DAMP = PROBLEM = OPPORTUNITY
Damp is a common occurrence for lots of homeowners & landlords across the UK.
Damp can lead to & accelerate health issues such like asthma, but also damage elements of a building/property.
Most common types of damp are:
Rising Damp - occurs when groundwater is absorbed by materials which are porous, such for example brick, stone, or mortar. It then rises through the materials into the structure of the building. It’s a common type of damp, and typically affects the lower parts of walls and is symbolised by a tide mark, along with damp or wet patches showing.
Penetrating Damp – Very common type & usually caused by water seeping through external walls, around windows or doors and rooves. There is 2 types of penetrating damp, you have direct penetrating and lateral penetrating.
Condensation - the most common form of damp to be found. It’s caused by excess moisture in the air. It occurs when warmer & moist air comes into contact with colder surfaces, and when it does it condenses as water droplets. Over time if this isn’t managed it can evolve into mould growth & has the potential to cause structural damage.
Hygroscopic Damp - is when materials that are hygroscopic, absorb moisture from the present atmosphere. This type of damp can lead to mould growth & evolve into structural issues. Common hygroscopic materials are wood, brick & plaster.
Moisture from Construction – this can occur in either newly built or refurbished properties due to the construction materials used containing water such as plaster, concrete & paint. When these materials are drying out they release moisture into the atmosphere, which leads to increased humidity if not managed accordingly.
Common causes from daily activities are:
- Cooking
- Washing
- Bathing
- Inadequate heating & temperature fluctuations
- Inadequate ventilation during various activities
