Internal doors - ideas/expertise for large trimming

[ClockPie]

Hello experts

Old cranky house and looking at changing internal doors - I think the current doors are B&Q type solid pine so have been trimmed quite a lot to fit.

Looking at oak doors which say "solid core" so not the paper type (so cutting off bottom, removing some core, and gluing back in isn't possible).
eg https://deantawood.co.uk/products/internal-doors/oak-doors/ely-prefinished-interior-oak-door/

Says 32mm can be trimmed, so 16mm each edge/top/bottom.

But I need to trim a couple of doors 50-55mm in height so a little screwed! What happens with a solid core door if you exceed it? Is it just cosmetic?

One in width I need to trim 38mm - and that I think is more problematic as the edges will be seen and I guess too much would weaken the hinge mountings. Only option I can imagine is getting a smaller door width and adding width to the existing casing.

(Casings are painted, the doors we want in oak finish)

I have emailed the manufacturers but imagine they are tied to what they can say, so asking here for expertise, comments and other options that I'm not aware of

Thank you

Hmmm, I've look at the spec for the doors you've stated. The lippings are 18mm thick each side.

Solid core Veneered doors have a chipboard core of varying compactness.

I would not plane 16mm off each side of these doors especially on the hinge side because chipboard doesn't hold screws very well whereas oak does.

You can cut the top and bottom of the door past the lipping, but you will either have to pva the cut edges to seal or better still buy 50mm oak Veneer on a roll and glue the Veneer back on to seal the edges properly.

I strongly recommend you find a carpenter/joiner to fit your doors. Normally in instances such as yours I cut the lippings off reduce the door width by removing the appropriate amount of solid core both sides and glue the lippings back on - this requires experience, but then Veneered doors aren't 2 a penny!!.

In terms of shaving most of the hardwood lipping off the hinge side, I wouldn’t be too concerned. I’ve had to do this in the past and I simply strengthen the area of the hinge screw by glueing a piece of 10mm oak dowel into the core for each hinge screw.

Thanks - idea stored

Personally I would definitely adjust the casings - I know I could manage that with my fairly basic skills/tools.

Reduce door lining to fit a smaller door if possible or change door choice.

The height isn't anything I can do anything about, I may have to exceed the lipping and re-edge.

The width issue doors is an awkward bespoke setup, but it should be possible to narrow the casing by 15-20mm without it being a problem, and then get a 711w door trimmed correctly.

Could change door choice or indeed get bespoke, but you know how these little projects to just change a door or two escalate....
