The north Brisbane renovation builder told Az why client experience is his North Star, why trades get paid the day they finish, and why profit still sits above both.
Jack James pays his subcontractors the same day. He moves the tiles for the tiler and cleans up after him.
Ask him what makes a good builder, though, and he does not start with any of that. He starts with profit.
Jack is a director of James Marsden Builders, a renovation and extension business on Brisbane’s northside that he runs with his business partner, Ben. Az sat down with him on the final day of The Professional Builder’s AI and Marketing Summit at The Star Gold Coast in October.
What came out of it is a clear picture of a young business at a turning point. Plenty of work, a strong trade base, and a bottleneck sitting in the office.
How Did Jack James Get Into Building?
Building runs in the family. His dad is a plumber and his two younger brothers are electricians.
Jack was working for builders on school holidays from the age of 14. In 2008, the family’s neighbour was a builder, and at 15 Jack signed on for a school based apprenticeship in grade 11. He stayed with that builder for about six years.
From there he moved to a custom builder on Brisbane’s northside, then into commercial carpentry. One of those jobs was Mr Percival’s at Howard Smith Wharves, under the Story Bridge. Jack worked on the deck, built from old timber beams that were taken away, recycled and screwed back down. His name is written behind the VJ lining on the soffits.
He and his wife then spent two years in Canada, where he kept working as a carpenter through winters of minus 17 degrees and dark by 4pm. His biggest takeaway, he said, was simple: “I am so grateful for where we live.”
Back in Brisbane, he moved from carpentry contracting into running a building company. He is open about the fact that he does not yet hold his own builder licence. The company operates with a nominee while he builds the experience to apply for one himself.
What is a nominee supervisor in Queensland?
In Queensland, a building company holds its own contractor licence, and the QBCC requires that company to nominate a qualified individual as its technical expert. That nominee must be a director, secretary or employee of the company and hold a contractor or nominee supervisor licence in the same class. The nominee is responsible for making sure the company’s building work is properly supervised and meets the relevant standards and codes. Source: QBCC
Why Target the $250,000 to $1 Million Renovation Market?
Jack said there are plenty of builders in Brisbane working on renovations of $1 million and up. James Marsden Builders has deliberately niched below that, focusing on jobs between about $250,000 and $1 million.
Most of his clients have the same story. They love where they live, the kids are settled at school, and buying a bigger home in the same suburb is out of reach. Moving means going a long way out to get more space.
So the brief is usually modest. An extra bedroom. An ensuite. A bigger kitchen and a deck.
The business is also willing to stage work to fit a budget. Jack gave the example of sheeting an ensuite so the client can come back and fit it out later, rather than walking away from a job that cannot be done all at once.
Why Does He Pay Subcontractors the Same Day?
Most conversations about managing subcontractors start with contracts and payment terms. Jack starts somewhere else.
The business pays trades on the day. He said they may move to seven days at some point to help cash flow, but he did not feel that was something they had earned yet.
“We didn’t deserve that until we showed our worth by paying the same day for everyone.”
The same thinking runs through how he works on site. Making sure the job is ready. Moving materials for the next trade. Cleaning up after them. “He’s doing so much for me, like I feel like I’ve got to do so much back,” he said of his tiler.
Az put it in Queensland terms. Builders and subbies come from different businesses, the same way State of Origin players come from different clubs. Once they are on the job, they are one team.
Jack’s idea of success follows the same line. An invite to his plumber’s daughter’s 21st. A day at the footy with a supplier. A third project with the same architect and client. “It’s not really like a monetary thing,” he said.
What Happens When a Small Builder Has More Work Than It Can Price?
The business leaned hard into relationships with local architects and drafters. Jack said that has worked. The problem now is keeping up with estimating.
Right now, pricing lives in his and Ben’s heads. They are onboarding a virtual assistant and building a system so someone else can take a set of plans to about 80 per cent of a price, with the partners reviewing the last 20 per cent.
The aim is not to step back from site. It is the opposite. “We’re kind of just trying to hire ourselves out of the office,” Jack said. The team is small: the two partners, one apprentice and a couple of virtual assistants.
Az made the point that there is more than one way of running a building business. Some owners step back into a systems role. Others are craftsmen who do their best work on the tools. “There’s no right or wrong,” he said. What matters is knowing which one you are and building the rest of the business around it.
What Did He Take From the Summit?
About 18 months ago, Jack and Ben were running three projects at once, working Sundays and doing the paperwork at night. Jack was listening to our podcast when The Professional Builder founder Marti Amos came on, and they emailed the coaching company straight after.
He noted that despite how much The Professional Builder markets, he had never come across it before that episode. For him, it was a reminder that your marketing may reach fewer people than you think.
What he values most is the room. A group chat with other member builders lets him ask a question on a Sunday afternoon and get an answer from someone who has already solved it. The biggest lesson from events like the summit, he said, is realising “you’re not the only one making mistakes.”
The summit also helped him think through a longer term plan to move his family to the Sunshine Coast, and how that might work for the business.
Why Does Profit Sit Above Client Experience?
Client experience is the business’s North Star, Jack said. But when Az asked what makes a good builder, he put profitability above it, because without profit none of the rest is funded.
Same day payments need money in the bank. So do the building choices he will not compromise on. Jack said the business does not use liquid waterproofing membranes internally, using waterproof board systems instead. It costs more, and it only works if the jobs are profitable.
He was clear that profit is not about new utes. It is “profitable so that we can have a business that is sustainable” and can keep doing good work for everyone involved.
He is not the first guest to land there. It is a theme that keeps coming up on the podcast, and it is why good builders still lose money when the business behind the build is not set up to carry them. Paying trades fast is a choice that depends on healthy cash flow for builders, not just good intentions.
That is the useful part of Jack’s answer. Generosity to trades and clients is not separate from the numbers. It is paid for by them.

The Good Builder Take
Same day payment is easy to admire and hard to sustain. What stands out in Jack’s story is that he links it directly to margin rather than treating it as goodwill.
The estimating bottleneck is the part many small renovation builders will recognise. Winning work through relationships is one stage. Pricing it without the owners staying up at night is the next.
Frequently Asked Questions
Jack James is a director of James Marsden Builders, a renovation and extension builder on Brisbane’s northside, which he runs with business partner Ben. He started a school based carpentry apprenticeship at 15.
Jack told the podcast the business targets renovations and extensions between about $250,000 and $1 million, below the $1 million plus market where he said many Brisbane builders compete.
He said he wanted to show the business’s worth to its trades before asking for longer terms, and that paying quickly builds a sense of one team on site. He said seven day terms may come later to help cash flow.
Profitability. He said client experience is the priority, but profit is what funds it, along with same day trade payments and the more expensive building methods the business chooses to use.
The QBCC requires a licensed building company to nominate a qualified director, secretary or employee who holds a contractor or nominee supervisor licence in the same class. That person is responsible for making sure the company’s work is properly supervised and meets standards.
