After a odd incident of water damage occurs in a building, molds grow inside walls and then become dormant until a sequent incident of high-reaching humidity; this illustrates how mold can appear to be a sudden problem, long after a previous flood or water incident that did not produce a mold-related problem. Census-taking also show that mycotoxin levels are perceptibly higher in buildings that have once had a water incident (source CMHC).
Careful detailed visual inspection and recognition of moldy odors should be given over to find problems needing correction. Efforts should focus on areas where there are code of mellifluent moisture or inundate vapor (humidity) or where moisture problems are suspected. The investigation goals Mold Inspection should be to locate indoor mold growth to determine how to correct the moisture problem and remove contamination safely and effectively.
