Can I refuse to pay the property fee if the external wall leaks? What should I do?

If the house leaks, you can't refuse to pay the property management fee, and the property company can sue. The relationship between the property company and the owner is a contractual relationship. The owner entrusts the property to repair, maintain and manage the house, supporting facilities, equipment and related sites, and maintain the environmental sanitation and order in the relevant areas. The rights and obligations of both parties are stipulated in the contract. If there is any dispute, it can be solved through legal channels.
