Exterior Casings With Integrated J Channel?

Can exterior casings be put around a window that has an integrated j channel?

Yes make sure you have 6" or better window tape around the flanges, and I usually set the new casings into a heavy bead of caulk. sometimes I will even bend some U channel on the break to fit into the J pocket to A) prevent water from getting in there, and B) to give some surface area to put caulking on and set the new trim against.

Hi Patrick, Can you send me some pics that show what it looks like?

Patrick

I do not have any pictures at my immediate disposal. It looks alright as long as the casing that is currently on the vinyl window is not a brickmould profile because then it will look kinda stupid and stand out as having double trim. What kind of siding are you using? Most window companies have an L fin adapter that covers the J pocket so you can use regular siding.

Whenever possible I try not to use caulk. Sometimes you have no choice but caulk eventually breaks down.

I was going to link you to some pictures but it says I need 15 post's before I can post URLs.
