Water-impacted building materials can begin to exhibit mould growth in as little as 48 hours. A water damage monitoring and management program will assist in rapidly addressing bulk water damage, including detailed procedures for drying, cleaning and remediating where necessary.

Health Canada’s Fungal contamination in public buildings: A guide to recognition and management, 1995 recommends “the development of programs to avoid the development of fungal amplification-sites.” Further, the American Industrial Hygiene Association’s 2013 “Position Statement on Mould and Dampness in the Built Environment,” recommends that a “formal mould/water prevention program with clear actions and responsibilities is required for an effective response to signs of moisture”.
