Help I’ve Got A Leak...

[Alumiduty]

My rig is a 2007 25ft FB Safari. I have recently gone over the entire roof with Henry TropiCool white sealant and done a great job. My wife and I are still chasing a leak in the front bedroom under the left side window. Does anyone have any idea where this could be coming from. Ive resealed the window with Vulcamm 116. That didn’t do it. Starting to feel like this may not get fixed.....Any help would be great. Thank you all fellow streamers......

Welcome to the forums.
Check around the clearance light, wing window, rock guard mounts, segment seams, and rivets.

Sealing the front curved windows can be a tricky affair. I had to do mine 3 times before learning how to make it last (for a few years). Eventfully they will have to be completely removed for a "permanent" fix. You don't say where water is showing up. It does travel in seemingly mysterious ways. The center window seal design (cut corners) is a poor sealing method. The leaks from them will show in the center window sill trough, but can run to the corners after draining from that sill. The track holding the center window rock guard has a stringer behind the outer skin which will channel the water to the sides. Once water gets down to the bottom C-channel, it can travel quite a distance before showing on the floor.

Here’s a blog post that might help.

I tried that first, but could never get the Tolley's to dry and cure. My windows were holding water under in those cavities shown filled with the Tolleys in your pics. Unfortunately, I have outdoor storage and it would never dry before the next rain. Also, my leak was severe enough that the Tolleys just ran through.

Might work for OP, but every leak is unique.

Thanks. The leak is below the left side window on the floor. Water seems to soak in from the floor up.

Ummm, didn't the 2007's have a problem with no sealant under the bumper wrap at the bottom of the shell. I seem to recall lots of people having water infiltration problems on 2007's due to this.

Could be nothing to do with the windows; just saying.

Where specifically? The reason I am pinning you down is because, as I stated above, water will travel in the floor c-channel. There is a joint where the flat front panel meets the curved corner panel and another where the curved corner panel meets the flat side panel. The exact spot of water on the floor will help localize "quadrants" of diagnosis.

If it is in fact the curved corner window, you should feel moisture along the bottom of the window glass where the sealer and window bottom meet.

OP says front left corner, not rear. But you are correct. Not as bad on my Classic, due to bumper design, but I have a persistent leak in the LR corner, right by the trunk access bottom left corner. I'll find one, fix it, only to return a few months later.

When chasing leaks, I often "seal" the suspected area with blue masking tape and/or painters masking film with the blue tape already on the edge. Then, I see what happens the next rain. I found this can prevent a lot of necessary resealing and help pinpoint the leak.

I had a leak at my under my front windows that drove me nuts. One rain it would be on one side, the next maybe the other or both. At first, I thought windows, next battery boxes, next trim. In the end, it was from the front roof vent cover. It had a hole about the size of a dime. Water was running down inner skin. The trailer was always level. Had I raised the nose, the water would have probably showed up in back corners and I would probably still be looking for the leak.

Yes, and you can water test, starting at the bottom of the suspect area and working your way up. Localize this methodology horizontally, quadrant by quadrant. Dry wet area inside first. Be patient. Soak a small area....wait for time for water run inside walls before moving on to higher/new areas, or you will chase your tail.

Check the bathroom vent seals. These should be replace about once every 5 yrs. Airstream has a kit for replacing these . You might have two, depends on your model good luck.

Most RV window frames have weep holes along the bottom. They get filled up with dirt and debris often. They must be kept clear. If not, that can cause a leak.

I have a 2007 Safari 27. Check the seal around the perimeter of the fantastic fan flange at roof, and also the seal where the lid closes. If it is dry or cracked, wind can blow rain in there. Also check the top edge of the belly band. The leak can travel quite a way from the source.
Don't give up. Good luck!

Take it to a dealer and have them pressure test the trailer. Best way to find leaks for certain. Ask me how I know.

Ive done a lot of leak searching in houses/cars and trailers over the years and slowly testing from the bottom up is the best way to try and locate the area ...... definitely check the rivets !!

Airstream windows have no drains...

Can someone direct me to the correct URL for the bath exhaust seals please. I found a roll of seal, but I doubt that is what I need

Thanks

[Wayne&Sam]

On my 2007 20' I had a persistent leak in that area. The culprit was the seal on the hinge of the center window solar guard. An easy fix, but it required regular re sealing.

Once water gets in it can travel and show up far from the source.

The marker light seals are substandard on older airstreams and can cause leaks. I think 2012 back can have bad marker light seals. Airstream sells heavy duty replacement seals.
