Condensation Management Systems
Condensation Management Systems
Condensation management treats humid air on cold walls and windows in UK houses and flats, using extract and air change rather than a damp proof course. It is for winter mould in corners, on glass and behind furniture. A new injection does not stop this pattern. Request a quote with the form or WhatsApp.
Condensation is warm moist air meeting a cold surface. We look at ventilation, insulation and how the rooms are used.

Water on glass and black mould on silicone and cold corners
Mould behind wardrobes on outside walls
Worse from autumn to spring, and after showers or cooking
A house that was fine until vents were sealed or a new window went in
What's included
- Humidity and cold-surface checks
- Ventilation and extract assessment
- Mould-prone corners identified
- A control plan for air change
- Aftercare so the pattern does not return
What this visit does not do
- We do not fit a ventilation unit on a wall that is wet from rain or a leak
- We do not give medical advice about mould
- A dehumidifier is not a substitute for a missing bathroom extract
How the visit runs
We check humidity, cold surfaces, trickle vents and the extracts in kitchens and bathrooms, and how clothes are dried. If condensation is the diagnosis, the control plan is air change: working extracts, and a positive input unit only where the house can take one. Insulation and heating pattern are noted because a cold wall will still mark if the air stays wet.
Investigate first
We map the stain, take moisture readings, check salts where plaster has blown, and look outside at ground levels, gutters, pointing and the damp proof course line. The damp type is written down before any treatment.
Treat the path that is wet
Rising damp, rainwater, condensation, a bridged cavity or a wet cellar each get the repair that closes that path. A damp proof course is used only where groundwater is the cause.
Leave a record and a drying time
You get a treatment record and the guarantee that applies to the system installed. Plaster and paint wait until the readings say the wall is ready. Decorating a wet wall brings the mark back.
What changes the price
The figure depends on how many wet rooms need extract, whether a whole-house system is justified, and the condition of existing fans.
After the visit
Run the extract during and after baths and cooking. Dry clothes outside or in a vented room. Leave the ventilation unit running through winter and clean or replace its filter.
What fails if this is skipped
The mould stays away while the air change continues and the wall is not being wetted by rain. Anti-mould paint on an unventilated corner usually fails within a heating season.
Opening windows and wiping condensation helps day to day. It does not replace a bathroom that has no extract, and it does nothing for rain in the brick.
