How to Know If You Can Trust a Subbie or Employee

"Good bloke" is not the same as "can be trusted on my job"

Ask most builders if they trust their crew and you get a gut answer. "Yeah, Dave's solid." "The new fella, jury's still out." The trouble is that gut read is almost always built on whether you like the person, whether they are easy to have a beer with, whether they show up. None of that tells you the thing you actually need to know, which is: can I leave this person on a custom build and trust that my margin, my program, and my reputation are safe in their hands.

A bloke can be great company and still cost you money on every job. He can be a hard worker and still hide a mistake until it becomes a defect. He can be loyal and still have no eye for the finish that your clients are paying premium money for. Likeability and trustworthiness are different things, and conflating them is how builders end up carrying dead weight for years.

This sits under the bigger piece on building a team so you stop being the bottleneck, because you cannot hand anything over to someone you have not honestly assessed. Trust is the foundation the whole team build stands on.

The 4 things trust actually means on a build

When I work through this with a builder, I break trust into 4 plain questions. Vague feelings turn into something you can actually judge.

1. Can they be left alone without the quality dropping

This is the big one. If you have to stand over someone for the work to be right, you have not got an asset, you have got a task you are supervising. The test is simple: when you are off site for a day, does the work come up to your standard, or do you spend the next morning fixing and re-doing. A person you can trust holds the line on quality when nobody is watching, because the standard lives in them, not just in you.

2. Do they bring you bad news early

Every job has problems. The set-out is out, the slab is not level, the window schedule is wrong. What separates a trustworthy person from a liability is whether they tell you the moment they see it, or whether they bury it and hope. Early bad news is cheap to fix. Buried bad news becomes a defect, a callback, or a HOW warranty claim. If someone consistently brings you problems early, even uncomfortable ones, that is gold. If you keep finding out too late, no amount of skill makes up for it.

3. Do they treat the client's house like it matters

On a custom build the client is living their dream through your work, and they are watching. Does this person keep the site tidy, talk to the client with respect, wipe their boots, own a stuff-up instead of hiding it. Or do they leave rubbish everywhere, complain in front of the owner, and treat a $1.2 million home like a knockabout job. The crew's behaviour is your brand whether you manage it or not.

4. Do they make you money or cost you money

Strip the emotion out and look at the maths. Some people are fast, clean, and right the first time, so they earn their keep many times over. Others are slow, need re-work, cause delays that flow through your whole program, and quietly turn a profitable job into a break-even one. You do not need a spreadsheet for every nail, but you do need an honest sense of who lifts the job and who drags it.

Trust is earned in small things first

You do not hand someone the keys to a whole build on day 1. You give a small thing, watch how they handle it, and let trust compound. Did they finish what they said they would. Did they flag the problem. Did they leave it clean. Each kept promise earns a bit more rope. Each broken one tells you to keep them on a shorter leash, or move them on.

The mistake builders make is going all-or-nothing. Either they trust someone completely on a hunch and get burned, or they trust nobody and stay the bottleneck forever. The real path is in the middle: deliberately give a bit, watch, adjust. That is also how you decide who is ready for more responsibility when it is time to stop being the bottleneck in your building business.

The same lens works for subbies and employees

People ask if this is different for subbies versus employees. The core questions are identical. Can they be left alone, do they flag problems early, do they respect the client and the home, do they make or cost you money. The difference is your leverage. With an employee you can train and coach over time. With a subbie you are mostly choosing who you let onto your jobs in the first place, and how you set expectations before they start. The judgement is the same, the response is different. I go deeper on the subbie side in managing subcontractors: holding standards and timelines.

What to do when the answer is no

Sometimes you run someone through these 4 questions and the honest answer is that you cannot trust them with what matters. That does not always mean sacking them. It might mean they are great on labour but should never run a job. It might mean they need closer supervision on finishes but are fine on rough-in. Knowing exactly where someone can and cannot be trusted lets you use them well instead of either over-trusting them or carrying them as dead weight.

But sometimes the answer is that the person is costing you more than they bring, in money, in stress, or in damage to your name, and the kindest and smartest thing is to move them on. Builders hang onto bad fits far too long out of loyalty or fear of the gap. The gap is almost always cheaper than the drag.
