Deck Builder WollongongTimber, Composite & Patio specialists.

Deck pricing in Wollongong typically ranges from $600 to $1,500+ per square metre depending on the material, design complexity, and site conditions. A basic treated pine deck starts from around $600–$800 per sqm, while premium Australian hardwoods like spotted gum or blackbutt range from $900–$1,200 per sqm. Composite decking from brands like Trex or ModWood sits in a similar range to hardwood, with reduced long-term maintenance costs. A typical 30–40 sqm deck in Wollongong can cost anywhere from $18,000 to $55,000+ fully installed. The best way to get an accurate figure is a free on-site quote — prices vary significantly based on access, height, and subframe requirements.

In many cases, no. Under the NSW Housing Code, single-storey decks up to a certain area and height can be built as Complying Development — a faster, cheaper approval pathway that doesn't require a full DA. The specific rules depend on your zone, lot size, proximity to property boundaries, and heritage overlays. Wollongong City Council has some specific requirements, particularly for properties in flood zones, heritage areas, or near the escarpment. Graham's team will advise you on the compliance pathway for your property at the initial site visit. For projects that do require a DA, we can recommend local certifiers and drafting services we've worked with successfully.

Build timelines depend on the size and complexity of the project. A standard 25–40 sqm residential deck typically takes 3 to 7 business days on site. Larger projects with pergolas, stairs, or complex framing may take up to 2 weeks. Lead times from quote to build commencement in Wollongong currently range from 2 to 6 weeks depending on the season — summer is the busiest period. We recommend booking your site visit as early as possible if you want your deck ready for summer entertaining. We provide a confirmed build commencement date when your deposit is received.

Wollongong's proximity to the coast means salt air, UV exposure, and occasional high humidity are all factors. The best performing materials in local conditions are: (1) Dense Australian hardwoods like spotted gum and blackbutt, which have natural oils and high Janka hardness ratings that resist weathering, and (2) Premium composite decking like Trex or Futurewood, which is impervious to moisture and salt air and won't rot or splinter. Treated pine is a valid budget option but requires more regular maintenance and is less resistant to coastal conditions over time. Graham will walk you through the pros and cons of each option at your free site visit based on your specific location and exposure.

Wollongong Decking Co sources materials from trusted local and national suppliers to keep quality high and lead times short. For timber, we work with established hardwood merchants across the Illawarra and source certified timber through reputable NSW timber merchants. For composite decking, we source directly through authorised distributors of Trex, ModWood, and Futurewood — all products available through major trade suppliers including Bowens and specialist composite decking distributors. Using Australian-made or Australian-distributed products where possible is important to us, and it means we can provide proper manufacturer warranties and documentation on every job.

Timber decks in Wollongong's coastal environment benefit from an annual maintenance routine. Clean the deck with a low-pressure hose and mild deck cleaner; allow to dry for 2–3 days; sand back any raised grain lightly; apply a quality penetrating timber oil or sealant using a roller or brush, working with the grain. For hardwoods, products like Intergrain Ultradeck, Cutek Extreme, or Feast Watson are widely available at local Wollongong hardware stores including Bunnings Wollongong, BBC Hardware Dapto, and trade suppliers. We provide every new deck customer with a written maintenance guide specific to their timber species.

Yes, and often that's the most cost-effective option. The critical factor is the condition of the subframe — bearers, joists, posts, and footings. If these are structurally sound, worn or damaged decking boards can be replaced at a fraction of the cost of a full rebuild. If the subframe has significant rot, termite damage, or structural failure, a full rebuild will deliver better long-term value. Graham will inspect your existing structure at the free site visit and give you an honest assessment of both options with pricing for each.

For many Wollongong homeowners, yes — composite decking delivers strong long-term value despite a slightly higher upfront cost. The main advantages are: zero oiling or staining required, no splintering (excellent for families and barefoot living), better resistance to coastal UV and moisture, and 10–25 year manufacturer warranties. When you factor in the cost of timber maintenance products and time over a 10–15 year period, the total lifetime cost of composite decking is often comparable to or lower than premium hardwood. Composite is particularly popular in Wollongong for pool surrounds, north-facing sun-exposed decks, and properties right on the beachfront where UV and salt air are most intense.

Under NSW Building Code and Australian Standards, decks that are 1 metre or more above ground level require a compliant balustrade at a minimum height of 1 metre. For decks above 4 metres, the balustrade height requirement increases to 1.2 metres. Balustrades must also meet opening size restrictions to prevent young children from falling through or getting stuck. These are non-negotiable safety requirements — not optional upgrades. Any builder in Wollongong who offers to skip balustrades to save costs on a deck above 1 metre is putting you at legal and safety risk. Wollongong Decking Co always builds to code and will flag any compliance issues with your existing structure during renovation work.

Check the builder holds a current NSW contractor licence via the Service NSW licence checker (required for decks exceeding $5,000 in value). Ensure they carry current public liability insurance and ask for a certificate of currency. Never proceed on a verbal quote — a reputable builder provides a detailed, itemised written quote. Look at Google reviews, Houzz, and ask for local references in Wollongong. A builder who has worked extensively in the Illawarra understands local council requirements, soil and terrain conditions, and the specific demands of coastal construction. Graham is happy to provide references from previous Wollongong clients and answer any questions about our licensing and insurance credentials before you commit.
