1. What should you do if the door or window sash is sagging?
(1) Adjust the stay rod or lower pivot.
(2) Reinstall the glass and adjust the shims.
2. What should you do if the mesh surface of your screen door or window is damaged?
Carefully remove the rubber covering the mesh surface, take out the damaged mesh, cut a new piece of mesh to the appropriate size, and carefully place it into the mesh frame groove. Then, secure it using an embedded fixing method: simply align the natural ridges and grooves of the rubber with the corresponding features of the frame to achieve a snug, stable fit.
3. What should you do about condensation forming on the glass?
Glass condensation is mainly caused by poor circulation of warm air, so it’s necessary to improve indoor air exchange. For example, if a heater is blocked beneath the windowsill—especially when the sill is wide—the lower part of the window glass is prone to condensation. To solve this issue, you can drill a few small holes in the windowsill, allowing warm air to flow directly toward the glass from within the openings.
4. What should you do if the locking mechanism with a built-in handle feels stiff when tightening, doesn’t lock securely, or the key doesn’t fully engage in the lock?
Try pulling the handle again. If you still can't resolve the issue, please contact your local service provider.
5. What should I do if water is leaking inward from the top of the window frame?
(1) Open the window sash and drain hole cover, remove any obstructions, and then pour water into the drain hole to check whether it flows smoothly outdoors, confirming that drainage is working properly.
(2) Check if the seal is deformed or damaged, and replace the seal if necessary.
6. What should you do if water is seeping outward at the junction between the wall and the window sill frame?
(1) Determine whether the water intrusion into the room is caused by cracks in the waterproof sealant or by a reversed slope of the windowsill.
(2) If the sealant has cracked, reapply it at the inner and outer sealing points where the windowsill meets the lower frame.
(3) If the windowsill slope is higher on the outside and lower on the inside, the exterior windowsill needs to be renovated to ensure no water accumulates at the sill.
7. What should I do if water is seeping in from the overlapping area between the window frame and sash?
Tighten the locking block, check whether the seal is deformed or damaged, and replace the seal if necessary.
8. How to replace broken glass?
(1) First, carefully pry open the glass press strip. When removing the press strip, use a tool—such as a putty knife—that can fit into the gap between the press strip and the frame (or sash). Start by gently tapping upward from the center of the wider side of the press strip until it completely detaches from the frame. Then, smoothly pull it out. (For wooden windows, make sure to also remove the shaped strip simultaneously.)
(2) Open the two small sides using the same method, and finally open the other large side.
(3) Take out the old glass and place the new glass in position, making sure to maintain the original placement of the glass spacers.
(4) Reorient the pressure strip and then tighten it securely. If it’s a wooden window, nail it in place first, and afterward, apply paint to fill and touch up the nail holes.
9. How to replace the sealing strip?
(1) Sealing materials come in a variety of specifications; please contact the manufacturer for detailed information.
(2) Replacement Preparation: Inspect the installation area for seals to ensure there is no damage or deformation; verify that the seal type, specifications, and cross-sectional shape meet the requirements and check for any defects or injuries. Seals should be installed in a clean, dry, and warm environment.
Before installation, the sealing strip should be loosened to eliminate any deformation caused during rolling and packaging, restoring its elasticity. To do this, simply open the package, lay the sealing strip flat, or hang it on a rack, and let it sit in an environment around 20°C for 24 hours. During winter construction, you can also treat the sealing strip by soaking it in warm water—but never heat it directly with an open flame.
Clean the window frames and sealing grooves, ensuring they remain clean and dry.
(3) Use hand tools and rolling implements to fully embed the sealing strips into the specially designed grooves on the profiled materials. When installing the sealing strips at the window corners, avoid cutting them—instead, trim the edges at a 45° angle, leaving a small connecting section to prevent cracking or gaps caused by shrinkage. Additionally, leave a 1% extra length when embedding the sealing strips between the frame and sash to account for any potential shrinkage-induced breaks.
When manually installing and sealing the strip, pay special attention to the following:
- The sealing strip must not be stretched or pulled.
- Leave a slight shrinkage allowance when cutting it.
- If there’s a cut end, avoid placing it at a corner—instead, position it along the length of the strip. Then, press the open ends tightly together and secure them firmly using an adhesive.
(4) The sealing strip for the frame should be started from the bottom-left corner, rotated clockwise, and carefully guided along the groove of the adhesive strip until it returns to its original position. Be sure to ensure it is fully seated within the groove while leaving some room for expansion and contraction.
(5) If you need to replace the seal on the fan, start from the center of the fan frame. |
