How do I ask a repair provider for a written diagnosis and work summary?
Quick answer
Ask the provider to document your reported problem, what they found, and what work they completed or recommend. Request an estimate before proposed work and an itemized work summary afterward, if those records are available. For auto repairs, FTC guidance says a written estimate should identify the condition, needed parts, and anticipated labor charges, and a completed repair order should describe work, parts, costs, and odometer readings [S1]. That guidance does not establish requirements for other repair types.
The question, the details, the next step.
A practical checklist
Describe the symptom or issue briefly, without assuming its cause.
Ask what written estimate and completed-work records the provider can supply.
Request findings separately from proposed or completed work.
Check that listed parts, labor, and charges are understandable and connected to the work.
Ask for unclear or unavailable details to be explained, and keep the written response.
A few more useful answers
Should I ask the provider to guarantee the diagnosis?
Ask them to explain the basis for their findings and note any uncertainty. This request is for a clear record, not a guarantee that the diagnosis or proposed work will resolve the issue.
Does the auto-repair guidance apply to every repair provider?
No. The cited FTC guidance is specific to auto repair. For other products or services, ask what records the provider offers; the source does not establish documentation requirements for them.
What if the provider gives me only a verbal explanation?
Ask whether they can provide a written estimate, invoice, service note, or other available record. If they cannot, you can write down what was explained and ask them to confirm or correct your summary.
