There are many reasons you might want to replace an internal door frame. It could be that the existing door frame is rotten or damaged, or you might wish to change the direction that a door opens, and therefore want to alter the jambs.
The good news is that replacing an internal door frame does not require much specialist equipment, and is a fairly simple job for someone who is confident in DIY.

A door frame, or door lining, is made up of two jambs (one on each side) and a head (at the top). To remove the frame:

Once you have an exposed rough opening, it is quite easy to replace the door frame. When you buy a door lining kit, it will come in a few pieces, which will need assembling before you can insert them into the opening.
A standard sized door frame kit should come with a head which has some recessions, or ‘rebates’, which are spaced to suit common door sizes. One side will have rebates that will fit a 30” wide door, while the other side of the head will have rebates spaced to suit 27” wide doors. If your door is not one of those standard sizes, then you will need to cut new rebates yourself.
With luck, you will have been able to remove and replace the architrave without damaging it or the surrounding wall. You may need to do a small amount of repainting though, to achieve a finished look.
Once you have replaced the frame, you will need to re-hang the door, and put a striker plate in the jamb at the correct height. You can look at our other guides to see how to hang a new door, including how to fit hinges, locks and striker plates.
Fitting an internal door frame does require that you have some knowledge and DIY experience. If you are not confident in your DIY skills, then you should seriously consider hiring a contractor to do the job for you. Fixing mistakes may take a lot of time, as well as money to employ a contractor to undo any damage caused by the failed replacement. Doing things right first time will make life much easier for you!
