What should I do if I install my own house and the property needs decoration company information or something?

Explain to the property company that you are looking for workers to decorate directly, not a decoration company. This kind of operation is very common, and the property will have a corresponding process. The property wants to charge more. With money, he can say anything. You need to pay more for the company, and you can pay less for your installation. There is also a property that wants to talk to your decoration company about some precautions and garbage disposal points.
