Decks are more than just a functional addition to any house where you can spend summer afternoons with friends and family; they are also a great way to increase the value of your home.

Once the decision has been made to install a deck for your home or commercial property, there are a few choices available regarding the material you use to build your deck. As technology advances, more and more decking options, especially planet-friendly alternatives, become available to the Australian market; composite decking, timber decking are all great contenders.

Composite decking is a combination of recycled wood and plastic, making it non-toxic, durable, and water resistant. The combination of wood and plastic gives you the best of both worlds – the durability of plastic and the aesthetic appeal of timber – to create the highest quality decking product that is both functional and long-lasting.

Undeniable advantages of composite

As with anything, there are both advantages and disadvantages to composite decking. Using composite material often costs more up front, yet long term costs are lower than with timber, as maintenance and installation costs can be far less than other decking options.

Compared to wood, waterproof composite stands up to the elements much better, needing little more than regular cleaning to keep in tip-top condition. With a wood deck, splinters are a concern, as is making sure it is regularly treated. A composite deck eliminates both of those concerns, along with the often-unavoidable warping of wood planks.

As with any outdoor installation, termites and elemental damages are something to consider – with composite decking; you can say goodbye to these issues; composite decking is designed to combat the main issues that timbers are susceptible to. In other words, you can “get the beautiful timber look, without the timber hassle”.

Installation process and considerations

After you decide if you will be installing the deck or if you will be hiring a deck installer or contractor, it’s time to get building.

The elements involved in a deck building project can be broken down into five easy steps. These include planning, measuring, framing, securing and laying.

1.      Plan & Design

The first step to building any deck is to figure out how much material is needed, where the deck is going, and gathering all tools and materials required. Something to consider is to choose darker composite material will retain heat and get hotter; if you like to be barefoot or if your deck will be under direct sunlight, choosing a lighter colour or mixture of colours will make the deck more enjoyable.

2.      Measure & Pour

Measure the area where the deck will be and begin setting a strong foundation. Use a post hole digger to dig the holes needed for the deck footings. Pour concrete in and allow it to cure for at least 24 hours.

3.      Frame

While waiting, install the ledger board to the house to secure the deck to the house. Once the concrete has cured, attach post anchors the stirrups to the deck footings. Alternatively, you can cast them into concrete as you go. The KlevaKlip adjustable bearer supports are perfect for fine-tuning and make the deck perfectly level once the concrete has cured. Then attach posts or bearers directly to the stirrups. Frame your deck out, adding concrete footings, depending on the size of the deck.

On both the ledger board and end beam, install joist hangers at the desired intervals, approximately every 15.24 cm. Cut the joist boards to fit and install them by seating the boards into the hangers and securing with nails. Ensure you are plumbing often, checking the level and adjusting as necessary.

4.      Secure

Ensure that your deck is levelled; this should be levelled from the beginning by using consistent sizes for your subframes. Using a chalk line can help you find the high spots to grind down.

Seal any joints or areas at risk of high moisture with a compound. Using joist protection like GTape over the top edge of the joists can also help protect the deck from long term rot – choose a dark tape colour to avoid drawing attention away from your decking.

5.      Lay

Once your foundation is in place and stable, it’s time to lay down the deck boards. Use the applicable manufactures proprietary fixing system. Different brands of the composite have different fixing methods. From top fixing screws that ‘disappear’ through the top surface, to ‘biscuit type’ or strip click-in strips both of which produce secret or concealed fixing.

Butt joints are best avoided with composite decking because of the significant thermal movement that occurs daily. Use full-length boards with feature or breaker boards to ‘hide’ the necessary expansion joints. The best time to set this up correctly is in the planning stage where you can, if possible, design the deck to be the same size as the available boards. Helping save a massive amount of time and material wastage and in turn, save money.

Optional: Installing Add-ons

The last step is to add deck balustrades, lighting or stairs. Start balustrade posts 6 centimetres away from the house to prevent moisture build-up.

I had no idea where to start when it came to getting decking installed. I was so pleased when I found Decking Perth because they did all the tricky stuff for me - all I had to do was tell them what I was after and what colour and they did the rest. The contractor I ended up choosing to do the instal was fantastic. Couldn't be happier with my new deck! So thank you!

Decking Perth provide great advice for novice deck buyers by showing you a wide range of products underpinned by knowledge and a conduit to deck builders. A couple of days after we visited Decking Perth one of their preferred contractors provided a very competitive quotation and we engaged AllStyle Carpentry. Decking Perth supplied all materials as they are a One Stop Shop for the contractor. The Modwood Xtteme deck looks fantastic and we could not be happier with it. Thank you Decking Perth as your business supported our thinking and your advice saw the planning come together and we now have a lovely deck.Phill Cribb

Could not recommend Deck Perth more. I had a small area at the front of my house which needed Composite decking supplied and installed. Visited their shop for ideas, then they organised a contractor to attend for a quote to install. All done within 2.5 weeks and over the moon with the end result at a reasonable price, thanks again

I contacted Decking Perth regarding an extension to our current Trex Deck. They took my details and within 4 hours I had been contacted by 2 decking installers and both had attended and quoted within 3 days. Jamie from Elite Decking had the job completed the following week! Lovely team, quiet, clean and tidy workers, on time and on budget, attention to detail exceptional. You cannot tell the difference between the 5 year old deck and the new extension. Highly recommend Elite Decking and Decking Perth.

We were seeking a good quality decking oil for our garden landscaping and out-door shower project. We found the reviews on-line for Cutek Extreme Clear wood preserver were very good and suited us as it is absorbed by the timber thereby ensuring greater life expectancy and a great grain enhancer. In addition re-coating every 18mths to 2yrs appealed as the timber only requires a high pressure wash and a dry off period before re-coating. No sanding required. We chose a New Bronzetone tinter to deepen and enrich the merbau timber grain for an excellent aesthetic finish. Next Project the pool deck!
