Mould Surveys

Mould Surveys
Moulds, fungi and yeasts are everywhere, airborne spores by the million. Even the most spotless house has some mould probably near the sink or bathroom. When room humidity rises due to excess moisture eventually it condenses on a cold surface. The condensation combined with an organic food source creates the perfect environment for mould.
Thermdry is experts in the surveying of moulds.  Our extensive background in floods, buildings and biological growths we can quickly and efficiently diagnose the cause. 
Thermdry offer surveys- leaking roofs, defective downpipes, gutters, condensation issues, penetrating moisture, rising damp, extractor fan problems. These can and do raise indoor humidity the precursor to mould. Lifestyle is also investigated as drying of clothes in a room can add to the overall humidity.
This service is for Norfolk although, with additional pricing, surveys can be further afield.
Questions I am frequently asked
1. Why when I spray with a proprietary anti mould/mildew product initially it disappears and within a few weeks, it comes back. The hyphae or roots grow into a food source up to 200 microns (1 micron is one-millionth of a metre) when you spray all you do is kill the surface growth leaving the roots intact to regrow.
2. When I paint with an anti-mould paint eventually it comes back. The active ingredients of the anti-mould paint slowly reduce in efficacy and eventually cease to be effective allowing the mould to regrow.
3. Is it bad for my health breathing in mould spores? We, humans, are designed to accept certain levels of mould inhalation, think of a walk in the forest millions of spores are free floating and we breathe this in. Healthy people can cope with this. In a contained area say a small room a mould colony can release millions of spores, a person with a low immune system can be affected, especially vulnerable are very young children and older people. The answer is to control the moisture control the mould.
Did you know that proprietary mould/mildew sprays are 1-2% Sodium Hypochlorite with fragrance buffering agents and 95% water? Mould is Hydrophobic (water hating) and when sprayed with water has an ejection mechanism to shoot its spores away allowing them to be airborne and easily inhaled and settle to start the next colony.
