Signs to help identify rising damp: damp proofing

Without using any equipment, you can use certain visual and touch signs to help identify rising damp. Typical signs that can identify rising damp include:

* Tide marks on the walls up to 1 metre caused by evaporation and salts from the ground.
* Damp patches and staining about 1 metre up a wall from the ground
* Wall paper coming off or peeling from the wall

Decayed skirting board

Other practical ways of to help identify rising damp include:

Running your hands around the suspected rising damp area. If you have wallpaper on your walls, you may hear a ‘crunching’ sound of the salts that have been drawn from the ground. If possible, look at the exposed surface of the brick or stone work. Check to see if there are salts forming, that the brick is actually wet (not just the wallpaper or paint). It is also important to note that rising damp only occurs on ground floor levels as it is moisture from the soil that is being drawn up the walls and thus causing the rising damp problem. If it is the case that your damp problem is on the first floor or above, it may be that you have a condensation problem or a penetrating damp issue.

Identifying rising damp – misdiagnosis:

It is not uncommon to hear rising damp being misdiagnosed for another damp related issue such as penetrating. Many individuals inexperienced with identifying rising damp issues may just assume that due to the usual sign of a tide mark on the wall, you have a rising damp issue. Before considering the wrong type of damp proofing treatment, consider the following:

* Do you have any faulty or leaking guttering that could lead to your damp issue? Is there vegetation growing out of the gutters?
* Do you have faulty of leaking plumbing?
* Have you had a damp proof course installed within the property over the last 20 years?
* Is it a possible condensation problem? If so check out our condensation web page
* Do you have cracks in the stonework or brick work?
* Do you have damp staining on stonework particularly adjacent to pipes?
* Do you have defecting pointing?

Any of the property problems above could suggest that the initial damp issue you have is not rising damp.
