What is Damp?

Damp is a problem that often affects homes and businesses and is extremely common in the UK. It can cause mould, mildew and wood rot to form, not to mention the aesthetic damage it can cause to your interior decor. There are three main types of damp broadly speaking (though there is much debate re: how to classify damp - but that's a story for another time); condensation, penetrating damp, and rising damp. Each type of damp has its own unique set of symptoms, so it's important to know which type you're dealing with before you start any remediation process. To help you determine which type of damp you have, we've put together this brief guide. Keep reading to learn more about the different types of damp and how to identify them.


Condensation is the result of water vapor in the air condensing on surfaces. This can happen in a variety of situations, but the most common ones are when there is too much humidity in the air, or when surfaces are cold. Dampness can cause mould to grow, damage paint and wallpaper, and even cause electrical problems. To prevent dampness and other problems, make sure your home is well-ventilated and remember - it's a dehumidifier not a humidifier you need. Additionally, make sure you're home is well ventilated. This can be as simple as keeping windows and doors open when it's not raining, right through to extractor fans, Positive Input Ventilation units and the aforementioned dehumidifier.

Penetrating damp

If you're like most homeowners, you're probably familiar with the term 'damp.' However, do you know what it is and what it means? Damp is simply water that has seeped into the ground or walls of a building. It can come from a variety of sources - like faulty gutters, cracked bricks, orother structural damage or deficiency. If left untreated, damp can lead to serious problems like mould growth and structural damage. If you think you have damp in your home, it's important to get it checked out by a professional as soon as possible. They'll be able to determine the source of the moisture and take appropriate action to address the issue. In the meantime, make sure to keep an eye on the moisture levels in your home, and take appropriate action to prevent any damage from happening.

We do offer a Mould & Condensation Report as part of our mould remediation treatment which seeks to ascertain the cause(s) of the mould growth, identifying areas contributing to the problem, such as water ingress.

Rising Damp

Damp is a common problem that can affect buildings, causing mould, rot, and structural damage. This condition is most commonly found in older properties with solid walls, and is often caused by moisture rising from the ground. This can be addressed with structural repairs and/ or improvements based on a exhaustive inspection prior.

Check what kind of damp you have

It can be tricky to know what kind of damp you have. Luckily, there are three different types of damp that you can check for. Condensation, rising damp, and penetrating damp are all signs of moisture in the air. To determine the kind of damp you have, simply take the following steps:

1. Check the temperature. If it's cold outside and the room is damp, it's likely condensation damp.

2. Check the ventilation. If the room is damp but the windows are open, it's likely rising damp. The obvious sign is mould universally growing up walls from its base.

3. Check for moisture. If there is moisture on surfaces or if the floor feels wet, - particularly if cooking, showering, drying clothing etc is not regularly being carried out in the area - it's likely penetrating damp.

Early signs of damp

If you live in a humid climate, you're likely familiar with dampness. Dampness is a condition that occurs when there is too much moisture in the air. This moisture can cause mould and mildew to grow, which can be harmful to your health. Early signs of damp include musty odors, water stains, and peeling paint or wallpaper. If you notice any of these signs, it's important to take action right away. If moisture accumulates over time, the problem can become worse and even dangerous. In order to prevent dampness damaging your building materials and decorations - and worse, precipitating mould growth, it's important to take action as soon as you notice any of the early signs. We're always happy to provide free advice over the phone.


Damp is a common problem in homes, but it can be tricky to identify and fix. In this blog, we've gone over the three main types of damp - condensation, penetrating damp, and rising damp. We've also provided a checklist to help you determine which type of damp you have in your home. If you suspect that you have damp, be on the lookout for early signs such as mould, musty smells, and peeling paint. If you're unsure about how to fix the problem, it's always best to consult with a mould remediation professional such as ourselves.
