Non standard width internal doors

[Andy46]

Hi,

Any idea where i can purchase internal doors suitable for a space which is 1980h x 780mm wide please? Most sites seems to sell either 760ish or 830ish. The 760 isn't wide enough and the 830 ones say they can only be trimmed by about 20mm which will still be too big. I presume my door width isn't standard.

Thanks

Adjust the hole, not the door?

By which I assume you mean the door frame?

My internal doors are, in old money 2' 6'' x 6' 6'', which is approximately 760mm x 1980mm which I imagine to be standard. In my previous Victorian house , what had been the 'grand' rooms, for instance an upstairs drawing room, had a rather wider door which would have been around the 780ish, maybe a bit more, probably nearer 790mm or 2' 7''. I doubt that Victorian joiners used anything other then feet and inches.

I suspect a) that it might be difficult to change the door frames and b) that it might be difficult to find a non standard door 'off the shelf'. The 830mm quoted may well be to accommodate a wheelchair.

Be interested to hear from those who know about these things.

I would agree. You can buy bespoke size doors but they are horrendously expensive. Far cheaper to pack out the existing lining and move the architraves in so you can use a 760.

Quite.

It is trivially easy to lever off the door stop, fix a piece of 20mm thick wood to the internal face of the door frame then put the door stop back on again, and hang your 760mm doors in the newly reduced door frame. It even doesn't show up particularly if you don't bother move the architrave! Nobody notices.

The hardest bit of doing this is actually finding 20mm-thick wood. It's usually 18mm nominal in the timber merchant and closer to 17mm after a couple of years and fully dried out. You'll probably have to ask the merchant or a joinery shop to run some thicker stock through the planer-thicknesser to get it to 20mm. Still way easier than getting extra-wide doors made though.

It isn't difficult to pack out the architrave on the hinge side - I had to do it on a Regency/Victorian doorway that was all of 30mm too wide for an off-the-peg door. But moving the decorative moulding around the architrave inward was going to be such a pig that I wimped out and painted the insert piece white, and TBH it doesn't show. (Hey, it's a "character" building, isn't it?) [Edit - have just seen Mike4's comments on the same subject.]

Packing the doorway on the striker plate side would have been far more difficult, not only for the more in-your-face aesthetics but for the strength of the thing. But you might like to check the diagonals before you do anything else, because many of those made-to-measure old doors are well off the rectangular.

Serious suggestion: If it's an old building, consider asking around at architectural salvage yards where they've probably got them in odd sizes?

Hi Andy,

I've no wish to disagree with the suggestions others have made but would offer my opinion based on 41 years in the construction industry. I do specify many of the materials that are used the construction of buildings and have a healthy technical knowledge of many aspects of the built environment.

I would resist changing the size of the doors frame. It's certainly an option though. If you pack out the door frame the new timber laths will need to be well screwed and glued to the existing timbers. However, the existing timber frame will be painted and the paint may create a debonding effect. So the weight of the new door will not be on the existing timber frame but a much smaller new lath. And over time dependant upon the weight of the door it may well pull the planted timber out of shape. I certainly wouldn't use MDF for this solution. You will also have to move or replace the architraves which will add to the costs. It will be difficult to re-use the existing as they will damage when moved and also leave a gap where the skirting board butts up. It will all need redecorating too.

It's certainly s viable solution though as long as you are prepared to accept the risk (probably small) and know that the costs will be "labour intensive". If cost is an issue and you're working to a fixed budget then this will still be more cost efficient than purchasing bespoke sized doors. Aesthetically it won't look quite as good as using a correctly sized door.

Doors in proper money are usually 6'6" x 2'6" internal or 6'8" x 2'8" external. Grander houses may have had 7'0" x 3'0".
Your local salvage yard will have a profusion of offerings. Or eBay.
