Why Do You Need A Damp Proof Course
Given the amount of rainwater we are subjected to in the UK, it is no surprise that many of us will encounter damp problems in our property at some point. This excessive moisture in the air and ground contributes to damp problems related to rising damp, penetrating damp and condensation.

Do you have damp patches on your internal walls?
The images below show the different effects damp can have on the walls of a property. Although damp patches on internal walls are a common symptom of most forms of damp, other signs such as internal salt marks appearing on brickwork or plaster can be an indicator that rising damp is likely the cause of your worries.
What causes damp patches on walls
If you have noticed damp patches, peeling decorations or black spot mould appearing on your walls, then generally speaking the most likely culprit will be one of the three types of damp outlined below. Identifying the cause of your damp walls is, of course, integral to pinpoint the correct form of treatment you will require to resolve the problem, so continue reading to see if you can establish the cause of your damp walls.
Damp walls caused by rising damp
Rising damp can only ever affect walls the property’s ground floor. The biggest tell-tale sign of rising damp is “tide mark” on the wall above the skirting. Another common symptom of rising damp is white marks left by salts that are drawn out of the brickwork. The salts and tide mark will often cause damage to paint or the peeling of wallpaper along with a damp musty odour.
Damp walls caused by penetrating damp
Penetrating damp refers to moisture ingress through a lateral wall. It is a damp problem that can penetrate walls at any level of a property. If water management systems like guttering or downpipes on the outside of your property look damaged or blocked then they are likely the source of a penetrating damp problem. Defective pointing and leaks in plumbing can cause penetrating damp.
On your internal walls, penetrating damp will create damp patches that damage plaster, leave watermarks and leave a damp musty smell.
Damp walls caused by condensation
Damp on walls caused by condensation will typically manifest as black mould spots on paintwork and wallpaper. Condensation problems are more likely to occur on cold, outside-facing walls but can affect any wall in the property given the right circumstances. Condensation problems are more common in the autumn and winter months when people close their windows and increase the humidity and is particularly prevalent in bathrooms and kitchens.
