Removing and sealing RV cabover windows

Dear Chris,
I have removed side and rear windows that have leaked but this front window looks to be constructed different. Glass and molding around the window looks more like an auto. I removed the ring on the inside but didn’t want to force the glass. Please help. —Josie

Dear Josie,
You are right on track. You need to **carefully** pry the aluminum frame away from the wall of the coach. It likely has been sealed in place with an adhesive sealant like Sikaflex, which will be a a bit of a bear to get off, but it sure can be done. The rubber seal around the glass may be leaking as well, so be sure to check that, and have it resealed by a glass shop before reinstalling. Make sure you get as much of the old sealant off the frame as you can, and reinstall using a similar high-strength sealant. Windows on the front of a cabover like this can be problematic, which is why sealing it this way is so critical.
