Mold air quality testing
Spore trap sampling with matched outdoor control, so indoor counts are read against a real baseline rather than a generic threshold.

We test. We don't remediate.
Independent mold, asbestos, and lead assessment. No remediation arm, no referral fees, nothing to sell you after the results come back — which is exactly why our reports hold up.
Testing only.
That's the whole point.
Most companies that test for mold also sell the cleanup. When the same firm writes the finding and quotes the repair, the finding is worth less — to an adjuster, to opposing counsel, to a judge. We took the remediation revenue off the table so the data stands on its own. If contamination is found, you choose your own contractor. If nothing is found, we say so.
Services
What we sample, and how
Every service ends the same way: accredited laboratory analysis and a written report you can hand to a carrier, a tenant, or an attorney without translating it first.
Surface & swab sampling
Direct sampling of visible growth and suspect materials, identifying water damage indicator genera such as Stachybotrys and Chaetomium.
Tape lift · swab · bulkAsbestos inspection
AHERA-certified building inspection and bulk sampling before demolition or renovation, analyzed by polarized light microscopy.
PLM · point count · TEM on requestLead paint & dust
Paint chip, dust wipe, and soil sampling for pre-1978 properties, collected under CDPH Lead Sampling Technician protocol.
Chip · dust wipe · soilPost-remediation clearance
Independent verification that a completed remediation actually passes — visual assessment plus clearance sampling against the outdoor control.
IICRC S520 clearance criteriaMoisture & humidity assessment
Moisture mapping and infrared survey to locate the water source feeding the growth, because sampling without finding the source solves nothing.

Every report ends in one of three conditions
We classify results against the IICRC S520 standard rather than describing them in adjectives. Adjectives are arguable. A condition is a position you can defend.
Condition 1 Normal fungal ecology
Indoor spore levels and genera are consistent with the outdoor control. No amplification, no visible growth. This is what a passing clearance looks like.
Condition 2 Settled spores
Elevated settled spores or fragments without an active growth source — typically cross-contamination from an adjacent area. Cleaning is indicated; demolition usually is not.
Condition 3 Actual growth
Active fungal growth confirmed by sampling, visible colonization, or water damage indicator genera. Documented with the basis for the call stated in writing.

The deliverable
What arrives in your inbox
Reports are written for the person who will have to rely on them — an adjuster, a public adjuster, an attorney, or a judge.
Executive summary
The finding and its basis on the first page, before the methodology. Nobody should have to read to page nine to learn the answer.
Sampling log
Every sample identified by number and location, with the analytical method and the outdoor control it is measured against.
Field photographs
Captioned, one per page, tied to the sample locations they document.
Unedited lab pages
The complete laboratory report attached in full, not summarized. Order numbers included for independent verification.
Condition & recommendations
The S520 condition, the reasoning behind it, and a scope of what should happen next — written for a contractor to bid against.
Certifications
Inspector credentials reproduced in the appendix, so the report carries its own proof of standing.
Who we work for
Reports built for the people who challenge them
Attorneys
Habitability, construction defect, and personal injury matters. Documentation prepared with the expectation that it will be examined.
Insurance carriers
Independent scope verification and cause-of-loss support, from a firm with no stake in the repair estimate.
Public adjusters
Analytical backing for claims that need more than a moisture reading and a photograph.
Property managers
Tenant complaint response, turnover clearance, and pre-renovation asbestos and lead screening.
Homeowners
A straight answer about what is in your house, from someone who does not profit from the cleanup.
Contractors
Third-party clearance so completed work is signed off by an independent party rather than self-certified.
