Do high-rise windows leak property management?

The leaking property of high-rise windows will be managed, but it depends on public areas, such as balconies, roofs and walls. , does not belong to the maintenance scope of the property company. If the building leaks due to improper use of the owner's own parts, such as waterproofing and illegal decoration, etc. , the owner should bear the responsibility. There is also the problem of building quality, and you can claim compensation from the developer.

What are the reasons for the leakage of exterior doors and windows of high-rise residential buildings?

1. design: In order to satisfy the developer's overall aesthetic effect, the design unit unilaterally pursues the change of concave-convex shape in the facade design, resulting in the ratio of convex window and corner window exceeding 60%, and the ratio of north and south wall windows >:1:1,which increases the difficulty of civil construction, installation of external wall windows and leakage prevention to varying degrees, leaving a hidden danger of leakage.

2. Manufacture and installation of doors and windows: The manufacturing accuracy of external doors and windows can't meet the quality requirements, and the assembly parts after bonding are not filled with sealing materials, which is an important reason why rainwater easily penetrates into doors and windows through various assembly gaps. When doors and windows are installed on site, the following situations will also lead to leakage: due to poor control of assembly size, the lap seal position is misplaced or the lap size is insufficient, or cracks are generated due to insufficient pressure. Fastening screws used to fix door and window frames are not sealed with sealant, or the surface of sealing parts is not cleaned when sealing. After the glass was installed, the waterproof sealant between the glass and the door and window frame was not filled in. In addition, the traditional "pre-installed" installation process is adopted for exterior doors and windows. Before the end of civil construction, the door and window frames are directly installed on the pores, and the gap between the window frame and the edge of the window hole is not equal, which increases the difficulty of gap filling in the next working procedure. The main reasons for the leakage of external doors and windows are that the gap is too small to be filled with materials and the gap is too large to fix the doors and windows.

3. Material: The specifications, varieties and materials of external doors and windows (including supporting hardware and filling sealing materials) are directly related to the leakage of external doors and windows.

4. Civil construction: First, the openings of doors and windows are not designed according to the design requirements, resulting in different sizes of gaps between window frames and openings; Second, the concrete waterstop of the windowsill was not poured according to the design and specification requirements, and the brick exterior wall was reinforced with concrete reinforcement frame of the outer window; Third, the proportion and filling time of mortar were not adjusted according to temperature change, gap size and other factors; Fourth, the concrete roof of the bay window is not vibrated properly. After the suspended ceiling with bay window is installed, rainwater seeps through the telescopic rod that fixes the suspended ceiling, resulting in moldy suspended ceiling.
