Dampness is also an indication of many things that are plaguing the construction of your house. Water damage can have a direct impact on the very foundation of the house.

While there might be many causes of dampness in walls, one must be prepared to avoid them while building the house. In this blog, we will discuss the causes of dampness in walls and how to spot them.  

What Causes Dampness In Walls

One of the major reasons for dampness in walls is due to a lot of moisture in the air and no way for it to escape. Such moisture can be caused due to a number of reasons such as drying the clothes inside of the house, stream generated from cooking, and perspiration while bathing. Also, any plumbing or building problems are causes of dampness in walls as they allow moisture directly inside the house.  

If your house has a poor ventilation system, dampness is one of the first major problems you might face. Also, if there is an issue of rising dampness in the basement of the house or the ground floor it can impact the upper floors too. And if you are living in a place with bad weather or moist weather conditions, you will experience dampness sooner than the places with a drier climate.

The dampness of the wall can lead to damp patches, the growth of black mold, and crumbling plaster. Such signs can cause a negative effect on the aesthetics of the house and are very unpleasant to look at. These can also spoil the paint and any paintings hung around the wall. If your house missing a roof tile or in case any of the roof tiles are broken, it leads to seepage of water directly into the house and can cause some serious dampness.  

Along with that, if your washing machine or dishwasher is leaky, its consistent use can also cause dampness. Blocked gutters and burst pipe overflows are the major culprits which can cause dampness around the house. Loosely sealed valleys and broken or faulty pipelines are also a reason why you might notice dampness in walls. Such dampness is often noticed first in walls adjacent to those areas where the usage of water is high, such as the kitchen and the bathroom.

How To Spot Dampness Of Walls 

One of the earliest signs pointing out the dampness of the wall is a kind of musty smell.

Carefully examine the walls, floor, and ceiling of the house in order to locate any such issues while they are still in the primary stage.

Salt deposits on walls can be another major indicator of dampness in walls. Dampness arises especially during the winter. However, if left untreated it can an issue all year round. The walls which are damp are colder to touch in comparison to other walls.

Water dampness in walls can cause runny nose, throat irritation, wheezing, coughing, eye and skin irritation and in some extreme cases can even trigger asthma. Along with that, one can also have severe allergic reactions when exposed to dampness frequently, and for a long amount of time.
