Mold Inspection, Mold Testing & Specialty Testing in Jacksonville, Florida.
Founder-performed by Daniel Melendez, a microbiologist and former environmental lab analyst. Lab-supported, independent of remediation, with Jacksonville inspections scheduled by appointment from Orlando, typically within the same week.
What is mold inspection in Jacksonville?
A mold inspection in Jacksonville 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 Jacksonville, including St. Johns River flood zones, Riverside / Springfield historic homes.

Which service you need

Find the question closest to yours. Every service is performed personally by Daniel Melendez, a microbiologist and former environmental lab analyst, and every sample ships to an AIHA-LAP-accredited third-party laboratory under chain-of-custody.
“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?”
Jacksonville-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 Jacksonville inspection actually works
Nine steps. Same scientific process, every Jacksonville 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 Jacksonville 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
Jacksonville questions, answered.
Do you inspect homes in St. Johns River flood zones?
Yes. The St. Johns River corridor and its tributaries (Ortega River, Trout River, Arlington River) put significant Jacksonville inventory in FEMA AE flood zones. We routinely inspect San Marco, Ortega, Avondale, and Riverside properties for substructure moisture, sub-floor microbial growth, and post-flood envelope damage that wasn't fully addressed at the time of the event.
Do you do military landlord-tenant inspections near NAS Jacksonville?
Yes. The Naval Air Station Jacksonville rental market generates steady landlord-tenant inspection demand. PureSpec documents the environmental conditions found and reports them, so the tenant, the landlord, a code office, or an attorney has an independent factual record, and we can scope work for active-duty tenants on a tight PCS timeline. See /services/tenant-friendly-mold-inspection/.
Do you inspect Riverside, Avondale, and Springfield historic homes?
Yes. Riverside, Avondale, and Springfield carry one of the deepest pre-war wood-frame inventories in Florida. Recurring findings include pier-foundation substructure moisture, original window-flashing failure, and crawl-space biofilm in homes that have never had a vapor barrier installed.
Are you available for ERMI or Pathways Testing in Jacksonville?
Yes. Daniel is a Certified Pathways Technician and collects ERMI and HERTSMI-2 dust DNA samples to EPA-validated protocol for Jacksonville-area patients undergoing CIRS, MCAS, or chronic-illness workups, including referrals from integrative-medicine clinics in the Riverside and Ponte Vedra corridors.
Do you still inspect properties hit by Idalia (2023) or Ian (2022) in Duval County?
Yes. Idalia flooded portions of Jacksonville Beach, Atlantic Beach, and the Intracoastal corridor in August 2023; Ian brushed Duval County in 2022 with wind-driven rain. Concealed moisture from both events continues to surface in 2026, particularly in re-finished drywall covering wet sheathing on the barrier-island and Intracoastal-side inventory.
