A Smarter Way to Detect Hidden Mold

At Chicago Mold Dog LLC, we believe finding hidden mold shouldn’t require unnecessary demolition or guesswork. That’s why we’ve combined the remarkable scent detection abilities of a highly trained mold detection dog with years of real-world remediation experience to provide homeowners, businesses, and real estate professionals with a faster, more targeted approach to mold detection.

Hidden mold can develop behind walls, beneath flooring, inside ceilings, attics, crawl spaces, and HVAC systems without any visible signs. Left undetected, it can lead to costly repairs, ongoing moisture issues, and uncertainty about the condition of your property. Our non-invasive K9 inspections are designed to locate potential mold sources quickly and accurately, helping you avoid unnecessary damage while focusing attention on the areas that matter most.

More Than A Mold Dog Inspection

Most mold detection dogs are handled by professional canine trainers or inspectors.

Wally's handler brings something different.
With over a decade of experience performing medically aligned remediation projects, he understands not only how to find mold but also how contamination affects indoor environments and what successful remediation requires.

That experience provides valuable context that many traditional inspections simply cannot offer.
When your health concerns are real, experience matters.
