Frequently Asked Questions About Mold Detection Dogs and Hidden Mold Inspections

What is a K9 mold inspection?


Under the guidance of a trained handler, a mold detection dog uses scent to locate hidden mold inside the home. Unlike traditional inspections, a K9 mold inspection can identify mold growth behind walls, under floors, and in other concealed spaces.

 

How does a mold detection dog work?


Our dog, Roger, is trained and certified at the Florida Canine Academy by master trainer Bill Whitstine. Bill, a former FBI specialist in K9 drug detection and arson forensics, applies the same advanced scent detection methods used by federal agencies to train dogs for mold detection. This specialized training allows Roger to accurately identify hidden mold that may otherwise go undetected.

 

Is a K9 mold inspection more accurate than other methods?

 

Yes — a K9 mold inspection excels at locating hidden mold that cannot be seen during a standard visual inspection. Mold often hides inside wall cavities, behind cabinets, or under floors where moisture intrusion has occurred. Human inspectors typically collect samples from predictable areas — under sinks, near windows, behind toilets — but mold growth frequently follows unpredictable water pathways. A mold detection dog like Roger can pinpoint hidden mold sources with over 90% accuracy.

Do you perform lab tests and are they necessary?

 

Yes. As a certified microbial assessor, I work with several laboratories to provide a range of mold testing options. We can perform both air and surface tests to determine mold type, viability, and whether mycotoxins are present. Lab tests can also assess overall air quality, including VOCs, carbon ash, and non-fungal particulates. Whether lab testing is necessary depends on the specific situation and is discussed individually with each client. Lab results may also support medical care or guide the mold remediation process.

What kind of mold can your dog detect?

 

Roger can detect all molds, as they share a common olfactory signature. However, while the dog can indicate the presence of mold, he cannot identify the mold species or determine if it’s viable. Once mold is located, further investigation by a certified mold inspector or remediator may be recommended.

Can the dog find hidden mold behind walls or under floors?

 

Yes. The mold detection dog can identify mold hidden behind walls, inside cabinets, and beneath flooring. This ability makes K9 mold inspections highly effective for locating mold in places that are inaccessible or invisible to human inspectors.

 

What does the service cost?

 

The cost of a K9 mold inspection depends on the square footage of the home. Please contact The Mold Scout for a free quote. We also offer discounted rates for clients experiencing financial hardship.

 

Do you offer inspections for real estate transactions?

 

Yes. Many clients schedule mold inspections while in escrow to check for hidden mold or water damage before purchasing a property. The advantage of using a mold detection dog during real estate inspections is the immediate feedback: the dog can indicate mold presence on-site, while lab tests are less reliable and take longer to process.
