Hiring a concreter is not just about getting the lowest quote. The right questions help you spot experience, avoid hidden costs, and make sure the finished work suits New Zealand conditions, from coastal corrosion to heavy winter rain. A good concreter should answer clearly, explain the process, and be upfront about what is and is not included.
Why asking the right questions matters
Concrete looks simple when it is finished, but the quality depends on what happens before the truck arrives, during the pour, and in the curing period afterwards. Poor preparation, rushed finishing, or the wrong mix can lead to cracking, surface dusting, drainage issues, and costly repairs.
Asking direct questions also helps you compare quotes fairly. Some contractors include excavation, formwork, mesh, and disposal, while others only price the pour itself. In New Zealand, where site access, weather delays, and council requirements can all affect the job, clarity matters.
Questions to ask before you accept a quote
• Are you licensed, insured, and experienced with this type of job?
• What is included in the quote, and what counts as an extra?
• What concrete mix and reinforcement do you recommend for my site?
• How will you prepare the base and manage drainage?
• How long will the job take, and what can delay it?
• What warranty or workmanship guarantee do you offer?
A good concreter will not just say “yes” to these questions. They should explain why their approach suits your site, your use case, and local conditions.
Questions about experience, credentials, and insurance
1. Have you done similar jobs before?
If you are getting a driveway, patio, shed slab, path, or exposed aggregate finish, ask for examples of similar work. A concreter who mostly does small paths may not be the best choice for a large driveway with vehicle loads or a sloping site.
Good answers sound like this:
• “Yes, we do several driveways and slabs each month, including on sloping sections.”
• “We can show you recent jobs similar to yours and explain the finishes used.”
• “We have worked with clay soils, tight access sites, and coastal properties.”
2. Are you insured and do you hold the right licence or trade credentials?
In New Zealand, concreting companies should carry public liability insurance, and their workers should be appropriately trained. Not every concreting job requires a specific building consent, but that does not mean the contractor should be casual about compliance.
Good answers sound like this:
• “Yes, we have current public liability insurance and can provide evidence.”
• “We’ll let you know if your job may need council involvement or consent.”
• “We follow NZS 3109 and industry best practice for placement and finishing.”
If a contractor is vague about insurance or compliance, treat that as a red flag.
Questions about the quote and what you are actually paying for
3. What exactly is included in the price?
This is one of the most important questions to ask before hiring a concreter in NZ. A quote that looks cheaper may exclude excavation, spoil removal, steel mesh, edge thickenings, saw cuts, sealing, or access setup.
Ask for an itemised breakdown so you can compare like for like.
Good answers sound like this:
• “This includes site measure-up, base preparation, formwork, reinforcement, pour, finish, and clean-up.”
• “These items are extra: old concrete removal, difficult access, pump hire, and council inspection delays.”
• “We’ll note any provisional costs so you know what may change.”
4. What sort of price range should I expect?
Costs vary by site, finish, thickness, and access, but these indicative NZ ranges can help you sense whether a quote is realistic:
• Plain concrete driveway: about $120 to $220 per square metre
• Plain concrete patio or path: about $100 to $180 per square metre
• Exposed aggregate: about $180 to $300 per square metre
• Decorative or coloured finishes: about $160 to $280 per square metre
• Small slab or repair job: often priced as a minimum job, sometimes $1,500 to $4,000+
Extra costs may apply for excavation, steel, cartage, pump hire, difficult access, and demolition of old concrete. In many NZ regions, weather and access can also affect labour time and total cost.
Questions about preparation, drainage, and durability
5. How will you prepare the ground before pouring?
Good concrete work starts with a properly compacted base. On many NZ sites, especially those with clay soils or fill, poor preparation is a major cause of cracking or sinking.
Good answers sound like this:
• “We will excavate to the required depth, compact the base, and confirm levels before pouring.”
• “We use the right sub-base material for drainage and load support.”
• “If the ground is unstable, we’ll recommend more preparation rather than risking failure.”
6. How will you handle drainage and falls?
Water management matters a lot in New Zealand’s wet climate. Driveways, patios, and slabs should be laid to fall away from buildings and not direct water towards garages, foundations, or neighbouring properties.
Good answers sound like this:
• “We’ll set falls so water drains away properly and does not pond.”
• “We’ll discuss drainage channels or extra falls if the site is flat or exposed to run-off.”
• “We’ll check the levels against existing door thresholds and access points.”
If the concreter dismisses drainage as unimportant, keep looking.
7. What reinforcement and thickness do you recommend?
The right answer depends on what the slab will be used for. A footpath does not need the same specification as a driveway or garage slab. In NZ, the concreter should explain the thickness, mesh, control joints, and edge details in plain language.
Good answers sound like this:
• “For a vehicle area, we recommend a thicker slab with mesh and control joints.”
• “For a light-use path, we can use a simpler specification.”
• “We’ll tailor the design to soil conditions and expected load.”
Questions about timing, curing, and aftercare
8. How long will the job take, and when can you start?
Weather, workload, and site access all affect scheduling. In NZ, concrete work can be delayed by heavy rain, cold temperatures, or high winds, so you want a realistic timeline rather than a promise that sounds too good to be true.
Good answers sound like this:
• “We can give you a start window, but wet weather may shift the pour date.”
• “The job itself will take X days, plus curing time before use.”
• “We’ll confirm access, materials, and preparation before locking it in.”
9. How long before I can drive or walk on it?
Concrete may feel hard quickly, but it still needs curing time. A decent concreter should explain the difference between light foot traffic and full vehicle use.
Good answers sound like this:
• “You can usually walk on it after about 24 to 48 hours, depending on conditions.”
• “We recommend waiting around 7 days before light vehicle use, and longer for full strength.”
• “We’ll give you care instructions for the first week.”
10. What maintenance does it need?
Good finishes last longer when they are sealed, cleaned properly, and not exposed to harsh misuse. This is especially important for exposed aggregate, coloured concrete, and coastal properties.
Good answers sound like this:
• “We’ll advise when to seal it, if sealing is suitable.”
• “Use mild cleaning products and avoid harsh acids unless recommended.”
• “We’ll explain what kind of cracking is normal and what is not.”
Final checklist before you hire
Before you sign, make sure you have clear written answers to these points:
• What is the exact scope of work?
• What materials and finish are included?
• Who handles excavation, disposal, and clean-up?
• What happens if bad weather delays the pour?
• What is the payment schedule?
• What warranty or support is provided after completion?
A professional concreter should be happy to answer these questions without pressure or jargon. If the answers are vague, rushed, or inconsistent, it is usually better to get another quote.
The best concreter for your job is not always the cheapest. Look for clear communication, practical advice, local experience, and a quote that matches the work you actually need. That is the best way to get a concrete finish that performs well in New Zealand conditions and lasts for years.
