A garage door repair contract should say which work and parts are covered, for how long, what voids that cover and where your liability stops. Yes, AI can draft those clauses in plain language from decisions you make, but a lawyer where you trade must check them, because liability limits and cancellation rights depend on the place and the customer.
AI writes the sentences; you supply the business decisions. A draft built on a one-page decision sheet (warranty period, exclusions, deposit, cancellation tiers, liability cap) comes back usable. A draft built on "write me a garage door contract" comes back generic, and often borrows wording from places whose rules differ from yours. The lawyer then reviews a clean draft plus your list of open questions, which keeps the review short.
Twelve decisions to make before AI writes a sentence
Most weak AI contracts are weak because the owner hasn't decided anything yet, so the model fills each gap with a plausible default. Write the decisions down first. The table is a filled-in sheet for an illustrative four-technician firm that repairs residential doors and fits openers. The choices are examples, not norms; the last column is the part to copy.
| Decision | Example choice | Why it matters |
|---|---|---|
| What the contract covers | Repairs, part replacements and opener installs listed on the quote | Stops "all necessary repairs" becoming unlimited scope |
| Labour warranty | 12 months on workmanship, for the same fault | Affordable once you know your callback rate |
| Parts warranty | The manufacturer's warranty, passed through; we handle the claim | You can't promise more than your supplier promises you |
| Spring rating | Standard rating by default, higher-cycle on request; the rating fitted is printed on the invoice | Customer expectations match the part |
| Exclusions | Misuse, vehicle impact, missing upkeep, corrosion, work by others, wear items such as remote batteries and weather seals | Defines what a callback is not |
| Safety tests | Balance, safety reversal, photo-eyes and release checked and recorded before we leave | Evidence the door was safe when you left |
| Customer duties | Monthly checks as the opener manual describes; no adjusting springs or cables; keep the door area clear | Puts routine upkeep with the owner |
| Payment | Due on completion, with a reminder at 7 days | Cash flow and a clear trigger for chasing |
| Deposit | 30% on special-order doors and parts | Covers stock you can't return |
| Cancellation | Free before an order is placed; costs recovered after | Ties every fee to a real cost |
| Liability | Capped at the job price for property damage, with carve-outs the lawyer confirms | Marks where your exposure stops |
| Complaints | In writing to the office, with a first reply within five working days | A route that isn't a bad review |
Set up a project so the draft keeps your facts
Put the decision sheet, your current terms (if you have any) and your suppliers' warranty documents into a ChatGPT project or a Claude project, so the facts stay with the work. Claude lets free accounts create up to five projects, and ChatGPT projects take uploaded files with limits that depend on your plan. A custom GPT is the wrong home for this: OpenAI is retiring them, most plans can no longer create new ones, and existing GPTs stop running on 11 December 2026. Keep customer names, addresses and photos out of the project. A contract template needs none of them.
Then give the project one standing instruction. This one produces drafts a lawyer can work with:
You are helping a garage door repair company write its customer terms in plain language.
Use only the facts in the attached decision sheet and supplier warranty documents. If a fact is missing, ask me a question instead of guessing.
Write one section at a time. For each clause give the clause (short numbered sentences, no legal Latin), then one line starting "Why:" that says which dispute the clause prevents.
Mark any wording that depends on local law, consumer rules or insurance with [LAWYER: reason].
Never quote or cite statutes, cases or regulators. Never promise more than the decision sheet allows.
Match the spelling and date format your customers use. Call the customer "you" and the company "we".
End each section with a list of your assumptions and questions for the lawyer.Ask for one section at a time (scope, warranty, safety, liability, payment, cancellation), check each against the decision sheet, then finish with a consistency pass: "List every number and time period in the contract and compare each with the decision sheet." That last step catches the common slip where the warranty says 12 months in one clause and a year and a day in another.

Buy nowScope and quote clauses: the gap AI leaves open most often
Ask a model for a scope clause with no guidance and it tends to write something that protects the customer and costs you money. A typical first draft:
The contractor shall carry out all repairs necessary to ensure the garage door operates safely and correctly.
That sentence makes every fault the technician finds your job, at the quoted price. Ask the project for the clause again, with the instruction that the contract covers only the work on the quote and that extra faults need the customer's approval first. The version worth keeping:
We will carry out the work listed on your quote. If our technician finds another fault, they will explain it and its price, and they won't start that work until you agree. We note and photograph any damage we can see before we start, so it is clear what was already there.
Three more lines belong beside it. A price-validity period ("this quote is valid for [30] days"), because spring and door prices move. A compatibility line: we match parts to the door and opener as inspected, and the customer tells us if either has been altered. And an access line: the customer arranges access and clears the space around the door, and the technician may stop and reschedule if the work can't be done safely. The itemised spring and opener quote wording tutorial shows how to list parts so the scope is visible in the price itself.
Parts and labour warranty wording, with a spring sum
The costliest sentence in a repair contract is usually a lifetime promise. Asked for warranty wording, a model often returns "all parts and labour are guaranteed for life against defects". Life of what: the door, the part, the customer's ownership of the house? A promise that open-ended gets tested by the first bad-tempered customer in year six. Split the warranty into short clauses, each tied to a decision on your sheet:
Labour. If the fault we repaired comes back within [12] months because of our workmanship, we will fix it again at no charge.
Parts. Parts we supply carry the manufacturer's warranty. We will handle the claim for you, and fit a replacement under warranty at no labour charge during the first [12] months.
Springs. Springs wear out with use and are rated by the number of times the door opens and closes (cycles). The rating of the springs we fit is printed on your invoice. A spring that reaches its rating is worn, not faulty.
Not covered. Damage from misuse or vehicle impact, corrosion, missing upkeep, work by anyone else, and wear items such as remote batteries and weather seals.
Choose the labour period from your own data. The example firm did 600 jobs last year at an average of $290, about $174,000 of work, and 36 of them needed a free return visit for a workmanship fault within a year, at roughly $85 of technician time and travel each. That is $3,060, or about 1.8% of revenue. If that figure looks tolerable, 12 months is affordable; if it looks painful, fix the callbacks before you lengthen the promise.
The spring clause needs numbers to make sense to a customer. Amarr, a door manufacturer, calls residential garage door springs 10,000-cycle springs in its spring guide, and expects at least seven years from them at three or four uses a day. Run the same sum for your own customers: a household that opens the door six times a day does 2,190 cycles a year (6 x 365), so a 10,000-cycle spring lasts about 4.6 years (10,000 divided by 2,190), while a busy one at ten cycles a day gets about 2.7 years (10,000 divided by 3,650). Every one of those is longer than a 12-month labour promise, so the two never collide, and a customer who read "worn, not faulty" with the rating on the invoice is less likely to feel cheated in year three. Offering a higher-cycle spring at a higher price turns the same clause into an upsell with a reason attached. Ratings vary by manufacturer, so print the rating of the spring you actually fit.
Add a claim route so customers know what to do and your team handles every claim the same way:
- The customer reports the problem in writing, with a photo if they can.
- The office checks the job record: date, work done, parts fitted and spring rating.
- A technician visits within your own target (say five working days) and decides whether the fault is covered.
- If it is covered the repair is free; if it isn't, the customer gets a quote first.

Spring and safety wording: what to record before you leave
Springs and cables are the parts that injure people, so this is where the contract earns its keep. Three things go in: what the customer must not do, what you test and record, and what happens when someone declines a safety repair. Keep the technical detail in the opener maker's manual and refer to it rather than copying it, because test methods differ by brand.
Customer duties come first. A short clause says the customer won't adjust, release or repair springs, cables or brackets, because those parts hold stored tension; will keep people, pets and vehicles clear while the door moves; and will test the door monthly as the opener manual describes. The International Door Association's care page recommends the same monthly routine, covering a visual check of springs, cables, rollers and pulleys, a balance test and a reversing test, and tells owners to call a trained technician when in doubt. Your clause can point to that routine without copying it.
Next, what you test before you leave. Record these checks on the job sheet and photograph the door open and closed:
| Check | How it is done | Note for the record |
|---|---|---|
| Balance | Opener disconnected, door lifted by hand: it should lift smoothly and stay open | If it drops, creeps up or takes real effort to lift, record it as out of balance |
| Safety reversal | A test object placed under the door as the opener maker's manual describes; the door must stop and reverse on contact | One maker's support page specifies an object 1.5 inches (3.8 cm) high or a 2x4 laid flat; follow the manual for the opener you fitted |
| Photo-eyes | Beam blocked while the door closes; the door must reverse | Check the small lights are steady and the lenses clean |
| Release handle | Handle disconnects the door, and it reconnects cleanly | Confirms the door can be moved by hand in a power cut |
| Cables, rollers, hinges | Visual check for fraying, wear and loose fittings | Photograph anything you flag |
The same support page says the reversal test must be repeated after repairs to the door, including springs and hardware, and after any opener adjustment, so a spring job always ends with the full set of checks. The completion record is a one-page list with a result, the technician's initials and the customer's initials for each check, plus the spring rating fitted. It takes about two minutes on a tablet. It is also the record most likely to help you if a claim is ever made, and it makes the monthly-testing clause concrete, because the customer has watched the test done.
Last, the clause for a repair the customer declines. Wording to start from, which the lawyer will adjust:
On [date] our technician found [issue] and recommended [repair]. We explained the risk of continuing to use the door in this condition. You have decided not to go ahead. Until it is repaired we have [left the opener disconnected / advised you not to use the opener]. Signed by the customer: [signature].
Ask the project for a second version covering doors your technician refuses to leave powered, such as an opener whose reversal test fails and can't be fixed on the day, and give technicians the right to stop work and leave the door safe and manual. Mark that clause [LAWYER] too, because a right to refuse or disable is the kind of term that needs local advice.
Liability and insurance: where AI drafts and the lawyer decides
Liability clauses are where AI is most useful as a drafter and most risky as an authority. It can explain a cap in plain words and offer variants, but it can't tell you what is allowed where you trade. Ask for three versions of the limit clause (light, standard and strict), each with a one-line plain-language reason, and take all three to the lawyer. Choosing between them is a legal judgement, and a lawyer who sees the alternatives can steer quickly.
Expect three AI habits, and fix each one:
- It overreaches. "We exclude all liability of any kind" is a common first draft. In many places some liability, such as for injury caused by negligence, can't be excluded or capped, and one-sided terms can be struck out. A sweeping exclusion can make the sensible clauses around it look less credible. Replace it with a cap and a short list of specific exclusions, and mark it [LAWYER].
- It borrows from elsewhere. Wording, thresholds and legal terms can come from places with different rules. The instruction never to cite statutes helps, but read every clause for terms you don't recognise.
- It ignores your insurance. State only the cover you hold, in words that match the policy, and ask your insurer whether the contract wording affects that cover. Don't write "fully insured" unless the certificate supports it.
Two clauses are specific to garage doors. The first covers items stored in the garage and vehicles parked under or near the door: customers clear the work area, and you aren't responsible for things left in it. The second covers pre-existing damage, where your before photos and inspection notes show what was already bent, rusted or misaligned. Business customers such as landlords and property managers may agree different caps and notice periods than homeowners, so tell the lawyer how many of your customers are which. The moving company contract tutorial works through a similar liability and cancellation split in another trade.
Payment, deposits and cancellation: tie each fee to a real cost
A fee a customer can understand is a fee they pay. Every charge in the cancellation clause should map to a cost you can name. Here is a sum for a special-order replacement door (illustrative figures). The door costs $1,800 to buy and the supplier charges 20% to cancel an order, which is $360. A 30% deposit is $540, so it covers the supplier's charge and leaves $180 towards the quoting and measuring time you wasted. A 10% deposit ($180) would leave you $180 short on every cancellation. That is how you pick the percentage, instead of copying a number from a template.
| Stage | If the customer cancels | What you keep | Cost it covers |
|---|---|---|---|
| Before anything is ordered | Free | Nothing | None incurred |
| Parts ordered, not delivered | Deposit kept up to the supplier's charge | Up to $360 in the example | Supplier cancellation charge |
| Delivered, work not started | Cost of goods you can't return, plus a fixed visit fee | Stock cost and the fee | Stock you can't resell |
| Technician on site, work not started | Call-out fee | A fixed fee close to 1.5 hours of technician time | A lost slot |
The other money clauses are short. Payment is due on completion. Late payment earns a reminder, and a fee or interest only if your lawyer confirms that is allowed where you trade. The quote states the call-out fee. A no-access rule helps as well: if the technician arrives at the agreed time and can't get in, the visit fee applies once you have tried to reach the customer.
One point to put to the lawyer by name: some places give consumers a cooling-off period for work agreed at their home, usually with an exception when the customer asks you to start urgent work straight away. A broken spring on a door that won't open with the car inside is exactly that case. Ask how to word the customer's request to start immediately, and what you may charge if they cancel afterwards. Don't let AI settle this one.
Handing the draft to a lawyer so the review stays short
A lawyer who receives a loose draft and a vague brief spends the first hour working out how you trade. Send the pack instead: the contract draft, the decision sheet, the AI's list of assumptions and questions, your suppliers' warranty documents, a sample quote and invoice, your insurance schedule, and two sentences on who your customers are (homeowners, landlords, property managers, and how many emergency call-outs you take). Ask for a fixed fee before you send anything, and ask for changes to be marked in the document so you can update the decision sheet to match.
Put these questions in the covering note:
- Which liability limits are valid for consumers where we trade, and which for business customers?
- What can't we exclude or cap at all?
- Does our deposit and cancellation wording fit consumer rules, including cooling-off periods for work agreed at the customer's home and the exception for urgent repairs?
- Can we charge a late-payment fee or interest, and how should it be worded?
- Is acceptance by tablet signature, email or text enough?
- Does our warranty wording create duties beyond the manufacturer's warranty?
- Does our insurance policy require particular contract wording or exclusions?
- How long should we keep the safety completion records?
When the reviewed version comes back, ask the project for two short documents: a one-page plain-language summary for customers and a field cheat-sheet for technicians. Update both whenever the contract changes, or they will drift apart. An example of the customer summary, for an illustrative firm:
- We do the work on your quote. If we find something else we'll tell you and ask first.
- Our workmanship is guaranteed for 12 months. Parts carry the manufacturer's warranty.
- Springs are rated by use, and the rating is on your invoice.
- We test the door's balance and safety reversal before we leave. Please test it monthly as your opener manual describes.
- Payment is due on completion. Special-order parts need a 30% deposit.
- You can cancel free before we order parts. After that we keep the costs we can't recover.
- Our liability is limited as set out in the full terms. [LAWYER: confirm how to state that this doesn't affect your legal rights.]
Then close the loop. Put a version number and a review date on the document, keep every version, and note on each job which version applied. Each quarter, count warranty callbacks and disputes. If the same argument keeps appearing, a clause is unclear, and the fix starts at the decision sheet, not at the model. Reread the tutorial on whether AI can review a contract when you want a second pair of eyes on a revision before it goes back to the lawyer.
Questions owners ask before they use AI for contract terms
Can I just use the AI draft without a lawyer?
No. AI can turn your decisions into clear wording, but it doesn't know the consumer rules, cooling-off periods or limits on liability that apply where you trade, and it can sound confident while being wrong. Use the draft to save a lawyer's time, send your open questions with it, and have the final version checked before customers sign it.
Should the warranty be measured in years or in spring cycles?
Use both. Give a fixed period for your workmanship, such as 12 months, because that is something you control. Describe spring life by the cycle rating of the part fitted, printed on the invoice, because wear depends on how often the door is used, not on the calendar. A busy household can reach a spring's rating in under three years.
Do I need a different contract for landlords and property managers?
Often yes. Business customers can usually agree different payment terms, liability caps and notice periods than homeowners, while consumers tend to get stronger statutory protection. Ask your lawyer whether one set of terms with a short business addendum is enough, or whether you want two documents. Tell the lawyer how many of your customers are businesses.
How often should the terms be reviewed?
At least once a year, and whenever you change suppliers, add a service, change your insurance or have a dispute that the terms didn't settle. Put a review date and a version number on the document, and keep old versions so you can show which terms applied to which job.
