What is Indoor air quality ?

Indoor Air Quality (IAQ) is the name which refers to the air quality inside and outside our homes and buildings, importantly as it relates to the health and comfort of all of us. Air Quality can be affected by many pollutants like gases, carbon monoxide, radon, volatile organic compounds, particulates, microbial contaminants like mold or bacteria. it can also include mass or energy stressor that can induce adverse health conditions.

What can the indoor air quality testing detect?

Our Toronto indoor air quality testing services include the Analysis and Report of fungi (mold), bacteria (legionella, e. coli, salmonella, listeria…etc),  mycotoxins, endotoxins, allergens, pollen, radon and particulates in the air, swab, water, soil, asbestos, bulk, dust, wipe, food and consumer products.

The effect of Mold on Air Quality

Who needs IAQ testing in Toronto?

Indoor air quality testing is recommended if:

  1. If you need to comply with regulations or City ordinance.
  2. If you are suffering of health issues on a particular place only and not everywhere else.
  3. If you purchased a former grow op home.
  4. If you suspect of hidden mold, smell it but can’t see it.
  5. If your new home inspection found mold and you want check other areas.

How much does it cost for air quality testing in Toronto?

Testing for indoor air quality in Toronto pricing can vary depending on the testing requirements. a basic homeowners package will cost $400 and will include air testing of key concern areas including thermal imaging, voc readings and detailed report with solutions and direction to take if need be.

I smell a musty odour do I need an air test?

The best way to identify an odour is by testing the air, based on the results of the tested air we can determine the source and provide a solution.

How long does air quality testing take?

The average time when testing for mold is about an hour, however more complicated testing for other sources can be from a few hours to days.

I see mold do I need to test the air?

No, our guidelines indicate there is no need to test if mold is already visible. It is just going to confirm you what you already see. Removal is required regardless of the species and possibly under professional remediation if large areas are contaminated (more than 10 sq.feet) For peace of mind you might want to test after the mold removal is complete.

I found mold is it everywhere? is everything contaminated?

No, probably not unless all items were also wet or dusty. while spores can travel and spread they need a food source and enough moisture for several days. Of course is always good practice to wash clothes and any other items that were present in the area where mold was found. Mold spores will always travel to the food source and moisture area where they are decomposing. Mold can NOT decompose non organic materials but can survive on the dust present.

Does mold spread through my hvac?

Mold spores are very tiny and can spread easily to any air movement including wind, mold spores are everywhere in nature and exist inside and outside of all properties, they are part of nature. If you house or ducts  are dusty you will have more spores. If you live in a apartment or condo than you must check your fan coil unit for mold. Fan coil units can be a big source of mold and spores check our page on fan coil units.

Can the mold I am breathing make me sick?

Yes it can but it depends on you, your immune system, the type of mold and many other factors. While there are reported cases of serious complications there are no exposure limits; meaning we don’t know how much exposure is needed to make you sick since we are all different; what affects you might not affect someone else. Health Canada residential air quality guidelines for mold recommend to control humidity and diligently repair any water damage in residences to prevent mould growth; and to clean thoroughly any visible or concealed mould growing in residential buildings regardless of species. Please Note: in the absence of exposure limits air quality testing results from tests for the presence of fungi in air cannot be used to assess risks to the health of building occupants.

Mold symptoms or is just allergies?

Everyone immune system is different and reactions and responses can vary. If you are experiencing some form of allergy or reaction always go to your doctor first including a possible referral to an allergist. While we can provide you with air testing for all allergens, you should first know what you are allergic to. know the triggers here

Used in traditional Chinese medicine as an herbal supplement. It is also known as a “shelf fungus” because the fruiting body forms a stalk-less shelf on the sides of trees and logs. It is sometimes called “artists conk” because when you scratch the white pores of the fruiting body, the white rubs away and exposes the brown hyphae underneath. Thus, pictures can be produced on the fruiting body.
Potential or Opportunistic Pathogens: Unknown.
Potential Toxins Produced:
Suitable Substrates in the Indoor Environment: Unknown.

Stachybotrys and Memnoniella are closely related and many Memnoniella species have been renamed under Stachybotrys. Mycologists are continuing to debate whether Stachybotrys and Memnoniella should be grouped or split apart.
Stachybotrys may play a role in the development of sick building syndrome. The presence of this fungus can be significant due to its ability to produce mycotoxins. Exposure to the toxins can occur through inhalation, ingestion, or skin exposure.
Potential or Opportunistic Pathogens Unknown.
Potential Toxins Produced Mycotoxins produced by Stachybotrys include Roridin A, Roridin E, Roridin H, Roridin L-2, Satratoxin G, Satratoxin H, Isosatratoxin F, Verucarin A, Verucarin J, and Verrucariol.
Suitable Substrates in the Indoor Environment: Water damaged building materials such as: ceiling tiles, gypsum board, insulation backing, sheet rock, and wall paper. Paper. Textiles.
