Condensation Advice

During the winter months, many properties suffer from damp and mould growth due to condensation.

Below you will find some information to be used to identify condensation and in our advice leaflets you will find some preventative measures you can take.

Condensation is often confused with rising damp. The advice given should help to distinguish one from the other and by following our identification and control hints you should be able to combat many condensation issues.

Causes and Signs of Condensation

Air can hold moisture; the warmer the air, the more moisture it can hold. If moist air is cooled by contact with cold surfaces such as walls and windows, relative humidity increases and the moisture can condense into water droplets (condensation). Mould regularly occurs as a result of this high humidity. Mould often appears as black spots or areas, usually on the surfaces of external walls, in corners and in poorly ventilated spaces, such as behind cupboards and wardrobes.


For a full checklist and advice on combatting condensation we strongly advise you look at the attached advice leaflet and implement some of the factors to reduce condensation problems.

Positive Input Ventilation

An additional measure is a Positive Input Ventilation unit (PIV) fitted in the loft space that will use warmed air from conductive heat within the property.  This will provide clean air that will significantly help reduce the condensation of atmospheric moisture on internal walls and windows and will provide a fresher feel within the property.  Running costs are typically in the region of £10 per annum.  Most units have an adjustable setting so can be controlled depending on humidity generated in the property. A reputable qualified electrician would be able to fit one of these units.

We do not fit these but can recommend them if we feel they are a suitable solution to condensation problems.
