How much does it cost to build a private jetty in NSW?
Jetty costs depend on length, water depth, access, materials, engineering requirements, and approvals.
Do I need council approval to build a jetty or pontoon?
Yes — almost always.Approvals may involve:
- Local council
- NSW Maritime
- Fisheries
- Environmental authorities
We guide clients through the approvals process and work alongside planners and engineers to ensure compliance.
How long does jetty construction take?
Once approvals are in place, most residential builds take:
1–6 weeks, depending on scope and weather.
Marine construction is weather and tide dependent. Wind and swell can delay works, but safety always comes first. Clients receive clear updates throughout the build.
What is the best material for a jetty?
It depends on your priorities and environment. Common options include:
- Hardwood timber (durable and classic)
- FRP / composite decking (low maintenance)
- Aluminium components (lightweight and corrosion resistant)
- Steel piles with protective sleeves
We recommend materials based on longevity, exposure, and maintenance expectations.
How long should a well-built jetty last?
A professionally built jetty using quality materials should last 20–40+ years with proper maintenance.
Can an old jetty be repaired instead of replaced?
Sometimes. We assess:
- Structural integrity
- Pile condition
- Decking lifespan
- Compliance with current standards
If repairs are viable, we’ll recommend them. If replacement is safer or more economical long-term, we’ll be honest about that too.
What maintenance does a jetty require?
Regular maintenance extends lifespan significantly. Typical maintenance includes:
- Hardware checks
- Timber inspections
- Cleaning marine growth
- Pile condition monitoring
We often recommend inspections every 6 months
What happens if bad weather hits during construction?
Marine works stop when conditions are unsafe. Safety of crew, vessels, and your property is always the priority. Delays due to weather are normal in marine construction and are planned for in scheduling.
Why do marine projects cost more than land construction?
Marine construction involves:
- Barges and vessels
- Specialised crews
- Tidal planning
- Corrosion-resistant materials
- Environmental compliance
- Complex logistics
It’s a specialised field requiring expertise and proper equipment.
Do you handle design and engineering?
Yes. We work with qualified engineers and designers to ensure:
- Structural compliance
- Approval readiness
- Long-term durability
Clients receive a complete, professional solution.
Can you work on difficult access properties?
Yes — this is common in waterfront construction. We regularly work on:
- Limited land access sites
- Steep waterfront blocks
- Tight urban waterways
- Properties only accessible by barge
What makes a quality jetty builder different from a cheap one?
Key differences include:
- Proper engineering
- Marine-grade materials
- Skilled marine crews
- Compliance knowledge
- Longevity-focused construction
Cheap builds often skip these — leading to failures and higher lifetime costs.
What types of projects do you specialise in?
We specialise in waterfront construction, including jetties, pontoons, slipways, seawalls, boat cradles, boatsheds, mooring infrastructure, vessel salvage, and marine maintenance. We also provide barge and machinery hire.
How do I get started?
The first step is a site discussion or inspection. We look at:
- Site conditions
- Water depth
- Access
- Your goals and budget
Then we provide clear advice on next steps.
Where do you operate?
Our team is based in Sydney and services clients across the east coast of Australia.
Can we talk to previous clients of yours?
Yes, if you would like to talk to some of our past clients to get an understanding of what it is like to work with N.G.D, we can arrange a phone call.
Can we see some of your previous work?
Yes, no problem. If it would make you feel more comfortable, we can take you to few of our past sites.
Do you have insurance?
Yes, we have all necessary insurances to undertake all projects.
A copy of these current insurances will be send over with your quote.
