Leak from window

[Redsand]

We had some rain the past few days and I went out to check on our new to us Chateau and as I reached for a tissue the box sitting under the kitchen counter window was totally soaked. Stroke of luck it was there and wicked all the water.
So it seems there's a leak from the window. It's coming from inside the slide grooves and I'm concerned this has been going on for some time. I was able to seal the counter top edges but I felt some uneveness which indicated it's not a new leak. Anyone have any thoughts on a window fix? I'm not familiar with this type sliding window so any suggestions?

Thanks RS

It should have weep holes/slots in lower outer edge. These are supposed to allow the slide to drain water outside. These can get clogged up. Might be as simple as cleaning them out.

I second the cleaning of the weep holes at the bottom. I suspect this is primarily an issue with sliders and not so much with awning/jalousie windows. We have the weep holes on our driver and passenger Class A windows clog at least once a year, which causes it to fill up the tracks and drip into the coach. Our driver/passenger windows really aren’t that much different than any other window in the coach except the rest are the awning style. I just use some compressed air from one of those computer dusters to blow the pollen/dust out weep holes and pour some water into the track to ensure all four of them, in our case, drip normally. It’s now part of my normal spring maintenance and just keep an eye on it the rest of the year.

You may want to climb up a ladder and check out the top of your windows. They should be installed with a foam seal between the outer frame of the window and the wall of the coach, and some caulk across the top and down the sides a couple of inches. In my case I found two windows where the caulk was so anemic that it wasn’t doing any good and the foam seal was misapplied, so it wasn’t doing anything in one small section across the top. I could gently probe it with something thin and metal, it would slide in a ways and could feel it touch the window frame. I caulked between the frame and wall with some GeoCel clear ProFlex and it’s been dry ever since. Ideally I should pull the window and redo the foam seal as well, but didn’t have any helpers at the time.

Frameless windows are just like framed windows, just the window glass is adhered to the outside and slightly larger than the frame which covers/obscures it on the outside. Installation, seals and everything else is virtually identical between them.

I also found that the window openings were cut poorly on ours so the bottom corners on one side of virtually each window wasn’t sealed with the foam seal. I think there might have been an aspect of poor seal installation contributing here as well. Same solution as above.

If you have a fresh water fill in that area, caulk around the neck of the fill tube. I found that frequently the inside of mine would fill with water faster than it would drip out the bottom (could actually see a water line in there because of dust) and get into the coach through the neck since it’s designed poorly and doesn’t make a good seal.

I also found plenty of similar issues on a Jayco TT we had prior to our current unit, so I think it’s a general industry failing instead of just a Thor thing

Thank you both for the tips. Yes the track was filling with water and spilling onto the countertop. I'll clean the weep holes (slots) as well and that's the probable culprit. Another maintenance item to add to the ever growing list of new things I need to watch.

Merry Christmas
