What is Condensation?
-
Condensation usually occurs where moist warm air comes into contact with a colder surface.
-
Condensation is more noticeable where it forms on hard surfaces such as windows, window sills, mirrors or tiles.
-
Condensation can form on any surface, but it may not be noticed until mould growth is apparent or until some materials rot away.
-
The air can contain water vapour in various quantities and its capacity to do this depends on its temperature – the warmer the air the more moisture is held.
-
When this moist air comes into contact with either colder air or a colder surface, the air is unable to retain the same amount of moisture and the water is released to form condensation on the surfaces it comes into contact with.
Look for building defects first:
-
Missing or bridged Damp Proof Course (DPC)
-
Damaged gutters or down spout pipes
-
Porous pointing or brickwork
-
Leaking roofs
-
Inadequate ventilation
-
UPVC windows with no trickle vents
-
Leaking pipes either waste pipes, water pipes or radiators
-
Poor Ventilation
Cleaning Mould Spores from the air
Air Scrubbing
Mould Doctor will use a portable air filtration system to extract mould spores from the air in mould contaminated rooms as required to ensure the room treated has the best possible systems to prevent mould returning after mould eradication has been carried out.
The portable air filtration system draws in the air from the room and passes it through a Fine Dust Filter and then a Carbon Filter that will trap odours followed by a HEPA air filtration this system will efficiently remove air-borne mould spores from the air to help improve indoor air quality.
The air it filters is re-circulated to the surrounding area. This system is called an air scrubber and this helps improve the general air quality of the property.
Negative Air System
In extreme mould contamination Mould Doctor will use a negative air system to improve the extraction of mould spore filtration to clean the air.
A sealed containment area is created for the contaminated room, the HEPA air filtration machine is placed outside the containment, the air is then ducted out the sealed area with a precise airflow adjustment on blower motor with variable speed to maintain containment this creates negative air pressure (a slight vacuum effect) inside the containment area relative to surrounding areas.
This HEPA filtration efficiency of 99.97% is critical when using an air scrubber as a negative air machine, because the air scrubber and Carbon filter will only process the air one time, as it is ducted out this will then limit the spread of mould spores to other areas inside the property.
