DH Damp Proofing & Plastering On The Signs Of Damp:


There are numerous things that count as signs of damp within your property. DH Damp Proofing & Plastering Ltd are experts at identifying causes and types of damp however that doesn’t mean that every property owner in London & Berkshire is too.


In this blog, we will look at the signs that indicate a damp problem.


Have you ever walked into a property or room and been hit by that musty stale smell? This is a big indication that damp is somewhere within the property. The smell is caused by mould that generates gases also referred to as volites. The mould and or mildew will be present on areas exposed to a damp problem however sometimes you may notice the smell before completing an investigation to identify the area affected.


Paint that is peeling is another sign that should be investigated for its cause. The paint peels because it is on a damp surface there could be rising or penetrative damp causing this or a leak behind the wall that you cannot see.


Tide marks on the wall that are in a capillary action up to height of 1.5 m or below is one of the tell-tale signs of damp namely rising damp and should you notice this in your property this should be taken seriously. You will need to identify the root cause and a treatment plan implemented by a professional.


Black mould is not only an unsightly consequence of damp but it can be very dangerous for anyone who has a pre-existing health condition especially one that involves the lungs. Black mould can be caused by both damp and condensation and they will both need a different approach to treatment.


Timber should be checked for signs of damp as timber that has bore-holes in it should be investigated further as this may be an indication of a timber infestation by woodworm or beetles. These both thrive in damp environment therefore you will need to be sure of the source of the damp and treat that along with any timber infestation.


Growths on timber that look like mushroom texture with a silvery skin on, red dust and crumbling timber or timber that is soft when you put a knife into it can all be signs of wet or dry rot which potentially can be extremely damaging to the timbers in your property. Please be aware that dry rot has the potential to quickly spread through the property as it can affect other materials and not just timber, this can lead to catastrophic damage and should be treated quickly and by a professional.


Discoloured or mouldy patches on walls can be an indication of penetrative damp and with this again you will need to identify the root cause of the problem as well as treating the aesthetics.


We would advise that if you suspect you have any form of damp problem that you gain advice from an experienced contractor and not attempt to treat any damp problem yourself as it may return and cause more damage.
