Choosing a builder is one of the most significant decisions you’ll make for your home. Get it right and the whole experience is manageable, even enjoyable. Get it wrong and you’re dealing with delays, cost blowouts, and a lot of stress.
The good news is that most of the things that separate a reliable builder from a problematic one are visible before you sign anything. You just need to know what to look for.
Here’s what we’d focus on if we were in your shoes.
Check That They’re Licensed and Properly Insured
In NSW, any builder doing work valued above $5,000 must hold a current contractor licence issued by NSW Fair Trading. For residential building work above $20,000, a builder also needs to provide Home Building Compensation (HBC) cover, which protects you if the builder dies, disappears, or becomes insolvent before the work is complete.
These aren’t formalities. They’re the minimum legal requirements, and both are easy to verify. You can check a builder’s licence status directly on the NSW Fair Trading website by searching their name or licence number. If a builder is reluctant to share their licence details, that tells you something.
Beyond licensing, ask about their public liability and contract works insurance. A licensed builder without adequate insurance is still a risk.
Look for Relevant Experience, Not Just Years in Business
Experience matters, but the right kind of experience matters more. A builder with 30 years of commercial fit-out work isn’t the same as a builder with 30 years of residential custom homes and renovations in your area.
Ask specifically about projects similar to yours. If you’re planning a renovation on an older home in Newcastle, ask whether they’ve done that kind of work before and whether they can show you examples. If you’re building a custom home in Lake Macquarie, ask how many they’ve completed in the last few years and what the process looked like.
A builder with a strong local track record will have no hesitation here. They’ll be able to point you to completed projects, show you a project gallery, and connect you with past clients who are happy to talk.
Understand What’s in the Quote Before You Compare Prices
A low quote is not always a good quote. In building, price comparisons are only meaningful when you’re comparing the same scope of work.
When you receive quotes, go through each one carefully and ask:
- What’s included in the price and what’s a provisional sum or prime cost item?
- What assumptions has the builder made about site conditions, soil type, or existing structure?
- What are the payment stages, and do they align with actual progress milestones?
- Are council fees, engineers’ reports, and certificates included, or are they extras?
Provisional sums and prime cost items are estimates, not fixed prices. If a quote is full of them, the final cost can end up significantly higher than the number you agreed to. A builder who takes the time to nail down these figures upfront is doing you a service, even if their quote looks higher initially.
Pay Attention to How They Communicate from Day One
How a builder handles the quoting and consultation phase is usually a reliable indicator of how they’ll handle the build itself. If they’re slow to respond, vague about details, or hard to get in front of before you’ve signed anything, don’t expect that to improve once your money is on the table.
The things worth noticing early:
- Do they return calls and emails promptly?
- Do they explain things clearly without talking over your head or rushing through?
- Do they ask questions about what you actually want, or just push toward a quick decision?
- Are they upfront about timelines, including realistic lead times and any current workload constraints?
Building a home or doing a significant renovation means months of working closely with your builder. You want someone you can have a straight conversation with, including when things don’t go exactly to plan.
Ask Whether They Have a Clear Building Process
A builder who has done this many times before will have a structured process for taking a project from initial consultation through to handover. They’ll be able to explain each stage, what happens at each milestone, and how they keep clients informed along the way.
This matters because the building process has a lot of moving parts: design and approvals, site preparation, construction stages, inspections, and final certification. A builder without a clear process tends to manage these reactively, which leads to delays and surprises. A builder with a well-defined approach keeps things on track and keeps you informed throughout. You can see how we approach this on our building process page.
Ask how they handle variations (changes to scope during the build), how they communicate progress updates, and what happens if there’s a delay. Their answers will tell you a lot about how organised they are.
Ask for References and Read Them Seriously
Most builders will offer references if asked. The value is in how you use them. Don’t just collect names. Actually, call the people on the list and ask specific questions:
- Did the project finish close to the original timeline?
- Were there cost variations, and how were they handled?
- How did the builder communicate during the project?
- Would you use them again?
Online reviews and client testimonials can also give you a broader picture. Look for patterns rather than individual comments. A builder with consistently positive feedback about communication and transparency is telling you something important.
