A practical guide to finding and vetting a renovation builder on the Gold Coast — QBCC licensing, contracts, red flags, and the questions worth asking.
The builder you choose determines everything — your timeline, your budget, the quality of the finish, and frankly, your stress levels for months. We've seen Gold Coast homeowners lose tens of thousands of dollars and years of their lives to the wrong builder. Unfinished kitchens, dodgy waterproofing that leaks into the unit below, builders who vanish mid-project with deposits in hand.
It's not rare. The QBCC handles thousands of complaints every year. The good news is that most of these situations are avoidable if you know what to look for — and what to ask — before signing anything.
In Queensland, any building work valued at $3,300 or more (including labour and materials) must be carried out by a QBCC-licensed contractor. This isn't optional. It's the law. A QBCC licence means the builder has demonstrated technical competence, met financial requirements (so they're less likely to go broke mid-project), agreed to comply with the Queensland Building and Construction Commission Act, and taken out the required insurance.
Go to the QBCC online licence search and enter the builder's name or licence number. Check that the licence is current (not expired or suspended), that the licence class covers residential renovation work, and that there are no current directions or sanctions against them.
Worth knowing: A builder with a "Builder — Low Rise" licence can handle most Gold Coast renovation work. If your project involves structural changes to a building over three storeys, you'll need a builder licensed for medium or open-rise construction.
A Master Builders Queensland membership isn't legally required, but it signals something. Members agree to a code of conduct, have access to ongoing training, and are generally more invested in their professional reputation. It's not a guarantee of quality — but it's one more data point in your favour. Ask for the membership number and verify it.
These aren't trick questions. A good builder will answer every one without hesitation.
1. What is your QBCC licence number? Verify it yourself. Don't take their word for it.
2. Can you provide proof of current public liability and contract works insurance? Both should be current and adequate for your project value.
3. Will you provide a fixed-price contract? If they won't, ask why. Understand the difference between a quote, an estimate, and a fixed price.
4. What is included in the price — and what isn't? Get the inclusions and exclusions listed in writing. Every item.
5. What is the projected timeline, and how do you handle delays? Look for a builder who commits to a schedule, not a vague range.
6. Who will be my day-to-day contact on site? On some projects, you'll never see the person who sold you the job again. Find out who actually manages the build.
7. Can I speak with three recent clients? Not just see photos — actually talk to homeowners who've been through the process.
8. How do you handle variations and unexpected issues? Every renovation uncovers surprises. You want a builder who has a clear process for approving changes and costs before work proceeds.
9. What warranty do you provide, and what does it cover? Queensland law requires minimum warranty periods, but some builders offer more.
10. Do you manage the design process or just the build? A builder who handles concept design through to handover saves you time, money, and the headaches that come from coordinating separate designers, certifiers, and trades.
Watch for these warning signs during the quoting and consultation process. Any one of them is cause for concern. More than one, and you should seriously reconsider.
1. They want a large upfront deposit. Under Queensland law, a builder cannot ask for more than 10% of the contract price as a deposit for contracts over $20,000. If someone asks for 30% or 50% upfront, walk away. It's both illegal and a sign of cash-flow problems.
2. No written contract. A handshake deal isn't a deal. For any domestic building work over $3,300, a written contract is required by law in Queensland. No contract means no legal protection for you.
3. They pressure you to sign quickly. "This price is only good until Friday" is a sales tactic, not a building practice. A confident builder gives you time to review the contract, seek legal advice, and compare options.
4. They can't show you completed projects. Every established Gold Coast renovation builder should have a portfolio of finished work they're proud of. If they can't show you real projects — not stock photos, not renders — that's a problem.
5. They badmouth other builders. Professional builders let their work speak. If someone spends the consultation tearing down competitors rather than explaining their own process, the work ethic tends to match.
6. No permanent business address. A builder working out of a ute with only a mobile number isn't necessarily bad — but it makes it harder to find them if something goes wrong two years later. Look for established businesses with a physical presence on the Gold Coast.
7. Vague or incomplete quotes. A quote that says "kitchen renovation — $45,000" without a detailed breakdown of inclusions, exclusions, and specifications isn't really a quote. It's a number. And numbers without detail change.
Fixed-price contracts mean you agree on a total price before work starts. The builder carries the risk of cost overruns within the agreed scope. You know your total cost upfront, it's easier to budget and finance, and the builder is motivated to work efficiently. The trade-off is it requires a fully detailed scope before signing, with less flexibility for changes during the build.
Cost-plus contracts mean you pay the actual cost of labour and materials, plus an agreed margin or management fee. You get more flexibility to make changes as you go, and it can be faster to get started. But you don't know the final cost until the project is finished, you carry all the risk of cost overruns, and there's less incentive for the builder to manage costs tightly.
Tip: For most Gold Coast home renovations, a fixed-price contract with a clear scope is the safest option. At Concept Design Construct, we finalise the complete scope and selections during the design phase so you get a genuine fixed price — not an estimate with allowances that blow out later.
Your builder must carry QBCC Home Warranty Insurance (for residential work over $3,300 — this protects you if the builder dies, disappears, or becomes insolvent), Public Liability Insurance (covers damage to people or property during construction), and Contract Works Insurance (covers the project itself against damage during the build). Ask for certificates of currency. A good builder will provide them without being asked.
After the build, under the QBCC your builder must provide 6 years and 6 months warranty for structural defects, and 12 months for non-structural defects (cosmetic items, fixtures, fittings). Get the warranty in writing and keep your contract and all correspondence. If a defect appears within these periods and the builder refuses to rectify it, you can lodge a complaint with the QBCC — which is another reason working with a licensed builder matters.
Google Reviews and social media tell you something — but they don't tell you everything. Supplement online reviews with:
Don't rely on a curated portfolio alone. Anyone can photograph their three best projects. You want to know what the everyday standard looks like.
The Gold Coast has specific building challenges that a generic approach won't solve. Salt air corrodes the wrong materials within years. Council requirements vary between City of Gold Coast precincts. Older homes in suburbs like Broadbeach and Southport often contain asbestos. Waterproofing standards are critical in our subtropical climate.
A builder who starts with design — not demolition — catches these issues early. The design phase should include:
This is how projects stay on budget and on time. Skip the design and you pay for it later in variations and rework.
A quality initial consultation should feel like a conversation, not a pitch. The builder should:
If you leave a consultation feeling sold to rather than listened to, trust that instinct. The way a builder treats you during the quoting process is a preview of how they'll treat you during the build.
Before you commit, make sure you can tick every box:
Every region has its quirks, and the Gold Coast is no exception. When you're interviewing builders, pay attention to whether they mention these local factors without being prompted — it's a good sign they know the area:
Choosing a renovation builder on the Gold Coast isn't about finding the cheapest quote. It's about finding someone who understands your home, communicates clearly, builds to a high standard, and stands behind their work. Take your time. Do the checks. Ask the hard questions. The builders who are worth hiring will welcome the scrutiny.
