Dampness seeping through the walls is one of the last things any person wants to see in their home, be it your own house or a rented one, it never brings good news. It can make your home feel cold, unhealthy and extremely unwelcoming. It can also mean that the building has structural issues.

Dampness can cause severe damage to the house, like the peeling of paint, leakage, mold and fungus. Many times, these stains tend to stay even after the monsoon season has passed.

So, it’s essential that you deal with the problem effectively. Luckily, damp walls can be treated without calling the professionals, if, you catch it in its early stages. There are easy signs to catch them early and simple tricks to stop it from appearing.

There are many reasons as to why these damp stains appear on the walls, the most common one being a blocked pipe. Other common reasons could be the splashing of rain water, sloping roofs that may collect water, and moisture seeping in from the ground level of the house.


Hold your hand against the wall, does it feel very cold or damp? Look for signs of mould or fungal growth which will appear as black speckled marks or grey growths on painted walls, woodwork and wallpaper.

Flaking paint or curling wallpaper can also be a sign. Pay close attention to the ceilings as well. Is it discoloured or stained in areas? This can all indicate that you have dampness seeping in.

Check your roof regularly for damage regularly. If any gutters need fixing, you need to get them repaired immediately. Installing gutter guards are a good way to prevent this kind of damp.



Condensation occurs when warm and moist air touches a cold surface like a cold external wall or windowpane. Ensure your that your home is well insulated and has good air ventilation. Provide a route for moisture to escape from your home to help minimize condensation.

Ensure your electronics like the washing machine and dishwashers are plumbed well and well vented. Install and exhaust fan in bathrooms and kitchens and make certain that they are kept running for enough time to clear the moisture in the room. Open your windows whenever possible, especially during winters.


Over a period of time, the house can develop cracks. These cracks are a way for moisture to seep into your house. You can seal these cracks with putty and remove the loose paint peels or plaster.

Once this is done, repaint the walls to effectively prevent the dampness from reappearing. Many paints used to paint the exterior walls of houses can be permeable and allows water to drain into the interior walls of the house.

To avoid this from happening, the walls need to be painted with a waterproofing coat. This creates a barrier for the rain, water and harsh winds and prevents dampness on the walls in your home.



Waterproofing the roof is just as important as waterproofing the walls of your home. The terrace is exposed to harsh weather even worse that the walls.

Tendency of water accumulating is more on the flat surface which may result in damp patches on the interiors. Hence, your roof should also have a coating of waterproof sealant that prevents seepage of water.
