Ok so i had new front and rear doors fitted a couple of years ago. The rear has an alu kickplate and its acting like a cold bridge causing significant amounts of condensation and damaging the floor.
Ive asked the supplier if they can swap it out and apparently not because the door ws a custom job.
Is there any way i can solve this issue?
Can the internal kick plate be removed?
it seems to be one piece across the threshold.
Not the thread I was expecting...
Thermal pants?
Stick some insulation over it?
talc?
yup ive considered that. Im just wondering if theres any other suggestions to stopping my back door rim dripping.
Your rim may be damaged by overuse. Have you considered not going in and out of it quite so often?
its like new. just wet
As all the funny answers have been taken, I'll attempt a sensible one:
You're getting condensation (I assume) because warm, moist (stop it) air inside the house is hitting the plate, which is cold cos of conductance to outside. Can you stick/attach something insulating to the inside face of the plate so there's no cold surface for the condensate to form on? Like a thin wood/laminate/fabric/plastic panel or similar?

As others have said, it is cold bridging and possibly a slight draft.
Our front door does it (wood, single glazed) at letter box, handle, threshhold and of course the glass. This morning it was frozen.
Pop a rubber (oo-er) draft strip (chortle) on the bottom (s****) of the door, possibly a small one sticking up (snort) from the floor to overlap the one hanging down.
We use a curtain over the whole door.
I assume it's the narrow strip across the bottom, which is attached to the floor? I'd go with a strip of laminate or wooden edging the right depth/width and glue it to it, either something that matches the floor, or white (painted if necessary) to match the door.

Best answer so far.
Joking aside, that seems like a lot of moisture for just gathering on a rim strip. It's the quantity I'd expect from the entire surface of a cold window.
Is it condensing somewhere else within the door unit itself and running down to that point? In which case sealing up any gaps allowing moist air to enter the door panel might help?
Also I'm guessing this is a kitchen or maybe somewhere you're running a tumble dryer - how is your steam extraction?
such as


my concern is that fixing something such as that may hide the condensation behind it so it doesnt evapourate.
Yes its a lot of moisture
That does seem very wet. Are you sure it is just condensation from that tiny surface? Mine was about that wet when it was leaking. Just a little bit of silicon missed on the install. Easily fixed but I did need to take the door frame out to do it.
It is condensation on the aluminium threshold. We had exactly the same problem, even got the same door mat! I tried sticking on some of the neoprene insulation that I had left over from my solar water project, which solved it partially but condensation still formed wherever there was cold metal and in the end the neoprene got kicked off by feet. The answer was to relocate the tumble dryer to the garage and stop drying clothes in the utility room.
If you're sure it's not water being blown in under the door (are you well north? we haven't had that many days when it would get cold enough for condensation) then I'd try sticking some duct tape to the aluminium.
It will give it a warmer surface and the warm air might not be able to get underneath to the aluminium.
