Just moved into a house and I've noticed that in one area of the living room , a small damp patch appears on the end of the floorboards against one wall that appears at night but then dries out during the day
I've had a look and found that 3 boards were touching the wall below the membrane dpc so I've cut them back but it still happens
i pulled a floorboard up before going to work this morning and everything looks ok apart from the obvious damp in the wall below the physical dpc
being a noob, can i ask what is the best way to ventilate the area?
i've been round all the airbricks cleaning them out and they're all ok and there's a hole further down the problem area where the gas pipe comes through from the cupboard under the stairs to the gas fire and there's no furniture or carpets in the room yet
the only other thing i've found online about the subject suggests hygroscopic salts in the wood pulling moisture out the air ...but i thought that caused by burning wood or coal?
a copper pipe will have moisture on it, that could be the culprit, the floor area under the boards must be as clean as possible, so air can circulate any rubbish must be cleared. use pipe insulation to cover the pipe aswell
