Frameless Window Leaks

I'd just take it out, clean off all the adhesives, apply butyl tape thoroughly and then a liberal amount of sealant and pop it back in the hole. Give it a day or two and then cut the tape that protrudes and seal the edges of the glass.

Yes, I think I'm going to have to remove the window. Process of elimination over many rains and trail and error of covering areas have proven it to be the window. I've caulked the perimeter o the frame. Still leaking. A friend of mine with the same rig had the same issue with a window. He stopped it by putting a bead of caulk between the opening and fixed pane as he determined it was the hinge.
That why I'm asking if anyone else has realized a leak due to the hinge of the window.
I've ruled out just about everything most simply by the fact I get no water when the window is covered with plastic during rain.
It could be that many of these windows are leaking at the hinge. Owners just don't know it if the water is not migrating to a basement area like in my case. The unfortunate thing about that is you'll never know as the water will be in the walls.

My buddy had a leak around a window no one could figure out.
He and I finally removed it and found that where the extruded aluminum frame comes around and makes a full circle, Hehr had not put sealand on it well enough and it was leaking from a tiny pin-hole at the seam.
No amount of caluking would have fixed it without removing it.

I would agree with newman. If water got past any of the window seals, it would collect at the bottom of the frame and there is a drain there. I have those frameless windows and if the frame is sealed correctly from the factory, there is almost no way for water to migrate to the basement. I would get up on the roof and see what is above where the water is showing in the basement. Might just be a vent pipe that is not sealed completely.

i seriously doubt it is the window leaking making it wet in the basemant with no other signs above it.Hence why i suggested a vent pipe etc

I'm not discounting others suggestions. However my question is specific to the possibility of the window and not speculation about water intrusion beyond the window. That's another topic. Thanks

I had a leak on one of the same windows you are describing. It was on a bedroom window where the emergency exit was on one side and a vent was on the other. For some reason the gasket or window shifted and the vertical seal was not hitting the window. I shifted it back and all is good now. It seems like water filled the inside track and was easy to detect the source of the leak. It would be easy enough to tape off the window to the trailer with some wide vinyl tape to help determine the source of the leak.

I had one window where the metal strip that holds the opening mechanism came loose from the glass. It appeared to have been mounted with double sided tape. I cleaned the surfaces with solvent and glued it back with Gorilla Glue and held it in place with spring clamps while drying. Good as new.

Just because someone else had a leak in their hinge, does not mean that yours will do the same. If I was you, I would not discount other suggestions. Water travels.

Thanks but I want to stick to the specific question.

my bet its not the window but could be a vent stack
