Window leaks....????

[dchafer]

I am in British Columbia on Washington border. We have a new (sep3/05) 3400RL. Sitting in the lazyboy we noticed the bottom small window sill of the picture window was soaking wet.. wall is not wet, cold and damp but not wet, we have purchased a de-humidifier which is priceless here.
I phoned our dealer and they say this is normal and its just the way the window is designed. I am worried that the frame was not properly caulked before installation. Has anyone else experienced this problem?
I will keep my eyes on this one. thanks, Diane.

Not in our Montana, but our previous TT developed a leak at a window and all that moisture actually allowed some little toadstool looking fungi to grow in the carpet!! I'd say it needs to be looked at by your dealer to make sure and then if your not satisfied with his answer elevate it to the Montana folks at Keystone.

With most railers And 5th wheels condensation is a problem the one thing we do when camping in cold weather is to leave a roof vent cracked a very small amount and this has seemed to help but not eliminate the problem. Give it a try. Roman

Dechafer, Your problem could be condensation, but check and make sure that the glass is sealed in the frame. I have had problems with windows in 2 units. The problem is the windows that do not open. They are sealed with polyurethane caulking, some spots are not sealing and water, generally rain, weeps in around the glass. Hope you get it cured.

I don't believe it's normal. Our rig had the same problem and I thought it was condensation. However, it only occurred when it rained. So, I used some clear sealant and calked all around the outside of the grommet that goes around the big window. Then I calked around the inside of the grommet (where the window fits into the grommet). When I finished, using a wet finger I smoothed the caulk on both sides of the grommet. Voila! We've not experienced any water collection at the bottom of the window sill in over a year -- and we've been in some real downpours.

You also should go on the outside of the rig and insert a small flexible piece of wire in the drain holes on all the windows to make sure they aren't plugged. From traveling all over, debris can collect in the holes and the humidity can't drain properly. The windows are designed to drain, not collect water.

Hope this helps a little.

My 06 2955RL has this same problem and I know what causes it in my windows. The bottom sliding windows have to move against a seal to open. That is how sliders work. A slider is never as tight as a tilt out window that cranks down and squeezes the seal and does keep out 100% of the moisture.

Now all the above posters are correct and there are windows that leak in different ways.
I decided I will never open those little sliders on my big picture window so I was careful and did a neat job of applying a silicone sealant on the seals that rub against these little sliders and now my window track is dry. These windows will not slide now unless I remove the silicone.

I do believe a sliding window should keep water out better than the windows on my Montana do.
When we get a lot of rain and wind I will get a moist track on the other windows as well but they do dry up when the wind stops. The picture window was the worst and now it is ok.

Good luck getting your problem solved but with a de-humidifier, your rear wall should not feel damp. My rear wall below the picture window is always dry so there is a chance your windows are leaking in other places as well. Take care, Don.
