fitting 35mm thickness doors into 40mm depth frames

Hello Hello

first post here - hopefully the last ;)

anyway - we've just moved into a bungalow built in 1961 and we've replacing the godawful internal doors with 6 panel Regency doors.

The ones [b]she[/b] bought are 35mm thick and the old doors are 40mm thick.

So - what's the crack? She has fitted one as normal with the hinges on the edge of the internal recess as you would normally do, but this means that there is a recess on the hallway side where the door doesn't fit flush into the frame as it doesn't reach it.

The options I think we have are:-

1. site the hinges further into the recess by the appropriate amount and chisel a small recess for the hinge part of the hinge :roll: (the round but) so that the door can't be over-pulled into a gap from the hallway side.

2. buy thin pieces of wood of appropriate length/thickness - secure in place with No more Nails or similar and then sand flush with door frames - which will be repainted at a later date


So, whaddya think or have we made a terrible, terrible error here?

hiya,option 2 is the normal way to go but first check if you have a removeable slamming strip,if so take it off and refit it closer to the door,

let us know how you get on.

fit the door flush to the frame on the 'opening' side. remove the door stops on the 'closing' side and refit to suit. easiest and quickest (and neatest) option.

not all frames have a removable stop,if the frame in question does not then chris your easiest and quickest (and neatest) option is not an option at all.

yes this is true - i worked on the assumption it was the type of set up that had removable stops which is the more common.

Hi I know it's very late after original post, but just wanted to say if the old doors were 40mm then these doors will have been metric doors and the 35mm doors you then bought to replace were imperial so I guess the height and width would also of required re-sizing and a lot of additional work. Measure once springs to mind!
