How to handle a customer who wants a written guarantee
Put only what you can honor in writing, in plain words.
- Separate warranty from promises. Say what is covered, for how long and what is not covered.
- Write it on the quote. Keep the wording on the same document the customer signs.
- Name the exclusions. Customer misuse, outside damage and normal wear are common examples.
- Say how to claim. Give a phone number or email and what you need, such as photos and the job date.
- Keep a copy on the job. You and the customer should hold the same version.
Common questions
Should I guarantee results?
Only if you can control the result. Guarantee your workmanship and name the parts warranty from the maker.
Do laws set a minimum?
Rules differ by state and trade. Verify with your attorney.
