Catching damp early will help you deal with it more easily. To spot damp before it grows into a larger scale problem you need to know where to look out for it. A good place to start is your walls, hold your hand on the wall and look for patches which feel cold or damp. Curling wallpaper and flaking paint can also be a sign of damp which is visible alongside specks of mould. For your ceiling look for discolouration particularly next to external corners. Bathrooms and kitchens are other prominent spots for damp and mould. Check the ceiling and walls as described above as well as grout and inside cupboards. Condensation and puddles of water on your window sills could be either a sign of damp or a potential cause. Mould can appear on window frames and on the sealant used around their edges.
