Indoor Air Quality Testing
Ambient air testing using spore traps and inner wall cavity sampling to detect hidden mold and assess air quality.
Indoor Air Quality (IAQ) Assessment
Poor indoor air quality affects your health, comfort, and property value. Tanjun’s IAQ assessment measures airborne mold spore concentrations throughout your home to determine whether your indoor environment is safe.
How IAQ Testing Works
Step 1: Baseline Outdoor Sample We collect an outdoor air sample to establish the natural mold spore baseline for your area. Southern California’s climate means certain mold species are always present in outdoor air — the question is whether your indoor levels exceed what’s normal.
Step 2: Indoor Air Samples Using calibrated air sampling pumps and spore trap cassettes, we collect air samples from areas of concern — bedrooms, living spaces, bathrooms, basements, and any rooms where occupants report symptoms.
Step 3: Wall Cavity Sampling For suspected hidden mold, we can sample the air inside wall cavities. Mold growing behind drywall releases spores into the wall cavity that may not yet be detectable in ambient room air. This is particularly important after water damage events.
Step 4: Lab Analysis All samples are analyzed by Eurofins Built Environment Testing (AIHA-accredited). Results include spore type identification, concentration levels, and indoor-to-outdoor comparison ratios.
When You Need IAQ Testing
- Musty or earthy odors without visible mold
- Unexplained allergy symptoms, respiratory issues, or headaches
- After water damage or flooding
- Before or after mold remediation
- Real estate transactions (pre-purchase due diligence)
- Post-renovation verification (construction can disturb hidden mold)
Pricing
IAQ testing starts at $440, which includes 2 air samples (1 indoor + 1 outdoor control) plus lab analysis. Additional indoor samples are $95 each.
Understanding Your Results
We don’t just hand you a lab report and walk away. Charles will walk you through every result, explain what the spore types and levels mean for your health, and provide clear recommendations — all in plain language, not technical jargon.

Frequently Asked Questions About Indoor Air Quality Testing
Common questions about our indoor air quality testing services.
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.
