Summer in Forster doesn’t muck around. The heat stings, humidity hangs in the air, and the storms can roll in fast. All that weather can really do a number on outdoor areas, especially decks. Whether yours is brand new or has been there for years, it’s smart to keep an eye on how the summer season affects it.
We often see common timber problems pop up around this time of year. Those minor issues can turn into real safety risks if they’re left too long. Having a deck builder in Forster give your setup a look over before things heat up can take a bit of worry off your plate. Here’s a rundown of what to watch out for.
Deck Timber That Cops It in the Humid Weather
Dry timber is one thing, but when humidity soaks into a deck, it starts to move. In coastal towns like Forster, it doesn’t take long before deck boards swell, split, or warp from constant exposure to muggy air and sudden downpours.
- Swelling boards usually raise around the nails or screws, making the surface uneven
- Soft spots can form where water sits too long, especially in shaded areas
- Warped sections make the timber curve or lift, which turns your deck into a trip hazard
A big part of avoiding this comes down to choosing durable hardwood and sealing it up properly. We use high-quality hardwoods selected for the local climate, which can reduce the risk of excessive movement and damage. But even solid timber can start to go off if it’s not checked regularly. We pay close attention to corners and joins, as those spots tend to trap moisture the longest.
Mould and Mildew Are More Than Just a Nuisance
Sticky air is great for mould, and unfortunately, summer in Forster brings a lot of it. When decks aren’t drying out properly between storms, mould and mildew creep in, often without being noticed until it’s right in the way.
- Mould tends to show up in patches that are black, green, or grey, often near walls or under furniture
- You’ll usually notice it by the smell before it’s seen
- Decks in shaded areas can stay damp all day, giving mould and mildew the constant moisture they love
Slippery patches on timber create more than just a mess. When mould settles into the grain of the deck boards, it begins to break down the surface. That makes bare feet uncomfortable and weakens the timber underfoot. It’s never just about looks, mould left alone can spread quickly across a whole deck.
Fasteners and Joists That Start to Shift
Decks move a bit naturally with the weather, but when temperatures rise and fall quickly, the fasteners holding everything together begin to loosen. Add in humidity, and even well-installed boards can start to squeak or shift.
- Nails pop up slightly, leaving sharp edges that catch bare feet
- Screws twist or snap if boards swell too much
- Joists creak or sag under pressure, which can lead to bounce or wobble
One of the biggest concerns here is safety. Even small shifts in the deck’s structure can make gaps bigger and supports weaker. If a deck feels springy or noisy when walked on, that’s usually a sign something underneath isn’t right. Getting onto those signs early makes any adjustments much easier.
Poor Drainage Means Big Trouble
In places like Forster, summer storms can dump a ton of rain in a very short time. If your deck isn’t built with proper runoff in mind, that water has nowhere to go. It soaks in, sits in low spots, and slowly breaks down the timber, layer by layer.
- Water pooling around or under the deck usually leads to rot
- Signs include a musty smell, soft wood, or discolouration
- Built-up debris in drainage gaps can block runoff and make the issue worse
This is one of the issues we will often check during the warmer months. We can assess your drainage and recommend or install solutions that suit your property, including modifying slopes or adding proper gap spacing during construction. We know local weather can swing between dry heat and heavy rain pretty quickly, so we keep an eye on slope, drainage holes, and any areas where leaves or dirt tend to collect.
Sun Damage That Dulls and Cracks the Surface
The Aussie sun doesn’t hold anything back, especially in the lead-up to late January. UV rays hit hard, baking the surface of decking and pulling moisture out of the timber. That leads to new cracks and surface wear, even on decks that felt solid just a few weeks earlier.
- Faded boards lose their colour and look tired from daily exposure
- Hairline cracks start up across the boards and widen with more heat
- Timber turns brittle or rough, making it uncomfortable to walk on or sit against
When we notice this, it’s often a matter of poor or worn-off sealing. If the deck hasn’t been re-coated in some time, the sun breaks down that protective layer. We recommend periodic resealing as part of regular deck maintenance, which helps guard against UV damage and prolong timber life. Once the surface is exposed, it doesn’t take long for damage to follow. A good check of the surface condition before a heatwave rolls in can help keep summer use comfortable and safe.
Protect Your Deck with Pro Expertise
Staying ahead of the summer weather is much easier than fixing problems after they’ve kicked off. A few small checks while the season is still ramping up can prevent a whole lot of bother later. We always say it’s better to catch warped timber or soft spots early, before they affect how your deck feels underfoot.
