Air, surface, ERMI, mycotoxin, VOC and allergen sampling.
Free mold inspections for homeowners and property managers
There is no reason to pay someone to tell you that you have mold. We inspect for free across San Diego County, so your money goes into mold removal and remediation instead.
Mold testing in San Diego County starts at $195 for 2 samples (swab and/or air) with laboratory analysis and a report, $295 for 3 samples, and $75 per additional sample — some of the best prices in the county. The mold inspection itself, with pictures, a report and a free removal estimate, is free.

Tests we perform
Testing answers questions a visual inspection cannot: whether elevated spore levels exist in air you breathe, which genera are present, and whether indoor counts exceed the outdoor baseline taken the same day.
- Spore trap air sampling with an outdoor control sample for comparison
- Surface tape lift and swab sampling of suspect growth
- ERMI (EPA Environmental Relative Moldiness Index) dust analysis
- Mycotoxin screening
- VOC, allergen and bacteria testing where indoor air quality symptoms are the concern
- EMF and RF testing on request for whole-environment assessments
Independent laboratory results
Samples go to a third-party accredited lab, not an in-house bench. You receive the raw lab report alongside our interpretation, so a second opinion — from a physician, an attorney, or another consultant — is always possible.

Mold & Air Quality Testing FAQs
- Is a mold test necessary if I can already see mold?
- Not always. If growth is visible and the moisture source is obvious, the money is usually better spent on removal. Testing matters when mold is suspected but hidden, when health symptoms need documentation, or when you need clearance proof after remediation.
- How fast do lab results come back?
- Standard turnaround is two to five business days. Expedited turnaround is available when a real estate transaction or a health issue is on a deadline.
- Are DIY mold test kits reliable?
- Petri-dish store kits will grow mold from almost any indoor air sample, because normal air contains spores. They cannot tell you whether levels are elevated relative to outdoors, which is the measurement that matters.
