Hi, since moving into our house 18 months ago we have noticed damp at the bottom of the 3 interior walls under the stairs. The damp shows through on the other side of the walls in the dinning room and front room.
This morning I decided to take of the skirting boards and lift the floors boards to see if it was a leak on a radiator pipe as all 3 walls each have a radiator on them and the pipes go under the floor.
I did not find any leaks on the pipes as all the insulation around them seems pretty dry, but the ground under the floor boards is very damp. It does not seem to damp on the opposite side of the room next to the exterior wall.
I will upload pictures. Any advice as to what might be the cause of this and what (if anything) can be done without spending thousands of pounds?
unfortunately the floor area is so shallow that air cannot circulate, to dry out any moisture. It would be best to remove all the wood flooring, insulate, add a damp proof membrane and concrete. It will not improve unless that method is implemented
Hi A few years ago we did exactly as Welsh brickie suggested to deal with standing water under floorboards (work done by reputable builder). Very satisfied, but hoping you could advise with issue around chimney breast. (We've been putting off dealing with it!) Seems obviously damp and it has been spreading, with salts blowing the plaster in places. Wondering if concrete has bridged the damp course in the chimney breast foundation? Can I solve this relatively easily?
