Poor ventilationWhenever you wash, cook, dry laundry or even breathe inside your home, moisture is released into the air. If this has no way to escape, it can build up within your home and form condensation, which can lead to severe damp problems when left untreated.
How to spot damp caused by poor ventilationCondensation on the windows and other cold surfaces inside your home means you may have a problem with ventilation. Low ventilation may also be a problem if it feels cool or if there is dampness in your house or a certain room.
How to get rid of damp caused by poor ventilation• Reduce condensation.
• Repair and prevent any existing moisture damage.
• Keep your home ventilated by opening windows regularly.

There are different types of damp
Not all damp is the same. Different types will affect your home in varying ways. One type of damp will cause more damage (and cost more to fix) than another and vice versa. Usually, if you catch a damp problem early enough, you should be able to repair the damage quickly and keep the costs down .
• Condensation – generally caused by moist, warm air settling on cold walls and indoor surfaces, condensation is common in kitchens and bathrooms. You can spot it by the water droplets it causes on walls and other surfaces, dark mould forming around windows, and an unpleasant smell.
• Rising damp – most common in older homes that don’t have proper damp-proofing, rising damp usually starts in the foundations of a home and spreads upwards. It’s easily identifiable by cold, wet surfaces and mould growing in the external corners of your ground floor. You might also notice a strong, musty smell.
• Penetrating damp – leaking roofs, gutters or damaged mortar and rendering on external walls can often lead to penetrating damp. Early signs include the sudden appearance of a brown damp patch, most commonly around chimney breasts or in the upper corners and ceilings of a room.
• Black or dark mould – often referred to as mildew, black mould can be identified easily by its dark colour. It often appears in dark spots that spread and grow if you don’t tackle them .
When should you call a professional?
You should be able to remedy most minor damp issues yourself by simply improving the ventilation of your home or reducing the moisture in the air. But sometimes, the type or severity of damp in your home may call for professional treatment.
