Key takeaways
- A guarantee is a promise customers will hold you to, so write it in plain words, with its limits stated clearly and prominently[1].
- FTC guides say terms like 'Satisfaction Guarantee' or 'Money Back Guarantee' should be used only if you refund the full purchase price when the customer asks[1]; a 'we'll make it right' promise is safer for most trades.
- Customers are stretched: only 63% of adults would cover a $400 emergency expense entirely with cash or its equivalent[2], so a clear guarantee lowers the risk of saying yes.
- Log every claim and its cost; a guarantee that costs well under the value of the trust it creates is worth keeping.
Why guarantees work for home services
Hiring a contractor is a leap of faith. The homeowner lets a stranger into the house, agrees to a price for work they cannot easily judge and pays before knowing whether the fix will last. A guarantee shifts some of that risk back to the company, and that makes it easier for the customer to say yes.
Money is often the sticking point. The Federal Reserve's 2025 household survey found that 63% of US adults would cover a $400 emergency expense completely with cash or its equivalent[2], which means more than a third would need to borrow, sell something or could not pay. In Angi's 2025 survey, 56% of homeowners faced budget issues on maintenance projects[3]. For a customer in that position, knowing what happens if the repair fails is a real part of the decision.

A guarantee also disciplines the business. When every failed repair costs a return visit, technicians and managers pay closer attention to diagnosis, parts and testing. The guarantee becomes a quality system as well as a marketing line.
What the FTC expects from guarantee claims
The FTC's Guides for the Advertising of Warranties and Guarantees address satisfaction claims directly. They say a seller should use terms such as 'Satisfaction Guarantee', 'Money Back Guarantee' or 'Free Trial Offer' only if it refunds the full purchase price of the advertised product at the purchaser's request[1]. They also say an advertisement that mentions such a guarantee should clearly and prominently disclose any material limitations or conditions[1].
The guides are written mainly with products in mind, and state consumer protection laws add their own rules, so check your wording with an attorney. The practical lesson is simple: do not say 'money back' unless you mean it, and do not hide the conditions in fine print. State laws may also require specific contract wording for home improvement work. This article is general information, not legal advice.
Types of guarantees and when each fits
| Guarantee | What you promise | Fits best |
|---|---|---|
| Make-it-right | If you are not satisfied, we come back and fix it at no charge | Most repair and service trades |
| Re-service | If pests or problems return within the service period, we re-treat at no charge | Pest control, lawn treatments |
| Re-clean | Tell us within 24 hours and we re-clean the missed areas | House cleaning |
| Money back | Full refund of the service price on request, within stated limits | Low-ticket, low-risk services where you can afford it |
| On-time | A stated credit if we arrive outside the window without notice | Companies with strong dispatch discipline |
| Workmanship warranty | Labor is covered for a set period | Installs and larger repairs; see the warranty guide |
Most companies are best served by a make-it-right promise for service work, a trade-specific re-service promise where the work has a natural follow-up, and a separate written workmanship warranty for installs. Money-back promises can be powerful for small, repeatable services, but they need a budget and a clear definition.
Writing the wording
Good guarantee wording is short enough to fit on an invoice and specific enough that a customer and a manager would read it the same way. It names what is covered, how long the customer has to tell you, what you will do, and the main limits.
Make-it-right wording: 'If you are not satisfied with our work, tell us within 30 days and we will return to make it right at no charge for labor. This covers the work we performed. It does not cover new problems, parts we did not supply, or work changed by others.' (Example)
Re-clean wording: 'If we missed something, tell us within 24 hours of your clean and we will come back to re-clean those areas at no charge.' (Example)
- Use the same wording on the website, the estimate, the invoice and the booking script.
- State the time limit in days, not 'a reasonable time'.
- Say what you will do: return, re-service, re-clean, credit or refund.
- List the main exclusions in one sentence.
- Ask customers to contact you before hiring someone else to fix the same problem, and say so in the wording.
- Do not tie the guarantee to reviews in any way. FTC guidance says a business cannot make an incentive conditional on a review being positive[4].
Limits that are fair, not sneaky
Every guarantee needs limits, or a few customers will use it to get free work. But limits that feel like traps destroy the trust the guarantee was supposed to build. A good test is whether you would be comfortable reading the limit out loud to the customer before the job starts.
- Fair: a stated claim window, access to inspect before any refund, coverage limited to the work you did, and exclusion of damage caused by misuse or by others.
- Fair: requiring the customer to follow care instructions you gave in writing, such as keeping pets off a treated lawn for a set time.
- Unfair: 'satisfaction guaranteed' with a policy that refunds nothing.
- Unfair: conditions mentioned only after the customer complains.
- Unfair: requiring customers to sign away the right to post a review in exchange for a refund.
Honoring claims consistently
Take the claim seriously
Log it as a complaint, acknowledge it within your response target and name the person handling it.
Inspect before deciding
Send a senior technician or supervisor to see the problem, with photos from the original job if you have them.
Apply the written terms
If the claim is covered, do what the guarantee says without haggling. If it is not, explain why with reference to the wording and offer a written price for any new work.
Confirm the outcome
Send a short written summary of what was done and close the case after a check-in call.
Record the cost
Labor hours, parts and any refunds, tagged by service, technician and cause.
Give managers room for judgment at the edges. A customer who calls on day 33 of a 30-day guarantee with a reasonable claim usually deserves the benefit of the doubt. The written terms protect you from abuse; they are not a reason to be rigid with honest customers.
Teaching the team to talk about it
A guarantee nobody mentions does little to win jobs, and a guarantee everyone describes differently creates disputes. Give the team one short way to explain it at each stage.
- On the booking call: 'All our service work comes with a 30-day make-it-right promise. If you're not happy with the work, we come back at no labor charge.' (Example)
- When presenting options: the technician repeats the promise and points to where it is printed on the estimate.
- At the end of the job: the technician mentions it again with the invoice, together with how to reach the office.
- When a customer complains: staff refer to the written wording, not to memory, and never promise more than it says without a manager's approval.
Role-play the hard version too: a customer who wants a full refund for a job that was done correctly but did not meet an expectation nobody discussed. The answer is usually empathy, a look at what was agreed, and an offer that fits the written terms. Teams that have practiced this conversation stay calm when it happens for real.
Tracking what the guarantee costs
Example: a fictional pest control company with a re-service guarantee records 62 re-service visits in a quarter across 1,900 completed treatments, about 3.3% of jobs. The labor and product cost of those visits is about 1.5% of the quarter's revenue. Most re-services trace to two causes: treatments done in heavy rain and missed entry points in garages. The company changes its rain policy and adds a garage checklist, and the re-service rate falls the next quarter.
- Claims per 100 jobs, by service line.
- Cost of claims as a share of revenue.
- Top causes and the change made for each.
- Repeat bookings from customers who used the guarantee.
The last line is the one owners forget. A customer whose problem was fixed quickly under a guarantee often becomes more loyal than one who never had a problem. Connect this tracking to your complaint resolution process and your workmanship warranty terms so that promises, claims and fixes are all recorded in one place.
Frequently asked questions
Should a contractor offer a money-back guarantee?
Only if you are prepared to refund the full price on request. FTC guides say money-back and satisfaction guarantee terms should be used only when the full purchase price is refunded at the buyer's request. A make-it-right promise suits most trades better.
What should a satisfaction guarantee include?
What is covered, the time limit to claim, what you will do (return, re-service, credit or refund), the main exclusions, and a request that customers contact you before hiring someone else.
Can I limit my guarantee?
Yes, but disclose material limits clearly and prominently wherever you advertise the guarantee, and apply them consistently.
How do I stop customers abusing a guarantee?
Inspect before deciding, apply written terms, and track claims by customer. Abuse is rare; most claims point to a fixable problem in your process.
