Questions to Ask a Concreter Before You Hire Them
Choosing a concreter is a genuine trust decision — the work is largely permanent and expensive to redo. Here are the questions worth asking before you commit to anyone.
Licensing and Insurance
Ask directly whether the contractor holds the appropriate registration for the work involved, and confirm they carry current public liability insurance and, for larger domestic building work, appropriate domestic building insurance. This isn’t a formality — it protects you if something goes wrong, and a legitimate, established contractor should have no hesitation confirming these details clearly.
Engineering and Compliance
Ask how the slab or structure will be engineered — is a current soil report being used, will the design be certified by a structural engineer, and does the project need a building permit. A contractor who can explain this process clearly, rather than glossing over it, is a genuinely good sign. Be wary of anyone suggesting engineering or permits can be skipped to save time or money — this is not a legitimate shortcut on compliant work.
What’s Actually Included in the Quote
Ask specifically what’s included: site preparation and excavation, plumbing/electrical rough-in coordination, engineering, the concrete itself, reinforcement, finishing, and cleanup. A lower quote that excludes several of these compared to a more comprehensive one isn’t necessarily better value — it may just be missing scope you’ll need to pay for separately later. Getting quotes itemised in genuinely comparable detail is worth insisting on.
Experience and References
Ask about experience with projects similar to yours specifically — a contractor experienced in driveways may not have the same depth of experience with a challenging reactive-soil house slab, for example. Asking for examples of similar completed work, or references you can genuinely follow up, is reasonable and a well-established contractor should be able to provide this without difficulty.
Warranty and Defects Cover
Ask what warranty or defects liability period applies to the work, and what it actually covers. This should be explained clearly and, ideally, in writing as part of your contract — a contractor who is vague about warranty terms is worth treating cautiously.
Red Flags to Watch For
Be cautious of quotes significantly below others without a clear explanation of why (missing scope is the most common reason), pressure to pay a large deposit upfront before any real work has started, reluctance to put agreements in writing, and vagueness around engineering, permits or insurance. None of these alone is necessarily disqualifying, but together they’re worth taking seriously before committing to a contractor for what’s typically a significant, largely permanent piece of work on your property.

Frequently Asked Questions
Is it reasonable to ask a concreter for references?
Yes, absolutely — a well-established, genuinely experienced contractor should be comfortable providing examples of similar completed work.
Should every quote include engineering costs?
Compliant slab work requires engineering, so this should be accounted for in your quote or process somewhere — ask directly if it isn’t clearly itemised.
What's a reasonable deposit to pay upfront?
This varies by project and contractor, but a large deposit requested before any real work or material commitment has occurred is worth questioning.
Why do concrete quotes vary so much between contractors?
Differences in scope, inclusions, engineering approach and site assessment thoroughness are the most common genuine reasons — it’s rarely just differing profit margins.
Does a lower quote always mean lower quality?
Not always, but a significantly lower quote without clear justification often reflects missing scope or corners being cut, worth clarifying directly before assuming it’s simply better value.
