Water Ingress in door sill

[85stu]

I've recently bought a house that had damp proofing redone. One of the back doors has always felt very stiff as if the wood along the bottom or the doorframe has swollen slightly. It's raining heavily today (I think the first heavy rain since we moved in) and I've noticed some ingress in the bottom corner. The plaster has gotten very dark.

Photo attached. Haven't opened the door to investigate yet, but if anyone has advice on what to look at first it would be appreciated.

I opened the door to get a look at the seal in the corner.

Door threshold trouble.
Looks like you need to fit a door threshold seal strip suitable to keep water out then look again in summer for longer term solution

So I think the door already has one on the outside. There's a lip at the bottom on the external. Could it simply be damaged underneath?

The image isn’t clear enough, but it looks like the water bar is missing from the cill - does the cill have a groove in it?

Got a better pic of the seal/theshhold. Looks to me like the seal is maybe damaged?

I'm about to go away for a week and keen to not leave this lying as it is expected to rain heavily in that time. Failing a proper fix in the next 12 hours what can I do to stem the tide for a short time? Decorator's caulk around the base of the door frame to attempt to seal it? Duct tape? Stuffing somewhere with kitchen paper?

I'm assuming there's some sort of weather seal/strip attached to the underside of the door? Otherwise judging by the most recent pic you posted, the underside hasn't been sealed from the elements at all.

If you have time tomorrow (you say you have 12 hours to fix it?) and the skills you could fit a door threshold bought from somewhere like Screwfix or B&Q. If you don't have time, you could maybe stuff the gap underneath the door (and a couple of inches up either side if there's space) with something like rolled up plastic bags, pushed into the gaps with a screwdriver or something i.e. tightly packed. Then put a folded up towel or two against the bottom of the door.

Won't have time for that unfortunately. Have stuffed a bin bag under the door and put some heavy duty tape over the top of the weather bar in case it is getting in from the top. Will review in the morning.

Tape a sheet of plastic on the outside to throw off rain.

It looks as though some of the wood (inside the frame etc) hasn't been treated in any way, maybe just a trick of the camera. If it hasn't been treated, when dry, it would be a good idea to get 2-3 coats of something on it to protect from the elements.

I didn't quite mean to do the plastic like that, however if it's tightly packed underneath it'll do the trick. Also try to ensure none of it is poking outside.

Some duct tape over the outside gaps/joins would help too.
