Moisture condensation in buildings can support mould growth, particularly in bathrooms, bedrooms and, in some cases, wardrobes.  Many factors affect the location and severity of condensation.  Usually, condensation is related to normal occupation of the living space.  However, condensation may be an indicator of some other problem.

Many old brick buildings such as Victorian Terraces have solid brick external walls which depend on the cement rendering and paint coating for their waterproof integrity.  Water may also enter around windows and other wall penetrations.  There can be a variety of approaches to control of rainwater penetration through solid brick exterior walls.

There have been many cases of damp in buildings caused by leaking plumbing and mistaken for rainwater penetration and vice-versa.  Detail investigation is the key to identifying the source of the moisture.
Leaky pipes will cause dampness in walls, buildings and deterioration of the building fabric

When rain water enters the structure of a building there is a substantial risk of damage to the electrical system because water may pond on the ceiling and, frequently, the only drainage outlet is through the opening in the ceiling for the electric wires to the light fitting. There is also some risk of fire.

When Liquid Applied Waterproof membranes are not installed correctly, they may become porous and soak up water like a sponge. Water can be squeezed out of some sections. When rubbed, the membranes tend to delaminate, exposing free water resident within the membrane material and between the layers. Richard Cortis can assist in the specification of many types of liquid applied membranes to ensure proper function and durability.
