Condensation is water vapour suspended in air. Condensation is a relatively new phenomenon resulting mainly from changes in lifestyle and our desire to keep heating costs as low as possible. Condensation is the air’s natural Moisture content settling on cool surfaces. The amount of moisture in the air is called relative humidity. If the humidity level rises about 70%, mould and mildew will be encouraged to grow. Astonishingly, the average family creates up to 10 litres of moisture every day, simply by washing, cooking and breathing. This moisture must go somewhere and be dealt with to avoid condensation.
Mould contamination is extensive, it can cause very high and persistent airborne spore and mould fragment exposures. Persons exposed in this way can become sensitized and develop allergies to the mould or other serious health problems.
Mould can damage your building in severe cases as well as your furnishings, such as carpets,sofers and cabinets. Clothes and shoes in damp closets can become soiled. In time, unchecked mould growth can cause serious damage to the structural elements in your home.
Moulds produce health effects through inflammation, allergy, toxicity or, rarely – infection. Allergic reactions (often referred to as hay fever) are most common following mould exposure.
Typical symptoms that mould-exposed persons report (alone or in combination) include:
These more serious symptoms are now widely reported as associated with mould cases and are mostly linked to mycotoxin exposure.
Rising Dampness is a blight that can affect external and internal walls alike. The source of dampness in this case comes is from ground water. The bricks and mortar in the dry upper parts of the wall acts like a sponge and draws water upwards. Well maintained, well-constructed walls will have an efficient physical damp proof course (DPC) and are unlikely to possess dampness unless the damp proof course has in some way been compromised, for example:
A Compromised physical DPC due to age and/or original use of poor material.
External materials ie soil, shingle, rubbish against the external wall below and above the DPC.
Existing DPC breached by home improvements ie addition of a porch, conservatory, adjoining wall etc. Materials within the cavity of a cavity wall construction.
Once the damp proof course has been compromised remedial action is required as soon as possible, continued presence of dampness on the upper walls will lead to deterioration of brickwork and internal plaster, décor.
