A mold inspector using state-of-the-art equipment will perform every test and inspection. Our clients receive the highest quality service.

We work with IMS Laboratory , a nationally-recognized and accredited lab dedicated to accurate data. IMS Laboratory’s analytical staff includes only Certified Indoor Air Quality Professionals, Ph.D. Microbiologists, Registered Mycologists (mycology is the study of molds), and Biochemists. IMS Laboratory is accredited through the American Industrial Hygiene Association (AIHA) and participates in Environmental Microbiology Proficiency Testing (EMPAT).

We are available to respond to mold problems nationwide.

We do not do mold remediation as this would be a conflict of interest.

Why use Mold Dogs™?

Properly trained dogs are exquisitely sensitive walking gas chromatographs. Mold Dogs™ locate mold substrates hidden behind partitions or on the insides of walls. Once the dogs identify a moldy area, the molds can be identified by visual inspection and culture of tape lifts. This provides a degree of certainty that you do not get from air sampler filters.

Top 7 Reasons to Use a Mold Dog™

1. Less Expensive. Mold Dogs™ generate quicker and more accurate results, which leads to lower remediation costs for homeowners and insurers. For schools, hotels, commercial and government buildings, cost savings can be quite substantial.


2. Cutting-Edge Technology. The "Nose" is cutting-edge technology and the latest trend in the home inspection industry. It's the only inspection tool that can detect and pinpoint sources of mold - critical information for lowering costs.


3. Proven and Trusted.
“Man’s best friend” has been used for years by military and law enforcement agencies to detect bombs and drugs, among other things. In Europe, dogs have been used to detect mold for over 20 years.


4. Dogs are Honest.
Dogs are trained to work for food and love...and NOT for profits.


5. Greater Peace of Mind. Research supports that if the dog finds mold, there's a high statistical probability you should investigate further. If the dog doesn't find mold, you can know with greater certainty that your home, office or school is safe from mold.


6. Hard Workers. In Germany, government authorities have found that a typical office building search of approximately 200 rooms can take one dog eight hours to complete.


7. Effective Problem Solvers. For REALTORS® concerned about escrow timelines, Mold Dogs™ can quickly and more accurately inspect a home, which gives both parties the feedback they need to quickly and effectively resolve issues.
