TT Window Maintenance

I am a total newb when it comes to Travel Trailers, just purchasing my first. It's a 2004 Keystone Cougar 29RLS and my head is spinning regarding the window maintenance!!

I've been told that there has never been any issues with the windows leaking and I can see around the edges of the windows on the outside I can still see where the excess window sealant is around the corners. Although it is cracked every few inches around it.

Since the TT is going on 10 years old, is there any recommended maintenance for the windows to at least scrape out the cracked stuff and reseal with the ProForm type of sealant??
I've been sealing a lot of people posting that the windows need to be removed and resealed completely but I am wondering if I should just take the approach of "if it's not broke, don't fix it"???

  • Thanks so much for everyone's response!! It helped a lot ease my worries.

    I'm planning on giving the trailer a good wash this weekend to get all of the dirt/black streaks off, touch-up the verticals with the Dicor Non-Sag Lap Sealant and touch up any roof spots with the Dicor Self-Leveling.....
  • I wouldn't pull out a windows unless there was clear evidence of a leak. Just trim off the excess and reseal with good quality caulking. Inspection of seals and resealing/caulking is part of regular maintenance. Inspect every seal no less than twice a year.
  • I would suggest you plan on a day for getting all over your rig and sealing everything. The roof through-holes for vents, AC's, etc. is one area. Around any siding and trim is also important. If the windows aren't leaking, as long as you have caulk gun in hand, go around the perimeter of the window after you have carved out the squeezed butyl tape. There is no sense to seal failing material, IMO, and any cracked or loose sealants should be removed first.

    I use a lot of different caulks and sealants in my occupation and found that the Geocel products like Proflex RV is an excellent sealant for my trailer. I am currently using Geocel Tripolymer 2300. It has a slightly better elongation rating than Proflex but not much. Geocel is now making another sealant that is for the trailer and mobile industry, 2300 MHRV, which has an even higher elongation rating. I may try that next.
  • Until you see a window leak,do not loose any sleep over it.I had one leak with present rig, and I cured it with clear nail polish 3 yrs ago and its still holding on.
  • My windows didn't begin leaking until the RV was 15 years old. You can scrape out the sealant to create a channel and add new sealant. You need to use sealant designed for RVs.

    The best method is to remove the windows and reseal properly.
