Where can I complain about the housing quality in Xi 'an?

1. Where can I complain about the quality of the house in Xi 'an? Housing quality problems can be complained to the engineering quality supervision department under the local construction Committee. In addition, different housing quality problems have different acceptance channels. For example, if there is a problem with the house outside the warranty period, the public can report it to the property company where it is located; For another example, if the public finds that the second renovation of the neighbor's house has damaged the building structure and caused water seepage downstairs, they can complain to the decoration management department; If citizens have questions about building materials such as security doors and security window, they can complain to the Bureau of Quality and Technical Supervision; If citizens encounter contract breach such as the delay in the delivery date, they can solve it through the real estate management department and the industrial and commercial administration department or through litigation; If citizens find that the landscape, greening and roads in the community are not implemented according to the design drawings and publicity materials, they can complain to the real estate development management department. Second, common housing quality problems 1, building instability. Explain that it is still sinking after the settlement period; Uneven settlement causes buildings to tilt; The overall strength is not enough, and the building shakes after shaking or in strong wind; Due to the imperfect structure, some or all of the load-bearing systems are under-loaded, which leads to the hidden danger of partial or total collapse of the building. 2. cracks. Include wall cracks and floor cracks. Cracks are divided into strength cracks, settlement cracks, temperature cracks and deformation cracks, which are caused by insufficient material strength, uneven stress on structures and walls, insufficient tensile and collapse strength, uneven settlement of buildings, inferior building materials and insufficient drying after masonry. 3. Leak. Due to the imperfect waterproof technology and poor quality of waterproof materials, roof leakage, horizontal leakage in kitchen and bathroom, vertical leakage downstairs, vertical leakage is more common in the joints of various pipes and floors. In rainy season and when the water consumption of kitchen and bathroom is large, serious leakage will affect the normal life of users, destroy the ground decoration and affect the neighborhood relationship upstairs and downstairs. 4, metope empty drum, wall peeling. The poor connection between the building blocks in the wall and the interlayer leads to cavities under the action of pressure and temperature difference, which reduces the overall compressive capacity of the wall and makes the surface paint layer easy to fall off. Sometimes, under the condition of not hollowing out, the quality of wall painting materials is poor and the painting process is not in place, which will lead to a large area of wall skin falling off. 5, sound insulation, heat insulation effect is poor. The partition walls and floors in residential buildings have poor sound insulation and shock absorption effects, which can not meet the requirements of privacy; The roof and external wall cool down quickly in winter and heat up quickly in summer, which can't meet the requirements of thermal insulation. The reason for the above phenomenon is that the thickness of sound insulation materials for walls and roofs is not enough, the quality of materials is poor, or the construction technology does not meet the requirements. 6. Doors and windows are poorly sealed and deformed. Some doors and windows were installed later, and some problems such as poor sealing, local materials or overall deformation occurred after a period of use. In severe cases, it is impossible to block the line of sight and shelter from the wind and rain, and some cannot be closed and opened. The reasons for the above problems are that the quality of the selected materials is not good, the wood is not dry enough, or it is attacked by moisture after installation and the workmanship is rough. Generally, the quality problems of doors and windows are not harmful, and only local maintenance or replacement is needed. 7. Run up and down the water. Leakage wastes resources and affects people's normal life. The reason is that the horizontal and vertical design of water supply and drainage pipeline is not reasonable enough, and the quality of faucet and toilet is not up to standard. Generally speaking, when citizens choose housing quality complaint institutions, they should combine the reasons of housing quality, which are generally similar to serious problems such as cracks and leakage in houses. That shows that the houses sold by developers have certain quality problems in essence, and the local construction quality supervision departments should pay attention to these problems and start to deal with them. There are still some drawbacks in the supervision of housing quality problems.
