Mycotoxin Testing & Targeted Mitigation in Ellicott City & Howard County, MD
Standard spore counts miss the chemical byproducts of toxic mold. We assay for trichothecenes, ochratoxins, and aflatoxins and neutralize the contaminated dust and assemblies they leave behind.

Signs your property requires this service
If you are seeing any of these warning signs in your Ellicott City or Howard County home, it is time for a technical inspection.
Symptoms despite “clean” counts
Ongoing illness after a normal spore report suggests mycotoxins that basic testing never measured.
History of Stachybotrys
Prior black-mold growth can leave persistent toxins even after the visible colony is gone.
Sensitized occupants
Households with chronically symptomatic or immune-sensitive members warrant toxin-level diagnostics.
Settled dust reservoirs
Toxins persist in dust long after growth stops, re-exposing occupants until neutralized.
Our step-by-step engineering standard
- Phase 1
Toxin diagnostic assay
We collect dust and surface samples and run deep mycotoxin diagnostics assaying for trichothecenes, ochratoxins, and aflatoxins.
- Phase 2
Source & reservoir mapping
We identify contaminated assemblies and dust reservoirs so mitigation targets the actual toxin load, not just visible growth.
- Phase 3
Targeted neutralization
Contaminated assemblies and dust are neutralized alongside S520 source removal to eliminate the chemical hazard.
- Phase 4
Verification sampling
Follow-up sampling confirms the toxin load has been reduced, closing the loop with lab evidence.

Why Howard County homes need this
Standard spore counts miss the hazardous chemical byproducts of toxic molds. Stachybotrys and Chaetomium — both common in chronically damp Howard County crawl spaces — release trichothecenes and ochratoxins that persist on surfaces and settle in dust long after visible growth is gone.
For sensitized households, addressing the toxin reservoir is what actually resolves symptoms, because the exposure continues through settled dust even after the colony itself is removed.
The Stack Effect
Up to 50% of the air on your main floors originates below grade. That is why a crawl space mold problem shows up as headaches, congestion, and musty HVAC return air two floors up — remediating the source is the only durable fix.

Frequently asked questions
How are mycotoxins different from mold spores?
Spores are the reproductive particles counted in standard tests. Mycotoxins are the toxic chemicals certain molds produce; they persist in dust and on surfaces even after the mold is gone and require a specific assay to detect.
Why did my regular mold test come back normal but I still feel sick?
Spore counts can normalize while mycotoxins remain in settled dust and porous materials. A targeted mycotoxin assay measures the chemical load that ordinary testing doesn’t capture.
Can you remove mycotoxins?
Yes. We neutralize contaminated assemblies and dust reservoirs alongside S520 source removal, then verify the reduction with follow-up sampling.
Is this necessary for every mold job?
No. It’s warranted when occupants remain symptomatic despite normal spore counts, when there’s a history of toxic mold, or when a household includes sensitized or immune-compromised members.
