Leaky@ss windows

I swear Iím spent a crazy amount of time unsuccessfully trying to stop window leaks... I have a 2002 Amtran RE, the water keeps appearing in the corners so of the windows. Iíve probably invested $50 worth of caulk trying to seal them up. I think a may have to caulk the insides of the bottom part of the windows, but that seems strange considering all the moisture is coming from outside... Anybody have similar problems and or advice to stop the leaks?

Did you pull the window units out to recaulk?

I did a couple, but mostly scrapped and recaulked from the outside.

I'd say that in order to effect a successful long-term repair you would need to pull the window assemblies, clean and recaulk, then reinstall.

I can guarantee, providing the window assemblies themselves don't leak, that if you used 3m 5200 for a caulk they would not leak.
On the downside, you couldn't ever get those suckers out -- at least in one piece.

Good plan.. I may take this approach. Itís jus really puzzling because I can SEE all the joints on the exterior and the look good...

Though I wouldn't the 3m 5200 as a caulk for the windows. Use something you can cut out. They used a butyl caulk on my '84.

We had persistent leaky windows on our Amtran too. Amtran is apparently known for leaking windows. We pulled all of our windows, cleaned the metal window assembly with acetone and a wire brush (using a drill attachment) so they were spick and span clean. Those suckers looked brand new! Then we cleaned the mating surfaces on the bus itself, down to fresh paint (removed any traces of butyl tape). Then we use 3M Dynatron 550 on all mating surfaces and put them back together. This was a solid 2 days worth of work. It wasn't all that bad, truthfully. Put on some good tunes and have a partner to help ya. Having said all this.....the windows STILL leaked. Especially in the corners.


It turned out that the water was coming in at the bottom of the glass, where the rubber gasket is supposed to seal the glass-metal union. The rubber was a bit dry rotted and it let water into the metal window frame, where it travels down to the corner and to the inside of the bus. Our temporary solution was to put a strip of clear weathersealing tape at the bottom of the glass, covering that gasket. It works like a charm. Our plan is to just caulk over that gasket, but we've got many other projects ahead of that.


Bottom line? Try sealing the rubber gasket before you pull any windows....that just may be the ticket and save you lots of frustration.

Perfect! Thank you so much! I replaced one of the windows so I had the frame out and examined it and the corner where the water pools is higher than the part of the frame where water would go if itís entering behind the actual frame so itís gotta be the glass seal..

Only pulling and resealing stopped my leaks

It was definitely underneath the glass seal. I cut the window sealant with a razor, peeled it out, and tapped it down into the seal to create a space for the new caulk to seal up things. When I tapped the old gasket down into the window water was splash out in my face.

Iím confident I found the source.. Iíll know soon enough
