Door and window design must meet strict specifications, but during inspections, it's often found that some real estate properties fail to comply with these standards. This can lead to serious issues for homeowners during future decoration or daily life.
In the inspection room, problems with doors and windows continue to surface. From the initial design phase to construction and installation, various issues arise, which have become a common headache for many homeowners. If these problems are not identified and fixed in time, they can cause long-term inconvenience and even safety risks. Today, we’re sharing six commonly overlooked issues when checking doors and windows.
Design Issues
Doors and Windows Not Meeting Size Standards
Unreasonable early design can be very difficult to correct later, causing unnecessary trouble for homeowners. For example, door and window dimensions are strictly regulated by building codes, but many properties don’t follow these guidelines. In one case, Mr. Luo’s new home had a door that was only 76 cm wide, far below the required minimum of 90 cm according to the Residential Design Code.
Attention to Details During Inspection
Inspectors recommend that homeowners bring a measuring tape during the house inspection and measure door and window openings as needed. If any issues are found, they should immediately contact the developer for corrections.
No Drainage at the Bottom of Doors and Windows
A major design flaw observed last month is the absence of drainage at the bottom of doors and windows. This issue is widespread in many residential areas. If left unaddressed, rainwater can seep into the frames, leading to water damage and corrosion over time, shortening the lifespan of the doors and windows.
Inspectors remind homeowners that if this is not checked during the initial inspection, the problem may go unnoticed until after renovation. At that point, it becomes much harder to resolve. Homeowners should carefully examine every part of the property during the inspection and request immediate fixes from the developer.
Construction Issues
No Drip Line at the Top of Windows
Some door and window installations require specific construction details. For instance, a drip line should be installed on the outer edge of the window to prevent rainwater from flowing into the window sill or indoor walls. However, many properties lack this feature, leading to water leakage and potential mold growth over time.
Inspectors emphasize that leakage problems significantly impact both the aesthetics and functionality of a home. Doors and windows are common sources of leaks, so it's crucial for homeowners to thoroughly inspect their property before taking possession.
Leakage Sealant Between Door/Window Frame and Wall
According to the “Code for the Acceptance of Quality of Building Decoration Engineering,†the gap between metal door/window frames and walls must be properly sealed with sealant. However, many properties were found to have missing or incomplete sealant, leading to air leakage and potential water infiltration, which can damage interior finishes.
Inspectors advise that this issue is often overlooked during initial inspections. Once the renovation is complete, it becomes more complicated and costly to fix. Homeowners should ask the developer to reseal the gaps if necessary.
Installation Issues
Safety Glass Not Installed in Lower Window Sashes
For safety, certain regulations apply to window glass installation. According to the “Safety Management Regulations for Buildings,†safety glass must be used where the bottom edge of the glass is less than 50 cm from the finished floor. Many properties now have bay windows, but the glass under them often lacks the 3C certification, posing a serious safety risk.
Inspectors urge homeowners to check for the 3C logo under bay windows. If it’s missing, the developer must provide proof of safety certification. If not, the glass must be replaced immediately.
Deformation of Doors and Windows
Door and window deformation is a common issue found during inspections. Damaged frames, scratched doors, or misaligned sashes can result from poor installation or lack of protection during the process. These issues not only affect the appearance but also pose safety risks, such as doors and windows failing to close properly.
Inspectors recommend that even minor deformations should be addressed promptly. If ignored, the damage can worsen, affecting both the aesthetics and usability of the doors and windows.
