We would like to replace all internal doors in our house that was built in the 50's. The only issue is that nothing in this house is of a standard size! The door frame height seems to be ranging from 2020 - 2030 and I was wondering if it is even possible to trim hollow core doors at all? Or do we have to go for custom sized doors which are a lot more expensive?
Monamona Once had to do this although it was to make an even shorter door. I just cut it to length at the bottom took the horizontal piece of wood from the offcut clamped and glued it back in with a couple of brads each side and aquadhere. Make sure to seal it (paint the bottom of the door) so moisture doesnt get in and cause sweling later.
Hey @monamona yes you can but it does depend on how much you need to cut off I generally just use an electric plain to customise a standard door to fit where I need it to go
You'll most likely be using doors which are 2040mm high. If you need to take off more than 10mm I'd recommend splitting the difference between the top and bottom. There are strips of timber around the perimeter of the door and cardboard in the interior. When splitting the difference it ensures the structural stability of the door is maintained and that you don't go completely through the strip of solid timber. As @JDE mentioned if you need to take off more than the thickness of the strip of timber you can simply cut and reposition it.
