What condensation and mould ventilation fixes involves
If extract fans are weak, ducted into the loft or switched off, and windows stay shut in winter, that moisture settles on the coldest surfaces: window reveals, external corners, behind wardrobes and on bathroom ceilings. Mould needs that damp surface to grow. Ventilation is usually the biggest part of the cure, but not the only part.

Survey and findings

Questions about condensation and mould ventilation fixes in Derbyshire
Which towns in Derbyshire do you cover?
All of Derbyshire, including Ilkeston, Swadlincote, Staveley, Belper and Heanor. If your town is not listed, send the postcode and we will confirm.
Can you tell if it is rising damp?
We can tell you when the pattern does not look like condensation, such as a tide mark low on a wall or damp that appears after rain, and point you to the right specialist.
What is the main cause of condensation in a house?
The main cause is moisture from everyday living, such as showers, cooking and drying clothes, that is not being extracted, combined with cold surfaces where it condenses. Poor or failed extract fans are a very common cause.
Are prices different in Derbyshire?
Our guide prices are adjusted by region. In Derbyshire we use East Midlands rates, so new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £435 to £725 inc VAT per fan.
