door jamb extensions?

Hi all,

Somewhat of a newbie home DIY'er trying to learn the process and enjoy the journey.

I was wondering if someone would be kind enough to help answer a question about a new patio door that we installed. Attached are some pictures.

My question: am I correct in believing that I need to add jamb extensions to fit and cover the exposed areas so that I can install the trim around the door?

Thank you in advance!

Well that's about all you CAN do now that it's installed. Normally you would order a door that is the right wall thickness for your wall so that you don't need to do anything unusual. Typically if you have to add a jamb extension, you do it on the OUTSIDE so that the interior jamb, hinges and threshold can all be flush with the interior wall surface.
