In between the two large windows on the passenger side, just in front of the dining table, below the wall mounted light, is a swelling of the interior finishing material. Also, the new laminate flooring below that location is swelling along the wall and extending into the room up to 8 inches.
From the outside, there doesn't seem to be any swelling of the fibreglass of the wall, nor is there any break in the fastening of the gutter. The location is about half way along the Girard awning, but again there doesn't seem to be anywhere that the flange attachment is separating from the outside wall.
The only rain we have had was a three day heavy rainfall just before we left home in late October. At that time I had a serious leak from the gutter above the driver's side window. There the gutter was separating from the side wall by about 1/8" over a 12" length, right where the front cap and the side wall met, and the water was entering the wall and coming down the inside of the window. At that time I checked for other leaks, but there was then no swelling of any interior finishes at that time. I suspect things had to stay wet for quite a while to get the swelling. That location is behind the easy chair, so rarely exposed to scrutiny.
Has anyone had similar leaking, and if so, how have you located the source of the water?
Is the Girard assembly not water tight? Do I need to caulk the gap between the flange and the upper part of the housing?
