How to Pick a Concreter Who Won’t Let You Down

A concrete job is one of the more permanent purchases you will make around a house. The driveway, the patio, the slab under a shed or a new extension: once it is poured and cured, you live with it for decades. Get it wrong and you are looking at cracking, uneven surfaces, poor drainage and a repair bill that lands not long after the concreter’s warranty runs out. Get it right and you will barely think about it again.

The problem is that a concreter’s real skill is hard to judge from a website. Anyone can post photos of a clean slab. The trick is knowing what separates a job that lasts from one that starts crumbling at the first heavy rain. This guide walks through the seven things worth checking before you commit, so you can pick a concreter on evidence rather than on a smooth pitch.

1. Check their experience

Concreting looks straightforward, but the difference between a good slab and a bad one is mostly in the details that happen before the concrete even arrives: the ground prep, the formwork, the reinforcement and the mix. An experienced crew has handled the situations that only show up on site, like soft ground, poor drainage or a tight space that needs the concrete placed a certain way.

Ask how long the business has been running and whether they have poured projects like yours before. A team that does house slabs every week is a different proposition from one that mostly does footpaths and is taking on a driveway as a side job. Ask to see recent examples of the same kind of work, ideally jobs finished six months or more ago, because that is when any settling or cracking would have shown.

2. Look for local reputation

Concrete is a local trade, and word of mouth is a better guide than any advertisement. Ask friends, neighbours or family who has done concreting for them and whether they would use them again. A concreter who has worked around your suburb for years has a reputation to protect, and that tends to show up in how carefully they finish a job.

Online reviews help too, but read them the way you would any review. Look for patterns across a decent number of them rather than one glowing write-up. Check that the reviewer is describing work that matches what you want done. A business with a long history of similar local jobs and repeat customers is a safer bet than one with a flashy website and nothing behind it.

3. Verify licences and insurance

This is the step people skip because it feels awkward, and it is the one that matters most if something goes wrong. Concreting work often needs to meet local building rules, and a licensed operator is expected to know them. Ask to see their licence and check that it covers the kind of work you are having done.

Insurance is just as important. If a worker is injured or a wall or pipe is damaged during the job, you do not want that liability landing on you. Ask for proof of public liability insurance before you sign anything, and make sure it is current. A legitimate concreter will not hesitate to show you. Anyone who is vague about licences or insurance is giving you a reason to walk away.

4. Compare quotes on what they include

Price matters, but the cheapest quote is not automatically the best one, and the most expensive is not automatically the best quality. The trick is comparing like with like. A low quote often leaves things out: site preparation, removal of the old concrete, reinforcement, expansion joints or the clean-up afterwards. Those are exactly the costs that come back to bite you later.

Get at least two or three quotes and ask each concreter to spell out what is included. Check that the same scope appears in each one so you are genuinely comparing prices for the same job. Be wary of a quote that is dramatically lower than the others, because in concreting you usually get what you pay for, and cutting corners on the slab under your car is a false economy.

5. Ask about materials and technique

Concrete is not one product. The mix, the reinforcement and the curing method all change how the finished slab performs, and a concreter should be able to talk about them plainly. Ask what strength of concrete they intend to use and whether it suits your project, how they will prepare the base and whether they will include reinforcement such as steel mesh or fibre where it is needed.

Curing is the part most people never see, and it makes a real difference. Concrete gains strength as it cures, and hot or windy weather can dry it too fast and cause cracking. A good concreter plans for that, whether by keeping the surface damp, using a curing compound or timing the pour. If a concreter cannot explain what they would use and why, treat it as a warning sign.

6. Communication tells you how the job will run

How a concreter talks to you before the job is a decent preview of how the job itself will run. Notice whether they return your calls, turn up when they say they will and give straight answers. Concrete is weather dependent and small delays happen, but a concreter who is hard to reach or vague about timing before they have your money is unlikely to improve once they have it.

Ask about the timeline and what happens if it rains, and whether they will let you know about changes. Good tradespeople treat communication as part of the job, not an interruption to it. If you are already chasing them for answers during the quoting stage, imagine doing it halfway through a pour.

7. Get everything in writing

Never rely on a handshake for a job this size. A written contract protects both of you, and it forces the details to be agreed before work starts rather than argued about afterwards. It should set out the scope of the work, the concrete mix and finish, the start and completion dates, the total price and the payment schedule, and the warranty.

Check what the warranty actually covers and how long it runs. Most concreters offer a period where they will come back and fix issues such as cracking or surface defects, but the terms vary. Get the warranty in writing too, and make sure you understand what would void it. A concreter who is happy to put everything on paper is usually a concreter who expects the job to be good enough to stand behind.

The right concreter is worth the legwork

Choosing a concreter is not the most exciting part of a project, but it is one of the most important. The slab under your driveway, patio or extension is expensive to replace, so the small effort of checking experience, reputation, licences, quotes, materials and communication, and then getting it all in writing, is effort well spent.

Take your time, compare a few options and trust the evidence over the pitch. A concreter who has done this kind of work for years, has the paperwork in order and answers your questions directly is far more likely to leave you with a slab you can forget about, in the best possible way.
