Frequently Asked Questions

A Tanjun mold inspection includes a thorough visual assessment of all accessible areas, professional moisture and humidity measurements, and thermal imaging to detect hidden water intrusion. We document findings room by room and provide a detailed written report. If sampling is needed, we collect air or surface samples and send them to our AIHA-accredited lab partner for analysis. The entire process typically takes 1-2.5 hours depending on the size of the property.

Home mold inspections start at $350 for homes up to 1,500 square feet. This includes moisture readings, humidity measurements, and a detailed findings report with remediation protocol if applicable. Air and surface lab samples are $95 per sample. Indoor Air Quality (IAQ) testing starts at $440 (includes 2 air samples). Post-remediation clearance testing starts at $550. We believe in transparent pricing with no hidden fees.

“Test-only” means Tanjun performs mold inspections and testing exclusively — we do not offer mold remediation (removal) services. This is important because companies that both test and remediate have a financial incentive to find problems. When the same company that diagnoses the problem also profits from fixing it, there’s an inherent conflict of interest. As a test-only company, our results are always unbiased. We have no remediation division, no referral kickbacks, and no reason to inflate findings.

Standard lab results from our AIHA-accredited partner (Eurofins Built Environment Testing) are typically available within 24-48 hours after sample delivery. Rush processing is available for time-sensitive situations such as real estate transactions or post-remediation clearance. Charles will walk you through every result and explain what the findings mean in plain language.

Tanjun Mold Inspections serves Granada Hills, Northridge, Porter Ranch, Chatsworth, North Hills, Reseda, Woodland Hills, and the broader San Fernando Valley. We also serve communities throughout Los Angeles County and Ventura County, including Simi Valley, Thousand Oaks, Calabasas, Sherman Oaks, Encino, and surrounding areas.
