautiful, dynamic colour variations (it can range from a rich red all the way through to a striking reddish-brown). What’s more, this durable wood has an attractive grain and a high resistance to termites, weather damage, and other natural elements.

This makes it the perfect choice for anyone in Sydney’s beach communities who is looking to up their decking game and find a timber option that’s resistant to ocean water and salty air. What’s more, the burnt sienna, earthy tones of this native wood lend an instant lived-in feel that you won’t get with other wood options.

Benefits of Jarrah Decking

Deciding to install a new deck is the easy part – choosing the right timber is where things get tricky. While jarrah hardwood timber is known for its strength and durability, there are plenty of other exciting reasons to wake up to a jarrah verandah or patio.

As a leading timber decking material across Sydney, the following advantages are only a phone call away.

As one of Australia’s most prized timbers, a jarrah deck can last up to 25 years (with proper care and maintenance) and it’s easy to see why more and more Sydneysiders are refusing to work with anything but jarrah.

How Much Does Jarrah Decking Cost?

Because of its popularity and rarity, jarrah is a fairly expensive timber option. Prices generally range from $180 to $320/m2. 

Outside of the raw timber cost, you’ll need to factor in installation costs, labour, and any support structures when determining your overall cost. That said, we always recommend that you do your research and make sure that you choose a licensed, seasoned profession for your decking needs. 

Your home is your safe space, and any kind of home improvement project should be approached with care and consideration.

How Long Will It Take to Install a New Jarrah Deck?

Ok, so let’s talk about timelines. 

There are many factors to consider when establishing the timeline of your decking installation. First, there’s the timber itself. Certain woods are much easier to work with, while others require more care and special construction — and this will affect the overall timeline. That said, there are three phases of each deck installation project: 

PHASE ONE: Planning, Design and Layout

PHASE TWO: Foundation, Posts and Framing

PHASE THREE: Decking, Railing and Stairs

Phase one will invariably take the most time, as designing your deck, getting permits, finishing your council applications and other preparation tasks tend to take awhile. That said, once your design gets prepared and approved, the process will be quick and smooth. 

At Urban Arch Building, we take great pains to ensure that your job is completed to the highest standards and with minimal interruption to your day-to-day routine and lifestyle. Want to learn more? Reach out to one of our experts for more information or for a free quote.

Frequently Asked Questions About Jarrah Decking In Sydney

How do you maintain a jarrah timber deck?

If you want your jarrah deck to maintain its colour and texture, you’ll need to put in some work to maintain your deck. However, the amount of maintenance that your deck needs will depend on many factors, including the weather, the amount of foot traffic, and the number of spills or other issues you encounter.

In any case, it’s recommended that you clean your deck at least once or twice a year using a product like oxalic acid, although you can also hire professionals to do this maintenance for you if you’d rather keep your weekends free.

Is jarrah a hardwood or a softwood?

Jarrah is a hardwood, scoring 8.5 on the Janka rating (anything above a score of 8 is considered to be a hardwood). However, unlike harder alternatives like ironbark, jarrah is still soft enough to easily work with sharp tools.

What is jarrah wood used for?

Known for its versatility and durability, jarrah is an ideal wood for a variety of uses, including:

  • House framing
  • Flooring
  • Linings
  • Fencing
  • Decking
  • Furniture
  • Stairs
  • Balustrades

Is jarrah a better timber than spotted gum?

This comes down to preference more than the inherent attributes of each timber. Before making your choice, be sure to consider the location of your new deck, your preferred level of maintenance, the appearance of your decking, and qualities of durability and longevity.

Will a jarrah deck retain its colour?

In short no – but there’s more to this question. Jarrah’s appearance ranges from light reds to deep browns, though exposure to sunlight can transform decking boards into a rich, elegant burgundy shade. However, if left untreated, jarrah timber can turn to a pebbly grey. This is preferred by some Sydney homeowners who want their deck to mature as it ages, although the close grain of jarrah means initial colours are held for longer.

If you’d prefer to maintain the red/brown/burgundy colour palette, you’ll need to look after your new deck with regular oiling and sealing to prevent fading.
