10mm from each side might be ok though might only leave < 10mm before
the cardboard. If the hinge areas are not reinforced then it probably
won't work for you.

You can generally check where you can see the change in direction of
grain at the top and bottom of the door.

I would have thought a glazed door would be solid wood BICBW. I doubt a
solid glazed door would cost much more?

The lock areas should have more wood.

What warranty would you need?

Normally doors have solid wood at the edges with a hollow/honeycomb/glazed/... middle, with the expectation you'll take equal parts off each side to make
it fit. Do the suppliers say how wide their edge strips are? I wouldn't have thought taking 11mm off each side would be unusual. If you tried to take
21mm off one side I suppose that might be more difficult if the edging is
only thin.

My only experience of buying doors is sight-unseen from: https://deantawood.co.uk/
- the door was structurally fine, the finishing varnish was a bit cheap looking. I should have bought the unfinished one and finished it myself. Picking a random one: https://deantawood.co.uk/products/internal-doors/oak-doors/coventry-prefinished-interior-oak-door/
it says 32mm can be taken off the width and height (16mm each side I
presume).

I think on the 'oak'/'ash'/etc doors, they're actually made of pine structure but
with oak veneer, including oak battens on the edges. The thickness you can
cut is the depth at which you run out of the batten and into the pine.

The lock areas should have more wood.

Yes, but may be pine and not oak. It doesn't matter for holding the lock
in, but does matter if it's on display.

Back in the day these doors were made of solid wood and it was no problem
to trim off the amounts you are talking about. These days they tend to be particle board (chipboard ) that are veneered if requiring a particular
wood finish or moulded with a foil. Lipping is added to the edges but these days that tends to pretty minimum no leaving much to trim down, one manufacturer I noted limited to trimming to 6mm top and bottom giving 12mm
in total before the inner particle board was exposed. Exposing the core on
the bottom or top edge may not be an issue but can be a problem as my SiL
found when he spilled a glass of water and the water went under a door that
had been trimmed back more than specified. In his case the door swelled and split the outer foil. Fortunetly, it was a new build and still covered by
the developers warranty and they replaced the door as it obviously had been incorrectly fitted. This may explain why the supplier will not honour a guarantee if the door is trimmed beyond specified limits.

The only solution that I can think is trim the door slightly more than
required and add lipping to bring back to the dimensions you require but
this will not preserve any supplier guarantee.

I would say your suppliers are being helpfull by not selling something
that does not fit.

Almost all doors are a honeycomb or similar core with typically 10mm of
lipping round the door. I had this issue with a house in Spain with
short doors and had to have a door custom made.

After a bit of googling I found that Deanta doors allow 32mm reduction
in height but don't see the Pattern 10 you want.

I think you are just going to either order a custom door, modify the
frame, or perhaps use something that isn't pattern 10.

Get a solid door is the obvious answer, but there is an alternative ...
If, as I expect, trimming exposes the core then it's fairly easy to make
and glue-in a filler piece of wood. It's at the top and/or bottom so
won't be visible. If it's an "engineered" door the core will be
something solid (chipboard?) and the filler piece won't be needed unless
you want to route out a piece so you can let-in some hardwood to match
the facings.

"The core" can vary depending on the type of door. Some will be egg box
style doors with solid wood strips only at the perimeter, and (usually) cardboard grid glued in between the panels. The edge strips are usually
deep enough to fit hinges and create a strong frame for the door.

Another type is the "engineered" solution with a MDF or chipboard core,
and then slim lippings on the edges all round. The lipping may only be
quite thin (say 6mm) - enough to make it look like a hardwood, without
actually needing to use much hardwood.

The former are easy enough to work with if you need to chop off all of
the wood strip on an edge. You can just push some of the visible
cardboard spacing out of the way, plane up a bit of timber to the right thickness, glue it up, and tap it mack into place.

The engineered ones will just expose the core. On the sides where this
is visible that would not look good - so you would need to cut off 6mm
more than required on each side, and glue on a new lipping. (where the
new lipping could be the original one that you cut off first - in effect
take the edge off, then a bit of the core, and stick the edge back). If
the edge you need to cut more deeply is the bottom, you might not care
what it looks like, just seal it with something and be done with it.

Anyone got any thoughts on this and/or a link to a more helpful supplier?

This is more of a product limitation rather than a supplier being
difficult. However since you probably don't care about the warranty
anyway, does it matter if you void it?

If you don't mid hacking cheap doors about a bit they can be quite a
good source of material for projects... For example, I had a request for
help doing a 6' wide L shaped shelf that was to run at a high level
above a computer desk. The deepest bit was about 3' dropping to 2' for
most of the width.

The easy and cheap way to do it was to buy a basic "pre-primed" egg box
door from wickes, hack it about and refit edges. Then plant an
additional wide edge on the front facing bit to allow a roundover to be
routed onto it. The result was pretty good - lightweight, strong, and cheap:

The long sides are OK, it's the short edges which need reducing to get
the height down to 1960mm: 1981 -> 1960, so 21mm to take off spread over
each short edge.

As John Rumm says, cut it down and patch it up. In fact the width is not
a problem - 2mm only. You won't ever see the top or the bottom edge of
the door so if you have a solid core door just cut it down. When you
have finished trimming and sanding maybe seal the edge with paint or
varnish, that's all you will need to do.

I got a couple of glazed veneered chipboard doors cheap, and cut them down
well into the core. Looked to be a very sturdy frame, mitred and glued - and very heavy. I screwed in metal plates across the joints, although I doubt they'd do much.

They may fail, but hey - £30 the pair on ebay.

He only need 1mm from each side to get down to 760 from 762. The 19mm
top and bottom may be more of an issue.

One specification I've seen suggests that only 6mm* can be trimmed from
each edge. On a pattern 10 internal fully glazed door the top and bottom
bars are not the same height. The top seems to match the side width and
the bottom much higher in height. Trimming more on the top than what is
trimmed off the sides may not be cosmetically pleasing.

*
Wickes a total of 20mm from the height or width but other manufactures
state, where the lipping size is given, say 10mm lipping and 6mm trimming.

However, if all the trimming is at the bottom any internal fill is
unlikely to be seen. The inner may not be honeycomb cardboard but MDF,
ply or chipboard.

I would say your suppliers are being helpfull by not selling something
that does not fit.

Almost all doors are a honeycomb or similar core with typically 10mm of lipping round the door. I had this issue with a house in Spain with
short doors and had to have a door custom made.

After a bit of googling I found that Deanta doors allow 32mm reduction
in height but don't see the Pattern 10 you want.

I think you are just going to either order a custom door, modify the
frame, or perhaps use something that isn't pattern 10.

Since the bulk of the trimming is off the bottom, it ought not be that
not that complicated. Cut it where you want, cut a new bottom strip the
same width as the gap between the faces, apply glue, tap into place
flush with the bottom. Run a block plane or some sandpaper along the
sharp edges to finish it off.

I needed a bunch of small non standard sized doors when doing access
doors to the remaining loft space when I did the loft conversion. I just
go a couple of plain egg box doors, and chopped em into the sizes I
needed, then fill the gaps in the cut edges as described above. They
came out fine:

It may be easy to retrieve the lapping strip from the piece that has
been cut from the bottom of the door.

As the bottom of the door will not be seen you may get away with just
using smaller spacers to keep the laminate front and back apart.

Get a solid door is the obvious answer, but there is an alternative
... If, as I expect, trimming exposes the core then it's fairly easy
to make and glue-in a filler piece of wood. It's at the top and/or
bottom so won't be visible. If it's an "engineered" door the core will
be something solid (chipboard?) and the filler piece won't be needed
unless you want to route out a piece so you can let-in some hardwood
to match the facings.

I did see an engineered door with a chipboard core so that may be a
less expensive option though I'll pay a visit to the local joiner.

A door made out of pine would probably shrink and split It really is the most awful material.

None of those that I have fitted have done that. Some are 30 years old

Can you just buy a fire door blank?


Thanks to the solid core construction, this plywood doorway can be
trimmed as much as is required from the bottom and sides, making it easy
to achieve a bespoke fit.

I'm just giving an indication of how you may find a more solid sort of
door. You may be able to get fire doors that are glazed?

The trouble with most fire doors is that in order to have the necessary

fire resistance they need to be 44 MM thick so won't fit in a standard
frame, which is designed for a 35mm door and I assume this is what Frank already has...

You can get 35mm fire doors (I have one) but i don't recall Frank saying
he wants one, someone else introduced that thought?

A couple of us have given the easiest solution: cut a bit off the door
you want and glue something (perhaps the original bottom filler) back in
the gap. Couldn't be simpler, or faster.

And a fire door will fit a standard frame - the door stops[1] need to be positioned further back in the lining, and also need to project further
from the lining to retain the fire performance. You also need (at least)
three fire rated hinges.

[1] Ideally you fit the stops after hanging the door when doing second fix.

In my case it's a fire door, but doesn't need to be, so no fancy hinges
or intumescent seals, I just wanted a heavier door for sound deadening.

10mm from each side might be ok though might only leave < 10mm before

He only need 1mm from each side to get down to 760 from 762. The 19mm
top and bottom may be more of an issue.

Well I have done that (at the bottom), and I just used my bosch
power planer to trim down a suitable length of timber to be a snug
fit into the gap between the front and back leaves of the door
and just scraped out some of the egg box stuff, abraded away the
glue remnants that fixed the egg box in place and tapped the new
bit of timber in with some PVA along the mating faces and clamped
it up.

Yup often a way of getting a decent heavy door for less than a cost of a engineered hardwood one. Worth sticking 3 hinges on though even if not
fire rated, since they are quite heavy usually.

Thanks all for the suggestions: appreciated.

I've found Deanta doors that are solid and allow 32mm to be taken off
the height and the width.

Ahem. They are not solid *wood.* They have a 'PB' core - whatever that
is. Particle board?

Likely. The ones I bought from them are super heavy - maybe 30-40kg for a solid door. I think they are chipboard inside.
