As the bridge connecting our homes to the outside world, doors and windows are of paramount importance. Beyond their roles in wind and rain protection, thermal insulation, and soundproofing, they also play a critical part in ensuring our family’s safety. Therefore, when a new home is handed over, doors and windows should be carefully and regularly inspected and accepted. When inspecting doors and windows, keep the following points in mind.

1. Visual inspection of doors and windows

The surface quality of doors and windows in a franchise directly affects the overall decorative appearance of the wall after installation. Therefore, first inspect the gloss from a distance to check for any noticeable color variations; then examine closely and feel the surface with your hand to identify any scratches left by manual cutting. Next, verify that the glass is smooth and clean, confirm the presence of the national 3C certification mark, and check whether the insulated double‑glazed unit contains dust or condensation. Finally, pour water into the track to test the drainage holes, ensuring they are open and free of blockages.

2. Hardware Accessories Inspection

Hardware accessories are an essential component of the overall quality of doors and windows. The quality of these components directly affects the service life of the doors and windows. During acceptance inspection, the first step is to verify that all parts are fully installed and to check for signs of rust or damage.

Next, check whether the window and door sashes open and slide smoothly, and whether the locks engage and disengage with ease. Repeatedly open and close the sashes and operate the locks to see if they are too tight or too loose. If they are too loose, there may be a sealing issue. If they are too tight, the alignment of the frame and sash could be off, or components such as the locking points, pulleys, and sliding brackets may not be properly adjusted. If any problems are detected during inspection, contact the contractor promptly for corrective action.

3. Seal Strip Inspection

Sealing strips are a critical factor in determining the overall airtightness of doors and windows. The quality of these strips directly affects the degree of sealing. Therefore, they should not be overlooked during the acceptance inspection of doors and windows. We should inspect the rubber strips for cracks, aging, curling, or any grooves. The sealant must adhere tightly to the glass, with no visible gaps at the joints.

4. Visual Inspection of Doors and Windows

The installation of door and window frames directly affects the structural integrity of the doors and windows. Verify that the frames are secure, plumb, and tightly sealed; you can use a straightedge to check their flatness.

To check for air tightness, we should carefully inspect the exterior joints. If we find that the seams are missing sealant or that the waterproofing layer is damaged, we should promptly contact the contractor for repairs, as this not only compromises the airtightness of doors and windows but also allows rainwater to easily seep into the room through the damaged areas, damaging the interior finishes. Therefore, during the acceptance inspection, we must conduct a thorough check to prevent potential leaks.

5. Usage Inspection

The opening and operation of doors and windows constitute an essential step in their acceptance inspection. Verify that the doors and windows open and close smoothly. Simulate everyday usage by repeatedly opening and closing them to ensure proper functionality, and observe whether any unusual resistance or noise occurs during operation. Next, vary the force applied to the handles to confirm that the hardware can withstand different levels of exertion. If no issues are detected, the door and window acceptance process may be concluded.

By mastering these five key points, you’ll have no trouble with door and window acceptance during franchise operations. We must rigorously oversee the inspection and acceptance process; otherwise, it will be too late to regret any issues down the line. Therefore, we recommend choosing well‑established, reputable brands that guarantee quality.
