FAQ

No — visible mold is not always present. Hidden mold growth behind walls, under floors or in HVAC systems can still trigger symptoms. So even if you don’t see mold, you can still suffer exposure effects.

We begin with an Initial Consultation to review the building’s history of leaks/flooding, occupant health symptoms, and property construction/ventilation. Then we conduct a Visual & Moisture Inspection using thermal imaging, moisture meters, inspection scopes and optionally mold-sniffing dogs, to locate hidden moisture or mold sources.

After that, we Comprehensive Mold Testing beyond simple air samples — including dust sampling (“The Dust Test”), ERMI (Environmental Relative Moldiness Index) testing for mold DNA, and surface swabs, with accredited lab analysis.

Lastly, we provide a full report of mold species, concentrations, thermal/moisture data, and provide a custom Action Plan for remediation, filtration, dehumidification and referrals.

Because air tests capture what’s floating in the air at one moment in time only, which may miss spores or fragments settled in dust or behind surfaces. At TNK Inspections, we don’t rely solely on air tests.

Mold thrives where moisture accumulates. Some typical hidden locations include inside wall cavities behind drywall, beneath carpets or carpet padding, in crawl spaces or attics, inside HVAC ducts, under or behind baseboards, around plumbing fixtures, and behind window frames or furniture against cool exterior walls.

Some red flags include: a musty or earthy odor with no obvious source; persistent condensation or dampness on windows or walls; dark stains or warping of materials; peeling or bubbling paint; unexplained health symptoms that improve when you leave the building; past history of water leaks/flooding.

No. Mold can be hidden in walls, ceilings, under flooring, or in ductwork. Some mold is hidden growing behind wall coverings or ceiling tiles… even dry, dead mold can cause health problems. So visibility is not a reliable indicator of absence.

TNK uses several methods, including:

• The Dust Test: analyzing settled dust for mold spores and fragments.
• ERMI (Environmental Relative Moldiness Index): a DNA-based test developed by the EPA to provide a “mold score”.
• Surface/Swab Testing: from targeted areas (HVAC vents, window sills, under sinks).
• Moisture measurements, thermal imaging, wall probes to map hidden moisture and likely mold growth locations.

TNK sends samples to an accredited national lab; then the report includes: detected mold species (toxic, allergenic, common), concentration levels compared to normal indoor environments; visual summary of readings and affected areas; moisture data and thermal images linking mold to sources.

A personalized “Action Plan” for remediation recommendations (affected areas), cleaning/filtration guidance (HEPA vacuums, air purifiers), moisture control strategies (dehumidification, ventilation upgrades), and referrals to trusted remediation contractors is may also be provided.

Yes. If you have unexplained symptoms (fatigue, sinus issues, headaches) that improve outside the building, and there’s a history of leaks or high humidity, it’s wise to schedule an inspection. If you’ve been told your home or office is ‘mold-free’ but you still feel unwell indoors, our proven process can reveal what standard air tests often miss.

Moisture is the key driver for mold. According to the EPA and health guidance: if moisture/condensation is present, spores landing on wet surfaces will grow.

Therefore, fixing leaks, ensuring proper ventilation, dehumidifying damp spaces, drying wet materials promptly, and controlling humidity (ideally < 50%) are essential for prevention.

No — a single air sample may miss hidden contamination or settled spores. Many tests don’t detect what’s behind walls or under floors. A comprehensive inspection including moisture mapping, dust testing, surface swabs, and evaluation of building history is much more reliable.

In short: absence of visible mold or a “normal” air test does not guarantee absence of mold problems.
