What is the warranty period? How does Yichen handle after-sales service and spare parts?

Yichen provides a 12-month warranty on major structural components, covering the steel frame, sandwich panels, and doors and windows. This is complemented by lifetime technical support, meaning clients can access Yichen’s technical team for guidance throughout the operational life of the building.

For after-sales inquiries involving damage or malfunction, Yichen commits to responding within 24 hours. Minor issues are typically resolved through remote technical guidance; for more significant problems, Yichen can dispatch replacement components or arrange on-site repair as required. Spare parts for ongoing maintenance are available to clients at factory cost price, with fast shipping arrangements in place to minimize project downtime. To submit a warranty claim or enquire about spare parts for a Yichen Prefab House, contact the after-sales team.
