Second, material inspection should not be perfunctory. After unpacking, carefully check whether the door frame, door leaf, and hardware are complete, and whether the surface has scratches or deformation. Pay special attention to checking if the sealing strip is intact. Inferior sealing strips not only have poor sound insulation but may also emit pungent odors at high temperatures. In addition, communicate the installation time with the property management in advance to avoid the peak renovation period and prevent neighborhood conflicts caused by handling noise.
Completion of installation does not mean everything is settled— the acceptance process is the final guarantee of quality. First, check whether the door opens and closes smoothly. Open and close the door from different angles to observe if there is abnormal noise or resistance. Second, use a strong flashlight to shine on the gap between the door frame and the wall to ensure that the sealant is applied evenly without missing areas or bubbles.
Safety performance testing is also essential. Push the door frame forcefully to check its stability; try to violently open the lock from the outside to confirm that the anti-theft function is normal. Finally, don’t forget to request the installation warranty card. The installation service warranty period of regular manufacturers is usually 1-3 years, which is an important voucher for later maintenance.
