Mo was very knowledgeable and thorough. He showed up on time and made the process and findings easy to understand. Great service.

Moe is very comfortable. Very thorough. And explained every action necessary.. he mentioned that he was not part of the Reclamation process if the samples came back positive for black mold. But being thorough we would get the best documentation possible.

Kody was terrific! He spotted a leak in my ceiling that I didn’t know I. had — it was very new - and probably saved me thousands of dollars as a result. I was able to get the leak fixed the next day. Kody was courteous and very knowledgeable.

Mo was an excellent inspector who took time to understand my situation, clearly explain his findings, never felt pushy for any additional testing beyond what I needed, and helped ease my concerns. He was also personable and a joy to work with in an otherwise unfortunate situation, I appreciated his empathy and experience.

Mold Investigation Methods

Moisture Detection

Moisture Detection

Mold growth requires three things: mold spores, a food source (building materials), and moisture or water. So, where we find moisture, we find mold. By locating the source of moisture and identifying hidden water intrusions, we can focus our mold investigation in the right areas.

If there was water damage from a flood, a leak, or a natural event we can inspect and assess the water damage along with identifying the presence of mold and make recommendations on the best way to return the home or office to a healthy state. 

Infrared Technology

Infrared Technology

We use FLIR infrared camera technology to enhance our inspection services. This advanced, non-invasive technology allows our inspectors to zero in and identify potential sources of moisture to more accurately determine testing and sampling areas. This will allow us to make even more precise conclusions and recommendations for action during the inspection.

Sampling and Testing

Sampling and Testing

We often get questions about how we determine which sample types to recommend, why we recommended a specific number of samples, and other questions about our sampling approach - known as our Sampling Strategy. Through the course of the assessment, our inspector will put together a Sampling Strategy specific to your property that will allow us to pinpoint problem areas, determine overall contamination levels, guide remediation efforts when needed, or in other cases rule out mold as a source of concern. If you have questions about the type of samples used or are wonder how and why specific recommendations are made, you can find tons of information in our Sampling Guides. Feel free to reach out to us with specific questions.

Certified Mold Inspectors

Certified Mold Inspectors

Performing professional, high-quality inspections requires three things—certification, education, and experience—values we do not take for granted. Each of our inspectors, consultants, and project managers is a Certified Mold Inspector (MICRO and MIS CMI). To protect your liability, property, and health, it’s important to engage the services of a professional and certified mold inspector. 

No Conflict of Interest

No Conflict of Interest

We don’t perform mold remediation, repair, or construction. We have no interest in the outcome of our inspections other than to ensure you have the information needed to return your home or office to a healthy state. Our expertise guides us, and we never have a conflict of interest regarding our findings and recommendations. We use a science-based approach and only do inspections and testing, never remediation.
