Window water leak

[ewacowboy]

Woke this morning to find water rolling down the garage wall below the non-opening window next to the door Not knowing anything about these frameless windows, where is the first place to look for sealing? I've never had a leak in the rain or while washing the coach. This Texas rain was pretty heavy....could that be the problem? Where should a guy start troubleshooting

I had a similar problem... turned out that near one of the corners of the window there was a small gap in the caulking. Easy fix.

First thing is to verify that it is the window and not coming from some other spot. Water has this funny habit of running downhill. It could be something higher up and the window is the path of least resistance. I had one of those in our old Airstream, drove me nuts trying to find it.

This is where a moisture meter comes in handy.

If it is the window, it should be removed, cleaned of all the old caulking material, apply new butyl rubber tape and reinstall.

X2 for cleaning and resealing.

It's the window...had the same thing happen with the same window.

Unscrew/remove the frame inside.

While standing inside, you can remove the window and bring in through the hole.

I found 1/4 inch wide foam around my window and the hole cut slightly too big. I used 1 inch or 3/4 inch foam to go around the window, installed centered in the hole, while wife was holding it, I filled the gap all the way around with expanding foam (water proof type), then reinstalled the frame. No problems since.

I did a thread on here, let me find it.

Be careful and/or use the low expanding foam.

I make the mistake of using the super duper. 900% expanding foam around a patio door window. Wow, I made a mess! Wife was not amused, oh well her problem, she don't have a sense of humor.

Don't be lazy... like me, and try to use residential weatherstripping.

I replaced a broken frame-less window recently and the weatherstripping I bought off the shelf at the hardware store was too thick to get the frame screwed together. A trip to the RV supply store for the butyl tape mention above and it sealed better than the foam type OEM tape.

This butyl tape will squish out the edges as you set the window so you know that you have a good seal, then I just trimmed off the excess with a plastic putty knife.

Hmm, I didn't think of the butyl tape, I just put back what was there, only wider. I will keep this in mind for when the next window leaks...
