No matter who complains about leaking property on the external wall.

Legal analysis: the property department is generally entrusted by the developer to contact the maintenance affairs, and the property department should contact the construction unit for warranty. The developer has a contract with the construction unit, and the developer has the warranty of the construction unit, so as long as it is not the cause of abnormal use, the construction unit must guarantee the "house leakage". When the property department and the developer are not in charge, you can complain to the local "engineering quality supervision station" or the local "consumer association".

Legal basis: Article 26 of the Law of People's Republic of China (PRC) on the Protection of Consumers' Rights and Interests stipulates that when operators use standard clauses in business activities, they should draw consumers' attention to the quantity and quality, price or cost, time limit and method of performance, safety precautions and risk warning, after-sales service, civil liability and other matters related to consumers' major interests in a conspicuous way, and explain them according to consumers' requirements.
