Tim was great! So helpful and nice.

Chad B. Laguna Beach, CA, 8/6/2025

As a contractor and architect specializing in the renovation and restoration of large period homes across Southern California, mold and moisture assessments are a routine and essential part of our early project stages. I've worked with many technicians over the years, and I consider myself fortunate to have crossed paths with Christian for a second time on one of our current sites. Christian is a standout professional....

Rob G. Beverly Hills, CA, 8/1/2025

Had a great experience from initial inspection, to the follow up report and next steps. Irwin was great in his inspection and helpful with making sure all of my concerns were addressed and we had very thorough discussions about the testing process. It didn’t feel like someone was trying to “sell me” on things, and the turnaround time for the report was quicker than I expected.

Deana G. Cypress, CA, 7/28/2025

The service we received was great! Christian not only went through our house extremely thoroughly, he was very patient and explained in detail their process and also educated us about mold. He also did not pressure us in any way to choose which tests to run once he evaluated our home. Highly recommend!

Elyssa K. Santa Monica, CA, 7/25/2025

We used Mold Inspection Sciences to do a thorough scan of our house for mold. I had a wonderful experience on the phone and was able to schedule a screening within a few days. Tim was amazing and was very detailed about his scans and information on our house. I am extremely pleased with our results and grateful to Tim for his follow ups and consistent feedback from start to finish. Highly suggest using this company!

Amanda Z. Lake Forrest, CA, 7/25/2025

Mold Inspection Sciences has been a great company to work with. We've used a couple of other mold testing companies but Mold Inspection Sciences has always been very responsive and able to schedule a tester/technician rather quickly. Irwin, our last testing technician, was very helpful and thorough with his report. Craig was very courteous on the phone. Highly recommend using this company in the LA area.

J. A. M. Arleta, CA, 7/25/2025

Irwin was really friendly and answered all the questions I had about mold signs and the inspection process. I look forward to having him do any future mold inspections that may be needed!

Tim was punctual, thorough, and very knowledgeable. I appreciated him taking time through the process to explain what he was looking for and how they use the tools. Highly recommend this company and Tim to anyone looking for Mold inspection services.

Joseph N. Laguna Hills, CA, 7/16/2025

Out of an abundance of caution, I hired Mold Inspections to conduct an indoor assessment of our house. I was lucky to learn that there is no mold but in the process, Christian offered helpful strategies to keep it that way. I would highly recommend this firm and the tech, Christian.

Lisa P. Los Angeles, CA, 7/11/2025

Tim did a great job performing a home inspection for me, inspecting for mold and taking both air quality and water quality test samples. After the inspection Tim talked me through his assessment and clearly communicated details regarding mold formation, remediation, and how test samples are collected. I appreciated his experienced perspective and he took the time to educate me a bit more on mold formation in different parts of the house and factors that can affect it. Thank you Tim.

Aric S. Laguna Niguel, CA, 7/11/2025

Tim is incredible!!! Very thorough, very knowledgeable and explains everything he’s doing. I wouldn’t wish mold issues on anyone, but if you’re dealing with that, I highly recommend having him come out!!

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
