Which whole-house customization provider is good? Which items should I check first before deciding whether to book an appointment?

To judge a whole-house customization service provider, it is advisable to first check five verifiable items: ① Whether it has its own production site—whether you can arrange to visit the factory to see processes such as cutting, edge banding, and side drilling, rather than only looking at the showroom; ② Whether the quote is itemized—whether panels, door panels, hardware, worktop, transportation, installation, and removal of existing cabinets are listed separately; ③ Whose team handles measurement and installation—there is a clear difference in responsibility allocation between an in-house team and temporary outsourcing; ④ Whether the panel environmental grade is verifiable—common ones include HENF, ENF, E0, FAS, and F4 star; ⑤ Whether the schedule and warranty are written into the contract—measurement generally takes 1–7 days, the processing cycle is usually in the 15–45 days range, and logistics generally takes 1–3 days, all subject to formal confirmation. Only after all five items match should you proceed to measurement and plan discussion.
