Composite Decking Central Coast
We all moved to the Central Coast for its beaches, sun, and close connection to nature. However, the Australian sun and saline coastal air may be brutal on traditional outdoor structures. Timber warps and splits and requires regular oiling, taking away your weekends that could be spent soaking up the sun in Terrigal or enjoying the family vibe in Gosford. That’s where we come in.
GTG Constructions specialises in composite decking Central Coast that customers trust for long-term use, design, and hassle-free installation.
The time has come to switch to a solution that truly works if you are tired of sanding, oiling, and painting your old timber deck.
Common Decking Problems in the Central Coast
You might be wondering, “Is composite for decking really better than timber?” In our coastal climate, the answer is a yes if you are facing the following problems:
- Salt Air Corrosion: Constant exposure to salty air gradually rusts and deteriorates steel fasteners (screws, nails, clips).
- Regular Maintenance: Timber decks require high maintenance, including frequent cleaning, oiling, and sealing (sometimes every 6 to 12 months).
- UV and Heat Deterioration: Australian sun and high temperatures cause wood to rapidly fade, crack, and warp.
- Moisture and Rot: The coastal humidity, heavy rains, and dew lead to moisture absorption in timber, creating perfect conditions for wood rot, mould, and mildew.
- Pest Infestation: Traditional hardwood decks are highly vulnerable to termites and other wood-boring insects, which usually require costly replacement.
- Water Damage: Is the money you invested warping, rotting, or turning grey due to the harsh UV rays and sea air?
Our Composite Decking Services
We design spacious composite decks perfect for BBQs, dining areas, and entertaining guests. Our composite decking installers provide a clean finish that looks like natural timber but acts as a barrier against the elements.
We use lightweight yet strong composite materials and subframes designed to handle elevation and load, providing safety and style for your second-storey spaces.
There is no better material than composite decking around pool. Timber splinters can be harmful to bare feet, and chlorine or saltwater can turn the wood grey in months. Our composite pool decking solutions (e.g., white composite decking) are designed to be both cooler underfoot and slip resistant for areas with high levels of sun exposure.
Do you have an old timber deck that is no longer safe or appealing? We specialise in composite decking replacement. If the existing subframe is intact, we can remove the rotten timber and refurbish it with new composite boards, saving you thousands of dollars.
Composite decks are durable, but if a heavy object breaks a board, or if you notice any boards lifting or fasteners failing, we are here to help with composite deck repair Central Coast. The major advantage of the hidden fastener systems we use is that we can replace the broken boards or repair specific parts without disturbing the whole structure.
We work with you to incorporate integrated design features directly into your new composite deck. We enhance your outdoor space with features like built-in bench seating, integrated LED lighting, split-level decks, or custom planter boxes.

Frequently Asked Questions
Does composite decking get hot?
Composite decking can get warmer than timber in direct sunlight. We use high-quality boards with cool deck technology. We generally recommend white composite decking in full sun since it reflects the most heat.
Is composite decking expensive?
The upfront cost of composite decking Central Coast projects is typically more than pressure-treated pine but comparable to high-end hardwoods such as Merbau. However, when you consider the expense of oil, stain, and timber repairs over a ten-year period, composite can be more affordable in the end.
Can you build over my existing concrete patio?
Yes. We can install a low-profile subframe over concrete to give you a timber-look finish without the demolition costs.
How do I clean and maintain my new composite deck?
Composite decks need a simple regular cleaning with mild soap and a soft-bristle brush, a low-pressure wash, or a specific composite deck cleaner to remove stains, surface dirt, dust, or pollen.
Are your composite boards slip-resistant for wet areas?
Yes. Our composite boards are thoroughly tested and have high anti-slip ratings. They are therefore much safer than wood decking, especially near pools and on verandas due to high humidity.
