1. Inspection

First, CIS will pinpoint the problem areas in your building. Where is the mould growth? A crawlspace, the attic, or hidden in a bathroom wall or basement? All of these are common locations for mould growth. Throughout the mould inspection sophisticated sensory equipment is used to locate probable areas of growth.


Second, CIS determines the cause of the mould growth. Mould requires water to grow, therefore we look for a source of excessive moisture. Common sources include:


​Plumbing leaks

High humidity

Roof leaks


Third, we outline our recommendations. We provide expert advice and consultation specifically tailored to your unique situation.


Water backups



2. Test

Mould, allergens, Volatile Organic Compounds, bacteria, and other potentially harmful airborne pollutants lurk in our indoor environments. Many of these cannot be detected by a visual inspection alone. Fortunately we have the technology to measure the type and quantity of common pollutants including:


Mould testing

Bacteria testing

Allergy screening

Temperature & humidity


Particle count testing

Carbon Monoxide & carbon dioxide


3. Cleaning it up

You’ve found the problem, now what? Remediation (cleanup and removal) of contaminated materials must be done right.


​Our consultants will develop a mould remediation plan specific for your needs, ensuring your problem is remedied quickly and effectively. All of our consultants are certified in mould remediation and receive extensive ongoing education and training.


​Anyone can try to remove mould, but it takes a mould remediation professional to do it right the first time. If mould remediation is done improperly, it can easily do more harm than good.


These measurements are then used to correctly map out your indoor environmental conditions. Once we finish formulating a reason to your indoor air quality concerns, it is time to test it.



​We sample for mould, bacteria, particle counts, and allergen screening. This allows us to determine specific types and levels of contaminants that  affecting your indoor environment.




Kill Mould

Canadian Environmental Services will hep you identify and eradicate mould within your facility quickly and effectively.

Molds release small “spores” into the air. So, when mold grows indoors, the number of mold spores and fragments is usually higher indoors than it is outdoors. These spores are small enough that people can actually inhale them deep into the lungs. Inhalation of spores poses risk of developing respiratory problems.
