How to repair a leaky balcony window

Clean up the window perimeter, remove the original aging sealant, and re-seal the contact parts between the window and the wall with weather-resistant glue after drying, and fill the foaming agent if the seam exceeds 8mm.

Solution:

1. Remove along the perimeter of the window, remove the exterior wall decorative layer, insulation layer and leveling layer 2, and remove the filling sealing materials and other materials at the junction between the window and the external wall of the structure.

3. Remove the debris in the junction between the window and the structure, and use a hair dryer to blow it clean.

4. Re-fill the styrofoam into the seal, embed the sealing paste, and use the plugging treasure to seal and level the outside.

5. Brush the anti-ultraviolet waterproof coating film that can be exposed in the leakage range.

6. Finally, the water is not leaked to be qualified, and the insulation layer, anti-cracking mortar and exterior wall decoration layer of the part are finally restored.

7. Taking into account the actual situation of this project, due to the fact that the house is an old-style old house, the developer's construction quality problems need to be painted with waterproof coating film (no groove) on the adjacent upstairs.

1. Check the joints between the window and the wall, remove the original aging or damaged sealing materials, and then treat the base layer clean, smooth and straight. For the large gap between the window and the wall, fill it with styrofoam, and the inner and outer sides, the window frame and the window sash must be filled with glue and sealed.

2. For balconies with serious leakage, waterproofing should be redone, especially the waterproofing of the top surface and wall. It can reduce the impact of rainwater on the infill layer between the window and the wall. When repairing, good sealing materials should be selected, and the leakage points should be carefully sealed.

3. For the owners who are decorating, it is recommended that in order to avoid this situation, we should try to choose aluminum alloy windows with strong anti-aging ability of sealing strips, and there are no obvious gaps in the process of splicing.

1. If the material at the indirect joints of the balcony window and wall is aged or damaged, it is necessary to replace the new material and glue and seal.

2. If the balcony window leaks seriously, it is necessary to redo the waterproofing of the wall and the top surface, or add a water retaining plate above the wall.

3. If the balcony window does not have a slope and causes water leakage, a slope can be added to the outside of the window.

1. If the material at the indirect joints of the balcony window and wall is aged or damaged, it is necessary to replace the new material with a new one and seal it with glue.

2. If the balcony window is seriously leaking, you need to re-do the waterproofing of the wall and the top surface, or add a water baffle above the wall.

3. If the balcony window does not have a slope and causes water leakage, you can add a slope to the exterior of the window.

If the window is leaking, if it is within the warranty period, you should find the property to coordinate with the developer to repair it. There are only two situations of window leakage: 1. Water leakage at the contact part between the window frame and the wall, which needs to be sealed with waterproof materials from the outside of the window.

2. The window frame infiltrates into the room after water storage, which can be solved by drilling water traps outside the window frame, and the elevation of the trap hole should be lower than the indoor window sill.
