Tim was great. The crew was so professional and easy to work with. They are an independent group that identifies issues without having an incentive to find things. They are far better than an all in one shop that will identify then fix.

Tim and mark did a great job and were very friendly and patient with us, our toddler, and our pets.

Michael J. San Diego, CA, 1/15/2025

I honestly can’t recommend Mold Inspection Sciences enough. As someone who is currently dealing with mold-related illness in the San Diego area, I called all of my options for inspection to hire an inspector who takes that into consideration. It’s overwhelming vetting your options for mold inspection so I’m hoping this review can help those who might find themselves in a similar situation. I called four companies who fit the criteria that I was looking for in terms of certification, testin...

Aram K. Santa Monica, CA, 12/21/2024

Christian was our inspector and he was punctual and polite. He was thorough with his inspection and answered all of my questions. The pricing was provided up front, so there were no surprises. We won’t have a full report for a few days, but, for a small fee, they are able to expedite results so we can receive a verbal report before Christmas. Overall, I’m satisfied with the service and am hopeful that the kind of mold that was discovered is not toxic.

Very easy to work with, very professional, and very thorough!!

Diane P. Laguna Woods, CA, 12/12/2024

Tim was very upfront on what to expect from inspection and how things might proceed based on his findings. He also took the time to show me the readings directly from his equipment so there was no mystery as to where precisely we had issues. He was on time and accurate in estimating how long the steps of the inspection would take. A+ would recommend to anyone!

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.
