Living in a damp house can be very dangerous and can cause you a lot serious health issues. As such, a little leak is something that should not be ignored.

The following are different ways to help you know whether your home is damp:


Condensation on a window is an indication of a damp house. Excessive condensation may be a sign of too much water vapour in the home and is an indication of a damp problem or poor ventilation. It is essential to ensure that you check your house regularly so to avoid exposing your family to the health problems that are associated with overly damp properties.

Black mould

Black moulds are another thing that you will notice in a damp house. Moulds are usually life threatening since the can cause severe diseases especially to those people with a lung condition. Make sure that you check the entire isolated ceiling, walls, door frame and window carefully to avoid causing more problems.

Tide marks and stains on the wall

Leaking pipes and overflowing gutter are usually the cause of damp patches on the wall. The wet patches can appear at any point or place on the wall. The tide marks are often caused by salts and evaporation from the ground. You will likely notice the tide up to 1 meter above the skirting board. If you fail to see the tide marks, then another very common sign is staining. Typically the stain is usually yellowish or brownish in colour and is also seen up to 1 meter above the skirting board. Stains make the wall to appear untidy and unattractive. Make sure to call a technician to come and examine your home so that to avoid getting more damage.

Salts within plaster

White fluffy deposits in the form of salt are a sign of a rising damp in your house. These salts can cause a lot of blistering patches on your walls. These white patches can destroy your wall leaving you with a financial burden.

Peeling of the wallpaper

If you notice that the wallpaper is coming off or is peeling from the wall, then that is an indication of damp. The wallpaper also starts becoming loose starting from the corner. Due to the moisture in the wall, the wallpaper becomes loose from the skirting board making the wallpaper turn or curve up.

Decayed skirting boards

When timber comes into contact with water, it is capable of decaying. The dampness causes the skirting boards to rot making them crack. Check out if the skirting board is easily crumbled, cracked or has localised fungus that is growing on. Ensure that you also check whether the boards have flaky or damaged paint.

Musty odor

Musty smells are often caused by damp conditions or mould spores. Any home that has dampness problem is typically affected by mould or mildew. A home develops a musty odour once it becomes damp. It is usually easier to notice the smell since it is very strong and uncomfortable. Musty odour can also cause health issues especially if the person is allergic to smell.
