You are investing time and money to create your dream home or any civil construction. But, unfortunately, one single sign of damp is ruining the whole appearance of the construction structure.

Not only the look but the forms are also getting much weaker due to dampness. In addition, the damp wall of the house is turning to be more fragile and easily breakable.

You may be thinking the repair cost of the damp wall is very high. But when you are going to find the damp in the primary level. Your fixing cost is getting much less. But how to find the primary signs of dampness in any civil constructions. Here is the answer for you.


4 Major Types Of Damp And How To Find Them

Damp is like small wood-eating insects. When you can find it from the primary stage of wood decay, then it’s repairable. But after extensive area decay. Therefore, it is almost impossible to fix.

Let’s know the primary signs of dampness and take precautions to save your constructions.

Here are four major types of damp.

1. Penetrating Damp

1. Penetrating Damp

Penetrating damp is simply moisture making its way into the home from the outside through a wall or, more often than not, a leaky roof. The main signs are damp patches, usually towards the top of the walls.

In more severe cases, you’ll also notice damage to wallpaper (it might be peeling) and flaking/bubbling plaster moving outside. Finally, there might be damage to walls or pebbledash. 

If the damp patches are in the attic, loose or damaged flashing on the roof is probably responsible. Missing roof tiles can also lead to penetrating damp. It’s always worth getting your roof checked by professionals like D&D Roofing and Sheet Metal, who will be able to stop leaks before they get out of hand.

2. Condensation


Condensation occurs when there is too much moisture in the air. This might arise from drying clothes inside, showering, and then letting the steam dissipate around the house or even an excess of humidity.

A musty smell is the most common sign, accompanied by telltale steaming across the windows and other cold surfaces like mirrors. 

Condensation isn’t as dangerous as penetrating damp, but it will lead to the growth of black mold if left untreated. It’s usually quite simple to find out what’s causing the condensation, and then various cleaners are available to tackle mold. Bathrooms are most commonly afflicted, and black mold tends to build up on windowsills.

3. Rising Damp

The bane of many a homeowner’s life, rising damp, has a fearsome reputation for its destructive bent. It’s hard to miss. Unlike penetrating damp, the signs will appear at the bottom of walls and in the lower parts of the house. Rising damp manifests itself as a yellow/brown stain that rises from the skirting board and spreads insidiously up the wall. 

Plaster and skirting boards will rot, the wallpaper will peel away, and in severe cases, even the floor coverings might start to lift. Rising damp is destructive and should never be left to spread unchecked. A full damp course (undertaken as soon as possible) is your best course of action when you notice any of these signs.

4. External Damp

Damp is most serious on internal walls, but that doesn’t mean that you should ignore signs on the outside of the property.

Wet patches on walls are dead giveaways of a problem, along with areas where vegetation has begun to sprout. Pipes and gutters are often the culprits, but leaving external damp unchecked will eventually cause interior problems. 

Penetrating damp begins outside, so it’s essential to check your property regularly. Roofs are a major area of concern too, but you can take some simple precautions to stop damp from developing.

Clear gutters regularly and scrub away any excess moss. Small patches of moss are natural and harmless, but a proliferation can harbor moisture.


When you are going to find the primary signs of damp, the fixing cost will be much less than your expectations. But dampness is a fast-spreading problem. After the minor signs slowly, it is going to eat your whole construction wall. So it is better to identify the problem and start to repair it on time.
