About us

A four-person crew that fixes what the cockies started

Cockyproof began in 2016 after one Kirribilli handrail job turned into eleven in the same building. Today we work only on harbourside apartment balconies and decks — the access, the salt, the birds and the strata process are all we do.

Our approach

Repair the timber properly, then remove the invitation

Plenty of trades will fill a chewed rail with epoxy and call it done. Six months of harbour sun later, the filler cracks and the birds return to the same soft spot. We do it the slower way: cut back to sound hardwood, splice in matched timber, cap the exposed edge, then finish the surface so water and beaks both find it boring.

Because we live with these buildings, we also plan the boring parts well — lift bookings, noise windows, corridor protection and the paperwork your owners corporation needs before a cent is spent.

The crew

Who turns up at your door

Small team, same faces. You get the mobile number of the carpenter running your job, not a call centre.

Tom Marsden

Licensed builder, founder

Twenty-two years in carpentry, the last nine on balconies. Writes every scope of works himself.

Nadia Kouris

Lead carpenter

Handles splicing and joinery detail. If your rail has a curve in it, Nadia is the one who solves it.

Reuben Dwyer

Metalwork & capping

Folds and fits our alloy caps and stainless mesh. Also runs the workshop in Peakhurst.

Elise Tran

Client & strata liaison

Books checks, chases access approvals and keeps committees and managing agents in the loop.
