GTA Mold Inspections: Professional Designated Survey Services in Toronto, Mississauga, Oakville, Burlington, Hamilton, and the rest of GTA

Prior to planned renovation, demolition, or construction of an establishment, a Designated Substance Survey (DSS) is required to be conducted in compliance with the Ontario Occupational Health and Safety Act (OHSA). The OHSA and the ministry of labour stipulates that the presence of certain substances which deemed to be potentially dangerous to the workers and general public, be identified first, to allow construction workers to take precautionary measures in minimizing their exposure to these substances. Briefly, the designated substances in Ontario are the following: acrylonitrile, arsenic, asbestos, benzene, coke oven emissions, ethylene oxide, isocyanates, lead, mercury, silica, and vinyl chloride. The DSS report includes a thorough assessment of the presence, locations, and concentration amount of these designated substances in a construction or demolition site. With the right information on hand about these substances, the contractors will be able to take all the necessary measures to ensure the utmost safety and protection of their workers on site and the general public as well. In addition, the DSS report aids contractors and property owners alike to prepare well and avoid any unnecessary liabilities and compensation which may be incurred from getting exposed to these harmful substances.

Given the utmost significance of having a DSS for any construction, renovation, or demolition project, it is also important to get only trained and certified site inspectors who can conduct the Designated Substance Survey in the most professional manner possible. In Toronto, Mississauga, Oakville, Burlington, Hamilton, and the rest of GTA, the GTA Mold Inspections has been at the forefront in conducting Designated Substance Surveys using sophisticated diagnostic equipment. Our certified building inspectors are all highly skilled and well-knowledgeable and thus, the observations and testing we do are guaranteed to be accurate and comprehensive. All the necessary information about the designated substances and their corresponding analysis in terms of their presence, location, and concentration amounts in the building site are included in the DSS report.

MOLD INSPECTION FAQS

Can I have a mold problem if my house is only two years old?

Actually, given the proper conditions, mold colonies can appear within twenty-four to forty-eight hours. There have also been incidents where wood building products were contaminated with mold prior to being fastened in place at the home construction site.

Why can’t I proceed directly to the remediation of the mold?

You can, but we recommend a mold inspection that includes moisture measurements of floors, walls, and ceilings. Any materials with a high moisture content can indicate hidden mold growth. Comparison of air and mold samples can also indicate hidden mold, as well as reveal what kind of mold you are dealing with. We will be happy to discuss different mold inspection options that best fit your needs and budget.

Should a mold inspection be included in the list of pre-purchase property inspections?

A mold inspection can provide invaluable information about any structural investment you are considering purchasing. Home inspectors sometimes report mold when it is visible, but they typically do not have the aid of specialized equipment that reveals hidden problems (please see the following answer). And, through air sampling, the Certified Mold Inspector can alert you if there is a mold-related indoor air quality problem.

What are some of the features of the mold inspection?

A Certified Mold Inspector will conduct an indoor environmental visual examination (survey) that is enhanced by state-of-the-art devices. Some of these devices measure structural moisture (moist conditions encourage mold growth), air particulates (high particulate counts can be identified with an air sampling device), and thermal variations (cool areas may have a high moisture content). The enhanced examination thus helps pinpoint otherwise invisible moisture intrusion areas where hidden mold may exist (example: inside walls). Mold testing is also offered by the Certified Mold Inspector and samples are collected by following scientific protocols (there is more on mold testing in the following answers). You also receive a written report with recommendations for your specific situation.

How can I benefit from mold testing?

Mold sampling (and testing) will supply answers to questions like: Are mold spore counts higher in my indoor air than naturally occurring mold spore counts outside? What kind of mold (genus) is growing in my home? Is the discoloration, found on the floor (or attic) joists, mold? Sample analyses can also assist your healthcare professional in identifying medical problems that could be related to mold. And, should legal action become necessary, “chain of custody” protected samples would be essential for providing evidence of mold contamination.

What standards exist for evaluating indoor airborne mold quantities?

Indoor mold spore counts should be similar to those of the outdoor air in your immediate vicinity. This axiom is supported by scientific principles and approved by recognized authorities of air quality. These authorities include, but are not limited to, the American Conference of Governmental Industrial Hygienists; the New York City Department of Health & Mental Hygiene, Environmental & Occupational Disease Epidemiology.

How do I know if the mold in my house is toxic to my family and my pets?

It is difficult to be absolutely certain. Most mold sampling analysis does not identify mycotoxins, but it does reveal the mold genus. Genus results are compared to the list of molds that have the potential to produce mycotoxins (a few are listed in the following answer).

What species of toxic molds are commonly found in buildings?

Cladosporium, Aspergillus, Penicillium, and Alternaria–all considered toxic.

Stachybotrys, Fusarium, and Trichoderma (also considered toxic), produce mycotoxins that are easily absorbed into skin, intestinal lining, airways, and lungs. Other toxic molds include Coccidioides, Blastomyces, Histoplasma, and Memnoniella.

How long will it take to receive testing results?

Collected samples will be promptly sent to an accredited microbiology laboratory for analysis. Normal turn around time for lab results is two to three days.
