Keep it dry. Keep it clean.

Keep it ventilated. Keep it healthy!

IAQ Ottawa has performed over 3000 indoor air quality inspections and improved air quality in some of Canada’s most harsh environments, including Canada’s Arctic. We have tested schools, daycares, hospitals, staff housing, dentist’s offices, multi-family complexes, airports, indoor garages, and office buildings in many Canadian communities. Our solutions and project management reflects on our style, building science knowledge and extensive experience.

An air quality inspection includes all components of your building:

biological, chemical, mechanical, building pressure, airflow ratio, and total dust counts

IAQ Ottawa’s inspectors and indoor environmental consultants are CMHC trained and certified. Every inspector is equipped to test for all hazards found in a building’s air quality. Our inspectors are also certified building ventilation designers. We can determine duct airflow and test building pressure differentials.

Benefits of an inspection

by a trained professional

Our professionally trained inspectors have over 13 years experience inspecting all aspects of commercial air quality. They will determine the cause of your mold or air quality problems.

Our certified inspector must first identify and address the building-related conditions that caused your air quality hazard prior to recommending a permanent solution. If not, the problem will simply return.

There is more to air quality

than testing for mold!

Are you introducing too many chemicals into the office?
Does your building contain hazardous building materials?
Does the ventilation perform optimally?

Our newer airtight buildings create problems for volatile organic compounds (VOCs) that off-gas chemicals into the building interior. Renovations can expose hazardous compounds like asbestos. Our certified inspectors are trained and equipped to measure all types of exposures, not just mold.

Do you require compressed air testing?


In the food manufacturing industry, compressed air quality is a critical factor. To ensure the protection of the food products processed in each facility, the compressed air must be contaminate-free. The Canadian Food Safety Enhancement Program has identified compressed air and gas used in the packaging and processing as a potential source of contamination. The potential hazard of compressed air quality is often overlooked during internal risk assessments, possibly due to the fact compressed air is odourless, tasteless, and colourless, or it may be that many people consider compressed air as just air.

Sources of compressed air contamination include the compressor itself and the ambient intake air. The contaminated compressed air can be a major issue for a food manufacturer. The outdoor air that is feeding the compressor may contain contaminates including oil vapour, micro-organisms, solid particles and water vapour. The placement and location of the compressor intake should be carefully considered to avoid as many contaminants as possible.

Moisture creates an ideal breeding ground for mold growth and the presence of moisture is the primary concern for the food industry. Fungi and microorganisms can grow inside the pipe system, then be blown into food containers or food products.
Pressure dew points must be below -26 ֯ C (-15 ֯ F) to inhibit the growth of fungi and microorganisms. The simplest way to eliminate moisture in a compressed air systems is to dry the compressed air to a specified pressure dew point. Other contaminants of compressed air include oil aerosols and vapours.

If you have an oil free compressor, it does not exempt the system of any compressed air treatment or testing requirements. Compressed air dryers and filters are always required.

Critical information to monitor air quality and assist in the prevention of contamination of the food supply can be provided with compressed air testing. To properly maintain service and testing of the compressed air system be sure to have qualified personnel employed.
Many sectors of the food industry use compressed air. An example of compressed air being used to clean containers before filling with food would be a bakery. The compressed air is also used to cut, sort and shape food products, depending on the application it can be used in a range of pressures from high to low.

International Standards Organization established a specification that targets compressed air which is ISO 8573. It is comprised of nine documents describing compressed air contaminants, purity classes, and the sampling and analytical techniques to be used. The compressed air system performance may be evaluated in terms of the compressor output at the compressor itself, at the various points of use, and in the piping downstream of the compressor. Compressor output knowledge is important in terms of selecting downstream filtration and assessing gross contamination of the piping system.

In systems where stead-state flow, pressure, and temperature cannot be maintained, partial flow sampling is inappropriate. At any point, full flow sampling may be used which requires a sampling device which has the capacity to handle the full flow at that point in the system. Most user request the full flow sampling as they want to know the air purity at the point of use where air may come in direct or indirect contact with the food/product. Compressed air supports the food industry as long as due diligence is taken to remove contaminants from the system, and regular compressed air testing is done.

Experience counts!

Trust an IAQ Ottawa professionally trained, veteran air quality inspector

IAQ Ottawa’s investigations begin with an occupant survey focusing on air quality related questions in your home or office.

Following the survey, our technicians will perform a visual assessment of the building and determine what sampling or investigative techniques are required to diagnose and identify your air quality problem.

Electro-chemical sensors, particle counters, or air collecting pumps will be calibrated and used to take samples.

We may sample for:

  1. Chemical and organic vapours (VOCs)
  2. Mold, lead, asbestos, oil spills, combustion gases
  3. Complete moisture mapping and thermal imaging
  4. Building pressure differentials and airflow analysis
  5. Gas and fuel oil leaks

The type of sampling we do will be determined during our investigation. You will receive an emailed, written report of the laboratory sampling results.

We only sell good advice

no duct cleaning, no mold removal, no mechanical equipment

just recommendations on how to fix and live in a healthy home or office

Our motivation is to improve your indoor air quality – period. We are not motivated to sell duct cleaning, mold remediation, or asbestos clean-up. It is not professional or industry good practice for an inspector to diagnose, clean, and clearance test their own work.

Once Indoor Air Quality Ottawa identifies the source of your air quality problems, our inspectors will recommend professionally certified and insured experts for all your remediation needs as well as independent, 3rd party clearance testing following all indoor environmental work.

Breathe easier

knowing your home air quality is healthy

Standard IAQ Inspection

An Air Quality consultant must have vast building construction and building science knowledge. The inspector must be certified with ventilation design (HRAI) Mechanical systems and building codes.

IAQ Ottawa has performed over 3000 inspections and over 20 years of building science experience since 2003 of experience testing, backed by the accreditation required to cover all types of indoor air quality issues… not just mold!

Air quality falls into two distinct categories; biological and chemical. An experienced consultant must recognized building conditions that generate bacteria, fungal or chemical off gassing.

An action plan must be directed at solving the building condition that precipitated the air quality concern first. Only then does the remediation plan address the contamination followed by 3rd party clearance testing to ensure a safe and healthy occupancy.

Are You Suffering From Allergies?

Why suffer alone? There is a solution!

Allergies are a hypersensitive immune system response to aerosolized particulate or substances such as pollen, dust, dander, mold, or dust mites. A typical seasonal allergy is triggered by exposure to an RSP (Respirable Suspended Particulate), or commonly referred to as airborne allergens.

Environmental Conditions

Environmental conditions vary with season, humidity, exposure time, and concentration. Outdoor allergens enter our living spaces, or become concentrated indoors through occupant activity or environmental conditions found in our home or office.

Airborne allergen reactions require the aerosolized trigger to be present in the occupied environment. Effective allergy treatment first response is to remove the affected person from the environment. This becomes difficult when the response is triggered in our own homes.


Airborne allergen reactions are caused by amplification of identified indoor particulate in the living space. These particles are typically very small and can be aerosolized by occupant activity, mechanical system, vibration, seasonal pollen and seeding, or dampness.

The good news is that most aerosolized allergens have mass, and are affected by gravity. If allergen size can be measured, it can be counted to establish exposure and cleaning effectiveness.

Ultrafine particle counting is a means of determining all sizes (up to .03 microns) of aerosolized particles in our homes. If we can measure it, we can remove it. Modern air quality laser particle counters or total dust monitoring devices can accurately determine what exposure level you inhabit.

Once particle size and quantity is established, effective air scrubbing, ventilation, or HEPA filtration strategies can be incorporated into your daily routine to reduce your allergen concentration and personal exposure. Don’t just treat the symptom, reduce the trigger!

Modern environmental cleaning methodologies can be used to greatly improve the air you breathe.

Is your home ready for your baby?

Health Canada identifies three groups that are most susceptible to indoor air quality contaminants – seniors, pregnant mothers, and newborns.

Our indoor environment may contain biological or chemical air quality concerns that have not yet been identified by the building occupant. Renovating for the new baby may aerosolize mold, asbestos, or lead particulates into the indoor environment. Construction dust, paint odours, glues, and compounds affect our air quality. Ultra-fine particulates accumulate in our homes overtime, typically aerosolized by common occupant activity.

Have your home inspected by a certified, experienced, air quality technician. A typical inspection will identify air quality concerns and will provide the homeowner with effective strategies for remediation, abatement, or cleaning.
