How to Tell What Type of Damp is Affecting Your Home

There are many different types of damp that can affect your home; the 3 most common being condensation, rising and penetrating. If you haven’t dealt with these things before, you may find it difficult to diagnose the problem. However, it is extremely important that you consult a professional as soon as you spot damp, as each kind needs to be treated differently.

Here are some signs to look out for that will help you to diagnose damp.


Many homeowners or renters will have already experienced condensation at some point or other and if you haven’t, you probably will in the future. It is possibly one of the easiest kinds to spot as it has many tell-tale symptoms. The reason that it occurs is excess moisture in the air, perhaps due to poor ventilation or faulty heating systems. Things to look out for include water droplets landing on cold surfaces like windows and walls, damage to plastering and paint, as well as the formation of mould if it is left untreated.

Rising Damp

Rising damp is another common household problem and it is caused by water from the ground travelling up the wall. Most houses have damp proofing, be it a course or membrane, built into their homes which prevents this from happening. However, older buildings don’t always have them and if your house is built on uneven ground, the damp proofing might not be adequate. With rising damp, you may notice that salt residue, stains and tide marks on walls. Because the water is leaking through the floors, your skirting boards and carpet may also show signs of water damage.

Penetrating Damp

Compared to rising damp where the water travels vertically, penetrating damp moves horizontally through the walls. The structure of the building is normally the main cause of this problem which could be anything from leaking pipes to faulty roof tiles. You may notice damp patches on your ceilings that worsen when it rains, so this is definitely something to look out for. Repairs to the building will need to be made if you want to rid the building of penetrating damp, otherwise it will return in the future.
