Geelong Coastal Deck Transformation: Composite Decking Case Study

Location: Torquay, Geelong (Surfcoast)
Project Type: Residential deck renovation
Product Used: THQ Signature Series Composite Decking
Challenge: Coastal salt air, weathering, timber rot

The Challenge

A Torquay homeowner had a 12-year-old timber deck facing the Tasman Sea. The salt-laden air had done the expected damage: surface checking, discolouration, soft spots where rot had begun, and boards that moved underfoot. Annual staining wasn't stopping the decay. The entire deck was becoming unsafe.

The homeowner had two choices: spend $3,000–$4,000 replacing the timber boards every five years, or invest in a composite solution that would handle Geelong's coastal exposure.

The Solution

THQ supplied Signature Series composite decking—engineered specifically for coastal Australian climates. No timber rot risk. No salt air degradation. No annual staining or maintenance cycle.

The renovation involved:

• Removal of failing timber decking
• New composite board installation over existing, solid sub-frame
• Matching fascia and trim using THQ composites
• Completion in four days

Before / After

Before: Weathered timber with visible rot, soft boards, discoloured and checked surface, constant maintenance burden.

After: Clean composite decking with consistent colour, solid underfoot, no movement or flex, salt-resistant finish, zero maintenance requirements.

Tradie Notes

Installation was straightforward. Composite decking fastens similarly to timber, but doesn't warp or split during installation. No pre-drilling required for fasteners (unlike timber). The deck was solid immediately—no settling or movement over time. Clean-up was minimal. Geelong builders appreciate that composite doesn't demand the same fiddly, time-consuming finishing work that timber does.

The Result

Two years post-installation, the composite deck looks as new as day one. No fading. No salt staining. No maintenance. No repair calls. The homeowner's actual quote: "It's the best money I've spent on this house. I don't think about the deck anymore—that's how good it is."

Over the next 20 years, this composite deck will outlast three timber replacements and cost a fraction of the maintenance and repairs timber would have demanded.

Why This Matters for Geelong

Coastal Geelong—Torquay, Ocean Grove, Lara, Newtown, Belmont—experiences the same salt-air exposure. Timber is a recurring expense. Composite is a one-time investment that performs for 25 years.
