Use AI to draft clear warranty and guarantee letters that explain your work coverage to customers.

When you finish a job, customers often ask what's covered if something goes wrong. Writing a clear warranty or guarantee letter builds trust and prevents confusion later. Instead of scrambling to explain your coverage policy on the spot or sending a vague text, you can use AI to draft a professional letter that spells out exactly what you stand behind, for how long, and what's not included. 1. Open ChatGPT or Claude and describe the job you just completed and your standard warranty terms (e.g., "I just installed a new water heater. I offer a 1-year warranty on my labor. Parts are covered by manufacturer warranty. I don't cover damage from homeowner misuse or lack of maintenance."). 2. Ask AI to write a short, friendly warranty letter for the customer that explains what's covered, the time period, and any exclusions in plain language. 3. Review the draft and add any job-specific details — like the date of installation, the equipment model, or care instructions the customer should follow. 4. Copy the letter into an email or text, or print it to hand to the customer before you leave the job site. 5. Save the template in your phone notes or email drafts so you can quickly customize it for future jobs without starting from scratch. 6. Use the same approach to create guarantee letters for smaller jobs like drain clearing or fixture installs, adjusting the coverage period and terms to match the work you did.
