One window indicates a leak on the bottom left corner on the inside, around the trim and down the wall to the floor. There is no indication of water above the indoor sill. At installation I flashed the window properly. I installed flexible flashing around the rough opening and when the window was installed a six inch seal around the window covering the flange. The leak is minor. I inspected the sill on the outside, the weather stripping on the bottom of the window, joints in the window at each adjoining angle and as a preventative applied clear silicone.

Any observations would be greatly appreciated. I have arrived at the point to which I am considering cutting a 6″ opening from the bottom of the interior sill to the floor to see if there are any obvious flaws.

Thank you very much
