Internal door hanging tolerances

[Goldfish707]

Hi, I'm currently having a difference of opinion with my new home builder regarding the gap left under their newly internal hung doors which Are 3/4" higher than the floor.
Is there a code of practice or BS/EN to which the doors should comply?

For heaven's sake, don't kill them or JD will post a thread about it.

20mm is probably around the average to allow for decent underlay and carpet thickness and still allowing the door to swing freely.

Might be better to post in carpentry - mods asked

Sounds fine to me unless they know you are having a thin floor covering?

 

[Goldfish707]

3/4" is after the floor covering has been laid!!

Far too high in my opinion.....once the carpets are down, that is.

Too much IMO too. Should give sensible clearance above carpet so it doesn't drag.

 

[Goldfish707]

Far too high in my opinion too as it looks like they're flapping in the wind. Trouble is builder is just acting dumb so I wanted to use some formal guidance to reinforce the point??!!

I could be wrong, but I would doubt if there is any standard as such. Mostly what you are going to get here is opinion which isn't really going to be that much use if the guy is being difficult.
Someone who hangs doors regularly might come along and tell you what is considered normal.

i allow 12mm when i done house bashing.
when hanging doors in a furnished home,i would try to get the door to brush the pile of the carpet.

I think there are two to consider

a) common sense
b) craftsmanship

Sounds like both are wanting

the only recommendation as such is 12mm under a bathroom door to allow the fan to work efficiently
when hanging doors i go for 3-6mm dependant on door lean or floor rise

If the house has a ventilation system, that gap is ideal for allowing air to travel between rooms. A 5 mm gap on a 736 wide door is about the same area as a 63mm flexiduct (small as they come), but by contrast you need 24mm on a 736 door to be the equivalent of a 150mm duct

It does indeed.
I should have said "official" standard.
The two you mention should be a given if the OP is employing professionals.

I don't know much about ventilation, but surely in a house with a proper ventilation system there would be proper in and out vents? Leaving a gap like that under the door is pretty ugly IMO, and reminds me somehow of in "Steptoe and Son" when 'Arold fits central heating to the house and runs pipes under the doors to warm up the draughts!

I would expect wooden thresholds under all doors. But there again I'm used to old fashioned , decent quality of construction
