Remove a Crittall French Window without damaging

Postby benawhile » Tue Aug 04, 2020 7:14 pm

Good evening

We have a pair of galvanised steel, presumed to be Crittall, french doors which need to be removed without damage, to be re-fixed internally in an existing internal archway which may need resizing and is in a solid internal brick wall.

We won’t be keeping the present glass but will replace with some kind of safety glass up to modern standards

Any general advice welcome, but in particular how do we separate the hinges from the door frame without too much damage? In the photo there is a gap between the pin assembly and the part of the hinge that is welded to the frame, where we might be able to prise the pin apart.
Is this a riveted assembly? The hole in the bottom doesn't seem to fit an allen key.

One of the photos shows that there are some large screws that hold the frame in place, would anyone be prepared to postulate that they are the only means of securing the frame, or are there likely to be lugs built in to the brickwork as well?

We appreciate the hinges may not need to be separated if we can get the glass out in order to sufficiently lighten the whole assembly, but we are restricted for time as the builders want to work in the space, and clearing up all that broken glass looks like a lot of work.

Regrettably there is little room in the planned new arch for the wood framed sidelight.

Hi benawhile
From my recollection the hinges are held together with a riveted pin. Suggest you lift the doors as much as possible and cut through the centre of the hinges with an ultra thin cutting disc.
The metal frame will be fixed to the timber sub frame with the screws but it's probable that putty will have been used in the join and this will now be like rock. You will probably have to destroy the wooden sub frame to clear the brick opening.
