Condensation caused damp It occurs when activities such as cooking raise the level of humidity in a building. This air condenses on cold surfaces, such as windows and walls. 'The more moisture there is in the air the more likely it is that you will get condensation', explains Chris Michael, Managing Director, Meaco.
If you've noticed mould and black patches forming around windows and walls in your home, there's a likely chance it could be condensation. Condensation occurs not only in high moisture areas such as the kitchen or bathroom, but often in cooler rooms on colder external facing walls and near windows.
This indicates that you may have what is known as rising damp. This is where water from the ground underneath or beside your house rises up through your brickwork through capillary action, creating damp in your walls which manifests as damp or wet patches or a whole damp section of wall just above your skirting board.
Left to its own devices, a condensation problem will often lead to mould growth in the home and can even penetrate walls and get into cavities, which can actually cause structural damage over time.
One of the most common signs of condensation is black mould which can occur on any walls of the property.
Accelerate drying by opening windows and doors. Use fans to move air around the damp walls. Dehumidifiers can help remove moisture from the air, which indirectly removes it from the walls, too. To speed up evaporation, remove molding and baseboards to prevent moisture from entering behind them.
Condensation is caused when warm air with vapour (damp) comes into contact with cold surfaces like a wall or a window. Condensation is possibly the most common form of dampness in buildings as a result of inadequate ventilation. If left untreated condensation damp can lead to mould and damage to your home.
The simplest way to get rid of condensation inside windows is to just open them, even a crack. Doing so reduces the room's humidity dramatically. 'The key to reducing occurrences of condensation is to improve ventilation by opening windows after showers and baths in the bathroom,' advises Jenny Turner.
Damp on walls can lead to wallpaper peeling, paint discolouration and plaster becoming crumbly. Look out for these signs, particularly when plaster is crumbling low down on walls, as this could be a sign of rising damp.
Sweating walls inside a home aren't harmless or natural. This phenomenon occurs when water beads on the surface of a wall or trickles out of the wall itself, often leading to damp patches and, if left alone, possibly extensive water damage.
To identify water leakage in your walls, look for signs like musty odors, mold growth, new or worsening stains, peeling or bubbling paint or wallpaper, buckling ceilings and floors, wet or discolored areas, the sound of dripping water or warped sheetrock.
Condensation
This may appear to be rising damp and can easily be confused. Condensation problems within a building are usually indicative of humidity and ventilation problems within a property. It is often believed to be caused by building defect, but that is usually not the case.
Local Damp Surveyors

In small amounts, condensation is nothing to worry about. However, if left to build up for long periods of time, it can lead to black mould. For those with certain pre-existing conditions, such as asthma, black mould can be very dangerous. In large quantities, mould spores can cause health problems for anyone.
Water Damage
A big question homeowners often ask is “does wet drywall always need to be replaced?” and the answer is almost always yes. Water stains, discoloration, bubbling, peeling paint,. and softened areas are all signs of water damage and are not nice to look at.
Dehumidifiers work by removing moisture from the air. This can help to reduce condensation on walls and prevent mould and mildew growth. However, dehumidifiers will not necessarily dry out damp walls. If your walls are damp, you may need to use a combination of a dehumidifier and a fan to help dry them out.
Depending on the severity of water ingress, it can take anywhere from a few days to a few weeks to dry a wet property out.
One of the best telltale signs of whether you're seeing a leak or condensation is the location of the water. If it's beading on or fogging up the glass, that's almost certainly condensation unless it's coming in from the top. If it's not on the glass but on the seal or the frame, your window is likely leaking.
Condensation is the most common type of damp. It's caused by a combination of excess moisture in the air and poor ventilation.
Most homeowners know a burst pipe by a rush of water leaking from a wall or ceiling, but it's not always that dramatic. Either way, it's still a plumbing emergency.
Look for Discoloration
If you notice any discoloration on your walls, it indicates that some pipe might be leaking and water is seeping through. At first, it might look like the walls are sweating, with beads of moisture. Later on, it will turn into a full-fledged wet spot.
Mould or mildew around windows and doors, a musty smell, and discoloured patches on wallpaper and walls are just some of the tell-tale signs of damp in your home.
Damp, discoloured patches on internal decorations and walls or discoloured tidemarks in line with external ground level or external envelope defects. Rotting floor timbers or skirting boards. If these show signs of wet or dry rot decay, penetrating damp is a very real possibility.
