Xander is thorough, professional and an asset to your company.
Karen G. North Hollywood, CA, 7/8/2026

Christian was on time. He acted professional and did a thorough inspection of the house. Definitely would recommend if you need these services. Took the time to explain and answer my questions.

Douglas T. La Canada Flintridge, CA, 6/23/2026

Zander did a thorough job with testing and explanation. The report they provided is helpful as well. A visit fee covers up to three different areas of the home, and accounts for the air within 6 or so feet around. Expect to have to pay for specific sample collections (yes, more than one) seperately from the visit price....it does get a bit more costly than I would like. But I trust their work.

Christian was very helpful on the initial phone call to set up our appointment. He was very informative on to what to expect and went into great detail on the options provided to us based on the size of our unit.

Tony A. Lake Forest, CA, 6/16/2026

We just had a mold inspection done at our house. Tim was very thorough and detail oriented. He was extremely experienced, he knew everything about mold and answered all my questions. He was also very helpful with his recommendations. We are very happy with his service!

Timothy was very knowledgeable and explained everything he was doing and gave us the best options to fit our budget. Would recommend.

Wyman W. San Diego, CA, 6/4/2026

Xander was thorough and meticulous going through every nook and cranny and walking me through the process. I appreciated his patience with me. Grace was also easy to talk with over the phone and helped me with what to expect during the inspection. I’m now looking forward to and anxious about getting the results back!

Tim was prompt, friendly, smart, efficient and thorough. He did an excellent job explaining to me and my contractor what we needed to know.
Stephen J. Laguna Beach, CA, 5/22/2026

We had the pleasure of having Tim out to perform a inspection on a condo unit we are renting. Tim is incredibly personable, professional and knowledgeable. You can tell he loves what he does! He showed great passion regarding the health issues surrounding mold toxicity. He explained the process to us and showed us exactly what he was working on. You can tell someone loves where they work based on how they show up and let me tell you, Tim personified this.

I would highly recommend Mol...

Tim was amazing! He was so kind and understanding and provided much empathy for my daughter's illness.
Bruce G. Lakeside, CA, 5/19/2026

Tim was exceptional.

Hunter S. Costa Mesa, CA, 5/13/2026

Xander did a great job inspecting the home I'm renting out. He was far more thorough than the inspectors that the landlord and property management company sent over. He did a great job helping me prove out that there are many widespread moisture issues throughout the home as opposed to just focusing on what is visible and what I pointed out.

Five stars for Xander and Mold Inspection Sciences. Very efficient, professional, and informative
Brett C. Venice, CA, 4/28/2026

Erwin was great. He really walked us through the process and identified potential areas for concern and where we shouldn't be as concerned. We tried 3 other service providers, and they tried to sell you everything. We could tell they were not sincere in their evaluation. Erwin was the exact opposite. Very experienced, thoughtful, and helpful. He helped us choose where we needed additional testing. I would absolutely use Mold Inspection Sciences again since they keep people like Erwin on st...

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.
