Red Flags When Vetting a SA Contractor

Dodgy contractors don’t advertise it — they hide behind glossy websites and unreturned calls. Here’s how to spot the warning signs before your money leaves the account.

Red Flags When Vetting a SA Contractor — practical guidance from the team running construction work on the Garden Route. Below are the checks that are worth doing, the warning signs that actually predict trouble, and the two documents that protect you more than any amount of due diligence.

Start with the checks that are free

Before you assess anybody on impression, do the verifications that produce a yes or a no. They take an afternoon and they eliminate a surprising proportion of the field.

NHBRC registration. Any builder constructing a new home for another person must be registered, and the home must be enrolled before construction starts. The NHBRC maintains the register and it can be checked. Registration is a floor, not a recommendation — but a builder who is not on it cannot lawfully build your house.

The legal entity. Get the registered company name and registration number, and confirm it exists and is in good standing at CIPC. Check that the name on the quote, the name on the contract and the name on the bank account are the same entity. They are not always, and when they are not, it is worth asking why before rather than after.

VAT registration. If they are charging VAT, they should have a valid VAT number. It is a two-minute check and it is occasionally illuminating.

Insurance. Ask for the schedule, not a statement. Contractors all-risk and public liability, current, with cover appropriate to the value of your project. A certificate that expired last year is a common find.

Letters of good standing. Compensation Fund good standing means their workers are covered for injury on your site. Without it, an injury on your property becomes a problem you did not anticipate having.

Money behaviour is the strongest predictor

If you only watch one thing, watch how a contractor handles money. It predicts trouble more reliably than anything on their website.

Large deposits demanded up front. A modest establishment payment and progress payments against completed work is normal. A demand for a substantial percentage before anything happens on site is not. A contractor who needs your money to start your job is being funded by you, and if the previous job is what actually consumed it, you are now the newest link in a chain.

Payments requested ahead of work done. Progress payments should be valued against what has actually been built. Once payment runs ahead of production, your leverage disappears exactly when you need it.

Pressure to pay into a personal account, or urgency around payment. Both are worth stopping over. So is any change of banking details communicated by email — that is one of the most common construction fraud patterns in South Africa and it costs people real money every year. Confirm changed details by phone, on a number you already had.

Cash discounts for skipping the paperwork. A discount in exchange for no invoice is a discount in exchange for no recourse.

A price notably below the others. Not automatically dishonest — but it means something. Either something has been left out, or the margin is too thin to survive the job, and a contractor who runs out of money mid-build is the worst outcome available. Ask what they have allowed for the specific items you suspect are missing.

What the quote itself tells you

A quote is a work sample. Long before anyone builds anything, it shows you how they document, how they think, and how they will handle a disagreement.

A lump sum with no breakdown cannot be compared to anything, cannot be valued for progress payments, and gives you no basis to price a variation later. It is the format that produces the most disputes.

No exclusions listed is not generosity. Every quote has exclusions; the question is whether they are written down or discovered later. A quote that names what is not included is a more honest document than one that names nothing.

Provisional and prime cost sums with no explanation. These are legitimate tools for items not yet chosen, but they should be identified and realistic. Unrealistically low provisional sums are how a quote gets to a competitive-looking total that has no chance of being the final number.

Vague specification. “Tiles”, “standard fittings”, “paint to client’s choice”. Whoever wrote that will supply the cheapest thing that complies, and they will be entitled to.

No programme, no payment schedule, no variation procedure. Those three define how the job runs. Their absence means it will run on whatever gets agreed verbally under pressure.

References, and how to make them useful

Everybody supplies references and everybody supplies good ones. The information is in how you ask.

Ask for recent work — within the last year or two — and for jobs of similar type and value. A contractor whose references are all much smaller than your project is telling you something about their capacity.

Then go and look. Photographs are curated. Walking a completed house is not. If they cannot get you onto a completed job or an active site, that itself is data.

When you speak to past clients, skip “were you happy”. Ask the questions that produce specifics: Did the final account match the original price, and if not, why? Did they finish on the programme? How did they handle the things that went wrong — because something always does. Did they come back during the defects period? Would you use them again for something bigger?

The last one is the most revealing. People are reluctant to criticise a contractor directly, and much more willing to answer that question honestly.

Ask a supplier too, if you can. Local merchants know who pays and who does not, and a contractor on cash-only terms at the yard is a contractor with a cash flow problem you are about to join.

Behaviour during the vetting period

How somebody behaves while trying to win your work is the best possible sample of how they will behave once they have it. It only gets less attentive from there.

Unreturned calls and emails during pricing. Missed site meetings. Documents promised and not sent. If this is happening while they are competing for the job, consider what it looks like in month five.

Reluctance to put things in writing. “Don’t worry about that, we’ll sort it out on site” is the phrase that appears immediately before every dispute we have ever been asked to comment on.

Pressure and urgency — a price that expires this week, a slot in the programme that will be gone by Friday. Legitimate contractors do have real capacity constraints, and they explain them. Manufactured urgency exists to prevent comparison.

Dismissiveness about contracts, NHBRC or engineers, particularly framed as red tape that adds cost. Every one of those exists because of a failure mode that someone else already lived through.

And a lack of curiosity about your site. A contractor who will price a build without walking the erf either intends to load the price with contingency or intends to recover the unknowns through variations. Neither is good for you.

The two documents that protect you

Vetting reduces risk. It does not eliminate it, and no amount of reference-checking substitutes for the paperwork. Two documents do most of the actual protecting.

A proper building contract. A JBCC Minor Works or Principal Building Agreement, or an NEC or PBA form for larger work. What you get from it: a defined scope, a payment mechanism tied to valued work, retention, a written variation procedure, an extension-of-time mechanism, a defects liability period, and a dispute process. What you get from a one-page quote and a handshake is none of those, and in that vacuum the party with more experience of construction disputes has the advantage. That is not you.

A complete, specified scope. Drawings and a specification detailed enough that two different contractors pricing them would build the same house. This is the document that determines whether “that wasn’t in the price” is a conversation or an argument.

Retention is worth understanding as well: a percentage held back from each payment, part released at practical completion and the balance at the end of the defects period. It is the mechanism that gets a contractor to come back and close out a snag list, and it is why releasing it early is a mistake even when the request is polite and reasonable-sounding.

What good looks like

It is easy to write a list of warning signs and leave the impression that the industry is full of them. It is not. Most builders are competent people trying to run a difficult business in a hard trading environment, and the good ones share recognisable habits.

They ask more questions than they answer at the first meeting, and several of the questions are ones you had not thought about. They walk the site before pricing. They put exclusions in writing without being asked. They are comfortable with a contract, an engineer and an inspection regime, because those things protect them too.

They tell you things you do not want to hear — that the programme is longer than you hoped, that the ground will cost you, that the finish you have chosen is a poor match for the exposure. A contractor who agrees with everything is either not listening or planning to have the argument later.

And they are still contactable after handover. That is the whole test, really, and it is the one you can only apply by asking someone whose job they finished two years ago.

Frequently asked questions

How do I check if a builder is registered with the NHBRC?

The NHBRC maintains a register of home builders and it can be checked directly with the Council. Ask the builder for their registration number and the registered entity name, and verify both — a number alone, on a letterhead, is not verification. Also confirm that the entity registered with the NHBRC is the same entity that will sign your contract and issue your invoices. Registration is a legal minimum for building a new home for someone else, not a mark of quality.

What happens if a builder is not registered with the NHBRC?

They cannot lawfully build a new home for you, and your home cannot be enrolled — which means you lose the structural defects cover that enrolment provides. It also creates practical problems: banks may refuse to release funds, and it will surface later at conveyancing when you sell. If a builder tells you enrolment does not apply or can be sorted out later, treat that as the end of the conversation rather than a detail to negotiate.

Should I pay a deposit to a builder?

A modest establishment payment to cover site setup and initial materials is normal and reasonable. A large percentage of the contract value demanded before work starts is not. The healthy structure is progress payments valued against work actually completed, with retention held back. Once your payments run ahead of what has been built, you have lost the only leverage the arrangement gave you.

How do I compare builders’ quotes?

Only by having them price the same documents. Different builders pricing different assumptions produce numbers that cannot be compared at all. Then read past the total: check the exclusions, the provisional sums, the specification level and the payment terms. If one quote is materially lower, identify what is in the others that is not in it. Usually the gap is visible in the exclusions rather than the rates.

Do I need a written contract with a builder?

Yes, and for anything of consequence use a recognised standard form rather than a quote with a signature on it. A JBCC agreement gives you a defined scope, valued progress payments, retention, a written variation procedure, extension-of-time provisions, a defects liability period and a dispute mechanism. In the absence of those, disagreements get resolved by whoever is more experienced at construction disputes, and that is very unlikely to be the homeowner.

What is retention in a building contract?

A percentage withheld from each progress payment — commonly around five percent — of which part is released at practical completion and the balance at the end of the defects liability period. It exists to give the contractor a financial reason to return and close out the snag list. Releasing it early removes that reason, which is why requests to do so should be declined however reasonably they are put.

Is the cheapest quote always a bad sign?

Not always, but it always warrants an explanation. A lower price can come from lower overheads, better buying, or a genuinely leaner operation. It can equally come from omitted scope, unrealistic provisional sums, or a margin too thin to survive the job. The distinction matters enormously, because a contractor who runs out of money halfway through is the worst outcome on the list. Ask them to walk you through the specific items you suspect are light.
