Mould Decontamination / Remediation
During the remediation process we will see that the dead mould fragments and spores are removed with a combination of brushing, sanding and vacuuming always with a machine equipped with a HEPA filter. We specify the use only of industrial-strength, HEPA-filtered vacuums to thoroughly clean all surfaces to avoid any spreading of the contamination, and then thoroughly clean and carefully decontaminate mould-infested surfaces, using environmentally-safe products. Although present industry standards do not require a biocide to be used in the surface remediation, we usually specify the use of an environmentally-friendly surface preparation product that also does destroy much of the microbial growth. We no longer routinely recommend use of bleach as a cleaning disinfecting agent because of its high toxicity and adverse impact on the environment. As a final treatment, to ensure that all residual contamination has been removed from every surface and corner of the work space and to ensure that the contamination won't return when environmental conditions favour microbial growth, we will apply a safe, long term antimicrobial product, called the Aegis antimicrobial as part of the Aegis Microbe Shield program. |

After
identifying the extent of the mould contamination, we will first
ensure that the appropriate decontamination specifications are
clearly explained to the client. If these specifications haven't
been developed for a project, then we can prepare for you the
specifications, based on current industry standards, which
include the New York City Department of Health mould remediation
guidelines, as well as CMHC, Health Canada, and EPA recommended
procedures. We will also review specifications developed by other
consultants, to ensure that they conform to industry norms. In
general, we will specify the isolation of the work area as
required by the specifications. The extent of the isolation will
depend on the surface area of the mould, whether a ventilation
system is involved and the sensitivity to dust/mould spores by
the occupants. If warranted, we will require the use of a
negatively-pressured enclosure.
