    Damp is caused by the build-up of excess moisture within a building, from either internal moisture or intrusion from the outside. Damp proofing refers to several different methods used to keep excess moisture out of a building.

    Damp Proofing treatments help to prevent water being absorbed through walls or floors as well as entering exterior spaces of a property. If damp passes through the fabric of walls or floors, it could lead to structural damage as well as timber decay within a building.

    Damp can appear rapidly following heavy rain or slowly due to leaky guttering, damaged roof tiles or flashing. The only time you may become aware of a damp problem is when you find a damp patch on your wall, often in the plaster itself.

    Problems with damp in a building may be related to a variety of reasons. This may be due to poor build quality, lack of building maintenance or the deterioration of building fabric, with dampness often relating to one of three main issues.

    Rising Damp

    Rising damp occurs as water rises up mortar and masonry from the ground, or through solid floors if the damp proof membrane is damaged.

    Penetrating Damp

    Penetrating Damp can occur if water enters a property via damaged rainwater goods, leaking pipes, cracked render, or earth retaining walls from the outside of the building.


    Condensation is the consequence of high levels of humid air being trapped within a building. This causes damp patches on walls and water droplets on windows, which can lead to mould.

    Sometimes there are other causes of dampness in properties, such as leaking pipes or damaged drainage. These should not be overlooked.
