How to Spot Damp

Unfortunately damp problems often fly under the radar for a long time before they are addressed, this can be because they are hard to spot or don’t pose an immediate problem to those living there.

Whether you are a property owner or looking to rent a house, it is worth knowing the tell-tale signs of a home with a damp problem to help you understand more about the problems and issues that it can create.

Spotting damp before it becomes a bigger problem requires you to take a closer look at your property. On the surface things may seem fine, however upon closer inspection you may find that you have one of the following:


Penetrating Damp

Penetrating damp is one of the trickier damp problems to fix. It is often caused by problematic external defects such as leaky gutters or bad brick work which may be causing any rain water to seep in to the walls of the house.


FEMA Warns Against Mold Issues

Rising Damp

Rising damp is caused by water and moisture being drawn up through the brickwork of a house. It can be a problem with an existing DPC or simply that your house is old and was never built with one to start with.


Condensation control

Excessive Condensation

One of the easier problems to spot as you will be able to see it on your windows. One issue posed by condensation is the mould that it leaves behind.You can prevent this from coming back by applying some mould removing solution to the affected areas.


There are some tell-tale signs which you should keep an eye out for when looking for any type of damp problem in a property – these are listed below:

  • – A musty smell
  • – Excessive levels of condensation on the windows
  • – Chilly or damp feeling in the air
  • – Changes in the plaster on a wall up to 1 metre above floor height
  • – Discolouration of the walls and ceilings
  • – Wallpaper peeling away from the walls
  • – Mould or algae on external walls


Spotting any of the above may be alarming but is often not as bad as you first think. However, regardless of how bad a damp problem may be, it should not be left untreated as it can be extremely bad for your health and home alike. It’s also possible that it will lead to further structural complications along the line and can affect people with respiratory problems such as asthma.

Damp is usually caused by poor maintenance of the home and will be flagged up if you are trying to sell or rent a house out.

All damp is treatable and should be checked regularly to make sure that your damp-proofing treatments are working and that the cause has been properly identified.
