I have a problem with damp in my bungalow. One wall which runs the entire length of the bungalow (living room and our bedroom) has damp on the wall inside. It has caused wall paper to flake off, skirting to become soaked and the wall is damp to touch. On the outside there are white powderery deposits on th bricks just above the ground but below the dpc. The ground level is only about 100mm from the dpc. Plus in the bedroom there is also 2x dark patches on the ceiling right in the corner and just away from the corner slightly that are both blackened. This bungalow was built around 1970. I also have damp coming in around a back door which is a new extension. We had the builder back not long afterwards since the brand new carpet just inside the door was getting wet. The door frame and wall next to it have also become black with mould (which I have just cleaned off). The builder said the ground level was possibly too high outside the door and hence why the water was getting in through the bricks (???). I dug it out about a 8" but still we get some mould around the door frame and a damp carpet. Can anybody please confirem about the ground height and also offer any suggestions as to what I could check or test?
