A tiler warranty is the tradesman's written promise to come back and fix faults in their own work for a set period, usually somewhere between 12 months and 7 years. The catch is that not all warranties cover the same things, and the words on the page matter far more than a handshake at the front door.
This guide explains the difference between workmanship and product warranties, how waterproofing guarantees fit in, and exactly what to get in writing before a single tile goes down. It sits within our guide to Choosing and Hiring a Tiler in Adelaide.
The two warranties on every tiling job
Almost every tiling job carries two separate warranties, and homeowners often assume they are one and the same. They are not, and knowing the difference tells you who to chase when something goes wrong.
Workmanship warranty (the tiler's promise)
This is the tiler guaranteeing the labour: that tiles are laid flat, bedded properly, spaced evenly, grouted correctly and will not lift, crack or go drummy because of how they were installed. If a tile pops up 8 months later because of a poor bond, that is a workmanship claim.
A workmanship guarantee typically runs 12 months to 6 years in Adelaide, and the length says a lot about how confident the tiler is in their own work.
Product warranty (the manufacturer's promise)
This covers defects in the materials themselves: the tiles, the adhesive, the grout and the waterproofing membrane. It comes from the manufacturer, not the tiler, and it usually only applies if the product was installed to the maker's specification.
That last point is the trap. If a tile fails and the manufacturer inspects it, the first thing they check is whether it was laid correctly. A product warranty can be voided by poor workmanship, which throws the claim straight back onto the tiler. This is exactly why the two warranties need to work together.
| Feature | Workmanship warranty | Product warranty | |---|---|---| | Who backs it | The tiler | The manufacturer | | What it covers | Labour, laying, grouting, waterproofing application | Faulty tiles, adhesive, grout, membrane | | Typical length | 12 months to 6 years | 10 to 25 years (product dependent) | | Common reason it fails | Business closes, dispute over cause | Voided by incorrect installation | | Who you claim from | The tiler directly | The supplier or manufacturer |
Waterproofing guarantees deserve their own line
Waterproofing is the single most important part of any wet-area job and the most expensive thing to get wrong. A failed membrane behind a shower can rot framing and destroy the room below, and by the time you see it, the tiles are already down.
In South Australia, waterproofing a wet area is a licensed task and typically costs $500 to $1,500. Because it is hidden the moment tiling starts, you need its guarantee spelled out separately from the general workmanship warranty. Ask the tiler:
- Who is doing the waterproofing and are they licensed for it (see do tilers need a licence in SA? for what the licence actually covers)
- What the guarantee period is on the membrane specifically, not just the tiling
- What product was used and its batch details, so a future claim has the paperwork behind it
- That it was done to Australian Standards (AS 3740 for wet areas), which is not optional
If a tiler waves this off or bundles it into a single vague line, treat that as a warning. Proper operators are happy to itemise waterproofing because it shows they did it correctly.
What the law already guarantees in South Australia
Even without a written warranty, tilers doing residential work under a building contract in SA are bound by statutory building warranties. Under the Building Work Contractors Act, that means roughly 5 years cover for structural defects and 2 years for non-structural, running from when the work finishes.
Two things worth knowing:
- These minimums apply whether or not the tiler mentions them, so a business offering "12 months" is not the ceiling of your protection on contracted work.
- For jobs over the threshold value, home warranty insurance can apply, which is one more reason a properly insured tiler matters if the business later closes.
A written warranty from the tiler sits on top of these legal minimums. It should extend or clarify them, never undercut them.
What to get in writing before work starts
A verbal promise is close to worthless if the tiler moves on, changes numbers or simply forgets. Before you accept a quote, get the warranty terms in writing. A solid warranty statement should cover:
- How long the workmanship guarantee runs, with a clear start date
- Exactly what is covered: lifting, cracking, drummy tiles, grout failure, waterproofing
- What voids it: building movement, water damage from other trades, DIY repairs, harsh cleaners
- The waterproofing guarantee as a separate, stated period with the product named
- The products used, so manufacturer warranties can be claimed if needed
- How a claim works: who you contact, expected response time, and who pays for access or making good
If a tiler will not put their guarantee in writing, that tells you how likely they are to honour it. Knowing what to ask for is a big part of how to choose a tiler in Adelaide with confidence rather than crossed fingers.
A warranty is only as good as the tiler behind it
Here is the uncomfortable truth: a 7-year workmanship warranty from a cash-only operator with no licence and no insurance is worth almost nothing. If they vanish, there is no business left to honour it, and chasing a defunct sole trader is slow and rarely successful.
The warranty that actually protects you comes from a licensed, insured tiler with a traceable business, a real address and a track record. That way the piece of paper has something solid standing behind it.
