Construction & New Builds in Thirroul
Full construction plumbing from slab to fit-out for residential, commercial and industrial projects.
Thirroul's older homes — many built between the 1920s and 1950s — commonly have original clay sewer pipes that are cracked, offset, or riddled with tree roots. Blocked drains are extremely common here. Renovation work is booming as buyers upgrade period homes, and we handle everything from rough-in to full bathroom fit-out.
Ross Barber Plumbing can discuss custom home builds in Kiama and Shellharbour and commercial construction projects. We coordinate directly with builders and developers about the plumbing scope.
We work across Thirroul regularly and know the local infrastructure well. Whether it is a planned job or an urgent callout, we pick up the phone and we show up.

Common questions about construction & new builds in Thirroul
Answers to the questions we hear most from Thirroul customers.
How early in a new build should I involve a plumber in Thirroul?
As early as possible, ideally at the planning stage. For new builds in Thirroul, involving a plumber from the beginning means drainage layouts and service routes are designed into the project from day one rather than worked around later. We coordinate directly with builders and developers.
Do you handle slab plumbing for new homes in Thirroul?
Yes. Slab plumbing is part of our new build work in Thirroul. We can discuss the under-slab drainage layout before concrete is poured.
