What actually is damp?
The musty smell and the damage that damp can cause is awful. Below you
will find a guide to preventing it in the first place and how to get
rid of it once it has arrived. If you are confused and

Damp means different things to different people
Damp can be a musty smell in the air, mould appearing on walls, a
tidemark on the wall, a cold feeling when you touch the walls, brown
patches on the floor, walls or ceiling or condensation. If your
problem is condensation then follow this
In essence there are three types of damp
1. Rising Damp
Brown tidemarks, cold feeling on the wall
The above will normally stop at about one metre from the ground and
only happen on walls that are in contact with the ground (this can be
internal walls as well as external). This is called Rising Damp
caused by the Damp Proof Course (DPC) either missing fully or
partially and the brickwork coming in to contact with the soil.
The brickwork sucks up the water and this causes the damp marks on the
wall. You will need to contact a surveyor to get the DPC fixed but the
resulting work will be expensive and will take time to plan and
execute. In the meantime a dehumidifier will dry the air in the room
which will mean that the wall will then realise the moisture that is
is holding into the room for the dehumidifier to suck in and process.
Although the wall will start to suck water up again from the ground
and the process will become cyclic, the dehumidifier will help to
control the problem until the DPC can be fixed.
If a brown patch appears in the middle of a wall or on an wall not in
contact with the ground.
This will be a leaking
pipe and will need immediate attention from a
plumber to find the source. If you do not cure this problem ASAP then
at worst a ceiling could collapse! In the meantime a dehumidifier will
help to dry out the effected area.
Anything else is caused by condensation and lots more information can
be found here.
Once you have identified and dealt with the causes of the
damp then the smell will go as well. It is vital to remove the
cause as soon as possible because the mould spores that come with damp
are damaging to your health.
Regardless of the cause of your damp problem it all comes back
to an excess of moisture and a dehumidifier can either solve the
issue completely or bring the moisture under control
have an opportunity to bring the structural problem under
control. Details of our domestic dehumidifiers for the
home can be found
