Tanjun Mold Inspections is a fully insured small business that serves the Los Angeles and Ventura County areas.

We do not perform mold removal or remediations. Thus, as an independent third party test-only business — it allows us to focus on more objective mold assessments and unbiased recommendations.

The name Tanjun comes from the Japanese characters 単 (tan, meaning "single") and 純 (jun, meaning "pure"). Together, they convey the state of being — simple or pure — without any other elements mixed in or any complicated functions, structures, or forms.

Thus, “Tanjun” captures the overall value of the business, with the goal of ensuring each customer experience is as simple and uncomplicated as possible — and at the same time — providing the purest and most undiluted value of each product and service.

We deliver friendly explanations that non lab techs can understand, together with detailed reports of our findings and recommendations.

Before entering the Environmental Testing and Mold Inspection industry, Charles spent years in information technology — specializing in technical writing, data analysis, troubleshooting and root cause analysis, server and network engineering, and disaster recovery planning. That analytical background shapes how Tanjun approaches its work — methodical, thorough, and data-driven.
