you sure the leak is from the window?

one project i worked on before the leak is at the window. but in the end actually the leak is like a meter above the window. the contractors drill tons of holes into the wall surrounding the leak and shoot some sorta foam type sealant thing that is supposed to squeeze through all those gaps and stuff. in the end all kaotim, no more leak. but it took a long time and lots of lobang.

ahhh yes. this thing. was damn messy. a lot of clean up work and scraping off excess. but in the end settle.
