Construction fraud in Nigeria rarely announces itself. It hides behind confident sales talk, impressive-looking photos, and a smile that puts you at ease just long enough to collect your money. By the time the warning signs are obvious, the advance payment is gone and the builder is nowhere to be found. The good news is that most fraudulent contractors and artisans give themselves away early, if you know what to look for. Here are seven red flags that should make you pause before signing anything, so you can protect your money, your time, and your peace of mind.

1. No Verifiable Address or Business Registration

A genuine contractor should have a real, traceable presence. If a builder cannot provide a physical business address, lacks a registered company name, or becomes evasive when asked for verification documents, consider it a major red flag. Legitimate professionals are transparent – they have nothing to hide and are always ready to prove their credibility.

2. Pressure to Pay a Large Advance Immediately

Creating urgency is one of the oldest tricks in construction scams. If a contractor demands 50% or more upfront before any trust or working relationship has been established and pushes aggressively for instant payment. It is often a setup to disappear before the job even begins. While reasonable mobilisation fees are normal, any demand for a hefty lump sum without a clear, staged payment plan should raise serious alarm bells.

3. No Physical Proof of Past Work

Photos can be copied or borrowed from the internet, but a genuine track record is harder to fake. A credible builder should be able to point you to a completed site you can visit or connect you with past clients you can speak to. If they fail to provide either, or keep making excuses about why you cannot see a finished project, that hesitation is the answer you need.

4. A Quote That Is Suspiciously Low

If one estimate comes in far below all the others, it is rarely because that contractor is simply more efficient. Underpricing is a common bait-and-switch tactic to win the job with a cheap quote, then cutting corners on materials or piling on extra charges once you are locked in. A suspiciously low price without a clear breakdown or staged plan is a warning sign you should not ignore.

5. Reluctance to Sign a Written Contract

If a contractor prefers handshakes and verbal promises over a written agreement, that’s a major warning sign. A proper contract protects both sides, and genuine professionals have no issue putting the scope of work, timelines, and payment schedules in writing. Any resistance to documenting the deal should make you pause immediately, it is often a signal to walk away.

6. Vague or Shifting Answers About Materials

A reliable builder should be able to tell you exactly what brand of cement, gauge of roofing sheet, or type of iron rod they plan to use. Fraudulent contractors, on the other hand, give vague responses or change their story depending on who is asking. The real plan? To swap in cheaper materials once the project is underway and no one is watching closely.

7. No One Else Vouches for Them

Reputable contractors build trust over time, and that trust shows in the people willing to speak for them. If you can’t find a single independent client, supplier, or colleague who will vouch for a builder and every reference seems to come directly from the contractor, that isolation is a red flag in itself.
