Condensation problems are another type of damp problem which is greatly overlooked because people don’t understand it or notice it because high humidity (warm damp air) is causing this to happen and condensing back into water vapour every night after the heating goes off and the walls get cold again.
Condensing back into water droplets on the same part wall every day will start to draw moisture through the wall. This continuous action will cause the hydroscopic salts in the building material to start to cause stains in the wall which look wet and like rising damp and penetrating damp. When at its extreme it will look like rock salt coming out of your plasterwork especially if the wall has been re-plastered with pink gypsum plaster with a sand and cement render backing. Again wrong materials in old houses it doesn’t breathe and let moisture through the wall to evaporate.
Condensation is caused by excessive indoor humidity which is created by us living inside the property. Every day living for a family of 4 includes cooking, breathing, drying clothes, washing up, baths and showers, washing machine, kettle, plants and pets can create up to 12 litres of water vapour a day.
Condensation Problems on Windows and Walls
This vapour has to go somewhere so its effects appear on and around cold surfaces such as windows and on walls near the skirting boards. The reason it affects the lower wall is because this is where the wall / floor come together and is the coldest part of any internal wall.
Ceilings also suffer from condensation and will attract speckled fungal growth. Other common places to find heavy mould growth is behind bulky furniture and unventilated cupboards where there is no air movement.
Condensation Health Risks
Excessive long term humidity will affect clothes and carpets which will smell musty and will be damp to touch due to excessive mould spores this is not a healthy option.
With increasing energy costs sealing up old houses to prevent all draughts has become the normal thing do but this is trapping lots of moisture in your home on a daily basis. With no outlet for the moisture this starts to cause musty old smells, clammy plaster and black mould spores, which start to drift around the house settling in cupboards and on your clothes
Damp and Mould Health Risks
These damp conditions long term can exacerbate bronchial and asthmatic conditions due to excessive damp conditions in bedroom areas.
Aspergillus Niger and similar moulds are hydrophilic fungi; that is
they require high levels of surface moisture. Capillary held dampness is not sufficient to cause mould growth. The mould requires free moisture on the surface.
Condensation Problem Cures
Condensation can be reduced by regular heating and improved frequent ventilation to the property. Building regulations today insist on extraction in Bathrooms and kitchens.
It is recommended that extra ventilation is introduced into the property by installing bathroom/kitchen fans and the installation of a positive pressure unit to the property.
We can assist you in a selection of British made fans with 3 year guarantees that can adequately remove you excessive moisture levels and have them set and install by a professional qualified electrician.

Condensation and Thermal Bridging
It is a well-known fact that warm air will hold far more water vapour than cold air. A well-insulated room can be very humid especially rooms like kitchens and bathrooms. In some properties this won’t be a problem but in older houses if this humid air leaks through gaps in floors, walls and ceilings then when it comes into contact with a colder surface it will quickly cool down and condense back into water. If you have lined your walls then the wall behind will now be colder. And any humid air that manages to make contact will condense back into water and start running down the wall to wooden floors and joists and remain trapped within the building. This type of damp is known as interstitial condensation. Now because this damp can go unnoticed for long periods serious decay can take effect.
Damp from condensation will also effect areas where insulation has been missed or it isn’t thick enough this will cause thermal bridging. This is where the outside cold air will penetrate the building. The normal cold spot are around reveals around the openings for windows and doors and the upstairs ceilings near the eaves.
