The clearest red flags of a dodgy tiler are a cash-only demand, no written quote, a large upfront deposit, no licence or ABN, and pressure to sign quickly. Spot any of these and it is time to slow down, ask more questions and get a couple more quotes before you hand over a cent.
Tiling is one of those trades where the damage from a bad operator does not show up straight away. The tiles look fine on handover, then months later the grout cracks, a wall sweats or a shower floor lifts. By then the cowboy is long gone. This guide walks through the warning signs so you can filter them out early. It sits within our Choosing and Hiring a Tiler in Adelaide guide.
The 5 warning signs that matter most
Most horror stories share the same handful of signals. Here they are, ranked by how much trouble they tend to cause.
| Red flag | What it usually means | What to do | | --- | --- | --- | | Cash only, no invoice | No paper trail, no GST, no recourse | Insist on a written quote and receipt | | No written quote | You cannot hold them to anything | Get everything itemised in writing | | Huge upfront deposit | Cash-flow problem or a runner | Cap the deposit at 10 to 20 per cent | | No licence or ABN | Unqualified, uninsured, unaccountable | Verify before you engage | | Pressure to sign now | Stopping you from comparing | Walk away and get more quotes |
1. Cash only, no paperwork
A tradesperson who insists on cash and refuses to give you an invoice is protecting themselves, not you. No invoice means no GST record, no warranty in writing, and almost nothing to fall back on if the job goes wrong.
Paying cash is not illegal, and plenty of honest tilers are happy to take it for a small job. The red flag is the refusal to put anything on paper. If they will not give you a written quote up front and a receipt at the end, that is your answer.
2. No written quote
A verbal price is worthless the moment there is a dispute. A proper quote lists the work, the tiles, whether waterproofing is included, the surface preparation, the removal of old tiles, and the total. Without it, you have no way to compare quotes fairly and no way to prove what was agreed.
Watch for quotes that leave waterproofing off entirely. In a wet area that job should be $500 to $1,500 and clearly itemised. A quote that quietly skips it is either an oversight or a shortcut, and both cost you later. Our list of questions to ask a tiler covers exactly what a complete quote should spell out.
3. A huge upfront deposit
Materials cost money, so a deposit is reasonable, especially on a larger job where the tiler is fronting for tiles, adhesive and waterproofing membrane. What is not reasonable is being asked for half the total, or more, before any work starts.
Here is a rough guide to what fair looks like in Adelaide:
- Small jobs (a splashback, a repair): often no deposit, or a small one to cover the tiles
- Mid-size jobs (a bathroom): 10 to 20 per cent, or enough to cover materials
- Large jobs (whole-house floors): staged payments tied to milestones, not one big lump
If someone wants $3,000 of a $6,000 job before day 1, ask why. A tiler with a healthy business does not need your money to buy the materials for the job in front of them. An oversized deposit is one of the most common ways a cowboy disappears with your cash.
4. No licence, no ABN, no insurance
In South Australia, tiling itself does not require a specific trade licence, but the tiler still needs to be a legitimate, registered business, and any associated waterproofing and building work has its own rules. An operator with no ABN, no public liability insurance and no verifiable business details is a serious risk. If they damage your property or the job fails, you may have no way to recover anything.
Before you engage anyone, check they have an ABN, ask for proof of public liability insurance, and confirm who is doing the waterproofing and whether that person is appropriately qualified. We cover the detail in do tilers need a licence in SA?. Do not take a business card and a confident handshake as proof of anything.
5. Pressure to sign today
The high-pressure close is a classic. Today-only pricing, a mate's rate that expires this afternoon, or a story about a cancellation that means they can start tomorrow if you commit right now. All of it is designed to stop you doing the one thing that protects you: comparing quotes and checking references.
A good Adelaide tiler is usually booked out and in no rush to strong-arm you. If you feel pushed, that feeling is information. Slow the whole thing down and the pressure tells you everything.
Quieter red flags worth noticing
Not every warning sign is dramatic. Some are quiet, and they are just as telling.
- No fixed address or local presence. Door-knockers offering to tile your patio because they "have leftover materials from a job down the road" are a well-known scam.
- No reviews and no references. A tiler who cannot point you to a single recent Adelaide job or a Google review is either brand new or hiding something.
- Vague on waterproofing. If they cannot explain how they will waterproof a wet area and to what standard, that is the most expensive corner to cut.
- Won't show past work. Genuine tilers are proud of their finish and happy to show photos or an address you can drive past.
- Bad or no communication. If they are hard to reach before you have paid, imagine chasing them for a warranty repair after.
What a trustworthy tiler looks like instead
Flip every red flag and you have your checklist. A tiler worth hiring gives you a written, itemised quote with waterproofing costed in. They ask for a fair deposit, not a fortune. They have an ABN, insurance and reviews you can read. They answer your questions without bristling, and they give you the space to compare quotes rather than rushing you.
If you want a fuller framework for weighing tilers against each other, our guide on how to choose a tiler in Adelaide walks through it step by step. The single best protection, though, is simple: never go with a single quote. Comparing 2 or 3 vetted, licensed local tilers on the same job makes almost every red flag obvious, because the dodgy operator stands out against people doing it properly.
