Condensation can affect a property of any age and be caused by several factors, the main one being the lifestyle of the occupants. Examples of these are not keeping the property at a constant temperature during cold weather and not ventilating rooms after cooking, taking a bath or using the shower.
The major building defects that can also cause condensation is insufficient insulation. This can create cold internal wall or ceiling surfaces, which become wet when the occupants increase the level of humidity. In winter months high humidity affects one in five of all British homes and 75% of damp problems that affect property can be attributed to condensation. If not effectively controlled, it can cause damage to property, clothing and personal items, as well as being a serious risk to your health.
What is condensation?
Condensation occurs when warm, moist air comes into contact with a cooler surface, such as a badly insulated window or wall. This causes water droplets to form on the cold surface, which over a short period of time causes Black Spot Mould to form, damaging decorations, plaster, furniture and clothing. Warm, moist air is produced from everyday activities like bathing, showering, cooking, dying laundry indoors or even boiling a kettle, all of which add moisture into the atmosphere in your home. To create a healthy living environment, the high humidity has to be controlled or extracted continuously, by the occupants and suitable control equipment.

Do you have condensation?
If you have very damp walls, black mould, misted windows or puddles of water on your window sills then the humidity in your home is far too high and causing condensation To reduce this humidity and limit the damage to your property and health, it is very important that you personally carry out all of the measures recommended by us and continue doing so, throughout the colder weather.
Studies suggest that the spores given off by black spot mould (Aspergillus app) may be inhaled and lead to cold-like symptoms including coughs, sore throats, red and sore eyes, a running nose and migraine. Other studies have been even more extreme and suggest that some people living in a damp home may also experience more serious respiratory problems, such as asthma.
How we control condensation?
Our qualified damp surveyor will carry out an inspection and take surface moisture readings using a damp meter. He will also take temperature and humidity readings using a ‘Hygrometer’ and wall and ceiling temperature readings using an ‘Infrared Thermometer’. Based on these readings, calculations will be made to determine the ‘Dew Point’ (the level at which humidity turns to water) and what control methods are required to prevent it. It is likely that our recommendations will include a change of lifestyle by the occupants, together with any additional methods we recommend. Depending on the extent of the problem, some of the measures we may recommend are insulating the internal surfaces of the walls or ceilings, increasing the extraction of moist air in the kitchen and bathroom, installing a cost efficient, thermostatically controlled Condensation Control Unit or installing Passive Vapour Vents. Most systems can be installed by our technicians in just one day and start working immediately. Details on what is causing the problem and what is required to control it will be clearly set out in our comprehensive report.
