North West Occupational Hygiene --- PILBARA - KIMBERLEY - GASCOYNE

About Us



NWOH opened its doors for business in January 2014 when the resource sector was showing signs of a slow down. We accepted the risk and developed a low cost business model that we believed was suited to the new economic climate.

One of our biggest advantages is being based where our customers operate. We can respond on demand in most cases because we're not limited by flight schedules. Many of our clients have taken advantage of this flexibility by scheduling our work around operational variables often with no extra associated cost.

Since January 2014 we have supplied services to a range of clients in the resource, government and commercial sectors. We have enjoyed ongoing work with many clients which is a sure sign we are on the right track.

Kullarri Building

NWOH have been working with Kullarri Building consistently since November 2014.
Alan is an honest hard working professional who has added a great deal of value to our business.
They continue to work with us under an agreement that gives us the flexibility to use them as we need them.
NWOH have contributed to our success and expansion over the past 12 months and I consider them a great investment.

Viking SeaTech

We asked NWOH to quote on a project because we want to support other local businesses and they got the job because of price and what they promised to deliver.
I was impressed with Alan’s professional approach and the reports he provided were easy to read. The thing we liked the most about the reports were the graphics.
We could easily see where the problems were from the illustrations which made it easy for me to justify corrective actions.
I wouldn’t hesitate to recommend NWOH or use them again in future.
