Everything one home needs to get on top of condensation this winter, in one box.
Condensation forms when warm, damp air meets cold glass and outside walls. Left alone, that water soaks into sills, seals and plaster, and gives mould somewhere to grow. The Damp Defence Kit tackles the moisture itself, not just the stain it leaves behind.
What's in the box
- Digital humidity monitor – shows the humidity and temperature in a room, so you know where the problem starts.
- 4 refillable moisture absorbers – draw water out of the air around the clock, with no electricity and no noise.
- Cordless window condensation vac – lifts the morning water off windows in seconds, before it runs onto sills.
- The beat-the-damp routine card – simple daily and weekly habits that stop condensation building back up.
Worth £86 bought separately.
How to use it
- Put the monitor in the room that feels dampest. Aim for 40–60% humidity.
- Place an absorber near each problem window or cold wall.
- Vac the windows each morning, and air the room for 10 minutes.
- Swap refills when the absorbers fill up.
Good to know
The kit is designed for condensation, the most common cause of mould in UK homes. Damp that comes from leaks or rising damp needs a builder or surveyor.

Questions
Condensation is water from the air settling on cold surfaces like windows and outside walls. Rising or penetrating damp comes from the building itself and needs a surveyor or builder. The kit is designed for condensation.
It depends on the room and the weather. In a damp bedroom in winter expect a few weeks per refill.
