My doors and windows leak air and rain. Do I have the right to have my house repaired?

1, do a test on windy days, find out where the air leaks and see what the reason is. Seals-rubber strips are aged, cracked and worn. Replace the seal rubber strip. If the warranty period has not passed, find a manufacturer to replace it. After the warranty period, you can replace it yourself, or you can ask the manufacturer or the head office to pay for it. This little problem is easy to deal with.

2, the installation is not in place, the installation process is not correct, the window must be horizontal and vertical, which is the basic element of no air leakage, otherwise the window will be deformed after a long time, and air leakage will inevitably occur after deformation. At this time, the air leakage problem is not easy to repair. After the warranty period, you have to find a manufacturer and spend your own money.

3. Is the process of styrofoam correct during installation? The correct process is: first, fill the gap between the window frame and the wall, and spray water evenly on the wall with styrofoam before filling the gap to keep the wall dry and not wet, which is the premise to ensure that it will not crack after gluing.

4, fill evenly, don't leave gaps, if there are gaps, be sure to fill them. After curing, it should be cut neatly with a blade and evenly coated with sealant inside and outside. After this work is done, it is not easy to leak rain. Knowing this process, you will know what to do if there is air leakage.

5. Another reason for the deformation of the window frame and sash is that the angular strength between the horizontal frame and the vertical frame is not well grasped in the production process, and the required angle is not reached, such as a 90-degree right angle, that is, 88-89 degrees, which is caused by uneven stress between them. In the same way, find a solution from the cause.
