I bought a property in August 2018. A month ago, so far twice during heavy rain and wind, the water started to leak above the kitchen window. There is a small gap between the window and the wall and water is coming through there. I marked this with yellow on the pictures 05 and 06. At first, I thought that I needed to replace the windows and fill the small gaps with a sealant so I called a designer to give me a quote. After he inspected the kitchen and the window from inside and outside he told me that there is nothing wrong with the window itself, but that water is coming from the outside wall somewhere from above. The roof is inspected and there are no leaks in the property above mine. As can be seen on the kitchen ceiling, there is no damp or leak. There were also no damps or leaks previously in the kitchen (see pictures 01 and 02 from 2015 and 04 from 2018). The previous owner has done some work on the outside above the kitchen window (see picture 03 from 2015). I am wondering whatever has been done back then could be botched work and what could be an issue? Lintel, cavity tray? I have no idea how to approach a problem. Should I call a local bricklayer or construction company? What they should repair? Lintel, cavity tray, or should they re-roughcast externally to weatherproof the exterior walls? Overall, the apartment is in very good condition, with no leaks on other windows and no sign of damp. In the beginning, I foolishly believed that I can fix the issue on my own with a little bit of sealant, but I will need an expert. Any help is more than welcome.
IMPORTANT EDIT TO THE POST
I have noticed that the window is not properly sealed from the outside. I was wondering could this be the initial problem? Is it a good idea to seal it with Geocel TheWorks which is an all-purpose sealer and adhesive and afterward paint the outside window walls with water-repellant paint? If this fails, should I check for the faults in the cavity tray?

Stucco absorbs water and it should run down behind the stucco and drain out at the ground .It looks like the header over the window has been repaired once already, likely

a water leak problem that was not solved then.

You could have a leak at the window upstairs also,

The lower windows need a flashing to let the water out above the window.
In the video you can see how hard he works to get the paper right and his window has a track for the water to go down and out.

I had a person inspecting the property. He suggested that the probable cause for the leak is in the joint in the old and new render. Hopefully, the plasterer will re-render. I should probably wait till spring as the rest of January and February will be rainy.

More often than not the problem is the window upstairs, what happens is any water that gets in around that window can get behind the tar paper and the it comes down and runs into you window and it has no way to get out.


This has been an ongoing problem since they invented windows.
Codes were changed in 2006 to solve this problem.

Now we except that all windows leak sooner or later and we install them in a way that will give the water a way out.

Any window that will get rained on needs a flashing above so you window is missing that, and we can see by the age of the building that the window installation is likely part of the problem.

This is what we do now to solve this problem
