Some of the causes of damp are obvious, but others are much less so. To that end, here are 5 of the most common causes of damp. After all, once you have managed to work out why your home is suffering from damp, it then becomes much easier to treat!
Even the tiniest of drips from an old or damaged plumbing system can lead to a much larger patch of damp. This is because the water droplets are all concentrated in one spot, meaning that the excess will soon begin to spread further across the surface. It’s not just old plumbing systems that can cause issues either, though. Sometimes new plumbing and pipes can drip, to begin with, so if you are planning to install a new system, it is well worth keeping an eye on the situation.
Leaky guttering can cause water to flow directly down exterior walls, leading to unsightly stains and patches of damp. Other types of gutters may feed water directly into your roof space, which can be particularly problematic. It is always a good idea to check your guttering is clear and remove any debris or obstructions to allow water to run freely.
Most buildings feature windows with outside sills that project out beyond the face of the wall. Buildings without these sills or with blocked or damaged sills can cause rainwater to collect below the window, leading to issues with damp.
Old-fashioned iron downpipes often rust through at the back, which goes unnoticed as it is out of sight. Certain types of downpipes are also prone to getting blocked with debris washed down from the guttering.
Cellars, basements and converted cellar rooms are prone to rising damp and high levels of moisture as they are located below ground level. Cellars with poor ventilation mean this moisture has no way to escape, quickly leading to complications.
