Hi all,All my apartment windows are leaking from the bottom corners right above the windowsill. I tried to repair the first one but as soon as it rained it got wet again. I used silicon to caulk around the edges and repainted the wall. Second one is in worse shape. I spent hours googling the problem, caulked different places as suggested by different forums... but water is still seeping through.I poured a whole 1 liter bottle of water into the window's drain but no leaks there. So I don't think that the problem is the aluminum frame as such.Any help is greatly appreciated.Please find photos in links below:http://ift.tt/2wPTFia http://ift.tt/2wfMYm1! via /r/DIY http://ift.tt/2wPK8rw
