Leaky Window

Well I've owned my 1993 FourWinds for one month and luckily I live in a dry climate. However, yesterday it rained buckets and I thought it would be a perfect time to check for leaks in my coach. Luckily, I only found 2. One in the right corner of the cab-over (that one I sort of expected after reading this forum) and one in the rear side window. The weird thing was that the water was seeping in between the trim ring and the window itself along the bottom. I have two questions for anyone who might have experience with this type of window. 1. Can I remove the trim ring and do further investigating without opening a whole can of worms? and 2, Do I need to just suck it up and open the can of worms anyway?

Thanks,

Lou
  • Try cleaning out the weep holes in the window - water might not be draining properly and backing into the rig.

    Given the age of the rig I would consider resealing all the windows - that requires popping the windows frames out and resealing - not very hard and here's a How to Video
  • Lou,
    I would think the proper way to repair it would be to remove the window and re-calk in behind the opening. Reinstall the window and run a bead around the outer edge. This way you know it's done properly. I've done quite a few over the years, and it's not that hard to do. Just pick a nice warm dry day and you shouldn't have any problem.

  • Thanks, Kevin and Vic.

    I checked the weep holes and blew them out with canned air. The water isn't actually coming from the window track. It seems to be coming from behind the trim ring.

    Thanks for the link. Great how-to video. Perhaps it won't be as big a can of worms as I thought! One question, though. Is he using just plain-old silicone caulk to seal the windows at the end of the video or is there a special sealant I should use?
  • I use pro flex - popular RV caulk used by many. I think silicone is a poor choice for RV's.

    Lastly - your window leak source might not be window (could be roof) - source of leaks can be tough to find in RV.
  • Go to any rv parts store and ask them for a roll of putty tape. It is cheap and common. When you take the window out and have cleaned all the surfaces, you unrill and apply a bead of the putty tape where the window seals against the side of the trailer. Push the window back into place, and while someone is holding it from themoutside, go inside and reattach the cinch ring. Carefully toghtening the screws a little at a time until things are tight. I follow this with some Dicor. They make two versions, lap sealmfor horizontal surfaces, and one for verticle surfaces. Be sure to get the right one. If you have one window leaking, guaranteed the others are not far behind. Do them all and youll be good for years to come.

    X-2,
    That's exactly what I did, and never had anymore problems.

  • Thanks for all of your tips. I finally got around to replacing the window and it was not as big a can of worms as I thought. Actually it was pretty easy. It only took me a couple of hours and it looks great. I guess the real test comes the next time it rains. I might not wait and give it the hose test, but I'll at least wait a couple of days to let everything cure.
