Tiling Business Contracts: What Every New Zealand Contractor Needs to Know

A lot of tiling businesses get into trouble long before a job goes wrong on site. The issue usually starts with the paperwork. A quote gets accepted by text, the scope is vague, nobody spells out who supplies tiles or who pays for waterproofing failures, and a contractor is treated like an employee, or the other way around. When payment is delayed or defects are alleged, those gaps become expensive.

Tiling business contracts matter whether you are a sole trader taking on bathroom renovations, a growing construction subcontractor working under head contractors, or a business hiring tilers for multiple projects. The right agreement helps you pin down scope, pricing, timing, defects processes, health and safety responsibilities, and who carries the risk if materials are damaged or work needs to be redone.

This guide explains what tiling business contracts should cover in New Zealand, the legal issues to check before you sign, and the mistakes that catch construction businesses most often.

Overview

Tiling business contracts should clearly set out who is doing the work, exactly what work is included, how and when payment is made, and what happens if the job changes or a dispute arises. In New Zealand, these agreements often sit alongside wider construction law obligations, consumer protections, contractor arrangements, and site-specific health and safety duties.

The main goal is simple: reduce uncertainty before you sign, before you order materials, and before you rely on verbal promises made on site.

• define the scope of tiling work, exclusions, specifications and finishes
• confirm whether the worker is an employee, independent contractor or subcontractor
• set payment terms, deposits, progress claims, retentions and late payment rules
• allocate responsibility for materials, wastage, storage, access and site delays
• deal with defects, warranties, call-backs and liability clauses for waterproofing or substrate issues
• include change order procedures for extra work and variations
• cover health and safety responsibilities on site
• set out dispute resolution, termination rights and what happens if the project stops

What Tiling Business Contracts Means For New Zealand Businesses

Tiling business contracts are the legal foundation for how a tiling job is priced, performed and enforced. If you are in the construction sector, they are often the document that determines whether you get paid, whether you must fix work at your own cost, and whether a disagreement becomes manageable or messy.

For a small tiling business in New Zealand, contracts usually appear in three main forms:

• a service agreement with a residential or commercial client
• a subcontract under a builder or head contractor
• an agreement with an individual tiler you engage to perform work for your business

Each has different risk points.

Client Contracts For Tiling Work

A client-facing tiling contract should do more than repeat the quote total. It should describe the surface preparation assumptions, materials, layout, grout type, waterproofing responsibility, access requirements, and the standard for completion.

This matters because tiling disputes often arise from things that were discussed casually but never written down. A homeowner may assume tile removal, levelling, waterproofing certification and rubbish disposal are included. The tiler may have priced for installation only. If the written terms are silent, both sides may think they are right.

Where you are dealing with residential customers, New Zealand consumer law can also affect the position. Services provided to consumers generally need to be carried out with reasonable care and skill, be fit for purpose where relevant, and be completed within a reasonable time if timing is not fixed. You cannot simply contract out of those protections in every situation.

Subcontracts Under Builders Or Main Contractors

A subcontract usually places more pressure on the tiler than a direct client contract. The head contractor's standard terms may include strict deadlines, broad defect liability periods, broad indemnities, and pay-when-paid style risk allocation in practical effect, even where the wording is framed differently.

Before you accept the provider's standard terms, check whether the subcontract makes you responsible for things outside your control, such as:

• delays caused by other trades
• damage to completed tiling by later site activity
• defects caused by poor substrate preparation done by someone else
• design suitability where you did not choose the system or materials
• liquidated damages tied to overall project delay

This is where founders often get caught. A short subcontract can still shift major commercial risk.

Contractor And Worker Agreements

If your tiling business hires people to work on jobs, your contract needs to match the real relationship. Calling someone a contractor does not automatically make them one. If you control their hours, direct the way they work, provide the main tools, and treat them like part of the team, the law may view them as an employee despite the label.

That distinction matters for minimum employment rights, leave, KiwiSaver issues, tax treatment, and dismissal risk. You should sort this out before you hire your first worker and before you classify someone as a contractor.

For genuine contractors, an independent contractor agreement should cover scope, invoicing, insurance, tools, health and safety duties, substitution rights where appropriate, confidentiality, and termination. For employees, you need a compliant employment agreement instead.

Legal Issues To Check Before You Sign

The safest time to fix a tiling contract is before work starts. Once materials are ordered and people are booked, your bargaining power drops quickly.

Scope Of Work And Exclusions

Your contract should say exactly what you are doing, and just as importantly, what you are not doing. Vague descriptions like “tile bathroom renovation” are a recipe for disagreement.

Spell out details such as:

• areas to be tiled
• tile type, size, pattern and layout
• edge trims, grout, sealants and finish quality
• whether demolition or removal of existing tiles is included
• whether substrate preparation, levelling or waterproofing is included
• who supplies materials and who is responsible for shortages or delays
• whether waste removal and final clean are included

If your price assumes the substrate is sound, say so. If you are not certifying waterproofing, say so. If you rely on another trade to prepare surfaces, record that dependency clearly.

Variations And Extra Work

Variation clauses protect both sides when the job changes. A proper clause should require changes to be approved in writing, identify how the price will be calculated, and allow extra time where the change affects scheduling.

Without this, extra work often turns into an argument about whether it was included in the original price. That is especially common when clients ask for different tiles, herringbone layouts, additional splashbacks, or last-minute repairs once walls are opened up.

Before you rely on a verbal promise, make sure the contract says a variation only counts if it is recorded and accepted.

Payment Terms And Cash Flow Protection

Payment clauses should be practical, not just legally tidy. Cash flow problems can put pressure on a tiling business faster than almost anything else.

Check points such as:

• deposit amount and when it is payable
• progress payment stages or milestone claims
• when an invoice is due for payment
• interest or default charges on overdue amounts, if any
• whether you can suspend work for non-payment
• whether retentions apply, and when they must be released

If you subcontract, review the head contract timing too. A subcontract that delays payment until broad site sign-off can leave you carrying labour and material costs for far too long.

Defects, Warranties And Call-Backs

Most tiling businesses expect to fix genuine defects. The real issue is making sure the contract defines defects sensibly and does not make you responsible for problems you did not cause.

The agreement should address:

• how defects are notified
• how much time you have to inspect and return
• whether you get the first chance to remedy
• what counts as defective work versus normal wear, movement, misuse or other trade damage
• whether the client must follow product care instructions

Be careful with broad promises around waterproofing performance, slip resistance, substrate movement, or design suitability if those matters depend on third parties, site conditions or products you did not select.

Liability And Insurance

Liability clauses decide who wears the cost if something goes wrong. They should be realistic and proportionate to the work you are doing.

Look closely at indemnities, liability caps, exclusions for indirect loss, and insurance obligations to hold specific cover. A head contractor may ask for public liability insurance and proof of cover. Some jobs may also call for contract works or other project-specific insurance arrangements.

If the contract includes an unlimited indemnity for property damage, delay losses or third-party claims, pause before you sign. The main risk is agreeing to exposure that is far greater than the value of the tiling package.

Health And Safety Responsibilities

Tiling work takes place on active sites, so health and safety wording matters. Your contract should align with your real responsibilities on site and with the wider project arrangements.

That can include obligations around:

• site induction and access rules
• safe use of tools, adhesives and cutting equipment
• dust control and hazardous substances
• protective equipment
• coordination with other trades
• incident reporting and site directions

If you engage contractors or employees, your internal documents should support the same allocation of responsibilities. Contracts should not sit separately from what actually happens on site.

Termination And Dispute Resolution

Every tiling contract should say what happens if the job cannot continue. Termination clauses matter when there is non-payment, serious delay, repeated safety breaches, insolvency, or a breakdown in cooperation.

The contract should also set out a dispute path. Many businesses prefer a stepped process, such as written notice, a meeting between decision-makers, then mediation or another agreed process if the issue is not resolved. A clear process can stop a site disagreement from turning into a deadlock.

Common Mistakes With Tiling Business Contracts

The biggest mistakes are usually practical, not technical. Most happen because the parties trust informal conversations more than the written terms.

Using Quotes As If They Are Full Contracts

A quote can form part of the agreement, but it is rarely enough on its own. Quotes often focus on price and omit timing, exclusions, defects, delay risk, ownership of materials, and dispute procedures.

If your paperwork is just a one-page quote with a total at the bottom, there is a good chance important issues have been left open.

Accepting Another Party's Standard Terms Without Review

Standard form contracts are written to protect the party that drafted them. Builders, developers and commercial clients often use terms that shift broad responsibility down the chain.

Before you sign a contract presented as “standard”, check whether it changes the commercial balance in ways that your quote did not account for. A profitable job can become unprofitable if defect obligations, delay exposure or payment timing are too one-sided.

Failing To Record Assumptions About Site Conditions

Many tiling jobs depend on surfaces being level, dry, stable and ready. If your price assumes that, write it down. If hidden conditions are discovered after work starts, the contract should allow a variation or additional charge.

Without that wording, you may end up arguing over whether remedial work was already included.

Misclassifying Workers

Some tiling businesses engage workers as contractors because it feels simpler. That approach can create risk if the real arrangement looks like employment.

This issue becomes more likely where the worker wears your branding, works set hours, cannot subcontract, uses your equipment, and relies on your business for most of their income. If that sounds familiar, review the arrangement before it becomes a wider compliance problem.

Relying On Verbal Changes On Site

Site work moves quickly, and clients or builders often ask for small changes informally. Those changes usually affect time, materials or labour, even when they seem minor.

If you do not document the change, you may struggle to recover the extra amount later. Good contracts support a simple written variation process so your team can use it in real time.

Promising More Than You Control

Tilers are often asked to stand behind the whole finished result, even where success depends on waterproofers, builders, designers or suppliers. Be careful not to guarantee outcomes tied to inputs you do not control.

Your contract should reflect the limits of your role. You can stand behind your workmanship without taking responsibility for every other element of the project.

Forgetting Consumer-Facing Obligations

When dealing with homeowners or other consumers, your contract does not sit outside consumer law. Statements in quotes, advertising and emails can also matter under fair trading rules.

Do not overstate timelines, product performance or finish quality. If you make a promise to win the job and it is not realistic, the written contract may not save you from the fallout.

FAQs

Does a tiling business need a written contract for every job?

Not every small job will have a long-form agreement, but a written contract or clearly accepted terms are strongly recommended for almost all paid work. The higher the job value or risk, the more detailed the paperwork should be.

Can I use the same contract for residential and commercial tiling work?

Usually not without adjustments. Residential customer work, commercial fit-outs, and subcontracted construction work involve different risk points, payment structures and legal obligations.

What if a builder gives me a subcontract and says it is non-negotiable?

You can still review the terms and identify the main risks before you sign. Even if only a few points can be changed, clarifying scope, defect responsibility, payment timing and delay exposure can make a big difference.

Is a tiler I hire automatically a contractor if they have an NZBN and send invoices?

No. Labels and invoicing help, but they do not decide the issue on their own. The real working relationship matters more than the paperwork title.

Can I exclude all liability for defective tiling work in my contract?

No, not in a blanket way. You may be able to limit certain risks in some business-to-business situations, but consumer protections and general contract principles can restrict how far exclusions go. The wording needs to be careful and context-specific.
