Building work runs a lot smoother when everyone keeps talking.
You don’t need to know what every tradie is doing each day, or understand all the building jargon. But you should know how updates will work, when decisions are needed from you, and who to talk to if something doesn't make sense.
How should communication and site visits work?
It helps to sort this out early, before the build gets busy.
Some builders send regular emails. Some use apps or group chats. Others prefer phone calls or site meetings. There is no single right way to do it — the important thing is knowing how you will stay in the loop.
You should also agree on when you can visit the site. That way, you know when you can walk through, see progress for yourself, ask questions, and chat through anything that needs a decision.
It can feel awkward to raise a concern, especially when you are trying to keep things positive.
If something doesn’t look right, doesn’t match what you expected, or hasn’t been explained clearly, ask your builder about it. You don’t need to go in hot. Start with a simple question and work from there.
Even the best-laid plans can hit a bump or two during a build or renovation. Prices can shift, products can become unavailable, and once work is underway, you may spot things that need fixing or clarifying.
The key is to understand what is normal, what needs action, and what should be agreed before anyone carries on.
Why can costs change during a build?
Costs can change for all sorts of reasons. Material prices can go up, something unexpected might turn up once work gets underway, or you may decide to tweak part of the plan.
Some costs may also have started as prime cost sums or provisional sums because the exact cost wasn't known when the contract was prepared. For example, the final cost of an item you've since selected may be different from its prime cost allowance, or a piece of work covered by a provisional sum may cost more or less once the full scope is known.
If a cost changes, don't be afraid to ask questions. Your builder should be able to explain what has changed, why it has happened, and what it means for your budget. No one likes surprise costs, so it is worth making sure you understand where they have come from.
What is a variation?
A variation is simply a change to what was originally agreed. It could be swapping out a product, changing part of the design, adding extra work, or dealing with something unexpected that has been uncovered on site.
Before saying yes, make sure you know what the change will cost, whether it will affect timing, and if there are any other options worth considering. Then get it in writing so everyone is working from the same information.

Every project has a timeline, but building is not always predictable - that doesn’t mean timelines should be vague though!
You should have a clear idea of the major stages, what could affect them, and how your builder will keep you updated if things shift.
What are the key steps on a build timeline?
Your builder should be able to explain the main stages of the project and what needs to happen before each part can begin, including managing the specialist subtrades. For a new build, that might include site works, foundations, framing, roofing, services, lining, finishing and final checks. For a renovation, the timeline may be less straightforward, especially if parts of the existing home need to be opened up before decisions can be made.
Your builder will coordinate the specialist trades needed for your project, but many subtrades are in high demand and working across several jobs, so even with a well-managed plan, one delay can affect when the next trade is available and create a knock-on effect across the wider programme.
What can cause delays?
Whether it’s the weather, council inspections, product availability, subcontractor scheduling, design changes or unexpected site conditions, there’s numerous things that can slow the process down.
Some delays are outside anyone’s control. What you can expect is clear communication about what has changed, why it has changed, and what it means for the next stage.
As work takes shape, you’ll start noticing the finer details.
A few small fixes are normal on any build or renovation, but it helps to know what needs attention, what standards apply, and how your builder will work through it with you.
What are defects?
Defects are things that need to be fixed because the work hasn’t been completed to the required standard. Some are easy to spot, while others may only become obvious later on. These are normal and there will be minor defects at the end of any project. The builder will be aware of this and will let you know the timings for getting them addressed. Some may also require other sub-trades to come back on site to address them.
That said, not every small mark, gap or finish issue is automatically a defect. There are industry standards that help determine what is considered acceptable and what needs to be put right.
What are tolerances?
Tolerances are the accepted allowances for certain aspects of building work, particularly when it comes to finishes and appearance. These are set by Government officials, and they help determine what is considered acceptable and what may need to be put right.
That doesn’t mean you should ignore something that catches your eye. It just means there are recognised guidelines that help work out whether something falls within the expected range or needs attention. If you are unsure, ask your builder to talk you through it.
