My story

From a microscope in the lab to your home in Florida.

Daniel Melendez is an Indoor Environmental Professional (IEP), Florida State Licensed Mold Inspector (MRSA #4575), and microbiologist. His story, and why PureSpec exists.

Where it started

I studied microbiology, four years of looking at organisms under a microscope, learning how they grow, what they need, and why they show up where they do. When I graduated, I wanted to put that science to work, so I moved to Florida with a degree, a few suitcases, and no contacts.

Behind the microscope

My first job out of college was as a mold analyst inside an environmental laboratory. I spent thousands of hours under a microscope identifying spores at species level, reading the exact samples that other Florida inspection companies were sending in.

Eventually I was the one training new analysts: how to read slides correctly, how to distinguish actual growth from debris, how to identify species, and how to write findings that hold up in a report. The lab put me in that role because I had both the science background and the eye, and because the analysts being trained had to be ready to interpret samples for inspectors all over the state.

That's a rare path in this industry. Most mold inspectors learn from a weekend course. I learned by doing the lab work and then teaching it. By the time I went into the field, I already knew what every species meant, where it lived, and what the numbers were really saying. When you book PureSpec, the person walking your property is the same person who taught other analysts what those numbers should look like.

Why I started PureSpec

After enough time in the lab, I wanted to be the one in the field, bridging what the science actually shows with what homeowners actually need to know. I founded PureSpec to bring the microbiologist directly to the property.

PureSpec is assessment-only. I focus on one job: giving you a clear, science-backed picture of what's happening in your building, what it means, and what to do next. Today I run PureSpec out of Orlando and serve all 15 Florida counties, every inspection is performed personally, no subcontractors, no rotating crews. The person you book is the person who shows up.

The credentials

  • Indoor Environmental Professional (IEP): the modern professional designation defined in the IICRC S520 standard for the third-party expert who assesses, samples, and scopes microbial conditions. IEP is the term replacing "mold inspector" as the industry moves toward standardized professional language.
  • Bachelor of Science, Microbiology: the academic foundation in microorganism identification, growth conditions, and analytical microbiology.
  • Former environmental laboratory analyst, and trainer of analysts: thousands of mold samples analyzed under the microscope, then promoted to training new analysts on slide reading, species identification, and report-quality findings. A path most Florida mold inspectors never take.
  • ACAC Certified Microbial Investigator (CMI): American Council for Accredited Certification. One of the most rigorous microbial-investigation certifications in the United States.
  • Florida State Licensed Mold Inspector & Assessor: MRSA #4575, issued by the Florida Department of Business and Professional Regulation. The state license required to legally perform mold inspection and assessment in Florida.
  • Respirare Labs listed provider: featured on the public Respirare Labs mycotoxin testing provider directory for AMEA and MESA panel ordering in Florida. Independent, cross-verifiable third-party listing.

How I work

Every inspection is personal. I show up, I walk the building, and I sample what needs sampling. I build the report on-site, in real time: photos, moisture readings, observations, and findings captured the moment I see them, not reconstructed from memory at a desk later. Nothing gets paraphrased. Nothing gets forgotten.

The phone goes directly to me, not a call center. Most Orlando-area clients are scheduled within 48 hours, with statewide travel available across all 15 Florida counties. I built this company with three things: the science I trained for, the work ethic I was raised with, and the kind of customer service most people stopped expecting from contractors.

If you call PureSpec, you're not getting a brand. You're getting Daniel.

How an inspection actually works

Nine steps. Same scientific process, every 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.

  1. 01

    Consultation

    We talk through what you’re seeing, the building, and the question you need answered. Free, no pressure, no upsell.

  2. 02

    Visual inspection

    Daniel personally walks every accessible space. No subcontractors.

  3. 03

    Moisture mapping

    Pin and pinless moisture meters identify elevated wall, floor, and substrate moisture invisible to the eye.

  4. 04

    Thermal imaging

    Infrared imaging surfaces temperature differentials that often correlate with hidden moisture or insulation gaps.

  5. 05

    HVAC evaluation

    Coil, plenum, return, and ductwork assessment. The #1 hidden vector for indoor mold in Florida buildings.

  6. 06

    Targeted sampling

    Air, surface, swab, ERMI, HERTSMI-2, mycotoxin, Pathways™, VOC, or formaldehyde, only the tests your situation warrants.

  7. 07

    Lab analysis

    Samples sent to AIHA-LAP-accredited third-party laboratories. Results returned within 24 to 72 hours of receipt.

  8. 08

    Written report

    Plain-English report with photos, lab data, moisture readings, observations, and clear next steps. Built to hold up with insurers, lenders, healthcare providers, and counsel.

  9. 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. Florida law prohibits the same firm from inspecting and remediating, so the protocol stays independent of the work crew.
