Signs of rising damp

Rising damp is a common problem that home owners have to deal with, so it helps to recognise tell-tale signs so you can have a professional inspect and fix it before the problem gets much worse. Here are some signs that you may have a rising damp issue at your property:


Peeling wallpaper or paint

Excess moisture in the walls can affect your wall coverings and is a sign that you have a damp issue. Whilst it could be condensation or penetrating damp, there is also a chance it's rising damp so it's best to get a professional damp proofer to come take a look to diagnose. You may begin to see your wallpaper peeling away from the edges, close to the bottom of the wall. Or, if the walls are painted you may notice it is starting to peel in certain areas and is visibly damp.


Flaky plaster

Another common sign of rising damp is flaky or bubbling plaster. If you notice powdery deposits on your walls and the plaster is bubbling and flaking, it could be because of rising damp. Re-plastering walls is an expense many home owners would want to avoid, so if you do notice a problem it's best to contact a damp proofing expert as soon as possible so they can diagnose and treat the issue before it gets worse.


Tidemarks on walls

Tidemarks can start to appear both on internal and external walls, they are caused by salts and moisture rising up the wall from the ground. Brown or dark yellow stains on the walls are also something to watch out for if you cannot see tide marks. Rising damp would likely effect up to 1 metre from the bottom of the wall, if it's higher than this it could be a penetrating damp issue. In order to correctly diagnose the issue, it's best to contact a damp proofing professional who can confirm what the problem is and the best way to fix it.


Rotten skirting boards/flooring

If rising damp is left untreated for a long time, it can begin to rot skirting boards and flooring. If the timber is easily crumbling when touched or is starting to crack, this could signal a rot attack. Long term damp problems can also result in fungus growing from the timber. Leaving damp untreated can cause a lot of other problems in the home's structure, so it's always best to consult a damp specialist before it gets worse and more expensive to fix.


Black mould on walls

Black mould can form on walls when there is excess moisture in the air, and is often associated with condensation. However, if mould is present on the lower section of walls on the ground floor, it could be a rising or penetrating damp problem and would require a professional to investigate and correctly diagnose.
