How we do it
Ventilation is usually the biggest part of the cure, but not the only part. Heating patterns, insulation gaps and cold bridges matter too, and some damp is not condensation at all: leaks, penetrating damp and rising damp need different trades. We tell you if that is what we find rather than selling a fan that will not help.
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 Bristol
Are prices different in Bristol?
Our guide prices are adjusted by region. In Bristol 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.
Is PIV or MVHR better for condensation?
For most existing homes with general condensation, PIV plus good extract fans is the most cost-effective fix. MVHR suits airtight, well-insulated homes and full renovations.
How much does a condensation survey cost?
A ventilation survey with written findings costs £125 to £225 including VAT. If we are surveying for an installation we quote for, the survey is free.
Is the survey free in Bristol?
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 Bristol?
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.
If we fit the fix, the Bristol survey is free.
