Mold Testing

Complete Air Quality Test For Mold

Indoor Air Quality Canada has been in the mold inspection industry for over 20 years.

We Focus On Inspection Services Only

At Indoor Air Quality Canada our commitment is to identify, quantify, and assess the level of fungal contamination in your home or office. IAQ Canada does not partake in mold removal services. We provide a comprehensive scope of work for mold removal following the CCA-82 guidelines. We highly recommend clearance testing after a third-party mold remediation company to ensure remediation due diligence and occupant safety.

There are many reasons why it is important to keep the mold inspection/testing company separate from the mold removal company.

Mold testing and inspection is a highly skilled job. We use state of the art tools and technology to accurately locate the mold within your building. If an area is missed during the remediation, there could be a very high chance of the mold returning. Successful mold remediation is dependent on two factors:

  1. Remove the moisture conditions that precipitated the mold growth.
  2. Remove the contamination (mold) caused by that moisture.

If these steps are overlooked, mold amplification will return.

Frequently Asked Questions

Building science failure is what causes mold in homes or buildings. Period. Building science failure is dampness, water leaks, high humidity, condensation, and poor ventilation. When elevated moisture and any type of organic material meet (e.g. damp cement floor and cardboard boxes), the potential for mold develops. It is this marriage between natural materials and dampness that begins the mold growth cycle to start in our homes or buildings.

Typically, building occupants smell something before they see any signs of visible staining. When mold begins to grow, it requires food and moisture. The food can be anything mother nature produces – paper, dust, wood, skin cells (organics). The moisture can be caused by high relative humidity, dampness, water leaks, condensation, or osmosis.

Frequently, occupants complain of musty, earthy, damp smells when descending the stairs into the basement.

  • Building science or building “skin / envelope” failure
  • Active water leaks from roof, window, doors, or flashing
  • Condensation inside wall cavities or around the wall and light switch outlets
  • Under basement floor vapor pressure and wall cracks
  • Poor site grading – water draining back toward the home
  • Over humidification
  • Poor ventilation
  • Storm water management – lack of eaves-trough


By simply identifying what combination of building failures is causing the problem, and providing tried and true remedies that solve the problem.

Homestars reviews

Would recommend. Easy to reach and communicated well. Prompt for our appointment. Really well informed and experienced staff. Our inspector was on time and honest with our options and possible solutions. Made us informed so we could move forward with putting into place a solution that worked for us.

Prompt, courteous and helpful. From the get-go, Shawn was interested in knowing the purpose of the visit in order to identify the root cause. He offered actionable tips to address air quality and moisture issues, and didn't recommend or upsell any additional services (e.g. in fact, clarified that there actually wasn't a need to get the asbestos and mould sampling I thought was required!). I would certainly turn to Indoor Air Quality Ottawa again if or when needed.

Shawn is extremely knowledgeable and helpful. I had contacted other companies in the past who were more focused on charging for unnecessary air samples and services. I highly recommend to contact IAQ if you have any concerns about your home air quality and want an honest expert opinion.

We are very happy to now know what things are affecting our allergies and asthma in our home as well as knowing the ways we can reduce the issues. We were also shown how to better heat (and cool) our home more evenly and found out that our furnace was on its last legs.

Shawn was extremely knowledgeable. Really really knows what he’s talking abt. Took lots of time with us to explain things. Took extra time to look at our air exchanger told us why it wasn’t working and made sure we understood how to work it. Had reliable contacts we could use to do repairs. I would very highly recommend this company.

Shawn was very helpful and professional in dealing with humidity and mold in our home. He takes the time to see and address the entire home system, rather than just put a bandaid on a single problem. We are very pleased at this logical and big picture approach, his expertise, and the solutions that he has recommended. It is not worth it to live in a home with air quality problems, whether it be mold, Carbon Monoxide, asbestos, or VOCs, and Shawn is your man to help address these problems!
