As the bridge connecting our homes to the outside world, the importance of doors and windows in door-and-window franchises is self-evident. Beyond their functions of windproofing, rainproofing, thermal insulation, and soundproofing, what’s even more crucial is that they ensure our family’s safety. Therefore, when a new home is being finalized, doors and windows should be carefully and regularly inspected and accepted. The following points should be noted during the acceptance inspection of doors and windows in door-and-window franchises.

1. Exterior inspection of doors and windows

The surface quality of doors and windows in a franchise system directly affects the overall decorative effect of the wall after installation. Therefore, first, view the doors and windows from a distance to assess their glossiness and check whether there are any noticeable color differences on the surface. Then, examine them closely by touch—run your hand over the surface—to see if there are any scratches caused by manual cutting. Next, inspect whether the glass surfaces of the doors and windows are smooth and clean, and verify the presence of the national 3C certification mark. Also, check whether the hollow sandwich layer contains dust or moisture vapor. Finally, pour water into the track to conduct a test, ensuring that the drainage holes are open and free of blockages.

2. Hardware Accessories Inspection

Hardware accessories are an important component of the overall quality of doors and windows. The quality of hardware accessories directly affects the service life of doors and windows. When inspecting hardware accessories, the first step is to check whether all components are properly installed and whether there are any issues such as rust or damage.

Next, check whether the window and door sashes open and slide smoothly and whether the locks open and close flexibly and effortlessly. Repeatedly open and close the window sashes and operate the locks to see if they’re too tight or too loose. If they’re too loose, there might be an issue with the seals. If they’re too tight, there could be a problem with the alignment of the window frame and sash, or the locking mechanisms, pulleys, sliding brackets, and other components may not have been properly adjusted. If you identify any issues during the inspection, promptly contact the merchant for rectification.

3. Seal Strip Inspection

The sealing strip is a crucial factor determining the overall airtightness of doors and windows. The quality of the sealing strip directly affects how well the doors and windows seal. Therefore, we must not overlook it during the acceptance inspection of doors and windows. We should check whether the rubber strip is broken, aged, curled, or has any grooves. The sealing tape must be fully and tightly adhered to the glass, and there should be no noticeable gaps at the joints.

4. Exterior inspection of doors and windows

The installation of door and window frames directly affects the structural integrity of doors and windows. Check whether the door and window frames are sturdy, level, and tightly sealed. We can use a plumb line to directly verify the flatness of the door and window frames.

To check for sealing integrity, we should carefully inspect the outdoor connections. If we find that seams lack sealant or the waterproof layer is damaged, we should immediately contact the supplier for repairs, as this not only affects the airtightness of doors and windows but also allows rainwater to easily seep into the room through the damaged areas during rainfall, potentially damaging the interior décor. Therefore, during the acceptance process, we must conduct a thorough inspection to prevent potential leaks.

5. Inspection Usage

Opening and using doors and windows is an essential step in the acceptance inspection of doors and windows. Check whether the doors and windows open and close smoothly. Simulate everyday use by repeatedly opening and closing the doors and windows to verify that they function properly. Observe carefully during the opening and closing process for any unusual resistance or noises. Then, vary the force applied when opening and closing to determine whether the doors and windows can withstand different levels of pressure. If no issues are detected, the acceptance inspection of the doors and windows can be considered complete.

By mastering these five points, you’ll have no trouble with the acceptance inspection of doors and windows when joining a franchise. We must strictly control the acceptance process for doors and windows; otherwise, it’ll be too late to regret any issues that arise later on. Therefore, I recommend choosing well-established, big brands that guarantee quality.
