Damp problems usually happen on properties without any prior warning and can cause serious structural damage to your property. To identify damp in your property, there are a number of signs you can look out for, such as if there is it damp musty smell, blackspots with mould growth, if your wallpapers appear discoloured and detached or your skirting boards are brittle and broken. These are common signs that your home has a damp problem.
