Condensation and Damp FAQ

Is it condensation or damp?

Condensation is water from the air settling on cold surfaces like windows and outside walls. It's the most common cause of mould in UK homes. Rising or penetrating damp comes from the building itself, usually from leaks or a failed damp-proof course, and needs a surveyor or builder. Our products are designed for condensation.

What humidity should my home be?

Between 40% and 60% is comfortable for most homes. Above about 70%, mould has the moisture it needs to grow.

How long do absorber refills last?

It depends on the room and the weather. In a damp bedroom in winter, expect a few weeks per refill. Drier rooms last longer.

Do I need an electric dehumidifier?

For most single rooms and small flats, absorbers plus daily airing and wiping the windows is enough. If your monitor still reads above 65%, add a mini dehumidifier.

I rent. Will this help?

Yes, nothing needs fitting. If mould keeps coming back even after you control condensation, tell your landlord in writing. Landlords must deal with serious damp and mould.
