What is mold inspection in St. Johns County?
A mold inspection in St. Johns 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 surface-temperature patterns worth confirming with a moisture meter, an evaluation of the air conditioning system, 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 performs environmental assessment and testing only. It never performs remediation. PureSpec covers St. Johns County, including St. Augustine, Ponte Vedra Beach, Nocatee, World Golf Village. Service in this area is available by appointment with a written custom quote. Contact PureSpec for current availability.

“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?”

How an St. Johns County inspection actually works
Twelve steps. Same scientific process, every St. Johns County property.
The depth of each step adapts to your situation. Tracer smoke testing 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
Humidity and dew point
Temperature, relative humidity and dew point are recorded room by room, with an outdoor reference, because a surface colder than the dew point collects water without any leak.
- 03
Indoor air quality screening
Real-time particle counts across size channels, with on-site carbon dioxide, VOC and formaldehyde screening, room by room. Screening, not laboratory analysis.
- 04
Comprehensive HVAC evaluation
Each air handler is opened and checked: blower compartment, coil, drain pan, supply and return plenums, filter, and the attic duct runs it feeds. 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.
- 05
Tracer smoke testing when needed
Smoke makes local air movement visible at the HVAC system and around penetrations and openings; temperature, humidity and surface-temperature readings help evaluate whether condensation is possible.
- 06
Mold visual inspection
Daniel personally walks every accessible space in the St. Johns County property. No subcontractors.
- 07
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.
- 08
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.
- 09
Targeted sampling
Air, surface, swab, ERMI, HERTSMI-2, mycotoxin, Pathways™, VOC, or formaldehyde, only the tests your situation warrants.
- 10
Lab analysis
Samples sent to AIHA-LAP-accredited third-party laboratories. Results returned within 24 to 72 hours of receipt.
- 11
Written report
Plain-English report with photos, lab data, moisture readings, observations, and clear next steps. Organized so the client and relevant third parties can follow the observations, data, methods and basis for the assessment conclusions.
- 12
Remediation protocol when warranted
If assessment findings support professional remediation, Daniel can write, as an optional add-on quoted separately, 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
St. Johns County questions, answered.
Do you inspect historic wood-frame buildings in St. Augustine?
Yes. St. Augustine is the oldest continuously-inhabited European-founded city in the United States, and that produces a substructure inspection profile unlike anywhere else in Florida. Pre-1900 wood-frame, tabby, and coquina-stone buildings, pier and crawl-space foundations, and centuries of envelope-renovation layers all interact. Daniel performs both standard inspections and the more technical historic substructure assessments these buildings often require.
Do you cover Ponte Vedra Beach and Nocatee?
Yes. The Ponte Vedra Beach / Nocatee / Sawgrass corridor is a core service area. Pre-purchase inspections of higher-end inventory and post-construction inspections of new-build Nocatee homes dominate the workload here.
Are St. Johns County homes still being inspected after Hurricane Matthew and Irma?
Some, yes. Both storms (Matthew 2016 and Irma 2017) caused significant flooding in low-lying St. Augustine and along the Intracoastal Waterway. Most acute work has long since concluded, but pre-purchase buyers and CIRS-aware patients still occasionally encounter incompletely-remediated properties from that era.
How much does mold inspection cost in St. Johns County?
Pricing scales with property size and scope. Limited-scope inspections in St. Johns County start in the mid-hundreds; entire-property inspections including air sampling start higher. Historic St. Augustine substructure work and Ponte Vedra Beach high-end inventory are quoted based on access complexity and sampling depth. Call (321) 324-7756.
Do you have a St. Johns County office?
No. PureSpec is headquartered in Winter Garden and travels to St. Johns County by appointment. Contact PureSpec for current availability. The trade-off for not pretending to have a local office is that one credentialed person, Daniel Melendez, personally performs every inspection statewide.
