I got water penetrating under the window of a first floor. I feel that they might some space under the window or maybe some very small cracks on the rendering allowing for the water to get through.
How can this issue be fixed please? does the surface under the window need a full repaint after the fix here? as I'm concerned the whole front house, if not house, would need to be repainted after that else it will visible some work had been undertaken just under the window.
The windown width around is 1 metre.
Thank you
