How an Ottawa Mold Inspection Works
Three steps, from your first call to a report you can act on.
Book a time that works
Use the form, book online, or call. We confirm an arrival window and ask a few questions up front so the inspector shows up knowing what to look for.
On-site assessment and sampling
An IICRC-certified inspector walks the property, takes moisture and humidity readings, checks the areas most likely to hide a problem, and takes swab or air samples only where they will actually answer your question.
Lab-analyzed written report
Samples go to a third-party CALA-accredited laboratory. You get a written report with photographs, the moisture source we identified, lab results, and a recommended scope of work, typically in 24 to 48 hours.
Mold Inspection & Testing Services in Ottawa
The first step in getting rid of a mold problem is identifying where it’s growing and what’s causing it. A professional mold inspection will answer both of these questions and help you plan for a safe remediation.
With Mold Busters’ mold inspection services in Ottawa, you get a comprehensive assessment of your property, which utilizes both qualitative and quantitative methods. We examine various indicators of mold contamination, including:
- Temperature & humidity
- Particle levels
- Potential moisture issues
- Structural defects
- Overall indoor air quality
Our high-quality, industry-standard equipment allows us to check hard-to-reach areas as well as spots that are prone to moisture and water intrusions.
The goal of our mold inspections is to gain as much information as possible about your property so that we can plan an effective mold remediation strategy.

Our Mold Testing Services in Ottawa
Mold testing is a quick tool that confirms or denies the presence of mold in your Ottawa home or office. It can be used to give you a qualitative yes-or-no result or to quantitatively measure the exact amount and type of mold spores in your environment.
For this reason, we offer two different kinds of testing for mold: swab tests and air sampling. The one you choose depends on your specific needs.
If you just need to know whether or not you have mold (and don’t care about the species), then the mold swab test can provide you with an answer in seconds. However, if you’re concerned about your indoor air quality and would like to know the exact concentration of different molds present indoors, opt for the mold air test.
Keep in mind that air samples need to be analyzed in a third-party microbiological laboratory, so results are not available instantly. Turnaround is typically a few business days, and we can expedite it when a real estate closing or an insurance deadline depends on the result.

What You Get With an Ottawa Mold Inspection
Every inspection ends with a written report, not a verbal summary at the door. You get photographs of what we found, where the moisture is coming from, and lab results if we took samples.
What the report covers:
- Photographs of each affected area, with location and approximate extent
- The moisture source we identified, since mold returns if that is not fixed
- Lab results from a third-party CALA-accredited laboratory, when samples were taken
- A recommended scope of work, or written confirmation that no remediation is needed

Many mold inspectors will diagnose a mold problem by a simple visual assessment. However, we know that not all mold is visible and, further still, not all discoloration is caused by mold. Before making any kind of diagnosis or recommendation, we thoroughly check your property and suggest mold testing if there is any doubt. No scare tactics. And we will NEVER pressure you into paying for a service you don’t need.
Not sure which test you need? Ask us first.
Tell us what you are seeing or smelling and an Ottawa inspector will tell you whether an inspection is enough, or whether sampling will actually answer your question. No obligation.
Swab Test or Air Sample: Which One Do You Actually Need?
Most people ask for “a mold test” without knowing there are two very different ones. Picking the wrong one is how you end up paying for a result that does not answer your question.
| Swab test | Air sample | |
|---|---|---|
| Answers | Is this specific patch mold? | What is in the air I am breathing, and how much? |
| Best when | You can see and reach the suspect area | You smell something but cannot find a source |
| Result speed | Seconds, on site | A few business days, after lab analysis |
| Tells you the species | Yes, with lab analysis | Yes, with spore concentrations |
If you can point at the spot, a swab usually settles it. If the problem is a musty smell with no visible source, or you want to know whether a finished basement is affecting the rest of the house, air sampling is the one that answers the question.
More samples is not automatically better. One well-placed sample taken where the moisture actually is will tell you more than five taken at random, which is why we walk the property and find the moisture source before deciding what to sample.
Documented clearance
When an inspection leads to remediation, the project ends with a documented clearance confirmation including photographs of the completed work. A formal clearance report is available on request. We will not tell you a property is permanently mold free, because mold comes back if the moisture source is still there. That is why the moisture source is in every report we write.
Up to 5-year transferable warranty
On qualifying projects where the full recommended scope is completed, we offer a conditional workmanship warranty of up to five years that transfers if you sell the home. It is not automatic on every job, and an inspector can decline it when the scope is cut back or the moisture source cannot be resolved. Ask about it when you review your report.
Mold Inspection and Mold Testing FAQs
Yes. Upon completion of every mold inspection, Mold Busters Ottawa sends you a final report by e-mail. The report includes the inspector’s observations of any problems identified during the inspection and a professional recommendation whether or not remedial action is necessary.
If you had any air quality tests taken during the inspection, the final report will also include a summary of the results and will be delivered by e-mail to you within 2 to 4 business days.
For more information about written reports or to find out how you can receive your air quality test results faster, contact us today.
An inspection comes first either way. Our inspector walks the property, checks moisture levels and looks at the areas most likely to hide a problem.
If what we find is visible and clearly mold, testing may add nothing you do not already know. Testing earns its place when there is doubt: a musty smell with no visible source, discoloration that may or may not be mold, or a situation where you need lab documentation for a landlord, a buyer or an insurer. We will tell you which applies before you pay for anything.
