How would you repair this window leak

leakwindow framewindows

I recently bought my first home and a few months ago when it rained heavily I noticed water leaking inside from under the bottom window molding.

I tried to recreate what was causing the leak and it happens when water is getting onto the sill and not from the master frame connection to the brick.

How do you recommend this be fixed? I've contacted a few window companies and most say the window needs to be resealed but I'm worried the problem is with the window itself.

So if I understood correctly the water enters between the sill and the master frame. Why not seal it with silicone and this tool (don't know the word in English)?

Use plumbing silicone or other silicone used for moist environments. Place the silicone generously and detract it with the tool shown. This should seal it thoroughly.
