Our experience with Mo was nothing less than OUTSTANDING! He was friendly, professional, and very receptive to our concerns about potential mold in our Lacey rental. He took extra time to answer our questions and that means a lot! Would definitely recommend Mold SCI and, and more specifically, Mo to anyone looking for mold testing in their homes or rentals. Thanks again Mo, we appreciate you.

Jo D. Olympia, WA, 7/20/2026

Mo was very kind and understanding. He explained his process well and he didnt rush us when we asked questions. I am confident in his thoroughness and am requesting him back after remediation for a follow up.

We just had an inspection and Mo was terrific. He was extremely helpful, knowledgeable and thorough. It was evident that he really likes what he does and cares.

Rich C. Maple Valley, WA, 7/17/2026

Needed a mold inspection quickly this week in a rental unit. I was able to get Mo (tech) out on Wednesday afternoon. He provided information, walked through the process, and set expectations for wht he would do and what I should expect.

While I don't have the results back yet, the collection of the samples was relatively quick and straightforward.

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...

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.
