Door and window installation is an important part of building or renovating a house. In addition to protecting the house from the weather and increasing safety, it also plays a role in enhancing the beauty and comfort of living. Therefore, professionally checking the door and window installation is necessary to ensure that the installation is up to good standards and of high quality. The following are the inspection steps that should be followed:

1. Check the frame installation neatness The door and window frames should be installed firmly, without distortion or tilt. Check the frame level with a laser tool to measure the verticality and level to ensure that the frame is installed in the correct plane. Check the gaps around the frame to ensure that they are sealed with waterproof and windproof materials, such as high-quality silicone.
2. Check for smooth opening and closing Doors and windows should be able to open and close easily without obstruction. Check the hinge and sliding mechanisms to ensure that they are installed correctly and that there are no noises or friction during use. For sliding or folding windows, check that the locks and other mechanisms are functioning properly.
3. Check the locking and safety system The door and window locking system should function properly. Locks securely without looseness If it is a multipoint lock system, test locking and unlocking at every point to ensure that the system works properly. Check safety, such as installing knobs or handles securely, with no loose or loose parts.
4. Check water and wind resistance Test that windows and doors can prevent water leakage by spraying water to simulate rain. Check the seals around the door and window frames for gaps that wind can pass through to increase comfort and reduce energy costs from using air conditioners.
5. Check the quality of the materials Check that there are no cracks, scratches or damages on the frames and glass panels. If it is wood, check that the wood coating is smooth, with no loose or swollen spots. If it is aluminum or UPVC, check that the color is even and there are no stains.
6. Check the glass installation The glass should be installed securely, with no gaps or movement. Check that the glass has no cracks, scratches or air bubbles in the case of double-glazed glass. Test the strength of the glass by looking at the standards used, such as safety glass or soundproof glass.
7. Check the connection to the wall
   The frame of the door and window should be tightly attached to the wall without gaps.
   Check that the edges of the frame and the wall are sealed with suitable materials, such as silicone sealant or PU foam, to prevent water and air leaks.
8. Check the overall aesthetics.
   Check that the installation has no stains or excess silicone.
   Check that the corners of the door and window are neat and have no obvious seams.
   All colors and materials should be consistent and suitable for the interior decoration of the house.
9. Test it out for real use.
   Test the use of the door and window in everyday life, such as opening and closing in different directions, locking, and using other additional functions.
   Check if there are any problems that may occur during actual use, such as inconvenience in opening and closing.
10. Check the warranty and maintenance instructions.
    Ask for a warranty from a technician or dealer to ensure that in case of problems, you can claim it.
    Get advice on maintenance, such as cleaning, lubricating hinges, or maintaining the lock system.
