Why guarantees matter when hiring a flooring installer
A new floor is a visible, high-wear part of your home, and mistakes can be expensive to fix. In New Zealand, a flooring installer should be able to explain what they guarantee, how long for, and what happens if something goes wrong after the job is finished.
That matters because not all problems come from the same source. A squeaky or lifting floor might be caused by poor installation, but it could also be due to the wrong product being chosen for the room, moisture issues in the subfloor, or a manufacturing defect in the flooring itself. Good installers separate those risks clearly.
Before you sign anything, get multiple written quotes and ask each installer to spell out:
- what is covered by their workmanship guarantee
- what product warranties apply
- what exclusions or conditions apply
- who to contact if there is a problem after completion
That written clarity is just as important as price.
The three layers of protection: workmanship, product, and consumer law
When you hire a flooring installer in New Zealand, there are usually three different protections in play.
| Protection | What it covers | Who is responsible | What to check |
|---|---|---|---|
| Workmanship guarantee | Faults caused by the installer’s labour, such as poor laying, visible joins, incorrect adhesive use, or failed finishing | The flooring installer | Length of guarantee, exclusions, inspection process |
| Product warranty | Defects in the flooring material itself, such as premature wear, delamination, or manufacturing faults | The manufacturer or supplier | Warranty period, maintenance rules, proof of purchase |
| Consumer Guarantees Act (CGA) | Services must be carried out with reasonable care and skill, and goods must be of acceptable quality and fit for purpose | The business you dealt with, and sometimes the supplier/manufacturer for goods | Whether the service was obtained for personal, domestic or household use |
A reliable installer will not hide behind fine print. They should be willing to explain where their responsibility ends and the supplier’s begins.
What a workmanship guarantee should cover
A workmanship guarantee is the installer’s promise that their labour meets a reasonable standard. For flooring, that usually means the installation should be carried out carefully, to the manufacturer’s specifications and to normal trade standards.
A useful workmanship guarantee should cover issues such as:
- loose boards, tiles or planks caused by poor fixing or inadequate adhesive
- visible gaps, lipping or uneven transitions caused by poor installation
- incorrect preparation of the subfloor before laying the flooring
- damage caused by careless cutting, fitting or finishing
- skirting or trims left poorly fitted as part of the job
- failure to follow the manufacturer’s installation instructions where those instructions were provided
Ask how long the guarantee lasts. A short guarantee is not automatically bad, but it should make sense for the product and the work. For example, a minor repair job may reasonably have a shorter workmanship guarantee than a full-house timber or vinyl installation.
Also ask whether the guarantee includes labour only or both labour and materials used by the installer, such as adhesives, underlay, trims or fixings. Some installers guarantee only their labour, while others stand behind the full completed job.
What product warranties usually do — and do not — cover
Product warranties come from the flooring manufacturer or supplier, not usually the installer. They can cover defects in the flooring material itself, but they almost always come with conditions.
Common examples include:
- laminate or engineered timber that delaminates unexpectedly
- vinyl that cracks or bubbles due to a manufacturing fault
- carpet that shows premature fibre failure beyond normal wear
- tiles with batch defects, colour variation beyond tolerance, or structural faults
Product warranties often do not cover:
- poor installation
- incorrect cleaning products
- moisture damage from leaks or flooding
- wear and tear that is expected for the product’s class
- damage caused by moving furniture, pets, or sharp objects
- issues caused by not following care instructions
For that reason, a strong installer will confirm that the flooring product is suitable for the room. In NZ homes, this is particularly important in kitchens, laundries, bathrooms, entryways and other areas where moisture and temperature changes can affect performance. Winter damp, poor underfloor ventilation, and coastal humidity can also matter.
Ask the installer to provide:
- the product brand and exact product name
- the warranty period
- a copy or link to the manufacturer’s warranty terms
- any maintenance requirements that must be followed to keep the warranty valid
If the installer recommends a product, make sure that recommendation is in writing.
What the Consumer Guarantees Act means for flooring work
The Consumer Guarantees Act 1993 (CGA) gives New Zealand consumers extra protection when they buy goods and services for personal, domestic or household use.
For flooring installation, the main service guarantees are that the installer must:
- carry out the service with reasonable care and skill
- complete the service within a reasonable time if no time is agreed
- charge a reasonable price if no price is agreed
- use materials that are reasonably fit for the purpose if they supply them
If the floor is installed badly, the CGA may give you the right to have the problem fixed. If the failure is substantial — for example, the floor is clearly unusable, unsafe, or would cost a lot to properly remedy — you may be able to reject the service and seek a refund or other compensation, depending on the circumstances.
The CGA cannot usually be contracted out of for household consumers. Be cautious if a quote or contract says the business is not responsible for defects in workmanship or hides behind very broad disclaimers. Those terms may not override your statutory rights.
Signs of a trustworthy guarantee
A good flooring installer does not just say “we guarantee our work”. They explain what that means in practical terms.
Look for guarantees that are:
- Written down: included in the quote, contract or invoice
- Specific: they list what is covered and for how long
- Realistic: they match the type of flooring and the job scope
- Clear on exclusions: such as flooding, structural movement, or pre-existing subfloor issues
- Backed by credentials: the business is easy to identify, contact details are current, and any supplier relationships are disclosed
You should be wary of:
- vague promises with no timeframe
- “lifetime” guarantees that exclude almost everything in the fine print
- a refusal to put warranty terms in writing
- a quote that avoids mentioning subfloor preparation, moisture testing or underlay where those steps are necessary
Questions to ask before you hire
Use these questions to compare installers before accepting a quote:
- What workmanship guarantee do you provide?
- Does your guarantee cover both labour and installation materials?
- What product warranty comes with the flooring, and who backs it?
- Have you installed this exact product before?
- Do you follow the manufacturer’s installation instructions?
- Will you check moisture levels or subfloor condition before starting if needed?
- If a problem appears later, how do I make a claim?
- What would void the warranty or guarantee?
- Will I receive care and maintenance instructions in writing?
- Are there any extra costs if the manufacturer needs to inspect a defect?
If the installer is also supplying the flooring, ask whether they take responsibility for co-ordinating a warranty claim with the supplier. That can save time and confusion later.
Common warranty exclusions and how to handle them
Many flooring warranties and guarantees contain exclusions. Some are reasonable; others deserve close attention.
Typical exclusions include:
- water damage from leaks, spills left unattended, or flooding
- normal wear and tear in high-traffic areas
- damage from pets, furniture movement or dropped objects
- fading from direct sun if UV protection or curtains are not used
- failure caused by poor ventilation or high moisture levels
- problems due to previous building defects, such as a weak or uneven substrate
Before the job starts, ask the installer whether they see any risks that could affect the warranty. In older NZ homes, this can include moisture in timber floors, out-of-level slabs, or previous renovation work that wasn’t done well.
If a pre-existing issue is discovered, get it documented before the floor is laid. It is much easier to sort out a subfloor problem early than to argue later about whether the new floor caused the defect.
Do you need a building consent or other licensed trade?
Most routine flooring installation does not require a building consent. However, there are important exceptions.
You may need to think about consent or other specialist work if the job involves:
- structural changes to the floor or subfloor
- altering load-bearing elements
- significant waterproofing work, especially in wet areas
- work that forms part of a larger renovation requiring consent from the local council
Flooring installers are not normally doing regulated plumbing, gasfitting, drainlaying or electrical work as part of a standard flooring job. But if your renovation includes moving power points, altering plumbing fixtures, or changing shower waterproofing details, those tasks must be done by appropriately authorised people under the relevant NZ rules.
If you are unsure, ask the installer what parts of the work they will do themselves and what will need other trades or council approval.
What to do if the flooring is faulty
If something looks wrong, act quickly. Early reporting makes it easier to establish whether the problem is workmanship, product failure or a site issue.
A sensible approach is:
- Document the issue — take dated photos and videos, and note when the problem first appeared.
- Check the paperwork — review the quote, contract, warranty terms and any care instructions.
- Notify the installer in writing — describe the fault clearly and ask for an inspection.
- Keep using the floor carefully — do not make the problem worse if you can avoid it.
- Follow up promptly — keep copies of emails, texts and notes from phone calls.
If the installer agrees it is their fault, ask for a written plan to fix it, including timeframe and who pays. If they believe it is a product issue, they should tell you how the warranty claim will be handled.
Your options if the installer won’t fix it
If the installer refuses to put things right, you still have options in New Zealand.
Depending on the situation, you can:
- make a formal written complaint to the business
- rely on the CGA if you are a consumer covered by it
- ask for an independent inspection or assessment
- seek help from the Citizens Advice Bureau or a community law centre
- consider mediation or the Disputes Tribunal for a relatively low-cost dispute resolution pathway
Keep in mind that the best outcome is usually achieved with clear evidence: the quote, photos, warranty terms, receipts and any communication about the problem. If the flooring installer or supplier has a formal complaints process, use it.
If the job was part of a larger renovation managed by a builder, main contractor or project manager, contact them as well, because responsibility may sit across more than one business.
What to look for in a good quote and contract
A solid quote is one of the best forms of protection. It should reduce the chance of disagreement about what was included.
Ideally, it should state:
- the exact flooring product and quantity
- underlay, adhesives, trims and finishing details
- subfloor preparation and moisture testing, if required
- who supplies and who installs each component
- the workmanship guarantee period
- any separate product warranties
- expected start and finish dates
- what happens if hidden issues are found once work starts
If you are comparing several installers, do not focus only on the lowest price. A quote that is cheaper because it skips subfloor preparation, uses inferior adhesives, or offers no clear guarantee can cost more in the long run.
Final checks before you sign
Before accepting an installer, make sure you have:
- at least two or three written quotes
- a clear description of the flooring product and installation method
- written workmanship guarantee terms
- the product warranty in writing
- confirmation of any exclusions or maintenance requirements
- the installer’s full business details and contact information
A flooring installer who is confident in their work should be happy to provide this. Good guarantees do not just protect you after the job — they are often a sign that the installer knows how to do the job properly in the first place.
