Overview

New Builds

The plumbing in a new build is the part you never see but rely on every single day. Get it right and it just works for decades; get it wrong and it's buried behind walls and slabs, expensive to fix later. JGH Plumbing installs complete plumbing systems for new homes, extensions and granny flats to the highest industry standard.

We handle the full scope — water supply, drainage, stormwater and gas — coordinated to your build's stages so we're there at rough-in and fit-off when you need us, not holding up the trades around us. Over 10 years of work across Sydney and the Illawarra means we install it properly the first time, with compliance documentation where it's required.

  • Full water supply and drainage rough-in
  • Stormwater and sewer connections
  • Gas line installation for new homes

Timing keeps the build movingPlumbing rough-in and fit-off have to land at the right build stages — we plan around your schedule.
Gas needs licensed handsNew gas lines and connections are licensed work that must be done correctly and tested.

FAQs

New Builds — your questions answered

Do you do plumbing for new homes and extensions?
Yes — JGH Plumbing installs complete plumbing for new builds, extensions and granny flats: water supply, drainage, stormwater and gas, through to bathroom, kitchen and laundry fit-off. We've done it across Sydney and the Illawarra for over 10 years.
Can you work in with my builder's schedule?
Yes. New-build plumbing happens in stages — rough-in early, fit-off near the end — so we coordinate with your builder and the other trades to be there at the right time and keep the job moving rather than holding it up.
Is the work compliant and certified?
Yes. We carry out new work to the relevant standards and provide compliance documentation where it's required. Getting it right and certified protects you and the value of the build.
Do you install the gas as well as the water and drainage?
Yes. We're licensed for gas fitting, so we can install new gas lines and connections as part of the build rather than you having to bring in a separate trade.
How much does new-build plumbing cost?
It varies a lot with the size and complexity of the build, the number of bathrooms, and the fixtures you choose. The only accurate way is a proper quote based on your plans — get in touch and we'll work through it with you, with clear pricing and no surprises.
Do you offer a warranty on new-build work?
Yes. Our workmanship is backed by a lifetime workmanship warranty — which matters most for the plumbing you can't see, set into the slab and walls of your new home.
