Mold Inspection, Mold Testing & Specialty Testing in Duval County, Florida.
Founder-performed by Daniel Melendez, a microbiologist and former environmental lab analyst. Lab-supported, independent of remediation, with Duval County inspections scheduled by appointment from Orlando.
What is mold inspection in Duval County?
A mold inspection in Duval County is the structured assessment of a home or commercial property to identify mold growth, moisture sources, and indoor air quality conditions. The process combines a visual walk-through of every accessible space, moisture-meter readings on each suspect surface, thermal imaging that flags temperature anomalies worth investigating behind walls and ceilings, an evaluation of the air conditioning system, which is the most common hidden source of mold in Florida homes, and attic access where it is safe. Three accredited-laboratory samples are included and collected where the findings call for them rather than to a fixed formula. Everything is documented in a written report with photographs, instrument data, and laboratory results. Every inspection is performed personally by Daniel Melendez, a microbiologist and Florida-licensed mold assessor. PureSpec is assessment-only and never remediates what it inspects. PureSpec covers Duval County, including Jacksonville, Jacksonville Beach, Atlantic Beach, Neptune Beach, Mayport.

“I think there’s mold somewhere in my house but I don’t know where.”
“I already know where the problem is, I just need it documented.”
“I can see something dark or fuzzy on a wall, can you tell me what it is?”
“How do I get the air in my house tested for mold?”
“Is it black mold? Can you test for Stachybotrys specifically?”
“I bought a DIY mold test kit at the hardware store. Can I trust the result?”
“My doctor mentioned ERMI or HERTSMI-2 testing, what is that?”
“I tested positive for mycotoxins in my body, where did they come from?”
“The air test was normal but I still feel sick at home.”
“We just moved in or renovated and something doesn’t feel right.”
“The remediation company says it’s clean. How do I know?”
“Could my air conditioner be making us sick?”
Duval County-area CIRS and chronic-illness patients often work with integrative practices in Mandarin, San Marco, and the Jacksonville Beach corridor, which routinely use these results as part of an environmental workup. The pattern shows up particularly in the older Riverside / Avondale, San Marco, and Springfield historic-district inventory where HVAC retrofits on pre-war envelopes commonly create condensate issues.
How an Duval County inspection actually works
Nine steps. Same scientific process, every Duval County property.
The depth of each step adapts to your situation. HVAC and borescope inspection happen when conditions warrant. Sampling is decided based on what your specific environment is asking, not a fixed checklist.
- 01
Consultation
We talk through what you’re seeing, the building, and the question you need answered. Free, no pressure, no upsell.
- 02
Visual inspection
Daniel personally walks every accessible space in the Duval County property. No subcontractors.
- 03
Moisture mapping
Pin and pinless moisture meters identify elevated wall, floor, and substrate moisture invisible to the eye. Pre-war pier-foundation crawl-space moisture is the recurring finding in historic Duval, St. Johns, and Alachua inventory; substructure mapping catches what surface inspection cannot.
- 04
Thermal imaging
Infrared imaging surfaces temperature differentials that often correlate with hidden moisture or insulation gaps. Useful on Riverside / Avondale, San Marco, and Springfield historic-district envelopes where post-renovation flashing failures concentrate.
- 05
HVAC evaluation
Coil, plenum, return, and ductwork assessment. A frequent hidden source of indoor mold in Florida buildings. HVAC retrofits on historic-district homes frequently undersize the return path; we evaluate plenum and coil integrity at every inspection.
- 06
Targeted sampling
Air, surface, swab, ERMI, HERTSMI-2, mycotoxin, Pathways™, VOC, or formaldehyde, only the tests your situation warrants.
- 07
Lab analysis
Samples sent to AIHA-LAP-accredited third-party laboratories. Results returned within 24 to 72 hours of receipt.
- 08
Written report
Plain-English report with photos, lab data, moisture readings, observations, and clear next steps. Written so an insurer, a lender, a healthcare provider or an attorney can follow the reasoning behind each conclusion.
- 09
Remediation protocol when warranted
If the report identifies remediation-grade mold, Daniel writes the IICRC S520-aligned remediation protocol, scope, containment, methods, and clearance criteria, that the remediation contractor works to. PureSpec does not remediate, so the protocol stays independent of the work crew.

FAQ
Duval County questions, answered.
Do you serve NAS Jacksonville and NS Mayport military transferees?
Yes. The two bases generate continuous out-of-state-transferee pre-purchase demand year-round. PureSpec scopes inspections that layer cleanly onto the standard home-inspection report for military families relocating in or out of Duval.
Do you cover the pre-war Riverside-Avondale and San Marco historic districts?
Yes. The 1910s-1930s pre-war historic inventory gets the full historic-stack inspection: pier-foundation crawl-space moisture, balloon-framed wall cavity verification, original casement leak assessment, and stack-effect humidity in unconditioned attics.
Do you still find Hurricane Matthew, Irma, and Idalia legacy issues?
Yes. The 2016 Matthew surge into the Jacksonville Beach / Atlantic Beach barrier strip, the 2017 Irma record-flood downtown river inundation, and the 2023 Idalia wind-driven rain across the western county all produced partial-remediation work that PureSpec still documents in 2026 inspections.
How quickly can you schedule a Duval / Jacksonville inspection?
Most non-emergency Duval inspections book within 7-10 business days from Orlando. Travel is 2.5-3 hours each way, so appointments are typically grouped in 2-day visits. Active military-relocation cases and hurricane-claim work are prioritized.
