Meet Our Team


The Mold Guy has served the Los Angeles, Sacramento, San Diego, and San Francisco areas for 10 years. That's over 3,500 mold and indoor air quality inspections at homes, workplaces, and commercial buildings. We've handled small-scale residential inspections with minimal contamination issues, to large-scale commercial inspections with major contamination issues… and everything in between! There isn't a job too big or too small for our certified team of experts.

75% of our clients are people with sensitivity or health concerns. Typically when clients call us they have been experiencing health issues for a number of months. Health problems like this are the result of sick homes. A sick home is one with ongoing environmental issues like mold or bacteria contamination.
