Water on the windowsill: 5 errors in the installation of windows, due to which they leak

In apartments, in the middle lane, this problem is often encountered. The point here is that during the installation of windows mistakes were made, which led to the appearance of water on the windowsill. Trouble can occur at different times of the year. And such a problem can be especially critical if the homeowners do not know about it and leave, for example, for a month.

Fixing fasteners without preliminary marking

This error is most common. Meanwhile, this is a very critical oversight. Indeed, the rigidity and reliability of the entire structure depends on how the elements will be located. This indirectly affects the occurrence of water on the windowsill, because sometimes the lack of preliminary marking or illiterate marking contribute to a breach of tightness.

Insufficient number of window block mounts

This is also a common mistake. Unfortunately, it is often performed by people who professionally install windows while working in the company. If there are not enough window fasteners, this directly affects the tightness of the structure. As a result, the risk of condensation increases, which subsequently turns into water on the windowsill.

Lack of patching after removing the old window

When the old window is removed, pieces of plaster are sometimes accidentally removed along with it. And this is critical, because there are potholes. These potholes need to be repaired. If this is not done, high-quality installation of new windows will be impossible, because there is simply nothing to be attached to the sealing material.

Proper gluing of corners with moisture-insulating tape

Such a tape helps to avoid condensation and is attached to the outer groans of the frame, ending up between the frame and the wall. However, it is important that the tape fits the corners well. To do this, you need to correctly form them in the sizing process. That is, you need not only to glue the tape around the corner, but to move part of the tape to the side so that it turns out a kind of eyelet, but this “eyelet” needs to be glued tightly and as a result the tape will fit snugly to all parts of the corner frames.

Uncoated mortar joints in masonry

If such seams are not sealed, then they, in fact, are voids into which water will fall from the street. Condensation may also be added to rainwater and snow. Over time, this will lead to the appearance of moisture on the windowsill. Such a problem begins to manifest rather quickly.

In conclusion, it is worth noting that competent installation of windows is the guarantee that no water will appear on the windowsill. Otherwise, there may be high costs for solving the problem. So do not save on the quality installation of reliable windows.
