HI there. I've bought a house which is an Edwardian terrace with a cellar. The rear is a full storey higher ground than the front, due to being on a large hill. COnsequently there's a lot of groundwater moving through the general area and the back of the house is quite damp. The rear room has no cellar below and has a suspended timber floor. I took the floor up in the dampest corner and found a few potential issues. There was almost no sub-floor ventilation as it's full of rubble with one air brick and seemingly no through ventilation to the cellar. But also, there is a clear DPC running about half a brick below the height of the external concreted floor. I've had a surveyor and a structural engineer for various reasons take a look at the place and neither of them seemed that fussed about the DPC being below ground level, but from my research that's a clear and likely source of damp ingress. We run a dehumidifer constantly to see if it will dry out with the boards up and although it keeps the damp smell at bay, the water keeps coming and the dehumidifier fills its reservoir daily. In order to try and improve things I'll be taking out a load of rubble and making a good cross-ventilated sub-floor, but am I fighting a losing battle if I don't sort out the ground level? I have two walls both external in that room and both are raised above the DPC. One was done by the previous owners and one is sadly a shared passage between houses that was renovated by the neighbour without gaining consent.
