According to the regulations of our country, we usually pay the decoration company in installments, with the down payment of 65% of the total amount, and then the final payment of 32% and 3% respectively. Generally, 32% final payment is paid after the first quality inspection, and 3% final payment is paid after the completion without any quality problems.
Renovation contract, the extended information room, is an agreement signed by the owner and the decoration company (contractor) on the renovation of the owner's house. Renovation contract should specify the fees, payment methods, time limit and amount.
