Trimming Internal Door

Gday all,

I have an existing door frame that is 810 wide but the only door i could find was 820 wide.The door is to used in a home office, so privacy etc isnt really that big of a drama, it is more for decorative and occasional use.
The door manufacturer recommends a maximum 3mm off either side....still leaving the door 4mm too wide.
Replacing the frame is not really an option i wish to pursue.
I dont know how wide the stile of the door is but will shaving the extra 2mm off either side make that much of a difference to the door in regard to strength, hinges etc.?

Many thanks in advance.

shouldn't matter if you take it off each side evenly.

Most doors have up to 30mm of timber each side. You can usually check by looking at he top or bottom edge of the door.
Taking 4 or 5mm off one side would be considered a minor adjustment.

The manufacturer's recomendation of 3mm maximum trimming allowance leaves a safety margin so you won't hit the nails/staples the framing corners are held together with. You can probably go 5mm off a side without hitting any fixings, but be aware that you may. Don't use the handplane you've just spent hours fettling, shaprening and honing as this will guarantee you'll hit the fixings :rolleyes: .

If you haven't already bought the door you could always buy a solid core door and then it wouldn't matter how much you took off it.

I think Corinthian hollow cores allow a 5mm trim all round.


Cheers...........Sean, shut the door on your way out...

I had a very similar issue with some hume doors I purchased. I purchased 720's but the door's need to be 710.

I ended up taking 5 mm off each side, I think I could have take another 5 mm off each side...but didn't need to.

I used mu GMC planner with after market TCT blades, taking 1mm off in each pass. in one direction and then the other.

Corinthian do recommend taking no more than 5mm off each edge (which would leave you with your desired 810). If you have purchased a cheapie you may unfortunately leave very little frame for stability if you take off too much. I can't imagine the extra 2mm off each side will matter but if something does go wrong you've given the manufacturer an out.

Doors generally come in standard sizes (2040x820 (most common) 870, 770,720 [usual size for toilets] etc. as well as higher: 2340x820 for example) and you trim them down. If you require more than the allowed 5mm off each side (for Corinthian, Hume etc). you can order doors with additional widths on rails and/or stiles. As already mentioned you could always go for a solid door, though if it is internal I would recommend using three hinges (as you would for an external).


Cheers,

get a blokdor - I think they are from corinthian

Solid doors have a chipboard centre section and timber edges

blockdoors are laminated timber "blocks" throughout so you can cut them whatever size you like

they also come in a 2100 height in case your aperture is out of square when renovating

but remember to use 3 hinges - they are a bit heavy

Many thanks to all that replied.
After looking at the base of the door as suggested by a fellow member.....5mm was ok with plenty left over for stability.
By the way dont ever email hume doors and expect a reply.....reply?.......whats a reply.
Once again many thanks to all.
