Door frames not square

[Water]

Morning all, 

 

I'm getting all new fire doors and I went to measure up the door frames and some are +/-5mm in width from the top to the bottom. I think a 5mm gap between the door and the frame is too large to look good? Also I'm pretty sure a bit gap isnt good for fire protection.

 

I can order custom sized doors to the mm but the gap will still be 5mm + a little as the door has to open, I guess the only real option is to sand down frame argh!

 

Not sure if I'm being too picky here?

You can plane the doors to size up to a limit specified by the manufacturer.  Is that an option that will let you use a stock size?  Look at imperial as well as metric sizes to find one close enough.

Why are the frames out of square ..?? Can you not pull the architraves off and have a look at the framing ..? Make them square and plumb and then it should make it easier to put the doors in as standard.

The doors I’m looking at have a 3mm trim on the sides, not sure how easy it would be to alter the doors to fit the frames.
 

Although the thought refitting the linings isn’t fun either. 
 

Especially as it will all have to be redecorated. Damn but there isn’t going to be a non pain in the … way.
