Dampness, condensation, and mould problems

Damp and condensation is a common problem in many homes today, even in homes with modern efficient central heating systems. It can often lead to mould forming on walls and in wardrobes, running windows, and for people suffering from Asthma, poor air quality can be a particular problem.

curing dampness condensation and mould starts with the reight diagnosis

Understanding the reasons for dampness, condensation and mould are essential if the problem is to be solved and an effective remedy put in place. Misdiagnosis of the reasons for dampness in homes can lead to expensive and ineffective remedial work.

How does your home ‘feel’ to a visitor ?

We all get used to the characteristic smells of our own homes, but it’s not until we return from an extended period away - like a holiday - that we get a sense of how it feels to a visitor.

We can also become used to the stale air and humidity levels in our own homes, even when it's far in excess of what would be considered a healthy environment. We all want to make our homes more energy efficient but by taking action to reduce draughts we are also reducing the amount of fresh air coming in.

Condensation on windows Dust mites The link between air quality and Asthma

Condensation is not just responsible for the development of unsightly mould. Certain micro-organisms thrive inside damp buildings, including bacteria, fungi, moulds, mites and yeasts - and all can make people ill. Humid conditions encourage the spread of microscopic dust mites – a cause of Asthma and allergic symptoms

Whether through well intentioned ‘improvements’ or other changes some of the most common problems with old houses that reduce air circulation are:

  • Installation of plastic (UPVC) windows with no trickle vents.
  • Fireplaces blocked up with no ventilation.
  • Draught excluders around doors.
  • Lack of ventilation to cellars.
  • No extractor fans to kitchen and bathrooms.
  • Ventilation bricks blocked up.

Damp walls - rising damp or condensation ?

Many older homes have dampness and mould forming at the bottom of walls. In many cases these have had a remedial damp proof treatment designed to prevent rising damp, which has made little or no difference. Often this work includes disruptive and expensive removal and renewal of plaster coatings when the real problem has been excess humidity and condensation on cold walls in the effected room.
