Bathroom Advice: Tackling Damp

Damp, a problem we have all experienced, is something that occurs most frequently in older houses. Unquestionably a common problem for home renovators, it’s important to know how to eliminate the issue and work to keep your house damp free. The most common occurrence of damp comes in the form of condensation, easily identifiable when you find water running down windows.

In some cases, water can be found running down walls creating dark mould spots, ranging from small speckles to big patches on ceilings and walls. Getting rid of this mould is vital, as not only does it look unsightly, it can release spores which individuals with respiratory problems can seriously be affected by.

So what causes this damp to occur? In short, the amount of water that is carried in the air varies dependent on the temperature of the environment. Hot air can carry more water than cold air, and with our homes being fairly warm during winter, the air contains plenty of vapour.

Condensation occurs when the warm air comes in contact with cold surfaces such as windows or walls, where the water can no longer be supported. The vapour condenses back to a liquid and remains on the surface. The main causes come down to poor cavity insulation, or insufficient ventilation.

Treating this type of damp is fairly straightforward providing you stick to certain control methods. Better ventilation is a good starting block therefore environments that create plenty of vapour or steam such as the shower room, require an automated ventilation system. Upgrading your insulation on outside walls will also create less cold surfaces for vapour to settle on.
