You'll need 2 people at least to get the window out. Start by removing the valence…there are screws both at the top and the sides…at least on our 2012 Majestic there are. Once that's done there are some screws on the inside that hold the inside half of the mounting in place. Carefully remove these while somebody holds the window from the outside to keep it from falling out. Once the screws are out take the inside piece off and then it just slides out of the hole from the outside.

There's some foam sealing tape that NH uses to seal them…you'll have to replace that but I recommend using butyl tape instead of the foam stuff that NH installs. Clean the edges and put the butyl tape on and then reverse the removal process to reinstall.

Once the window is installed take an Xacto knife and remove the excess butyl tape from where it squeezes out. You'll have to repeat this step and (maybe) tighten the screws holding the inside piece of the mounting a few months later…and maybe a few months after that…as the butyl tape is basically rubber like and sort of oozes out. I used gray butyl tape because it was what I had…if I were to do it again I would look for black to make it less obvious.

The window will stick out a little farther from the fiberglass with the butyl tape…that's normal.

Removal and installation is actually reasonably easy as long as you have enough hands.

Our windows are the older ones they used…Heil or something like that is the name…I imagine that all frameless windows are pretty similar in construction.

You could get an RV repair guy to come do it…but it cost you 2 or 3 hours of labor so probably $300 or so. Having done it once with our repair guy down here when one of ours leaked…I would do it myself next time.
