Patio door replacement (Sliding)

Hello
I am replacing a patio door on my second level and have a few question with respect to the vinyl siding after the install.
The existing door has a build in "J" channel that allows the siding to tuck in very neatly. The new door has more of a "flange" that would be used to screw the door into place once installed.

I have included some pics of the old door and some drawings of the flange looking from he top down. The contractor want to remove the flange on the new door..then install J channel to accommodate the siding. In my mind, I want the flange to remain as it provides an excellent water barrier in driving rain.

So basically I am looking for options...can you just reinstall the siding without J channel? or possibly would it be better to install a moulding around the door, (3/4 inch vinyl) then install J channel outside of this and then cut the siding back to cater for the extra 3/4 inch trim?

Any and all comments are welcome

Jim

You would leave the flange and install j channel. Just take the siding down first.

@XSleeper, so basically just to clairfy....what you are saying is install the door as per...flange and all, then place the J channel on top of the flange and re-install the siding (?)

Assuming the door is the right size, yes.

By removing the existing J channel and siding around the door you are able to install the new door with the exterior flange just like new construction. Also make sure they tape the perimeter using the proper tape for water and draft protection. Then the old J channel and siding can be reinstalled in their original position.

@PilotDane, as per my post, the old door has an already manufactured channel around it...(see the second last drawing), therefore there is no existing J channel to retrieve and reuse.

As per XSleeper's comments, I believe his option is the best...just install (store bought) J channel around the flange after the new door install...the only issue would be the extra "width" at the flange level may interfere with the siding a bit, but we would only be talking less than 4 mm (?) at the most.
