How to reseal windows and seams on ext?

[maxwell18]

Just had my motorhome roof and all windows and all seams on the ext of my motorhome resealed. This was done by a professional RV tech. The finished product was the windows were sealed across the top and down the sides, but not the bottom of the windows. Said will allow for drainage of water if it get's in the windows. Does that sound correct?

Yes

Well, yes....and...no...
To do the job right, the widows should be removed, and, the butyl replaced. The windows are "squeezed" on the walls, trim ring on the inside is drawn tight, squeezing the butyl that is on the inside edge of the outside part of the window.
To seal with silicone only on the outside may, or, may not get the job done.
To be sure, it is a two person job to do it right, but, doing what you had done, is way better than nothing, and, yes, it is ok to not seal the bottom...hope it all works out...

Agree with free-to-roam. I pulled the windows out of our TT years ago and cleaned the area and put butyl tape and replaced window. I then put a bead of RV caulking around the window to keep moisture out. Each window has a weep hole to allow water to drain out of it.
