Ventilation and Condensation Control
Condensation and damp are often blamed on the building fabric, but poor ventilation is frequently the actual cause, particularly in bathrooms and kitchens where moisture is generated daily..

Where moisture comes from
Cooking, showering, drying clothes indoors and even breathing all add moisture to the air, which needs somewhere to go rather than settling on cold surfaces.
Why extractor fans matter
A correctly sized and ducted extractor fan removes moist air at the source, rather than letting it spread through the house and condense on colder walls and windows.
When it's a heating issue rather than a ventilation one
Cold surfaces caused by poor heating or insulation encourage condensation even with reasonable ventilation, so both need considering together.
Struggling with condensation?
Tell us which rooms are affected and whether extraction is already fitted, and we'll assess what's actually needed.
Questions we get asked
Is an extractor fan enough on its own?
It helps significantly, but persistent condensation despite good ventilation often points to a heating or insulation issue as well.
How do I know if my extractor fan is working properly?
A tissue held near the grille should be pulled towards it when running; weak or no pull suggests a duct or fan fault.
Can condensation cause structural damage?
Persistent condensation can lead to mould and, over time, damage to decoration and timber, so it's worth addressing rather than living with it.
