We will be in touch
We have had this mid terrace house for about 10 years with no damp problems, however for the last 2 months it has been empty with the heating on twice per day for 1hr each time.
That wall for some reason has started getting damp. The kitchen door had been shut by the estate agent and the kitchen is not heated, so I could partly understand if it was just the kitchen wall with condensation because of the difference in temp between warm house and cold kitchen, but its the longer wall too.
Any ideas how to solve it?
Edit: we have put that radiator in as a temporary measure to try and dry it out.

Something leaking?
Can't help with the damp, but I'd get rid of that weird window.
Have you checked that you haven't got a gutter leaking onto that wall? We had a similar problem quickly fixed with the gutters repaired and aligned.
is the floor wet,
Rising damp given the level it's at?
Re water. The only external window is to the right of the open door so I would be surprised if water was tracking past the doorway.
Floor is dry...
Can you see any damp in a similar location in the kitchen?
Is that a party wall and do your neighbours have a similar issue?
The heater won't do much, get or hire a dehumidifier to dry it out
what is the floor, suspended or solid
As said dehumidifier needed, also you need to check what's on the other side of the wall and what's going on below, check the roof, gutters etc, you certainly have rising damp there, you have to find the source and stop it there,
I'm no expert but have had to deal with rising damp plus wet rot and dry rot when I bought my house, I gotta say that looks quite a lot, bet it smells all musty .. Yuk
With all the rain we have been having it may even be the ground beneath the house is waterlogged and the damp course is either non existent or failing ,
I've had to do a valley in my house in December to stop a leak in the roof and now I have paint falling off my ceiling in the end of the kitchen above some French doors,
How olds your house OP ?
Do you have a extract in the bathroom perchance in the ceiling??? Ive sin many fed up into loft and the condensation builds up in roof space and runs down walls causing damp, or neighbours have any leaks/problems ??
It could be coming in at one point and soaking along the skirting. Not that that helps much in the diagnosis but it could be a small point source.
Is there any ventilation in that room?
That's serious damp (sorry for stating the obvious).
But it doesn't look like damp, how can a wall become that damp from moisture in the air...It can't.
Get someone in.
Why not just leave the heating on low...?
Probably cost less than coming on & having to work like mad for 2 hours a day.
You need the carpet up & check the floor.
I doubt you had the problem when you lived there, that looks bad enough that even having heating on etc wouldn't mask it.
I'd be checking for a leak from somewhere, external or internal.
inclined to think it a leak, possibly drain under the corner, do you have buildings insurance
leak
Rising damp given the level it's at?
It's widely accepted that rising damp doesn't exist and is something spouted by 'damp specialists' to sell expensive, unecessary and pointless treatments into your wall.
has the heater been placed there to dry it or was it always there?is it damp to the touch or just stained?have a simalar heater on a painted wood floor and has caused what looks like a damp patch,but its just stained.it does look like a leak though
Why is it worse on that kitchen wall? Does it run all the way along the party wall to the left? Is there any pipework inside the kitchen wall?
Loving the pretty evil looking damp issue - then plugging a high load appliance into the socket directly below the damp patch.....
Just sayin...
Fwiw it looks like alot more than condensation - you would expect the damp to eminate from the window more than than the floor as condensation would form on the window first.
