Why guarantees matter when hiring a painter
Painting looks simple from the outside, but good results depend on much more than a tidy finish. Surface preparation, weather conditions, product choice, drying times, and application technique all affect how long the job lasts. That is why it is worth asking every painter what guarantees and warranties they offer before you sign anything.
In New Zealand, a painter’s promise may come from three different places:
- a workmanship guarantee from the painter or company
- a product warranty from the paint or coating manufacturer
- your rights under the Consumer Guarantees Act 1993 (CGA)
These are not the same thing. A useful quote should explain what is covered, for how long, and who you can call if something fails.
Workmanship guarantees: what they should cover
A workmanship guarantee is the painter’s own promise about the quality of their labour. It should cover defects caused by poor preparation, application, or supervision rather than paint failure itself.
A strong workmanship guarantee will usually address issues such as:
- peeling, flaking, blistering, or premature failure caused by poor prep
- visible lap marks, drips, patchiness, or inconsistent finish
- staining through where the surface should have been properly sealed
- missed areas, thin coverage, or incorrect product application
- failure to follow the manufacturer’s instructions for primers, recoats, and drying times
Ask whether the guarantee covers both labour and rework materials if a fault is due to the painter’s error. A good guarantee should make it clear whether the painter will repair at their cost, resupply materials, or both.
What a fair workmanship guarantee looks like
For typical residential painting in NZ, a workmanship guarantee often runs for 1 to 5 years, depending on the surfaces, product system, exposure, and whether the work is interior or exterior. There is no standard legal period for all painting jobs, so the key is whether the guarantee is realistic.
Be cautious if a painter offers:
- a very long guarantee with lots of exclusions
- only a verbal promise
- a guarantee that covers everything except the actual problem you are most worried about
- wording that says the guarantee is void if the house is not repainted on a fixed schedule that was never discussed
The best guarantees are specific. They should state the start date, end date, and exactly what counts as a defect.
Product warranties: what the paint manufacturer may promise
Paint and coating brands often provide product warranties, especially for premium exterior systems, roof coatings, waterproofing products, and specialised finishes. These warranties are about the product itself, not automatically the painter’s workmanship.
A product warranty may cover:
- premature breakdown of the coating when used correctly
- defects in the product formulation
- performance failure when the product is applied to an approved substrate using the correct system
However, product warranties often come with conditions, such as:
- the product must be applied exactly as specified by the manufacturer
- the surface must be sound, dry, and properly prepared
- only approved primers or topcoats can be used
- maintenance must be carried out at recommended intervals
- the claim must be lodged within a set time and backed by proof of purchase
If your painter says the paint has a 10- or 15-year warranty, ask whether that is a manufacturer warranty, a system warranty, or just a marketing claim. In many cases, the warranty is only valid if the painter is an approved applicator and the job is done to the manufacturer’s technical specification.
Consumer Guarantees Act rights: your legal back-up
The Consumer Guarantees Act 1993 gives New Zealand consumers automatic rights when they hire a tradesperson for services. For painting, the painter must provide the service:
- with reasonable care and skill
- fit for purpose if you told them what you needed
- within a reasonable time if no time was agreed
- for a reasonable price if no price was set
These rights apply even if the contract says something else, although businesses can sometimes limit CGA rights for commercial clients in certain cases. For most homeowners, the CGA is a key protection.
If the work is faulty, the remedy depends on how serious the problem is:
- for a minor issue, the painter may need to fix it at their cost within a reasonable time
- for a major failure, you may be able to reject the service and seek compensation or have someone else fix it and recover reasonable costs
In painting, a “major failure” might include badly peeling exterior paint shortly after completion because the surface was not prepared properly, or a finish so poor that it does not meet the standard you reasonably paid for.
What to ask for before you hire
Before accepting any quote, ask each painter for written answers to these questions:
- What workmanship guarantee do you offer, and for how long?
- What exactly is covered: labour, materials, or both?
- What is excluded, for example existing substrate damage, moisture problems, or structural movement?
- Do you follow the paint manufacturer’s specification, and can you provide the product data sheets if needed?
- Is the quote based on a full inspection of the property, including any repairs needed before painting?
- Who handles a warranty claim if a product fails: you, the distributor, or the manufacturer?
- Do you have insurance, and does it include public liability cover?
- Will the guarantee remain valid if I sell the house?
It is also sensible to get at least two or three written quotes. The lowest price is not always the best value if the painter uses cheaper products, skims over preparation, or excludes any meaningful guarantee.
A useful comparison: workmanship guarantee vs product warranty vs CGA
| Protection type | Who provides it | What it covers | Common pitfalls |
|---|---|---|---|
| Workmanship guarantee | The painter or painting company | Errors in preparation, application, and labour | Too many exclusions, short claim window, verbal-only promise |
| Product warranty | Paint or coating manufacturer | Defects in the product itself when used correctly | Invalid if applied incorrectly or on a poor substrate |
| Consumer Guarantees Act | NZ law | Services not carried out with reasonable care and skill, or not fit for purpose | Homeowners not realising it still applies even without a written guarantee |
Special NZ factors that affect warranties
New Zealand conditions can be tough on paint systems. UV exposure, coastal salt air, winter moisture, and seasonal temperature swings all affect performance. A painter should take these into account when advising on guarantees.
Exterior work
Exterior painting is more vulnerable to:
- salt air in coastal areas
- strong UV in many parts of NZ
- damp weather and short drying windows in winter
- building movement and timber expansion/contraction
A painter should not promise a blanket “no peeling ever” result. Reasonable guarantees will depend on the surface condition, product system, and whether ongoing maintenance is done.
Older homes
Many NZ homes, especially villas, bungalows, and older weatherboard houses, need more preparation than a newer build. If lead-based paint may be present in an older home, ask how the painter manages safe sanding, containment, and waste disposal. The guarantee should not pretend that hidden rot, moisture ingress, or failed cladding can be painted over and forgotten.
Repainting versus new work
A repaint over sound surfaces is different from a job that includes:
- carpentry repairs
- plaster patching
- mould remediation
- sealing water-damaged areas
- repainting after leaks or renovations
If repairs are part of the job, ask whether those repairs are guaranteed as well, or only the paint finish over them.
What should be in the written quote or contract
A reliable quote should do more than state a price. It should help you understand what the painter is promising and what would happen if something goes wrong.
Look for:
- the exact areas to be painted
- the products and number of coats
- preparation included, such as washing, scraping, filling, sanding, sealing, and priming
- any repairs excluded from the painting price
- weather-related delay terms for exterior work
- the workmanship guarantee period
- who supplies the paint and whether the product warranty is transferable
- payment stages tied to milestones, not just a large upfront deposit
If the painter is vague, ask for clarification in writing before you agree.
What to do if the paint work is faulty
If the finish is not right, act early and keep everything in writing.
Step 1: Document the issue
Take clear photos and note:
- the date the problem first appeared
- where the defect is located
- whether it is worsening
- any relevant weather events, leaks, or moisture issues
Step 2: Notify the painter promptly
Contact the painter or company and explain the problem calmly. Give them a reasonable chance to inspect and put it right. Many genuine problems can be resolved faster if you raise them soon after discovery.
Step 3: Refer to the contract, guarantee, and CGA
Point out the specific guarantee or product claim if relevant. If the painter disputes it, remind them that the CGA still requires services to be carried out with reasonable care and skill.
Step 4: Escalate if needed
If the painter refuses to fix the problem or does a poor repair, you can consider:
- obtaining a second opinion and written assessment from another painter or building professional
- seeking help from Citizens Advice Bureau or a community law centre
- using your payment provider’s dispute process if applicable
- making a complaint through the Disputes Tribunal for many consumer claims if the amount is within the Tribunal’s limit
If the issue is related to damage from a leak, rot, or another building defect, you may need advice from a builder, surveyor, or other specialist as well.
Red flags to watch for
Be careful if a painter:
- refuses to put any guarantee in writing
- says “you don’t need that, our work is always perfect”
- offers a huge guarantee but cannot explain exclusions
- pushes a product warranty but won’t explain the installation requirements
- asks for most or all of the money upfront without good reason
- will not provide references, insurance details, or examples of similar work
A trustworthy painter should be comfortable discussing both the strengths and the limits of their guarantees.
The bottom line
A good painter should stand behind their work, but the best protection comes from understanding the difference between workmanship guarantees, product warranties, and your rights under the Consumer Guarantees Act. Get the promises in writing, compare at least a few quotes, and make sure the guarantee matches the reality of the job, especially for exterior work in NZ’s weather conditions.
If you do run into a problem, document it early and raise it promptly. In New Zealand, you do have recourse if the job is faulty — and a proper written agreement makes that process much easier.
