Mould Growth Mould Growth Introduction Mould growth is the result of temperatures and humidities being maintained at levels that suit fungal growth.
All moulds are natural and have a beneficial effect in breaking down organic materials.
Dry-rot, which is a particularly destructive form of fungal decay in timber structures, occurs naturally on tree stumps in the foothills of the Himalayas. Mould grows in buildings when we allow the conditions to occur either on internal surfaces, or within the construction itself. Moisture Generation Moisture is always necessary for mould growth. It occurs often through rising damp or through blocked downpipes and gutters. It also occurs through Condensation - both surface and interstitial.
