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.

I had an outstanding experience working with Craig from Mold Detection. From the moment he arrived, he was professional, thorough, and incredibly knowledgeable. He took the time to explain every step of the process, making sure I understood what he was doing and why it mattered.

Craig didn’t miss a single inch of the house—he used detectors to methodically inspect each area and identified key spots that warranted further mold testing. His attention to detail and clear communication...

Sarah W. Wake Forest, NC, 7/25/2025

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!
