A bad concrete job is expensive to fix — and there are plenty of unlicensed operators in Sydney offering "cash deals" that end in cracked slabs and disappearing tradies. Here are the 7 checks to run before you hire anyone to pour concrete.
1. Check the Licence
In NSW, any concreting work over a certain value must be done by a licensed contractor (a Builder licence — Class 3 or similar — or a licensed concreter). Ask to see their licence number and verify it on the NSW Fair Trading website. A licence number like 173183c is public record — anyone can look it up.
2. Verify Insurance
Your contractor must have public liability insurance (ideally $20 million) and workers' compensation. If they damage your property or a worker is injured, you don't want to be liable. Ask for a certificate of currency and confirm it's current.
3. Get It in Writing
A formal written quote covering scope, materials, timelines, and payment schedule protects you. Be wary of anyone who only wants to work "cash in hand" or won't put anything in writing.
4. Check the Guarantee
Quality concrete companies stand behind their work. Look for a written guarantee — the best offer multi-year structural warranties on their workmanship. If someone can't guarantee their work, that tells you everything.
5. Look at Real Past Projects
Ask for recent local references and photos you can verify. Better yet, ask for addresses of past driveways in your area and drive past them. A contractor with 500+ completed projects has a track record you can see.
6. Read Reviews — but Critically
Check Google reviews and look at how the business responds to any negative feedback. A 4.5★ rating with dozens of reviews is more trustworthy than a perfect 5.0★ from only three reviews. Watch for fake review patterns.
7. Trust Your Gut on Red Flags
Demand full payment upfront · have no licence or "forget" it · quote over the phone without seeing your site · pressure you to decide today · have no written guarantee · can't show you real local projects.
Taking time to vet your contractor is the cheapest insurance you'll ever buy. A proper driveway is a 30-year investment — choose someone who'll be around to honour their guarantee.
