What should be clarified before paying a deposit for whole-house customization?

Before paying a deposit, clarify whether the deposit is refundable and under what conditions it can be refunded; do not pay it blindly and get locked in. Next, ask about the measurement and re-measurement arrangements: on-site measurement is generally arranged within 1–7 days, and re-measurement is required after the water and electrical positioning is completed; the water supply and drainage for the sink, the gas socket, and the smoke exhaust path for the range hood must all be confirmed in advance. Also ask about the processing cycle, usually 15–45 days, which is affected by the board material, craftsmanship, and production scheduling; logistics generally take 1–3 days. Ask about prices by tier: for the basic kitchen cabinet configuration with E0 particle board cabinet body + PET door panel, Beijing is 900–1,000 yuan/linear metre, and in Baoding, Langfang, Xiong'an and Zhuozhou is 765–850 yuan/linear metre; mainstream ENF particle board in Beijing is 1,020–1,250 yuan/linear metre; upgraded ENF eco board in Beijing is 1,300–1,650 yuan/linear metre. The following are reference prices and do not constitute a formal quotation; the actual price must be calculated based on dimensions, design, materials, hardware, quantity, and on-site conditions.
