Why vetting a tiler matters
Tiles are only as good as the surface beneath them, the waterproofing behind them and the care taken during installation. In New Zealand, a poor tiling job can lead to cracked grout, lifting tiles, leaks into adjoining rooms and costly rework. That risk is even higher in bathrooms, laundries, kitchens and outdoor areas, where moisture and movement are part of everyday use.
A reliable tiler will usually be happy to answer questions, provide a written quote, explain the preparation involved and give you a realistic timeframe. By contrast, unreliable or dodgy operators often rely on pressure, vague promises and a lack of paperwork. Knowing the warning signs early can save you money and stress.
Red flag 1: Cash-only payment or pressure to avoid invoices
Cash-only arrangements are not automatically illegal, but they are a common warning sign when they come with a refusal to provide an invoice, written quote or any proof of payment. If a tiler says they can do a “special deal” if you pay cash and keep things off the books, be cautious.
Why it matters:
- You may have no paper trail if the job goes wrong. - It is harder to prove what was agreed, including the price, timeline and scope. - You may have less protection if you need to dispute the work later. - A refusal to invoice can indicate poor record-keeping or tax evasion.
A professional tradesperson should be able to accept normal payment methods and provide an invoice with their business details, GST number if registered, and a clear description of the work.
Red flag 2: No written quote or only a vague estimate
A proper tiling quote should spell out what is included and what is not. If someone only gives you a rough number over the phone or in a text message, that is a sign to slow down.
Look out for:
- “It’ll probably be around $X” with no breakdown - No mention of tile removal, substrate preparation or waterproofing - No details about grout, adhesive, trims or sealants - No allowance for travel, parking, waste removal or disposal - No estimated start date or completion date
In New Zealand, labour and material costs can vary a lot depending on tile size, pattern, site access and whether the job is in a renovation or a new build. A written quote helps you compare like for like. It also reduces the chance of surprise extras later.
If the quote is too short, ask for a more detailed version before committing. If a tiler refuses, treat that as a red flag.
Red flag 3: A large upfront deposit demanded before any work is booked
It is normal for some tradespeople to ask for a deposit, especially if they need to order special tiles, trims or waterproofing materials. But a large upfront payment without a clear reason can be risky.
Be careful if the tiler:
- wants most or all of the money before starting - says the deposit is needed “to secure the job” but gives no written terms - asks for a transfer to a personal account instead of a business account - becomes pushy when you ask how the deposit will be applied
As a general rule, any deposit should be reasonable, documented and linked to actual costs. For example, if custom tiles are being ordered, a deposit may cover those materials. The quote should clearly state the deposit amount, when it is due and whether it is refundable if the job is cancelled.
Never pay the full amount upfront unless you have a very clear contract and strong reason to trust the business. For larger jobs, it is better to agree staged payments tied to milestones.
Red flag 4: No physical address or only a mobile number
A tiler who operates only from a mobile number, social media page or messaging app may be legitimate, but the lack of a physical address should prompt more checking.
Why this matters:
- It can be hard to serve a formal complaint if something goes wrong. - You may not know whether the business has an actual base in your region. - It can be a sign of a short-term operator who disappears after a dispute.
At minimum, ask for:
- the business name - an email address - an invoice or quote with a physical business address - a landline or business contact, if available - proof of the company’s legal identity, if they are trading as a company
For local homeowners, it is also worth asking whether the tiler regularly works in your area. A nearby business may be easier to contact for follow-up fixes or warranty work.
Red flag 5: Pressure tactics and “today only” pricing
A trustworthy tiler should not rush you into signing before you have compared quotes or checked references. Be wary if you hear lines like:
- “I’ve got a gap in the programme today only.” - “You need to decide right now or the price goes up.” - “I can start tomorrow, but only if you pay now.” - “Don’t worry about the details, we’ll sort it later.”
Pressure tactics often try to stop you from asking sensible questions. In New Zealand, most homeowners get at least two or three written quotes for renovations, especially where waterproofing, substrate repair or bathroom retiling is involved. If someone tries to stop you doing that, it is a strong warning sign.
A genuine professional will understand that good homeowners want time to check credentials and compare scope, not just headline price.
Other warning signs to watch for
| Warning sign | What it can mean | What to do | |---|---|---| | No references or recent photos | Little proven experience, or photos may not be their own | Ask for current references and examples of similar NZ jobs | | Won’t explain waterproofing | Risk of leaks and non-compliant work | Ask exactly who is doing waterproofing and what system is used | | Avoids site visit | Quote may be guesswork | Request an on-site measure before accepting a price | | Poor communication | Likely delays, mistakes or conflict | See how quickly they respond and whether answers are clear | | Unusually cheap price | Missing labour, materials or proper prep | Compare the scope, not just the number | | No GST invoice when expected | Poor administration or unregistered business | Ask for an itemised invoice and confirm GST status | | No written warranty terms | Hard to chase defects later | Ask what workmanship guarantee applies and for how long |
NZ-specific checks before you hire
Tiling itself is generally not a licensed trade in the same way plumbing, gasfitting, drainlaying or electrical work is. However, tiling often sits alongside work that does have regulatory implications, particularly in bathrooms, kitchens and outdoor areas.
Before you commit, check whether your project involves:
- **plumbing or drainage changes**: these may need a licensed plumber, gasfitter or drainlayer under the Plumbers, Gasfitters, and Drainlayers Board (PGDB) - **electrical work**: any associated electrical work must be carried out by a suitably authorised person under the Electrical Workers Registration Board (EWRB) rules - **building work or waterproofing alterations**: some renovation work may need a building consent from your local council, especially if you are altering wet areas, moving walls or changing structural elements - **significant waterproofing**: ask who is responsible for the membrane and whether the system meets the relevant New Zealand standards and manufacturer instructions
If the tiler brushes off these issues or says “consents don’t matter”, that is a major red flag. In NZ, the homeowner can still be responsible for making sure work is done correctly and, where needed, consented.
Questions a reliable tiler should answer willingly
You do not need to be an expert to hire a good tiler. A few direct questions can quickly separate a professional from a problem.
Ask:
- Are you able to provide a written quote with GST, if applicable? - What exactly is included in the price: prep, waterproofing, adhesive, grout, sealant, trims and clean-up? - Who will handle waterproofing, and is it included in the quote? - Do you have recent references from similar jobs in New Zealand? - Do you carry public liability insurance? - What deposit do you require, and when is the balance due? - What is your expected start date and programme? - What happens if hidden damage or uneven substrate is discovered?
A reliable tiler should answer clearly, without getting defensive. If the response is vague or evasive, keep looking.
How to protect yourself before paying anything
Before you agree to the job, take a few practical steps:
- Get at least two or three written quotes. - Compare the scope, not just the total price. - Check the tiler’s website, reviews and recent projects, but don’t rely on reviews alone. - Ask for references you can contact directly. - Confirm the business name, contact details and invoice information. - Get the agreed price, materials, start date, finish date and payment schedule in writing. - Keep copies of texts, emails, photos and receipts. - If the job is in a wet area, confirm waterproofing responsibilities before work starts.
For outdoor tiling in particular, timing can matter in New Zealand’s wetter months. If someone insists on rushing a winter job without discussing weather protection, curing times or site conditions, that may be another sign they are prioritising speed over quality.
If you think you’ve hired the wrong person
If warning signs appear after the job has started, act early.
- Stop making payments until the issues are clarified in writing. - Photograph the work and keep a dated record of concerns. - Ask for a written plan to fix defects or complete missing items. - If the tiler is a company, communicate formally by email as well as phone. - If necessary, get a second opinion from another qualified tradesperson.
For serious disputes, the path you take may depend on the size of the job and how it was contracted. If consumer law issues are involved, you may need advice on your rights under New Zealand law. For certain payment disputes or workmanship problems, the Disputes Tribunal may be an option.
The bottom line
The biggest red flags when hiring a tiler are usually the same ones: no written quote, cash-only dealings, large upfront deposits, no real business address and pressure to sign quickly. Add poor communication, vague scope and reluctance to discuss consent or waterproofing, and you have a recipe for trouble.
The safest approach is simple: slow down, get multiple written quotes, check the business details and choose the person who is clear, professional and willing to put everything in writing. That extra care up front is far cheaper than fixing a bad tiling job later.
