The design of doors and windows has strict requirements in the specifications, but in the process of house inspection, it was found that the doors and windows of some buildings were not designed according to the requirements, leaving difficulties for the owners in their later decoration or life.
In the inspection of houses, the problems of doors and windows are constantly emerging. There are various defects in design, construction and installation details, which have become the common problems faced by house owners. If these problems are not found and rectified in time, they will bring troubles to the owners for future use. Today's editorial summarizes six hot issues that are easy to ignore when accepting doors and windows for owners.
Windows and doors are out of specification
The design in the early stage is unreasonable, and it is often difficult to rectify in the later stage, which will also bring inconvenience to the owner's life in the future. For example, the design of doors and windows has strict requirements in the specifications, but during the house inspection, it was found that the doors and windows of some buildings were not designed according to the requirements, leaving difficulties for the owners in the later decoration or life. For instance, the door opening of Mr. Luo's new house is too narrow, with a width of only 76 centimeters, which does not conform to the stipulation of "Residential Design Code" that the minimum width of the door opening is 90 centimeters.
Relevant Details to Be Noticed in Acceptance of Doors and Windows
Home inspector reminded: When the owner inspects the house, he should take a tape measure and measure whether the size of the door opening and the window are consistent at any time. Once any design problem is found, he should find the developer to take remedial measures in time.
Door and window bottom frame has no drain
Last month's inspection showed that another outstanding design defect was that the bottom frame of doors and windows was not provided with a drain, which appeared in many buildings. If it is not found and rectified in time, when it rains, rainwater seeps into the bottom frame of doors and windows and cannot be discharged in time, resulting in accumulated water corroding the door and window frames and shortening the service life of the doors and windows.
Home inspector reminded: If the owner does not check during the house inspection, the installation problem will be left to the owner, and the problem will not be discovered until the decoration is moved in. Who will he go to then? Therefore, the owner should carefully check every part of the house during the inspection, and ask the developer to rectify any problems found in time.
There is no drip line at the top of the window.
Some parts of doors and windows have special construction requirements and must be constructed in place according to regulations. For example, at the outer edge of the window, it is required to properly prepare the drip line to prevent rainwater from flowing into the window sill or indoor wall surface. However, in the process of house inspection in home inspector, it was found that many buildings did not do drip line according to the requirements due to the window edge, resulting in the occurrence of water seepage. If it is not rectified in time, when it rains in the future, the rain will still follow the window edge indoors, and it is inevitable that the wall will become damp, moldy and hairy over time.
Home inspector reminded: The problem of leakage has a great impact on the decoration and future life of the house. Doors and windows are also one of the sources of leakage in the house. Owners must carefully inspect the house when accepting the house, leaving no hidden danger of leakage.
Leaking sealant between door window frame and wall body
According to the Code for Quality Acceptance of Building Decoration Engineering, the gaps between metal door and window frames and walls shall be filled and filled and sealed with sealant. However, home inspector found that the doors and windows of many buildings were either leaking sealant or the sealant was incomplete. This not only affects the closeness of doors and windows, but also when it rains, rainwater easily seeps into the first net of interior decoration and damages the interior decoration.
Home inspector reminds: Owners of such problems are often easily ignored when purchasing houses. Only after the renovation and occupancy can they find that the trouble is big and they must ask developers to refill the sealant.
The lower frame of the sash is not equipped with safety glass.
For safety reasons, there are also hard and fast regulations on the installation of window glass. According to the Regulations on the Administration of Building Safety Glass, safety glass must be used for glass whose bottom edge is less than 50cm from the final decoration surface. Nowadays, many apartments are designed with floating windows, but it is difficult to find 3C logo on the fixed fan glass under the floating windows, which is not safety glass and has potential safety hazards.
Home inspector reminded: Door and window glass is related to personal safety. If the owner cannot see the 3C logo on the fixed door glass under the floating window, he must require the developer to show the certificate or the inspection certificate for materials entering the factory. If it cannot be proved to be safety glass, it must be replaced.
Deformation of doors and windows
Deformation of doors and windows is a common problem in the July inspection. For example, the window frame was hit and sunken, the door frame was damaged, the door leaf was scratched, etc., which were all caused by careless workers in the installation process, or due to negligence in the protection of finished products during the installation. If these problems are minor, they will affect the aesthetic appearance; if they are serious, the doors and windows cannot be closed and there are potential safety hazards.
Home inspector reminded: Windows and doors should be repaired in time even if there is slight deformation. Otherwise, over time, the deformation will worsen, which will not only affect the appearance, but also cause problems in the use of windows and doors.
