Scamp front window leak -

[John Carter]

So I have water leaking in the bottom of the front window, top of cushion is soaked. What's your best guess? The gap in the window gasket? What should I caulk it with?

Thanks,

John

First, did you clean the weep holes? The little slots at the bottom outside of the window. Some folks use trimmer line. I use insulated wire. If they are good, then have a helper spay the window with a hose while you are inside looking. If you have to pull the window butyl tape is the stuff to use. Any RV dealer will have it. Use the search feature to see lots of threads on the subject. Raz

Year of trailer and/or picture would help. Different years different windows.

If your window has weep holes on the bottom of the window on the outside, you might want to make sure they did not get clogged. If your window "suddenly" started leaking at the bottom, could be overflow from track if your weep holes became clogged.


Don't forget water flows down, sometimes through hidden areas like behind frame or wall covering, where you see water may not be where it got in.

You might try using a watering can or plastic cup and bucket to figure out where it's leaking. Do a binary search, slowly water bottom left half, then bottom right half, then repeat on top left/right until the leak is found. Should be able to track down which "half" is leaking, then zero in on source by splitting that area in half and watering one half at a time.

No point in caulking or seal replacement unless you know that what you are caulking or sealing is where it leaks.

Trailer is 2001 Scamp 16ft, no weep holes in front window, just rubber gasket. I bought the trailer used, maybe gasket is not original, I don't know. I'm familar with butyl tape, not sure where it would go if I pulled the window (last resort).

Man after my own heart, John. Could be the whole shebang has to be pulled, cleaned up, and rebedded on butyl tape. BUT. . . that gasket is there for a reason and I like your thinking about the gap because it was my thought a few months back that simply plugging it might prevent water from sheening down and getting in thru the gaps at the lower mitres. Tear off a piece of that butyl tape, press it in the gap AFTER cleaning with compressor blow gun, toothbrush and Windex or what's at hand. If your window frames are black anodized or just black, match the grey butyl to the frame with a black MagicMarker. Quick, cheap, what can it hurt? If the leak doesn't stop, the hose and inside observor scenario will still be an option. I'd sooner do this little fix on spec than pull a window and rebed (on spec).

This is very similar to the front window in my Scamp, in fact Kevin uses a Scamp gasket in this video

. I can't see any application of butyl tape in an install such as this. The gasket around my window has a significant gap between where it starts and ends, maybe 1/8 inch, I'll plug this with the butyl tape and do the water test.

Why can't somebody just make a complete trailer out of butyl tape? - it would never leak.

The frame is the item which is bedded on butyl tape, John.

It never had weep holes on the front window- the gasket is probable original.
