The ConcreteOwner Contractor Vetting Standard

1. Scope and purpose

This standard covers residential flatwork: driveways, patios, walkways, public sidewalks, steps, garage floors, pool decks and similar slabs. It covers leveling, repair, resurfacing, sealing, coatings, and removal and replacement.

It does not cover structural foundation work, commercial or industrial concrete, or civil construction. Those involve different disciplines, different licensing questions and different risks, and a standard written for a driveway would be misleading applied to a retaining structure or a foundation wall.

Its purpose is narrow and practical: to move the things that cause disputes from the end of a project to the beginning. It is written to be used during an estimate visit, by somebody with no trade background, without needing anybody's permission.

• Intended user: a homeowner or authorised property decision-maker collecting estimates.
• Intended moment of use: before signing anything, ideally during the estimate visit itself.
• Not intended as: a pass/fail test, a scoring rubric, or a substitute for reading your contract.
• Not a guarantee: applying every item in this standard reduces the chance of a bad outcome. It does not eliminate it, and nothing can.

2. Contractor identity is established, not assumed

You should be able to establish who you are actually contracting with — the legal business name, how long it has traded under that name, a physical business address rather than only a mobile number, and whether the person quoting is the business or a salesperson for it. Trading names change, and a company with a long reputation and a company that adopted its name last spring look identical on a truck.

• Strong: a legal business name that matches the quote, the contract and the insurance certificate, plus a fixed address.
• Weak: a first name and a mobile number, or a quote whose business name differs from the one on the paperwork.
• Ask: what is the exact legal name of the business I would be contracting with, and how long has it operated under it?
• Ask: are you the owner, an employee, or a salesperson working on commission?

3. Licensing is checked where it applies — and it does not always apply

Licensing requirements for concrete work are set locally and genuinely vary. Some jurisdictions require a contractor licence for this work, some require registration rather than licensing, some regulate only above a dollar threshold, and some do not regulate residential flatwork at all. A contractor who says none is required may be telling you the truth about your area.

• Strong: a clear statement of what applies locally, a licence or registration number you can check yourself, and no objection to your checking it.
• Weak: a claim of being "fully licensed" with no number, category or issuing body named.
• Ask: what licensing or registration applies to this work in this jurisdiction, what do you hold, and what is the number?
• Then verify it yourself with the issuing body. A number on a quote is a claim until you check it.

4. Insurance is verified with the insurer, not with the contractor

This is more universal than licensing and more consequential. General liability cover matters because concrete work involves heavy equipment near your house, your neighbour's property and buried services. Where the contractor has employees, workers' compensation cover matters because an uninsured injury on your property can become your problem.

• Strong: a current certificate of liability insurance provided without hesitation, naming the insurer and the policy dates.
• Strong: willingness for the certificate to be sent to you directly by the insurance agent, which is the only version that cannot have been edited.
• Weak: a photograph of a certificate that expired, or reluctance to provide one at all.
• Ask: can your agent send me a current certificate of liability insurance directly?
• Ask: do you carry workers' compensation for anyone who will be on my property, including subcontracted crew?

5. Experience is relevant to your specific job, not just long

Twenty years of commercial slab work is not twenty years of residential lifting, and a crew that pours beautiful patios may rarely handle a sloped driveway or a set of poured steps. What matters is whether they regularly do work like yours, in conditions like yours.

• Strong: specific comparable jobs, in similar conditions, that they can describe in detail — and ideally that you can go and look at.
• Weak: a general claim of experience with no example resembling your project.
• Ask: how many jobs like this one have you done in the last year, and can I see one that has been in the ground two or three years?
• Ask: is the crew that will do my job the crew that did those?

6. Scope is written down and specific enough to argue with

The proposal should state exactly what area is being worked on, what is being done to it, and what is excluded. Vagueness in a quote becomes disagreement during the work, and the party with nothing in writing loses.

• Strong: measured areas, named panels or sections, and an explicit exclusions list.
• Weak: "repair driveway" with a number beside it.
• Ask: what is specifically not included in this price?
• Ask: if we find something unexpected, what part of this scope changes?

7. The proposed method follows from a stated cause

A contractor should be able to say what they think caused the problem, what they looked at to decide, and why their proposed method addresses that cause. A method chosen before a cause has been established is a product being sold rather than a problem being solved. This is the single most informative question in this standard, and the range of answers is enormous.

• Strong: a specific cause, the evidence behind it, and how the method responds to it.
• Strong: a clear answer to what would make them recommend something else.
• Weak: an explanation of the method with no reference to your site.
• Ask: what do you think caused this, and what did you look at to decide?
• Ask: what would make you recommend a different approach here?

8. Materials, base and process are named and checkable

Three things belong in writing here, and all three are common shortcuts. What goes under the concrete: excavation depth, base material, compacted depth and how compaction is achieved — this decides how long the work lasts and it is invisible the day after the job finishes. What the concrete is: slab thickness, reinforcement, and the mix or product, with a reason tied to how the area will actually be used rather than a default applied to every job. And how it is placed and finished: control joint layout, depth and timing determine where the concrete cracks, and the curing method determines how durable the surface will be. Named products can be looked up; unnamed ones cannot.

• Strong: stated excavation depth, base material, compacted depth and how compaction is achieved.
• Strong: a thickness and reinforcement specification with a reason attached to your use of the area.
• Strong: specific products or a mix specification, with data sheets shared on request.
• Strong: a described joint layout with a stated depth and timing after the pour, plus a curing method.
• Weak: "prepare subgrade" as a single line, or the same specification quoted for a footpath and a driveway.
• Weak: "commercial grade" or "industrial strength" with no product named.
• Ask: how deep are you going, what is going back in, and how is it compacted?
• Ask: why that thickness and that reinforcement, for this use?
• Ask: what exactly are you using, and can I see the data sheet?
• Ask: where do the joints go, how deep, and how soon after the pour?
• Ask: how are you curing this, and when can I walk on it and drive on it — two separate answers?

9. Drainage and the underlying cause are addressed, not sidestepped

Water is behind a large share of residential concrete failure, and it is the item most often absent from a quote entirely. Concrete work also changes where water goes. A contractor who raises downspouts and grading before you do is usually the one taking the job seriously, and a quote that includes a drainage correction may be better value than a cheaper one that leaves the cause running.

• Strong: the contractor raises water before you do, and states which way the finished surface will drain.
• Weak: no mention of downspouts, grading or slope anywhere in the conversation or the quote.
• Ask: which way will water run when you are finished, and what happens in heavy rain?
• Ask: if we do not change the drainage, what is your realistic expectation for how long this holds?

10. The warranty is read for scope, not for length

What a warranty covers matters far more than how many years it runs. Many warranties in this trade exclude cracking, settlement, or anything attributed to ground movement — which is most of what actually goes wrong with concrete. A warranty is a contractual promise from a business that has to still exist to honour it. It is not a guarantee of future performance, and it cannot be.

• Strong: a written warranty naming what is covered, what is excluded, what remedy applies and who to contact.
• Weak: a length quoted verbally with no document behind it.
• Weak: a very long term from a very new business — the term is only worth what the business's continued existence is worth.
• Ask: if this settles or cracks in two years, what exactly happens, and who pays for what?
• Ask: is the warranty transferable if I sell the house?

11. Change-order terms are agreed before anybody digs

Concrete work uncovers things — soft ground, an unexpected slab thickness, a buried service nobody knew about. How additional work gets priced and approved should be settled in writing before it happens, because the moment it is discovered is the worst possible moment to negotiate.

• Strong: written change-order terms, with your written approval required before extra work proceeds.
• Weak: "we'll sort it out if it comes up".
• Ask: if you find something unexpected, how is it priced, and who has to approve it before you continue?
• Ask: are change-order rates stated anywhere in this contract?

12. Deposit and payment terms are proportionate and documented

A reasonable deposit is normal in this trade, particularly where materials are ordered for a specific job. What is not normal is a large payment before any work begins, a demand for the full amount up front, or pressure toward a payment method that leaves you no recourse.

• Strong: a written schedule tied to milestones, with a meaningful balance held until completion.
• Weak: a large upfront percentage with no milestones attached.
• Weak: pressure toward cash, or a discount conditional on paying in full before the work starts.
• Ask: what triggers each payment, and what is held back until I have seen the finished work?
• Ask: what happens to my deposit if the work does not go ahead?

13. Permit responsibility is assigned to a named party

Whether a permit is required depends on your jurisdiction and often on whether the work touches a public right of way — a sidewalk, an apron, an approach. Where one is needed, who pulls it, who pays for it and who carries the consequence if the work fails inspection should all be written down rather than assumed.

• Strong: a clear statement of what is required locally, who obtains it, and whose cost it is.
• Weak: "you don't need a permit for this" with no reference to the local authority.
• Ask: is a permit required for this work here, who pulls it, and is it in the price?
• Ask: if this fails an inspection, who is responsible for putting it right?

14. Cleanup, disposal and property protection are in the price

Demolition debris, concrete washout, and the state of your property afterwards. Disposal is a real cost and a frequent exclusion that appears as a difference between quotes. Property protection matters just as much: equipment routes across a lawn, dust from grinding, and protection for anything the work passes.

• Strong: disposal explicitly included, a stated plan for where washout goes, and a described route in and out with protection for it.
• Weak: silence, or debris removal listed as an optional extra.
• Ask: is removal and disposal included, and what does the site look like when you leave?
• Ask: how does equipment reach the area, and what protection goes down on the way?

15. The work is documented, before as well as after

Photographs of the existing condition before anything is touched protect both parties, and photographs of the base and any reinforcement before the pour are the only record that will ever exist of the part that decides how long the concrete lasts. Once concrete is placed, nobody can see what is underneath it again.

• Strong: the contractor photographs the site before starting, and the prepared base and reinforcement before placing concrete, and shares them.
• Strong: a written record of what was actually done, not just what was quoted.
• Weak: no photographs, or only finished-job photographs for their own marketing.
• Ask: will you photograph the base and any reinforcement before the pour and send me those?
• Take your own photographs of the existing condition regardless. It costs nothing and it is the record you control.

16. Questions to ask their references

Speak to references yourself rather than accepting a list at face value. The most informative ones are jobs old enough to have been through a winter or two.

• How long ago was your job, and what exactly did they do?
• Was the final price the same as the quote? If not, what changed and how was it handled?
• Did they turn up when they said they would, and did they finish when they said they would?
• What did the site look like when they left?
• Has anything about the work changed since — cracking, settlement, surface problems?
• Did you need to go back to them about anything, and how did they respond?
• Would you use them again, and is there anything you would do differently?
• Was there anything they told you that you did not want to hear?

17. Red flags

None of these proves anything on its own, and several have innocent explanations. Two or three together are a pattern worth weighing.

Pressure to sign at the visit, or a price only available today

Legitimate pricing survives a night's thought. Urgency manufactured at the kitchen table exists to prevent you comparing.

A price far below the others with no explanation for the gap

Not automatically bad — a contractor with a schedule gap or lower overheads may genuinely be cheaper. But the usual explanations are a thinner base, a thinner slab, no disposal, no permit, or a narrower scope. Ask, and see whether the answer is specific.

Deflection on the cause

A contractor who will not say what they think caused the problem is either not diagnosing it or would rather you did not evaluate their reasoning.

Reluctance to put the specification in writing

Plenty of good contractors write short quotes and will happily expand them when asked. A refusal is different, and it is the item you will most wish you had insisted on.

A warranty described only by its length

Length is the least informative thing about a warranty. Scope, exclusions and remedy are what determine whether it will ever help you.

An unusually large upfront payment, or pressure toward cash

Both reduce your recourse if something goes wrong, and neither is necessary for a contractor with working capital.

Unwillingness to discuss any option other than the one being sold

Specialisation is normal and often means somebody is good at what they do. An inability to name any situation where they would recommend a different approach is not specialisation.

Dismissing a possible structural problem to keep a flatwork job

This is the most consequential one on the list. A contractor who waves away signs of building movement in order to sell you a driveway is putting their invoice ahead of your house.

Door-to-door canvassing immediately after severe weather

Not proof of anything, and some reputable businesses do canvass. But it is the pattern most associated with crews who will not be reachable in two years, so the identity, licensing and insurance checks matter more than usual.

18. Structural escalation policy

19. What ConcreteOwner matching does and does not mean

ConcreteOwner is an independent information and homeowner-matching platform. We do not perform concrete work. We are not a contractor, an engineer, an insurer, a licensing body, a certification body, a trade association or a government agency, and we have no authority over anybody in the trade.

If we pass your request to an independent contractor, that is an introduction and nothing more. It is not an endorsement, not a statement that they meet this standard, and not a guarantee of their workmanship, their pricing, their schedule or their conduct. Any contract you enter into is between you and that business.

We do not guarantee that anybody will contact you, that we can match you at all, or any timeframe for a response. Contractors arrange their own schedules and we do not control them.

At the time of this review no territory on this platform has an assigned contractor, so in practice every request is currently read by a person and answered honestly about availability. When that changes, this section changes with it — and the version number at the top of this page is how you will know.

• No contractor can hold, display or claim anything from this standard. There is no badge, no certificate, no list and no accreditation.
• Applying this standard in full reduces your risk. It does not eliminate it, and no document can.
• If a contractor tells you they are ConcreteOwner-approved or ConcreteOwner-certified, that is a claim about something which does not exist, and it is worth treating as informative.

What we check today

• Nothing about any contractor. No contractor currently holds a territory on this platform, no homeowner request has been passed to one, and we are not going to describe a process we have not run.
• On the homeowner side we do check every request: whether the property is inside a metro we cover, whether the service category has anybody assigned to it, whether the description suggests a structural problem rather than a flatwork one, and whether the submission passes our spam and duplicate checks.
• Every request is classified into one explicit operational state and a person reads it. Where nobody is assigned, we say so rather than passing details to somebody who does not do that work or does not serve that street.

What we intend to request from participating contractors

• Confirmation of the legal business name and a fixed business address.
• Whatever licensing or registration the jurisdiction requires, with a number we can check with the issuing body.
• A current certificate of liability insurance, and confirmation of workers' compensation cover where there are employees.
• Examples of comparable completed work that has been in the ground long enough to be informative.
• Written confirmation that they will provide a specification in writing, honour written change-order terms, and escalate suspected structural problems rather than working around them.
• The operative word in this list is intend. It describes a policy we have written down. It is not a claim that any contractor has been through it, because none has.

What you must verify yourself

• Licensing, with the issuing body rather than with the contractor.
• Insurance, ideally by having the certificate sent to you directly by the agent.
• References, by speaking to them yourself and asking the questions in this standard.
• Comparable completed work, by going and looking at it where you can.
• Everything in the contract you sign, including the warranty document, the payment schedule and the exclusions. Nobody else can do this for you and no platform can do it on your behalf.

What varies by jurisdiction

• Whether a contractor licence or registration is required for residential concrete work at all, and above what threshold.
• Whether a permit is needed, particularly for work touching a public sidewalk, apron or right of way.
• Who is responsible for maintaining and repairing the public sidewalk in front of a property.
• What vertical difference in a public walkway is considered actionable.
• Contract, cancellation and cooling-off rules for home improvement work, including what has to be given to you in writing.
• Because all of these differ, this standard tells you which body to ask rather than giving you a number that would be wrong somewhere.

How to use this without being difficult

You do not need to work through fourteen checkpoints like an interrogation. Most of them come up naturally in a thorough estimate conversation, and a good contractor will cover half of them unprompted.

The useful signal is which ones they raise themselves. That tells you more than the answers do. The contractors you want to hire generally welcome specification questions, because it means the person they are talking to will understand what they are paying for.

Print the checklist, take it with you, and fill it in during the visit. Contractors who are visibly irritated by that are giving you information too.

What to do with a contractor who will not engage

Ask once, in writing, for the missing items. Plenty of competent contractors write short quotes and will expand them without complaint.

A refusal to specify base preparation, slab thickness, warranty scope or payment milestones in writing is a different matter, and it is reasonable to weigh it heavily. Those four items are where the money and the disputes are.

21. Methodology, version and sources

• This standard was assembled from the failure modes that actually generate disputes in residential concrete work: scope left vague, base preparation unspecified, drainage ignored, warranty scope unread, change orders unagreed, and payment weighted too far up front. Each checkpoint exists because leaving that item undefined is what causes the argument.
• It is written as questions a homeowner can ask and answers they can evaluate, rather than as technical requirements they would have to take on trust. Where an item has no single national answer — licensing, permits, sidewalk responsibility, actionable trip-hazard thresholds — the standard names the body to ask instead of supplying a number that would be wrong somewhere.
• It contains no numeric specification requirements. Publishing a required slab thickness or a required base depth as though it were universal would be inventing a code requirement, and requirements of that kind are set locally and vary by use. The standard asks the contractor to state and justify theirs.
• It asserts nothing about any contractor. Section 19 states plainly what ConcreteOwner checks today, which is nothing on the contractor side, and the four-part split above is structured so that a reader cannot mistake an intention for a completed process.
• Version 2.0.0, last reviewed 29 July 2026. Version 1 covered fourteen checkpoints without a published methodology, a structural escalation policy, a matching-limitations section or a printable checklist; this revision adds all four and separates references, red flags and reference questions into their own sections.

Sources

This standard cites no external source, and that is deliberate rather than an omission. It makes no factual claim about climate, soil, material performance or regulation that would need one — every item is either a question to put to a contractor or a description of what ConcreteOwner does. Where an answer depends on local rules, the standard names the body to ask rather than publishing a figure that would be wrong somewhere.
