Non-standard door sizes (1940mm tall)

Hi there.

I am looking to replace the internal doors in my ex-council house (5 in total) but have discovered that the doors are not a standard size (In retrospect, I assume this is why the previous owners had never changed them!). The existing doors vary between 1940 and 1950mm but the standard door size is 1981mm.

All the doors I can find say they are a max of usually around 12mm. obviously this is not enough.

Can anyone advise what is best to do? I have a carpenter ready to go who seems keen to just trim away at these doors despite the guidance but I wanted to get some second opinions on whether this is a good idea or not.

Thanks in advance..

Yes, you can trim doors. But if they are hollow, a solid piece of timber needs to be put inside, to prevent the door from bowing.

The doors could be cut down however if they are eggshell hollow doors a new bit of timber the same thickness as the inside of the veneerr usually 6mm smaller than the door thickness would need to be glued into place.

Yes the doors can be trimmed but a piece of timber will need to be put back in if the existing one is removed from trimming
