The Expand Group Story

For more than 25 years, Expand Group has supported WA homes, businesses and remote communities with dependable plumbing, gas and leak detection services. What began as a small family-owned team has grown into a trusted provider known for quality workmanship, technical expertise and a genuine commitment to doing things properly.

Where We Started

Expand Group was built on the belief that strong foundations create long-term results.
With backgrounds in both plumbing and building, we began as a small Perth-based team delivering reliable maintenance work with a focus on safety, compliance and honest service.

Over time, our capabilities expanded into gas fitting, leak detection, construction support and 24/7 emergency work. Today, we provide end-to-end solutions across residential, commercial and industrial settings.

Working Across Perth, Regional WA and Residential Properties

While we proudly service the Perth metro area, our team is also equipped for regional and remote projects. Our work spans both large-scale commercial environments and everyday residential needs, including strata-managed complexes where fast and accurate leak detection is essential.

We’ve delivered work across:

Commercial facilities
Defence and government sites
Industrial operations
Regional towns
Remote communities, including the Cocos (Keeling) Islands
Residential properties and strata-managed buildings

Our systems, training and equipment are designed for metro, regional and residential deployment, ensuring seamless service wherever we’re needed.
