Cold and musty kitchen cupboard

Willowpop

Hi guys, the corner base unit in my kitchen is really cold when you open the door and it smells damp.
I have had a look as best as I can and can't see any holes going through the wall and all looks good on the outside of the flat as well.
Is there anything I could line the inside of the cupboard with that might insulate it a little?
I can't think of anything, but it would be really good to get rid of the damp smell and cold if possible....I dont like keeping any opened food in there because of it.
Any thoughts folks? It seems to be limited to just this corner unit and there are no water leaks from pipes etc.

I have bought one of them little dehumidifiers…the sort that you can buy for a couple of quid from home bargains and similar shops. It is in the cupboard, along with a bowl of bicarb of soda.
Will see how they get on.

Does the unit have a proper back on it or is it just open to the wall.

If the latter does the plaster feel wet or damp to the touch. Could there be a slow leak nearby that is pooling in this corner, check nearby appliances such as washing machine hoses etc. Could water be running down the back of the cupboard from the worktop.

If the cupboard is open to the wall and everything seems dry and there is no evidence of new leaks you could perhaps cut a piece of insulation board to size and attach it to the back of the cupboard or against the outside wall. Or perhaps the silver foil stuff you use behind radiators. That might be easier to manoeuvre into place.

We attached the foil stuff to the back of a cellar door - made a huge difference.

In the meantime the bicarb and de-humidifier should help the cupboard dry out.

Thanks for the advice...There is a back on the cupboard, but only a partial one so there is a bit of it that is open to the wall. I have had a feel and nothing feels damp, the wall feels cold, but not wet.
I think I will try what you said and see if I can close the gap with some sort of insulation and that, along with the bicarb and the dehumidifier may do the trick. I have washed the casserole dishes etc that live in the corner of the cupboard and had damp on them, so it's nice and clean in there now.
Thanks again.
