Condensation and mould ventilation fixes in Gloucestershire

For Gloucestershire homes with streaming windows every morning, the fix is usually cheaper than people expect.

Our team is based in Great Barr, Birmingham, and we work throughout Gloucestershire, from Yate, Tewkesbury, Cirencester, Gloucester and Cheltenham. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

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.

Fan upgrades

Weak or loft-vented fans replaced and ducted outside, with humidity control.

Whole-home ventilation

PIV, continuous extract or MVHR where moisture is spread through the house.

Mould treatment advice

How to clean and treat affected areas once the cause is fixed.

Questions about condensation and mould ventilation fixes in Gloucestershire

Are prices different in Gloucestershire?

Our guide prices are adjusted by region. In Gloucestershire we use South West rates, so new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £465 to £775 inc VAT per fan.

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.

Is the survey free in Gloucestershire?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

Which rules apply to ventilation in Gloucestershire?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
