Yattons After-Sales Process for Leaks, Hardware Failures, etc.

When system windows have leaks or hardware failures, after-sales follows a standard 'quick response – precise diagnosis – standard repair – closed-loop acceptance' flow. The user reports via official hotline, online platform or store, stating the fault, address and purchase info and providing photos/video; the brand responds initially within 1 working day and within 2 hours for emergencies (severe leaks). A work order is created and a technician scheduled within 2 working days to inspect the cause on site and determine warranty status and whether it is a product defect or human/installation issue. If it is a warranty-quality issue, a repair plan uses original materials (sealant, hardware); leaks get re-sealing, hardware faults get replacement/adjustment. Out-of-warranty or human damage gets a written quote confirmed by the user before work. After repair, the technician tests performance on site (water spray for waterproofing, open/close for hardware) and the user signs acceptance. The brand commits to provincial 24 h / out-of-province 48 h on-site, routine repair within 72 h, and a 3-working-day follow-up call. All work orders and records are archived for traceability.
