Our team

We’ve been through the wringer with mold, and we know how hard it can be to find answers. That’s why we started Fido Finds Mold.

The star of our team is our certified mold detection dog, Hee-do, trained by the renowned Bill Whistine.

We’re a small team, so we handle every inspection personally. We’re passionate about helping people find answers about their space.

Frequently asked questions

  • Mold dog detection is a non-invasive inspection method that uses a specially trained dog to locate hidden mold by scent. Mold gives off specific odors as it grows, and trained dogs are able to recognize these odors—even when mold is hidden behind walls, under floors, or inside ceilings.

  • Mold dogs like Hee-do can help pinpoint potential mold sources quickly, without opening up walls or drilling into surfaces. It’s why many people choose to hire a mold detection dog rather than taking more invasive approaches.

  • We work with people in all kinds of situations, including:

    • Homeowners dealing with moisture or past water damage

    • Renters trying to understand ongoing health concerns

    • Buyers and sellers during real estate transactions

    • Schools, offices, health care facilities, and other commercial spaces

    If you’re trying to figure out whether mold might be an issue—and where—a mold dog inspection can be a helpful place to start.

  • A well-trained mold dog like Hee-do can detect mold with impressive precision. His sense of smell is around 100,000 times more sensitive than a human’s, so he can detect even trace amounts of mold behind walls, under flooring, or inside HVAC systems.

  • We do not! Our inspections are non-invasive. Hee-do can identify mold hotspots without cutting into drywall or disturbing your space. He can also detect mold in ceilings, behind baseboards, and in other hard-to-reach areas.

  • No, we focus strictly on detection. That way, we stay unbiased and you can choose the right remediation team for your needs.

  • Not at all. Mold can affect air quality, building materials, and property value, whether or not you’re feeling symptoms. We work with renters, homeowners, real estate agents, and anyone looking for answers.

  • It depends. We offer a range of services, and pricing varies based on factors like the size of your space, where you’re located, and any unique property details. Reach out, and we’ll give you a clear, no-pressure quote based on your situation.
