What is a mold dog inspection?

A mold dog inspection is a fast and non-invasive method to locate hidden mold by scent. Specially trained dogs can detect microbial odors associated with mold growth and follow those scent patterns to their likely source.

Because a dog’s sense of smell is up to 100,000 times more sensitive than a human’s, specially trained dogs can trace odors that other inspection methods can miss.

Our certified mold detection dog, Hee-do, was trained by the top mold dog trainer in the country, Bill Whitstine, and has helped countless people find answers to their mold concerns.

Unlike other inspections and mold testing methods, a mold dog inspection focuses on pinpointing potential sources rather than measuring airborne particles alone. That means less trial and error, less unnecessary demolition, and clearer direction on what to do next.

Benefits of a mold dog inspection

Non-invasive

Inspections don’t require opening walls, drilling, or disturbing finishes, which can be costly.

Guides costly remediation decisions

Mold dogs can provide clarity on the scale of remediation needed and if the mold was successfully removed.

Instant results

Unlike lab-based testing methods, a mold dog inspection provides on-site findings the same day.

Catches issues before they become larger

A routine mold dog inspection can find small issues before they become costly remediation projects.

Helps narrow down problem areas

Locating potential problem areas helps you get to the root of the problem faster.

Covers spaces people and tools miss

Dogs can detect faint mold-related odors in hidden areas such as behind walls, beneath flooring, or inside ceilings and HVAC zones.

How the inspection works

1. Schedule your inspection

We start with a quick conversation about your property, concerns, and what you’re hoping to learn from the inspection. This helps us plan the visit and focus on what matters most to you.

2. On-site walkthrough

Just before our mold dog begins his search, we do a full indoor and outdoor visual inspection, evaluating areas with past leaks, humidity concerns, or building history that could contribute to mold growth.

This step helps us understand the environment so the canine inspection is as effective as possible.

3. Mold dog inspection

At this stage, our certified mold detection dog, Hee-do, and his handler, Simon, will search the space for mold-related odors. He works room by room, checking floors, walls, ceilings, and hidden areas where mold commonly develops.

The inspection is completely non-invasive—no drilling, wall openings, or disruption to your property. Anywhere our dog alerts, we place painter’s tape to indicate.

4. Next steps

Lastly, Simon will review findings—areas Hee-do flagged—with you, discuss possible reasons why, and offer practical next steps based on the inspection results.

FAQs

Do I need to prepare my home before the inspection?

1

No special preparation is required. We simply ask that floors and main walkways are reasonably accessible so Hee-do can move through the space comfortably. Normal household activity, furniture, and belongings do not interfere with the inspection.


Will the inspection damage walls or surfaces?

2

No. Mold dog inspections are completely non-invasive. We do not open walls, drill, or disturb finishes during the inspection.


What if the mold dog alerts to an area?

3

We’ll review the location with you during the inspection and explain what it may indicate. Depending on the situation, next steps might include targeted testing, monitoring conditions, or consulting an independent remediation professional.


How long does a mold dog inspection take?

4

Most inspections take 1–3 hours, depending on the size and layout of the property. Larger homes, multi-unit inspections, or commercial spaces may require additional time.
