Front window leak/no gasket??

I have a new to me Funfinder that has a window in the front. It is protected from rocks and such with a hatch door that just like the doors that provide access to my pass-throughs.

After a very heavy rain, I found water had seeped in from somewhere and gotten a small corner of the mattress wet as well as a bit of the carpet. From the location, I'm guessing that "somewhere" is the window. I opened the window and where I expected to see a rubber gasket similar to those around the pass-through doors, there is none. There is a thin 1/4 inch strip of weatherproofing foam attached to the door itself.

I'm going to spray the window down today as soon as it warms up a bit outside to see if I can force a leak (unless there is a better way). If the water is making it's way around this foam insulation, how would you recommend making a repair? Should I replace the existing foam or look for rubber gasket material? This unit sat on a dealers lot and can't help but wonder if someone removed the gasket as they did the one tail light cover and the bumper end cap.

Thanks,

Carolyn

  • During the rain storm last week I had taped up the window and the leaking stopped so I was pretty sure that is were the problem was. I had removed and cleaned the window seals and thought I might have fixed it, as I couldn't repeat the leak.

    Was washing and inspecting the roof today and the window started to leak. I took the window out and upon inspection it appears the water was only intruding into the right bottom corner of the window. There the luan was dark with moisture and the foam insulation that it was glued to was slightly damp. The luan around the rest of the window was dry with no signs of old or new leaks. I've got the window out now to allow the luan to dry before I re-install it. We are forecast for several more days of clear dry weather, thank goodness.

    Thanks for all of your responses. Spike99, Thanks for the link on how to DIY this fix. Without it, I might not have tried it.

  • Take it in to an RV service center that can perform a pressurized leak test and seal the leaks. I don't think many understand how severe leaking can be.
  • .

    If front window or side window is leaking, simply remove using cordless drill, re-seal using Butyl putty, re-install, then add clear ProflexRV (not silicone) around its outside edge. For neat edge, apply masking tape, then apply the ProflexRV, level off with wet finger, then remove the tape. If window has foam strip on its inside lip, simply remove. If wondering, Butyl putty replaces this foam strip.

    If wondering, I re-sealed 11 of the windows within my 2006 Jayco. To my surprise, 3 of it windows were leaking (1 leaking really bad). And, I didn't even know it. Glad I did this DIY maintenance items to my 2006 Jayco (when it was 4 years old).
  • If all else fails, you might want to pressure test the trailer and track down leaks with soap bubbles. Beware, this is not for the faint of heart, you will find the leak you are looking for and probably some others, but it works.

  • I think you are taking the same approach I would. Good luck.
  • I've not been able to make the front window leak. This afternoon's rainstorm revealed why... it's not "that" window. It appears the leak was coming from the side window and gravity was pulling the water across the carpet to the corner.

    This window has a missing/broken screw and I think the water was coming in/ around the rubber seal that holds the window in on the outside. It looks like, if that happens, it is supposed to drain back out a groove that is notched into the bottom of the window. I think the water may have been draining out through the screw hole into the trailer instead. I've caulked the hole, temporarily and cleaned inside of the seal, removing quite a bit of dirt. I've not been able to repeat the leak so ... fingers crossed. We're expecting plenty of rain to test my fix.

    FAIL! Rain has really picked up and water is dripping into the trailer from the bottom of the window, between the window and the wall. Going to try to tape up the window entirely from the outside to see if the leak stops. If it doesn't, It may indicate the leak is higher up and just finding an exit there.

  • I would go ahead and remove the window, check for damage, reseal and replace the window if you know that is the area it is coming from. The leak may just now be presenting itself but may have been leaking a while

    Carolyn,
    If you could provide a few pictures it might be helpful for us to see exactly what you have there. On my funfinder, the "rock guard" over the front window is actually quite different than the doors on the pass thru compartments. So perhaps the previous owner of your trailer has changed something on that trailer.
    On mine, the window assembly itself is sealed with typical butyl rubber tape between the window frame and the outer skin of the trailer itself. As Wayne said, the rock gaurd itself is not sealed for weather, since it on the ouside of the glass it does need to be. It's function is simply to help protect the glass from breakage.
  • If the hatch itself has no gasket then I would think that the window would be a sealed pane of glass. That is how it is on mine - I have a hinged window cover which has no gasket but the window is a proper sealed unit. I expect no leaks (have not been in rain yet). The leak could be coming from the window proper, and the hatch is immaterial to this issue.

    Pictures would help.
