Moe was the mold inspection specialist who was assigned to our home. He was attentive in collecting a history of our property so as to be able to determine which areas to assess and which tests to administer. He visually inspected the attics and crawl space and continued to ask us questions regarding past remediation efforts, leak history etc. He was thorough in his approach and demonstrated true concern for our situation. We were surprised by the overall cost of the job and realize our ho...

The entire process working with Mold Inspection Sciences has been nothing short of amazing. Anyone dealing with health issues caused by mold can tell you what a nightmare it is, but MSI was incredibly helpful, thorough and professional from the very first phone call with the scheduler to the inspection itself. It's very apparent to me this company is run on ethics and empathy and I would choose them over and over again. MSI will be getting my referral to everyone I know. Thank you for a gr...

Alan exceeded my expectations during my mold inspection. I had some concerns about a recent bathroom remodel and living in an older home that has had several owners, I wanted some peace of mind because mold exposure can be so harmful to your health. Alan was thorough in his inspection and answered all of my questions. He was so patient when explaining the different types of mold and the varying levels of concern. He also gave me some good tips for preventing mold in my home. I appreciate t...

They were quick to reply back to my phone call and professional. I was able to get someone to come out on very short notice. I didn't have a big budget but I was still able to afford the services. The man who came out to do the inspection was very nice and understanding. I would recommended their services.

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.
