You and Your Damp
by Chris Michael
What is your damp
Mould on the skirting boards, mould on the walls, a musty
smell, condensation on the window, dampness in a wardrobe or a
damp chill in the air?
Customers phone us every single day desperate for a solution and
not sure what to do.
With over twenty years worth of
experience we can certainly help.
In essence there are
3 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.
Older houses would not expect to have a damp proof course and
rising damp is likely.
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 release the moisture that it
is holding into the room for the
to suck in and process.
Although the wall will start to suck water up again from the ground
and the process will become cyclical, 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.
