Below is a list of what we offer:

Building Installations

With the vehicles, manpower, and management skills to organise and install portable buildings, we’re able to facilitate small to large-scale projects for Western Australia’s mining, civil, and construction industries. This includes the project management of smaller projects such as building movements.

We offer tailored building maintenance systems that will meet the exact needs of your project. Whether you need a team of expert carpenters, licensed plumbers, or highly-trained machine operators, you’ve just found Onslow’s best building maintenance providers. This includes specialist commercial property maintenance in Pilbara.

Drainage and Plumbing

When it comes to commercial plumbing and drainage, we have 30 years of experience doing the dirty work. We house a skilled team of licensed plumbers that can identify and fix problems in a single visit. Furthermore, we implement custom plumbing maintenance outcomes that will eliminate the risk of blocked drains and burst pipes, among a world of other potential issues.


In addition to our building and maintenance services, Onslow Contracting has years of experience in the carpentry or construction sheds, offices, workshops, and building installations. Our team of carpenters will work on your site, supplying you with our company’s rich history of craftsmanship.
