What the work involves
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.
Mould treatment advice
How to clean and treat affected areas once the cause is fixed.
Survey and findings
Humidity and surface readings, existing fans flow-tested, and a written list of causes and fixes.
Fan upgrades
Weak or loft-vented fans replaced and ducted outside, with humidity control.

Questions about condensation and mould ventilation fixes in Kent
Which towns in Kent do you cover?
All of Kent, including Ashford, Canterbury, Maidstone, Gillingham and Chatham. If your town is not listed, send the postcode and we will confirm.
Is black mould dangerous?
Damp and mould can affect health, particularly for people with asthma, allergies, weak immune systems, children and older people, according to NHS and government guidance. It should be dealt with rather than lived with.
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.
Are prices different in Kent?
Our guide prices are adjusted by region. In Kent we use South East rates, so new ducted fan to outside through the loft or ceiling (insulated duct, roof or soffit outlet) is typically £490 to £825 inc VAT per fan.
Is the survey free in Kent?
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.
Send us photos of the mould and your fans and we will give a first view for your Kent home.
