Craig was wonderful! He explained everything he was doing so we were educated and felt confident in getting all the info we need to present to our landlord. I now have peace of mind by getting our possible mold problem inspected so thoroughly!

David did an amazing job inspecting my home! From the moment he arrived and throughout the rest of the inspection, he was very professional, conscientious and respectful of my space while I was working from home. He was exceptionally knowledgeable and extremely detail oriented. He asked many questions and educated me during the process. His attention to detail, integrity and genuine concern for his clients set him apart from others. I highly recommend him to anyone who's looking for a trus...

Heidi M. Portland, OR, 7/29/2026

We live in rural coastal Oregon outside of the normal response zone. MIS was willing to send someone for a response fee. We couldn't find another mold inspection company that understood how important an inspection was for a CIRS patient that ALSO didn't do remediation. We wanted to make sure we weren't being upsold and had someone looking after our best interests.

Craig arrived and provided incredible education, asking personal health questions that are important for individuals with...

This was our second time working with Craig and Mold Inspection Sciences, and we couldn't be happier with their services.

My childhood home came up for sale unexpectedly, and my husband and I put in an offer, which was accepted. When I called to make a pre-purchase inspection appointment, Sarah D. was so kind and supportive of our situation, and worked some scheduling magic to help us find an opening within our inspection period (during the height of the busy season!)

The homeo...

Mold Inspection Sciences was great to work with. They were organized and efficient throughout. My favorite two things were working with Craig C. who was extremely knowledgeable, and that Mold Inspection Sciences does the testing but does not offer mold remediation. In other words, they will clearly identify the problems and they have no vested interest in upselling mold cleaning services because they don't offer them.

Adam B. Portland, OR, 7/2/2026

After long-term breathing issues due to allergies, we were concerned that their may be mold in the house. We highly recommend Mold Inspection Sciences, especially our inspector Craig. He took the time to gather information about our concerns and a thorough information about the house. Incredibly kind and knowledgeable, he answered all of our questions and walked us through the process of the inspection. We were happy to receive the great news that there's no mold, however, he did discover...

Craig was super helpful in talking through any concerns and questions I had regarding mold, the process of collecting samples and generally trying to diagnose what the issues could be in my home.

Hello, Although I did not meet Craig face-to-face, he called and coordinated the inspection services over the phone just as we had discussed. He also had thoughtful feedback, and although we don't have the final report yet, I am anticipating it will be thorough given Craig's recommendations. Thank you, Tommy Buchanan

Mold Inspection Sciences Client Review
Craig was absolutely exceptional. He came to the home that my family was renting to perform a scheduled inspection despite having completed a 9+ hour job earlier in the day. When he arrived, he was courteous, professional, and extremely knowledgeable. He spent nearly an hour patiently answering all the questions that my wife and I asked about mold growth and sample recommendations. I could tell that he genuinely cared about the health and safety of my family. Craig went above and beyond and I...

A 5-star rating!

J R. Wilsonville, OR, 5/22/2026

Had an super positive experience with Mold Inspection Sciences! Craig took the time to understand all of my concerns and was extremely patient with my many questions. I feel like I have a much better understanding of the mold risks in my home as well as the next steps I should take to clean up existing mold and reduce risk.

Kelsey W. Portland, OR, 5/22/2026

I cannot say enough good things about Mold Inspection Sciences, especially Sarah and Craig.

I contacted them because we were dealing with an urgent and very stressful concern in our home and needed professional environmental air quality and mold testing guidance quickly. From the very first call, Sarah was extraordinary. She called me back on a Saturday and spent nearly an hour listening, answering my questions, explaining the different inspection and testing options, and making sure...

W S. La Center, WA, 5/6/2026

Never something you want to need. But peace of mind if you do. We hired MIS to do a medical investigation of our home after a mold dog alerted us that we had hidden mold. MIS sent inspector Craig- who really went above and beyond with us. Super great guy, super understanding of medical sensitivity (especially since it was involving our child). He did all the sampling of the hidden areas that we wanted and we have peace of mind knowing just how thoroughly he inspected and tested our home, k...

Craig really went above and beyond with his inspection at our house. MIS is VERY lucky to have him! He is clearly so knowledgeable and so helpful, especially in a medically sensitive situation. Thanks for all the help Craig!
Angela F. Portland, OR, 4/22/2026

If you're looking for a mold inspector who is both highly knowledgeable and genuinely cares, Craig from Mold Sciences is the person to call! He is incredibly thorough and goes above and beyond to explain not just what he's doing, but why he's doing it. He answered every question in such wonderful detail. I was beyond impressed!

His attention to detail and commitment to transparency gave me a solid level of confidence. I feel very lucky to have found him and will absolutely use him ag...

Debbie B. Vancouver, WA, 4/21/2026

We had mold inside our car that was causing health issues. Craig came out to take the samples for analysis. He clearly has significant expertise in this area. He was thorough, and extremely knowledgeable. He arrived on time, was professional and friendly. He was able to answer all of my questions and took the time to make sure I understood how the process works.

Scheduling and communication with the company and with Craig was friendly, professional and timely. Thank you Mold Inspecti...

Cynthia A. Wilsonville, OR, 3/30/2026

Craig at Mold Inspection Sciences was so wonderful to work with! I was managing a complex remediation project at my mother's house while she was out of the country, and Craig did an amazing job of explaining the findings and helping me understand what was going on. He was incredibly informative and had a kind, calming presence during what was a stressful time for our family. I would definitely recommend Craig and MIS to anyone needing mold inspection services!

CB B. Keizer, OR, 3/10/2026

Craig was very helpful, professional and clean. The pre and post consultation went very well. Thoroughly happy with his service.

Dmitriy V. Portland, OR, 2/5/2026

Craig was extremely professional. He is clearly well trained in mold science and able to articulate in clear laymen’s terms that anyone can understand. Craig was very methodical in his inspection, explanations, and post inspection processes.

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.

Specialized Air Sampling Equipment
