A painting contract should name each colour, brand and sheen in writing, require the customer's signed approval of a dry sample on their own wall before the first coat, and treat any work outside the written scope as a priced change order signed before it starts. AI can draft the wording; a local lawyer should check it.
Those two clauses carry most of a painting contract's weight because most painting disputes are about them: "that's not the colour I chose" and "I assumed that was included". The rest of the contract (price, payment, access, insurance) looks much the same in every trade. What is specific to painting is how colour and extras get agreed.
Contract rules vary a great deal between places: limits on deposits, cancellation rights for contracts signed at home, payment timing, warranty minimums. An AI cannot know yours, so it works here as a drafter and a checker, never as the authority. Nothing in this page is legal advice.
The running example is a four-room interior repaint priced at $5,900, with a bold new colour in the lounge. The figures are illustrative.
The clauses a painting contract has to settle before the first coat
| Clause | The question it answers | What goes wrong without it |
|---|---|---|
| Parties and property | Who is hiring whom, and who may authorise work at the property? | A tenant orders extras that the owner refuses to pay for. |
| Scope | Which rooms, surfaces, coats and exclusions are included? | "I assumed the ceilings were included." |
| Colour approval | Which colour, brand and sheen, approved how and when? | "That is not the colour I chose." |
| Preparation and protection | Who moves furniture, fills damage and covers floors? | Arguments over unfilled cracks and paint on carpets. |
| Change orders | How does extra or different work get priced and agreed? | Verbal extras that turn into unpaid work. |
| Access and conditions | When can the crew work, and what must be empty, switched on or reachable? | Delays nobody priced. |
| Payment | Deposit, stage payments, final payment, and what happens if one stalls? | A job half-finished and half-paid. |
| Warranty | What do you stand behind, for how long, with which exclusions? | Every later mark becomes your problem. |
| Hazardous materials | What happens if old paint or materials look hazardous? | Work carries on where it should have stopped. |
| Completion | How is the job signed off and are snags listed? | Final payment held back over marks nobody recorded. |
| Cancellation and disputes | How can each side end the contract, and how are disagreements handled? | Costs with no agreed route to settle them. |
The proposal carries the scope detail, so the contract points to it by date and version instead of repeating it. The painting proposal tutorial covers writing that document. The sections below spend their words on colour and changes, and touch payment and warranty only where those two interact with them.

Buy nowColour approval: record the paint, not just its name
A colour name is not a specification. The same name from two brands, or the same brand in two sheens, looks different on a wall. The contract needs a schedule that records what was chosen, and an approval step that happens on the customer's own wall. For the running example, the approval sheet is completed on the first morning.
| Room | Surface | Brand and line | Colour name and code | Sheen | Coats |
|---|---|---|---|---|---|
| Lounge | Walls | [Brand] [interior line] | Deep teal, [code] | Matt | Primer plus 2 |
| Lounge | Ceiling | [Brand] [ceiling paint] | Brilliant white, [code] | Flat | 2 |
| Hall and stairs | Walls | [Brand] [interior line] | Warm white, [code] | Eggshell | 2 |
| Hall and stairs | Woodwork | [Brand] [trim line] | Pure white, [code] | Satin | Primer plus 2 |
| Kitchen | Walls | [Brand] [washable line] | Sage, [code] | Satin | 2 |
| Bedroom | Walls | [Brand] [interior line] | Soft grey, [code] | Matt | 2 |
Below the table go the signature, the date and time of approval, and a photo of the sample on the wall. Paint makers give the same advice, which is why the contract should require it. Benjamin Moore's guidance on colour samples says to brush out at least two coats, to look at the colour from morning to evening under natural and artificial light, and, for exteriors, to use white foam board because its liquid samples are made for interior use only. The same page says its liquid samples come in an interior eggshell finish, and that colours may shift or fade sooner than expected because samples are not tested for long-term performance.
Four contract points follow from that.
- Approve the sheen separately. An eggshell sample says little about a matt finish. Record the sheen on the approval sheet and say what finish the sample was in.
- Sample on the wall that will be painted, in two coats, not on a chip. For exteriors, say on the sheet that the sample is a board and that long-term colour is the manufacturer's matter.
- Give the customer a window, and say what happens if they do not respond. Whether silence can count as approval is a question for your lawyer, because the rules on it vary.
- Keep the evidence. A signed or e-signed sheet plus a photo of the sample in place settles most later arguments.
Here are three versions of the colour clause, for three common situations. Square brackets mark the points for you and your lawyer to settle, such as the approval window and whether silence can count as approval.
A. Customer chooses the colour. The Customer chooses each colour, brand, product and sheen listed in the Approval Sheet. Before the first coat in each room, the Contractor will apply a sample of at least two coats to a wall in that room, and the Customer will approve it in writing within [two] working days of being invited to. Approval fixes the colour, brand, product and sheen recorded on the Approval Sheet. The Customer accepts that a colour looks different in different light, at different times of day and beside different furnishings, and that printed charts, screens and photographs are not accurate guides. A finished surface that matches the approved sample is not a defect.
B. Change of colour after approval. A change to an approved colour, brand or sheen after the first coat has started is a Change Order under clause [number]. It is priced for the extra coats, labour and materials it needs, and it may move the completion date.
C. Matching an existing colour. Where the Customer asks the Contractor to match an existing colour, the Contractor will arrange a match through [the paint supplier's matching service] and the Customer will approve a sample in the same way. Matching is on a best-efforts basis. Slight differences between new and aged paint are not defects.
A trade tip that sits outside the contract: many painters ask the supplier to tint all the paint for one colour at the same time and mix the cans together before starting a room, so small differences between cans do not show up as a change across a wall.
Change orders: the triggers, the form and the rule about signing first
A change order is a short signed document that says what is changing, what it costs and what it does to the schedule. It works because it is signed before the extra work starts. Five things usually trigger one.
- The customer asks for something new: another room, a second colour, a different sheen.
- The crew finds a condition the proposal did not cover, such as water staining, failed old paint, rot in a window frame or wallpaper under the paint.
- A colour change needs more coats than the proposal allowed.
- Access problems or delays outside your control, which move the time more than the price.
- A product the customer approved is discontinued or unavailable.
- Stop work on the affected area and photograph the condition or note the request.
- Write the change in one paragraph: what, where and why.
- Price it as labour hours at your rate plus materials, and state the effect on the completion date.
- The customer signs or e-signs before the extra work starts.
- Add the change to the running contract total and invoice it with the stage it belongs to.
Everything rests on step 4. A change order signed after the work is a request for payment. Signed before, it is an agreement. Some contracts also let tiny changes be approved by text message below a set figure. That figure is a business decision to settle with your lawyer, and the contract should say how such approvals are recorded.
Change orders. No work outside the scope in the Proposal dated [date] will be carried out, and no price will change, unless the Customer has signed a Change Order describing the work, the price and any effect on the completion date. A Change Order may be signed on paper or electronically. Where the Contractor finds a condition that could not reasonably have been seen when the Proposal was written, such as concealed water damage, failed existing coatings or rotten timber, the Contractor will stop work on the affected area, tell the Customer and propose a Change Order.
In the running example, the first change order arrives on Tuesday, after the furniture is moved and a water stain shows behind a wardrobe.
| Field | Change Order 1 |
|---|---|
| Contract | Four-room interior repaint, $5,900 |
| What and where | Bedroom ceiling: stain found behind the wardrobe. Spot-prime with stain-blocking primer and add one finish coat to the ceiling. |
| Why | Not visible when the proposal was written. Photo attached. |
| Labour | 3.5 hours at $55 = $192.50 |
| Materials | $38.00 |
| Change total | $230.50 |
| Effect on schedule | Half a day |
| Customer signature and date | Signed before the work starts |
On Wednesday the customer sees the first coat of deep teal on all four lounge walls and asks for a soft white instead. The sample on Monday looked right, but a 60 cm square and a full wall are different things. This is Change Order 2: an extra primer coat and two finish coats over the teal, 12 hours at $55 = $660, materials $210, total $870, two days added. The contract sum is now $5,900 + $230.50 + $870 = $7,000.50. The clause did not stop the regret, but it priced it fairly and in writing, which is its whole job.
Hidden-condition changes turn up in every trade. The roofing change order for rotten decking applies the same structure to a different hidden condition.
Warranty wording: your workmanship versus the paint maker's promise
Two different promises get blurred. Yours covers how the paint was applied. The maker's covers the product, on the terms it publishes. The contract should say which is which and what you will do about each.
- Period. A figure you and your insurer are comfortable standing behind. Leave it in square brackets for the AI draft and settle it yourself.
- What it covers. Peeling, blistering or flaking caused by application, such as poor preparation or the wrong number of coats.
- Exclusions. Movement or cracking of the surface underneath, leaks and moisture, mould, stains that bleed through, damage by other people, normal wear, fading, and areas the customer asked you not to prepare.
- Claims process. Written notice with photos within [number] days, your inspection within [number] days, and a remedy by repair or touch-up. Say that touched-up areas may differ slightly in colour or sheen from aged paint.
- Manufacturer's warranty. You pass on any product warranty that applies and you are not the manufacturer's agent.
- Minimum protections. Some places give customers rights a contract cannot remove. Ask your lawyer which apply where you work.
The workmanship warranty tutorial goes deeper on drafting the exclusions list, which is where most of the argument happens.
Payment terms that survive a stalled customer
The payment clause needs three things an AI cannot choose for you: the deposit and stage figures, what triggers each stage, and what happens when one is missed. Tie stages to events ("when preparation is complete in all rooms") rather than dates, so a delay on either side does not break the schedule. State that each change order is invoiced with the next stage. Say that work may pause after written notice if a stage is unpaid, and add late fees or interest only as local rules allow. Final payment follows the final walkthrough, with snags listed in writing. The snag list and final walkthrough tutorial covers that step, and the painting invoice tutorial covers deposits and chasing.
| Stage | Trigger | Share | Amount on $5,900 |
|---|---|---|---|
| Deposit | On signing | 25% | $1,475 |
| Second payment | Preparation complete in all rooms | 35% | $2,065 |
| Final payment | Walkthrough done and snags listed | 40% | $2,360 |
| Total | 100% | $5,900 |
The split is illustrative. What matters is that the three amounts add back to the contract sum, which is exactly the kind of thing an AI check can test and a person should confirm.
Drafting with AI: three passes, then what goes to your lawyer
Treat the AI as two different tools: a drafter that works from your own clauses, and a checker that reads the finished draft. Run them in separate chats so the checker reads the draft cold. OpenAI's own terms say not to treat output as a sole source of truth, which is the right attitude for a contract.
Pass 1: draft from your clause list.
Draft a residential painting contract from the clause list below. British English, plain words, sentences under 30 words.
Rules:
- Use my wording for "Colour selection" and "Change orders" exactly as written. Do not edit it.
- Use [placeholders] for names, addresses, amounts, dates, the warranty period and anything that depends on local law.
- Do not add any clause that is not on my list.
- Do not choose a governing law, a dispute process, an interest rate or a cancellation period. Write [lawyer to decide].
- Number the clauses and define each capitalised term once.
CLAUSE LIST: parties and property; scope (refer to the Proposal dated [date]); colour selection [my wording]; preparation and protection; change orders [my wording]; access and conditions; payment; warranty; hazardous materials; completion and snagging; cancellation; disputes.
Pass 2: check the draft against the list.
Compare the contract below with my clause list. Do not rewrite anything. Report:
(a) any clause on my list that is missing;
(b) any capitalised term used but never defined, or defined twice;
(c) every number, date, percentage and deadline in the contract, with its clause number;
(d) any clause or phrase that was not on my list;
(e) any place where two clauses contradict each other.
An illustrative report from a pass like this reads: "(a) None missing. (b) 'Works' is used in clause 3 and 'Services' in clause 5 for the same thing; 'Premises' is never defined. (c) Clause 4.2: deposit 25%. Clause 7.1: payment table totals 110%. Clause 9.1: claims notice within 14 days; clause 9.3: 28 days. (d) Clause 14: binding arbitration. Clause 6.4: work treated as accepted after three days. (e) Clauses 9.1 and 9.3 disagree."
Items (b), (c) and (e) are plain drafting errors to fix, and the 110% total is the one that would have cost money. Item (d) is two clauses nobody asked for. They come out, or they go to the lawyer marked as questions. An arbitration clause changes how disputes are settled, and that is a decision for a lawyer, not a drafting default.
Pass 3: read it as the homeowner would.
For each clause, write one sentence explaining what it means to a homeowner who has never signed a trade contract. Then flag any clause where your explanation is softer or broader than the clause's literal wording.
Where the plain explanation and the clause disagree, the clause is usually badly written. Fix the clause, not the explanation. These are the slips to expect from an AI draft of a trade contract.
- An arbitration clause or a liability cap that nobody asked for.
- The wrong party words (buyer and seller, landlord and tenant) after the model drifts towards a different template.
- An invented notice process, or a lien-type right that may not exist where you work.
- "Approval within two working days" quietly softened into "deemed approval".
- A "lifetime" or "guaranteed" warranty.
- Your brand and sheen lines replaced by "high-quality paint".
What goes to the lawyer is a short pack: the final draft with every [lawyer to decide] item highlighted, your clause list, the pass 2 report, and five questions. Are there limits on deposits and stage payments? What cancellation rights does the customer have? What late-payment charges are allowed? What warranty minimums and exclusions apply? What are the duties if old paint or materials look hazardous? A lawyer handed a draft with the open questions already marked has less to untangle than one handed a blank page. Once the draft is cleared, it becomes your template, so that cost is spread across every job.
A last check before every new job
The template is reused, so the risk moves from drafting to filling in. Before each contract goes out:
- Every square-bracket placeholder is filled or deliberately removed.
- The rooms, surfaces and colours on the approval sheet match the proposal.
- The payment amounts add up to the contract sum, which a calculator confirms.
- The proposal date and version named in the scope clause are the ones the customer accepted.
- The names and address are right, and none of them went through an AI chat.
When the work is done, the colour approval sheet, the signed change orders and the snag list are the three documents that answer almost every dispute. Keep them together with the contract, and keep the dry-sample photos with them. If you want to check colour options with the customer before the sample goes on the wall, AI colour visualisation can narrow the shortlist, but a rendered wall is not a painted one, and the sample still decides.
Questions painters ask about contracts and AI drafts
Does an email count as colour approval?
It is often useful evidence, but whether it binds anyone depends on your contract and the rules where you work. A safer record is a one-page approval sheet naming brand, colour code, sheen and rooms, signed or e-signed, with a photo of the dry sample on the wall. Ask your lawyer whether small changes may be approved by email.
Can I use a free template and skip the lawyer?
A template is a starting structure, not a check. Rules on deposits, cancellation rights, payment timing and warranties vary between places and can override what the contract says. Pay a lawyer who knows local contract rules to read the final draft once, then reuse it. The cost is spread across every job you sign.
How long should a painting warranty last?
That is a business decision to make with your lawyer and your insurer, not a figure to copy from an AI. Decide what you will actually stand behind, say whether it covers workmanship only, list the exclusions plainly and set a claims process with notice and photos. Some places set minimum protections that a contract cannot remove.
Is it safe to paste a customer's address into ChatGPT or Claude?
You do not need to. Drafting a template uses clauses and placeholders, not customer data. Keep names, addresses and prices out of the prompt and fill them in afterwards in your own document. Use a business plan, or a personal plan with training switched off, for anything that does include real details.
