HERTSMI-2 Dust Testing in Charleston

Get laboratory findings you can understand—not a report you're left to decode.

HERTSMI-2 uses DNA-based analysis of collected dust to assess five selected molds. I offer this focused environmental test on its own or with indoor air quality testing. Every lab report comes with a post-test summary explaining the results.

If you are sensitized to indoor conditions, receiving cancer treatment, or living with an autoimmune disease or another underlying condition, you may have specific questions about your home. Bring any environmental testing instructions from your healthcare professional so we can discuss the requested scope before you book.

Dust testing versus air sampling

TestWhat it examines
HERTSMI-2Collected dust analyzed for five selected molds.
Mold air samplingAir collected at selected locations during the sampling period.

These methods provide different information; neither measures every mold or indoor pollutant. Environmental testing does not diagnose illness, establish the cause of symptoms, or certify a home as medically safe. Your healthcare professional handles medical interpretation.

Inspector and independence

Your inspector should explain the findings—not sell the cleanup

I handle your inspection and discuss the results with you directly. You can ask what was sampled, what the lab found, and what the findings mean for your property.

Because I do not perform remediation or repairs, a cleanup contract is not part of my recommendation. My job is to help you make an informed decision about the concern that brought you here.

Customer reviews

What customers say

“Jeff was outstanding to work with. He was professional, knowledgeable, and incredibly thorough throughout the mold inspection process. I appreciated his honesty, attention to detail, and clear recommendations without any pressure or upselling. His prompt, detailed report and excellent communication made the entire experience smooth and stress-free, and I highly recommend him to anyone needing a trustworthy mold inspector.”
Alex Thropp
“These men were wonderful, I have a new born baby and they came in and tested for us. Jeff was very polite and walked me through the service. I would suggest all new mothers testing their homes for their child's safety.”
Ellen Watts
“Shop around for a few quotes for a new home buy. I prefer to find my own guys and not through the realtor. These guys had their prices on the page so it made it easy to compare. Responded quickly and were able to meet me in 24 hours. Probably will go back to these guys of buying in the Charleston area.”
Kyle Johnson
“I had my apartment tested for mold. They were swift in response time, great pricing cheaper than the others in town. The two guys that came to do the testing were dressed well, professional and on time.”
Michelle Corbin
“Jeff was super knowledgeable and very helpful! He was quick to get us on his calendar on short notice which is always appreciated.”

Inspection decisions

The right testing starts with the right questions

Which of these sounds like your situation? Your answer shapes the testing plan, so the samples taken are the ones that answer your question.

For a separate radon concern, review radon testing in Charleston.

  • A musty odor or previous leak

    Where was the water? Was the source repaired? Has the odor returned? An inspection considers accessible areas and moisture readings before deciding whether samples would add useful information.

  • A home purchase or rental concern

    Tell me what raised the concern and when you need answers. A specific question about a leak, room, or prior repair helps define a useful inspection scope.

  • An older home or renovation

    Questions about building materials call for a different approach than questions about airborne mold. Explore asbestos testing, or ask about lead testing before selecting a service.

  • A property with different moisture conditions

    A downtown Charleston renovation, an island condo with a past leak, and a Summerville home with recurring condensation should not automatically receive the same sampling plan. The building's history and the affected areas matter more than its ZIP code.

Process

From property concern to explained results

One person from first call to final report. You talk to the inspector who collected your samples, not a call center.

  1. First

    Tell me what's happening.

    Share the location, water history, and any deadline. We'll discuss the service and scope.

  2. Then

    Inspect and sample where appropriate.

    A mold inspection includes visual assessment and moisture measurements in relevant accessible areas. Agreed samples go to a laboratory for analysis.

  3. Finally

    Review the findings.

    Your lab report includes a post-test summary. I'll explain the environmental findings so you understand the next steps.

What you receive

What will my mold test report tell me?

When testing is part of your inspection, you'll receive the lab results and a written summary from me. I'll explain where samples were taken, what the lab found, and how those findings fit with what I observed at your property. If a result raises a question about a particular room or moisture issue, I'll explain what's worth checking next.

Example: why the totals aren't the whole story

At a downtown Charleston property, both indoor air samples had lower totals than the outdoor sample. But the upstairs bedroom closet sample contained an estimated 2,000 spores/m³ in the Aspergillus/Penicillium group, a group the outdoor sample did not detect. Someone scanning only the totals could miss the biggest difference in the report.

Questions before you schedule

Call 843-460-2835

Not always. EPA guidance says sampling is usually unnecessary when mold is visible. An inspection can help assess moisture conditions and whether testing would answer a specific question.

Start with the property concern. Mold inspection, dust analysis, and air sampling serve different purposes. Tell me what you need to understand, including any environmental testing your clinician has requested, before selecting a package.

I do not perform mold cleanup or repairs. An optional remediation protocol is available for an additional $300, separate from the included post-test summary. Ask about its scope before adding it.

Timing depends on the test and laboratory processing. Confirm turnaround when booking, particularly for HERTSMI-2 or a property transaction with a deadline.

You don't need to choose a test before calling

Tell me about the property, the concern, and your deadline. I'll help you understand the inspection and testing options so you can decide how to proceed.
