Condensation Problems

Not All damp problems are caused by rising damp.

The form most common for unwanted dampness in buildings is water from the air that forms as condensation. This Condensation may lead to black or grey mould, damp clothes and an unhealthy environment in your home.

The air in buildings can have a higher level of relative humidity due to the occupants’ activity. Examples of this are cooking, drying clothes, and, yes, even breathing. When this water-loaded air contacts cold surfaces such as windows and cold walls, it can condense, causing water to be deposited. The point at which water held in the air changes from vapour to liquid is called the dew point.

Condensation In Colder Months

Condensation is most associated with poor heating and ventilation in buildings. It is more apparent in the colder winter months, as the external air temperature is low and exterior walls and windows are cold.

The usual events are as follows:

  1. Cold air enters the building
  2. The air is warmed for the comfort of the occupants
  3. The warm air takes up moisture
  4. The warm, moist air makes contact with cold surfaces, walls, windows and is cooled below its Dew Point
  5. Condensation occurs as excess water is released.

Worst Affected.

Walls in bathrooms and Kitchen areas where moisture levels are usually at their highest tend to be worst affected. Areas like solid external walls, un-insulated solid floors and cold bridges such as concrete or steel lintels set in cavity walls are the location commonly where condensation occurs.

Heating Issues.

Properties, where heating is used intermittently, can exacerbate condensation problems as this allows warm, damp air to cool, reducing the capacity to hold water. As a result, dew points are reduced, thus allowing condensation to occur. When air is reheated, water is taken back into the air to be deposited when the temperature drops again.

Condensation Problems and Solutions

Improved Heating and Ventilation coupled with a specific action with colder spots will usually result in a significant improvement in conditions.

Extractor Fans

The installation of extractor fans in the moisture-producing rooms of a property such as a kitchen, bathroom, and en-suites will help remove the large proportion of this moisture-laden air from these areas with minimal running costs. These installations are a requirement within the Building Regulations for new properties being built while also applying to existing buildings.

Sub Floor Ventilation

It has been an observation of many that one of the biggest causes of damp is inadequate ventilation in subfloors. This results in the formation of mould and damp which spread to the entire property, affecting the structural stability. That is why damp proofing is so very important.

Here’s How We Help

We implement highly advanced damp proofing techniques that ventilate your property. We do so by introducing a number of vents and improve the ventilation of the property naturally. If natural ventilation does not prove to be sufficient, we install subfloor fans that improve the air circulation considerably, by pushing out the damp air present within the sub floors and drawing in fresh air from outside.

The vents and fans that we introduce in the sub floors are of the highest quality material. Also, the fans used by us require no maintenance whatsoever.
