Our Philosophy

Make it happen

We’re resourceful and reliable. If there’s a better way to do something, we’ll do what it takes to find it.

When we’re thrown curveballs, we’re proudly known for knuckling down, finding workarounds and solving problems to make things happen and keep projects on schedule. No fuss.

Play Fair

Say what you do and do what you say. We’re big on keeping commitments to our clients, and each other.

If we say we’ll do something, we won’t rest until we do. If there’s a problem we take personal responsibility and we put things right. Straight up.

Deliver Strong

The job isn’t over until it’s over. We stay focused, determined and professional at every stage of a project to ensure we get the job done right and never take our foot off the pedal.

We’re committed to finish just as strong as we start. Every time.

Our Values

We do what we say

At CJ Duncan, our word is everything. If we say we’ll do something, that’s precisely what we’ll do. From deadlines to budgets to paying contractors on time, what you hear is what you’ll get.

Built on Quality

Our reputation for delivering quality is everything. That’s why we never compromise or cut corners. We’re detail‑focused and use our market-leading skills to deliver projects to the highest possible level every time. We’re only as good as our last project, so it needs to be great.


We’re like a family

We’ve grown a lot. But we’ve never forgotten our family roots. After 40 years we’re still a tight knit business with a candid, people‑first attitude. From our clients and contractors to our in-house team, our success is built on a foundation of strong, personal relationships and respect.

Big results, low fuss

We make things happen. Maximum effort, minimum fuss. We take pride in our ability to knuckle down and get the job done. “Whatever it takes” has always been the attitude that drives us. If there is a smarter or more effective way to do it, we’ll find it.
