We were more than impressed with Axxonlab. Charlie Leduc guided us to better understand the situation we were dealing with, and answered all of our questions. He is very knowledgeable and puts people before business: he explained how the test we were considering paying for will not give us the answers we were looking for. This I think is very rare in this day and age. We are really grateful for his guidance. 10 stars out of 5.

    Mold Testing & Inspection FAQ

    01. How much does mold testing cost in Ottawa?

    A typical residential mold inspection in Ottawa ranges averages at around $500 + tax, depending on the size of the property, how many samples are collected and the turnaround time requested for a report. While there are many inspection and mold testing options available from company to company, it is important to ensure you get a comprehensive service that aims to answer all of your concerns at the outset. We provide crystal-clear pricing information over the phone for our assessments before any work begins, and will gladly guide you through all options before you make a decision. Give us a call today at 1-888-675-5226 (LABO)

    02. How long does a mold inspection take?

    Most residential inspections take 1 to 2 hours on-site. You’ll receive your comprehensive report & microbiological data within 24 to 48 hours of the assessment.

    03. Do I need mold testing before buying a house?

    It’s a smart precaution, especially for older Ottawa homes or properties with a history of water damage. A pre-purchase mold inspection can reveal hidden issues that a standard home inspection might miss,  potentially saving you thousands in remediation costs. Most home inspectors adhere to their Standards of Practice, which limit their ability to conclusively identify mold in their reports. An independent mold testing professional is often recommended.

    04. What's the difference between mold testing and mold inspection?

    A mold inspection is a visual and environmental assessment of your property to identify conditions conducive to mold growth. Mold testing involves collecting air and surface samples that are analyzed in our laboratory to identify the types and concentrations of mold present. Axxonlab always combines both into our mold assessments to ensure clients get as much data as possible to make informed decisions.

    05. Is mold testing covered by home insurance?

    Testing itself is usually not covered, but if mold results from a covered moisture event (like a burst pipe), your insurance may cover remediation or repairs. We provide detailed documentation that supports insurance claims and our reports have been designed to be as robust as possible for these types of scenarios.

    06. Can I test for mold myself?

    DIY mold test kits are available, but they have significant limitations. They can’t identify the conditions that are conducive to its growth, don’t measure airborne spore concentrations accurately, and lack the professional interpretation needed to assess health risks. For peace of mind and actionable results, professional testing is recommended.

    07. What happens if mold is found?

    We provide a detailed report with the types and concentrations of mold detected, along with unbiased recommendations. Axxonlab does not perform remediation work. We’re focused entirely on accurate data, so you can trust our findings aren’t influenced by upselling. Fortunately, we have been in the industry for 15+ years and will help you navigate options based on the data from your assessment. We provide unlimited consultation following any of our assessments.

    08. Do you provide mold inspection and testing services for tenants?

    Yes, absolutely! Since we don’t provide remediation services and our comprehensive mold assessments are non-destructive in nature, we regularly dispatch our certified mold inspectors to rental units. We deliver unbiased reports and data-driven insights for all.
