Window and Door Brand Ranking: Let’s Talk About the Key Points for Acceptance Inspection of Window and Door Projects

　　1. Visual inspection of doors and windows

　　The quality of the surface finish of doors and windows directly affects the decorative appearance of the entire wall during installation. Therefore, first we should take a broad view to assess the smoothness of the doors and windows, checking whether there are any obvious color inconsistencies on their surfaces. Upon closer inspection and by gently touching them with our hands, we should also verify whether the surface has any scratches that might feel rough to the touch.

　　Next, check whether the surfaces of door and window materials are smooth and clean, and whether they bear the Chinese 3C certification mark. Also, verify that the hollow cavity is free of dust, water vapor, and other contaminants. We can then proceed to add water into the track for testing, checking whether the vent holes are properly connected and free of blockages.

　　2. Inspection of hardware accessories

　　Hardware accessories are crucial to the overall quality of doors and windows; the quality of these accessories directly affects the service life of the doors and windows. For the engineering acceptance of hardware accessories, we must first inspect whether they are fully assembled and check for issues such as rust or damage.

　　Next, check whether the window and door sashes open and slide smoothly, and whether the hardware locks open and close flexibly and without obstruction. Continuously open and close the window sashes and operate the hardware locks to see if they’re too tight or too loose. If they’re too loose, it could indicate a potential issue with the seal’s integrity; if they’re too tight, it might suggest that the window sash isn’t properly leveled, or that components such as lock latches, rollers, or slide supports haven’t been adjusted in a timely manner. If you identify any problems during inspection, be sure to contact the seller promptly for necessary repairs.

　　3. Rubber strip inspection

　　The rubber seal strip is a key factor in determining the overall air-tightness of doors and windows; the quality of the rubber seal strip directly affects the sealing performance of these openings. Therefore, during the acceptance inspection of door and window projects, this aspect should not be overlooked. It’s essential to check for issues such as cracks, aging, curling, or detachment from the groove in the seal strip. Moreover, the seal strip must be tightly pressed against the glass pane throughout its entire length, and there should be no noticeable gaps at the joints.

　　4. Inspection of door and window frames

　　The quality of the window and door frame assembly directly affects the structural integrity of the windows and doors. The window and door frames can be subjected to safety inspections based on their flatness and sealing performance. We can use vertical measuring tools to thoroughly check the flatness of the window and door frames.

　　For the tightness and sealing inspection, everyone needs to carefully examine the outdoor joints. If you find that sealant has not been applied properly at the joints or that the floor waterproofing has been damaged, you should immediately contact the seller for remedial action. This is because such issues can severely compromise the airtightness of doors and windows. As soon as it rains, moisture is likely to seep into the room through these damaged areas, causing damage to the interior decoration. Therefore, during project acceptance, it is absolutely essential to conduct a meticulous inspection, leaving no hidden leakage risks behind.

　　5. Application Status Verification

　　Once the doors and windows are opened and put into use, it’s time to proceed to the acceptance inspection of the door and window installation. At this stage, you need to check whether the opening and closing of the doors and windows is smooth and stable.

　　Simulate the daily use of doors and windows by repeatedly opening and closing them, checking for any issues in their operation. During the opening and closing process, observe whether the doors and windows experience abnormal friction or make unusual noises. Then, adjust the range of motion and verify whether the doors and windows can withstand different opening and closing amplitudes. If no problems are detected, the doors and windows can proceed to acceptance inspection.
