Better insulation such as cavity wall insulation can help prevent cold patches on walls reducing the risk of condensation problems. Moisture is generated in any house – through washing, cooking, drying laundry and even breathing. To keep your home feeling dry and comfortable, moist air needs a way to escape the building. If it can’t escape, it builds up within the home creating condensation.

Keep an eye on air humidity: "Condensation can be treated by reducing air humidity or keeping surfaces above dew point temperature," says chartered building surveyor Douglas Kent. "Humidity is reduced by cutting the amount of moisture available or increasingventilation. Condensation in chimney flues can be eliminated with proper linings. Redundant flues that have been sealed should be fitted with ventilation grilles or re-opened." As with wallpaper, damp will easily spread through the paint on your walls.

Chemical damp-proof course - chemical solution ( damp-proof cream) injected into the mortar joint of effected walls through drilled holes to create waterproof barrier and prevent moisture rising above the new damp proof course.

In newer houses, there will be a damp-proof course (typically built into a wall at 15cm above ground level) and a damp proof membrane under the floor to prevent water from moving upwards. The two are connected to provide a seal to any water coming into the house. However, many older properties were built without one or either of these forms of protection.

It’s advisable to remove incompatible modern materials such as cement render or mortar pointing that trap damp." Once the underlying damp issue has been resolved, chances are you will need to replaster the affected area.
