Decks provide an outdoor living space for our homes; they are spaces where we can lounge about in beautiful weather and enjoy spending time socialising with family and friends. However, to make the most of these moments, it’s essential your deck is clean and nicely maintained.

Exposure to the great outdoors and regular general wear and tear means your deck needs to be maintained and cared for. As well as day-to-day cleaning and maintenance, the following deck maintenance tips and actions should be carried out at least once a year. 

Washing and cleaning your deck

A thorough yearly clean of your deck is critical to the upkeep of your outdoor space. Letting leaves and dirt sit on your deck for long periods of time can lead to discolouration and encourage mould and rotting of timber decks. 

As a starting point, sweep your deck to remove obvious debris and dirt from the surface. Use a soft-bristled brush or broom, and a deck wash or cleaning solution to scrub your deck’s surface – it’s important to choose one that’s appropriate for your deck. There is specialised timber deck cleaner for wood decks, and products tailored specifically for composite decks. Using a deck cleaner is crucial, as it will not only help wash away muck and build up but will also kill mould and mildew.

If you still feel your deck needs a more thorough clean, an oxygen bleach may be appropriate. Unlike chlorine bleach, these won’t remove the natural colour from the timber or composite deck and won’t damage your plants or garden.

Deck repair and general maintenance

Once you’ve cleaned your deck, it will be easy to inspect it and identify any problem areas. Check for loose, split or rotten boards. It’s essential you repair these, fix them back in place, or replace them with new ones. If not, this can lead to further deterioration of the deck, as the boards may twist and warp.

As timber ages, it can swell and shrink, causing nails and screws to rise above its surface. If this is the case, simply grab a hammer and nail punch or screwdriver and work them back into place, slightly below the deck’s surface. If possible, replace any rusty screws or nails, as these can lead to discolouration of the deck and may cause the timber to become loose.

Sanding and sealing your deck

Before sealing and after cleaning, let your deck dry then sand it to remove any irregularities and splinters. This allows the sealant to properly sink into and be absorbed by the timber, protecting it. Often when the surface isn’t sanded back, the oil will not absorb evenly and it will lead to marks and uneven colouring.

It’s important your deck is sealed to stop it from cracking, splitting, and warping; coating your decking boards with a sealer will also help with your deck waterproofing. The appropriate deck sealer, deck stain or decking oil for your deck will depend on the type of material or decking product you’ve opted for; speak to your decking supplier to find the right sealer to use.

As a rule,  protecting with a penetrating sealer will deliver the best results. Deck paint and sealers that remain on the surface tend to fade and peel, quickly making your deck look worn.

It’s also worth remembering that most composite decks don’t require a sealant or staining – so if you’re considering replacing decking boards or building a deck, this might be the best option.

A final note

Taking the time to wash and clean, repair, and sand and seal your deck annually will quickly have it looking like new, making it a great space for you to spend time year-round and protecting your investment for the term.

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!
