I have a finished opening from hall to parlor of 41.5"' x 81". What do I need to do to prep for new doors? Can I hang new doors in the existing opening; do I need prehung doors, or may I use left and right doors only; do I need custom doors, or are there doors which come in the size needed to fill the opening?
Any suggestions will be helpful.
Thanks,

You have an odd size there..that would require about 20" doors..which I don't think you'll find.

Anyway..a little more info would help...

Do you want true french doors? Wood and glass in other words?

Whats your skill level? Do you have a tablesaw?

Is the opening finished with wood or sheetrock?

Anything CAN be done..its only wood after all, but depending on where the wall is and whether its load bearing..it could involve opening the wall and replacing framing.

 

I ran into a similar problem installing french doors at my parents house. The opening was finished with drywall but wasn't quite wide enough for 2 24" doors. So I removed the drywall to get some extra width. It still wasn't wide enough so I had to remove a strip from both sides of the doors.

This is where I ran into a problem. Most locksets are set to either 2 3/8" or 2 3/4" backsets. Once I cut the strips off the door, the smaller 2 3/8" would have put the knob into the glass panes. So I bought 4 dummy handles that just screwed into the door and placed a cabinet ball catch into the top of the doors.

Just thought I'd point out the problem I encountered.
