Warranties & disputes · Western Australia

If your benchtop fails, three protections apply at once

The manufacturer product warranty covers the slab, commonly 10 to 25 years and usually only if you register it. The fabricator workmanship warranty covers the install, and 12 to 24 months is the Peel norm. The Australian Consumer Law guarantees sit over both with no expiry date. You use whichever gives the better outcome, and you do not have to choose one before you complain.

Warranty is the part of a benchtop quote nobody reads until something goes wrong, and by then the useful moves have narrowed. This page sets out who covers what in Western Australia, how long each protection lasts, the documents worth keeping, what a defect notice should say, and the escalation path in order. It also draws the honest line between a defect and fair wear, because the second one is where most arguments actually sit.

Who covers what, and for how long

What goes wrong	Who covers it	How long	Notes and common exclusions
Slab defect: delamination, voids, resin failure, colour instability indoors	Stone manufacturer, through the fabricator	10 to 25 years, product dependent	Nearly always conditional on registration within 30 to 90 days and on professional installation. Outdoor use is excluded by most engineered stone warranties.
Open or stepped join, uneven overhang, out of level bench	Fabricator, workmanship warranty	12 to 24 months typical in the Peel	Also an Australian Consumer Law failure to use due care and skill, which does not stop at 24 months.
Crack from a sink or cooktop cut-out corner in the first year	Fabricator	Workmanship period	Usually a tight corner radius or missing support. Not covered if a hot appliance sits over it.
Undermount sink dropping or the bond letting go	Fabricator	Workmanship period	Excluded if a plumber or someone else has disturbed the clips or the waste.
Water leak damaging cabinets under the bench	Licensed plumber who did the connection, or your insurer	Plumber workmanship, insurer policy terms	Burst flexible hoses are a common Mandurah claim. See our insurance claim page.
Thermal crack, scorch mark, chemical dulling	Nobody. Owner damage	Not covered	Hot pans, oven cleaner, drain cleaner and bleach are excluded by every stone warranty we have read.
Chips from impact, scratches from a knife or grit	Nobody. Repairable at $150 to $350	Not covered	Report a chip found on handover day before the crew leaves, and it is theirs.
Etching on marble, natural fissures, slab to slab colour variation	Nobody. Inherent to natural stone	Not covered	This is why we ask you to approve the actual slab, not a 100mm sample.
Silicone discolouring or growing mould	Owner maintenance after the first 12 months	Not a warranty item	A re-silicone is a small job. In coastal bathrooms and laundries expect it every few years.
Anything not of acceptable quality, or not fit for the stated purpose	Australian Consumer Law guarantees, against the supplier	No fixed expiry. A reasonable period for the price and type	Cannot be excluded by any contract term. A major failure entitles you to a refund or replacement, your choice.

Escalation, in order, with the time to allow

Step	What you do	Timeframe to allow
1. Written defect notice	Email the fabricator with dated photos, the invoice number and what you want done.	Send within days of noticing. Ask for a reply in 5 business days.
2. Inspection	They attend, look at it in daylight, and put their position in writing.	Allow about 10 business days to get someone there.
3. Agreed rectification	Scope, date and method confirmed in writing before anyone starts.	Allow 20 business days, longer if a replacement slab has to be ordered.
4. Formal letter	A letter of demand referring to the consumer guarantees and setting a deadline.	Give 14 days to respond.
5. Consumer Protection WA	Lodge a conciliation request with Consumer Protection, part of the Department of Energy, Mines, Industry Regulation and Safety. It is free.	Weeks rather than days. It resolves a lot of these.
6. Building and Energy or the Tribunal	Where the work forms part of a regulated building service, lodge a building service complaint. The State Administrative Tribunal can order rectification or payment.	Months. There is a statutory cut-off measured from completion, so do not sit on it.
7. Magistrates Court minor case	File a minor case claim, currently for amounts up to $10,000. A filing fee applies and costs are limited.	Last resort, and rarely needed if steps 1 to 5 were documented.

The Western Australian framework, in plain terms

Two bodies of law sit behind a benchtop job here. The first is the Australian Consumer Law, which is Schedule 2 of the Competition and Consumer Act 2010 and is enforced in this state by Consumer Protection within the Department of Energy, Mines, Industry Regulation and Safety. It gives you guarantees that no contract can sign away: goods must be of acceptable quality and match their description, and services must be carried out with due care and skill within a reasonable time. There is no expiry date on those guarantees. The test is what is reasonable for a product of that price and type, which is why a $9,000 porcelain kitchen that fails in year four is a live claim even though the workmanship warranty ended in year two.

The second is the WA building services framework: the Building Services (Registration) Act 2011 and the Building Services (Complaint Resolution and Administration) Act 2011, administered by Building and Energy, with the State Administrative Tribunal as the decision maker. Alongside them the Home Building Contracts Act 1991 requires a written contract once the value of home building work passes the threshold set under the Act, currently $7,500, and requires home indemnity insurance above a higher threshold, currently $20,000. A standalone benchtop replacement at $2,900 to $8,500 usually sits under both, so in practice your protection is the consumer guarantees plus whatever is written on the quote. If the benchtop is one line inside a full kitchen or renovation contract, the value of that whole contract is what counts, and you should be given the contract and the insurance certificate before work starts.

What to keep, and what a defect notice should say

Keep these seven things somewhere you will find them in fifteen years, because a product warranty can run 25 years and a claim without a product name is close to unwinnable.

The itemised quote and your written acceptance of it, showing scope, edges, cut-outs and inclusions.
The tax invoice with the ABN, and proof of what you paid and when.
The product name, range and colour, plus the manufacturer warranty document and your registration confirmation.
The safety data sheet showing the crystalline silica figure, which also proves the product was legal to install. See the silica rules page.
Dated photos of the finished bench from several angles on handover day.
Every text and email where a change was agreed, especially changes to the edge, the overhang or the sink.
The care instructions you were given, because a warranty can be voided by using the wrong cleaner. Ours are summarised on the benchtop care page.

A defect notice does not need legal language. It needs: the date, your address, the invoice number and the product name; a plain description of what is wrong and where; when you first noticed it; two or three photos with something in shot for scale; what you want done, which is normally rectification; and a date by which you want a reply. Add one sentence saying you consider the issue a failure to meet the consumer guarantees under the Australian Consumer Law. That single line changes the tone of the reply more than anything else you can write.

Defect or fair wear: where the argument actually happens

A defect is something that should not occur in normal use. A join that opens or steps, a bench that is out of level along a run, an overhang that changes width, a sink that has dropped, a crack running out of a cut-out corner in the first year. Those come back to fabrication or installation, and a competent fabricator fixes them without a fight because the alternative is a conciliation file.

Fair wear and inherent behaviour is the other column, and it is where most homeowners are disappointed. Marble etches when acid touches it, and that is chemistry, not a fault. A matte dark surface shows fine scratching after a few years of normal use. Silicone grows mould in a coastal bathroom. Natural stone slabs differ from each other and contain fissures that are part of the stone. Dark engineered stone that has been installed outdoors in full WA sun will fade, and that is why almost every engineered stone warranty excludes outdoor use, a genuinely important detail for an alfresco bench in Halls Head or Dawesville.

The honest note to finish on: the overwhelming majority of these disputes never happen when the scope is clear in writing up front. Which slab, which edge, where the joins land, who removes the old top, who does the plumbing, what the overhang will be, and when the balance is payable. We put all of that on the quote, and we would tell you to walk away from anyone who will not. Two more limits worth stating plainly: we do not warrant material a customer supplies themselves, because we cannot stand behind a slab we did not buy, and no fabricator can warrant a bench sitting on cabinets that are failing, which is covered on the budget page. If a fabricator has since closed, the manufacturer product warranty may still stand if you registered it, which is the best argument there is for filing that paperwork on install day.

Warranty questions from WA homeowners

What warranty comes with a stone benchtop in WA?

Three protections run at once. The manufacturer product warranty covers the slab itself, commonly 10 to 25 years and usually conditional on registering it within 30 to 90 days of install. The fabricator workmanship warranty covers the install work, and 12 to 24 months is the Peel norm. Over the top of both sit the Australian Consumer Law guarantees, which have no fixed expiry and instead ask what is reasonable for a product of that price and type.

Is a hairline crack at the sink cut-out a warranty claim?

If it appears in the first 6 to 12 months, almost always yes. Cracks that start at an internal corner of a sink or cooktop cut-out usually mean the corner radius was too tight, the support was inadequate, or the cabinets were not packed level. That is workmanship. A crack that appears three years in under a spot where a hot pan or a slow cooker lives is thermal damage and is excluded by every stone warranty we have read.

Does WA require home indemnity insurance on a benchtop job?

Almost never on a standalone benchtop. The Home Building Contracts Act 1991 in WA requires a written contract once the contract value passes the threshold in the Act, currently $7,500, and home indemnity insurance above a higher threshold, currently $20,000. Most benchtop replacements land between $2,900 and $8,500, so they sit under both. If the benchtop is part of a larger kitchen or renovation contract, the whole contract value is what counts.

Who do I complain to if a benchtop job goes wrong in Western Australia?

Start with a written defect notice to the fabricator and allow 5 business days for a reply and about 10 for an inspection. If that fails, Consumer Protection within the Department of Energy, Mines, Industry Regulation and Safety runs a free conciliation service for Australian Consumer Law disputes. Where the work forms part of a regulated building service, Building and Energy takes building service complaints and the State Administrative Tribunal can order rectification. The Magistrates Court minor case procedure, currently for claims up to $10,000, is the last resort.

What is the difference between a defect and fair wear on a benchtop?

A defect is something that should not happen in normal use: an open join, an uneven overhang, a sink that has dropped, a crack from a tight cut-out corner. Fair wear and inherent behaviour is different: etching on marble from lemon juice, fine scratches on a matte finish after 5 years, silicone that grows mould after 12 months, or colour variation between two slabs of natural stone. The first is fixed under warranty, the second is maintenance or the nature of the material.

What paperwork should I keep after a benchtop install?

Keep the itemised quote, the signed acceptance, the tax invoice showing an ABN, the product name and range, the manufacturer warranty document plus proof you registered it, the safety data sheet showing the crystalline silica figure, and dated photos of the finished bench. Keep the lot for at least the length of the product warranty, which can be 25 years. A warranty claim with no product name attached is the hardest kind to win.
