What is rising damp?
Excess underground water and leakages from other sources can often expose brick and masonry to enough moisture that it wicks its way upwards. This reaction is known as a capillary reaction and is very much like how a cloth touching a pool of liquid will draw up the fluid, even if the cloth is entirely vertical.
Most modern properties built within the last century or so will have a layer built into the walls near the ground to stop this process in its tracks, which we call a damp-proof course (DPC).
Rising damp causes
The main property issues leading to rising damp are:
- DPC faulty, absent or deteriorated
- Improperly installed DPC
- Adjoining structure higher than DPC
- Water leakage from plumbing issues
- Poor drainage of local land
- Faulty guttering, fascias or downpipes
- Damaged or poorly fitting roofing
- Local flooding
What problems can untreated rising damp cause?
If your home is currently showing any signs of damp you will be well aware how unattractive it looks but it's not just an aesthetic issue. Persistent damp often gives rise to mould, affecting respiratory systems and contributing to conditions such as asthma.
If left untreated, damp can spread throughout your property, causing widespread structural and visual damage, not forgetting the negative effects on the value of your home.
