What Is Mold Testing?

Mold testing involves collecting samples from your property to determine:

  • What types of mold spores are present

  • Whether mold is growing in hidden areas

  • If airborne levels are elevated or abnormal

  • Whether discoloration is actually mold or something else

Unlike a mold inspection, which focuses on identifying conditions visually and with tools, mold testing provides lab-confirmed evidence of mold exposure.

What Types of Mold Testing Do We Offer?

We provide three types of professional mold sampling:

Air Sampling

Air testing collects airborne mold spores in different rooms of your home or building. Using a professional-grade sampling pump:

  • We draw air into a cassette for 5–10 minutes per location

  • A separate outdoor control sample is collected to compare indoor vs. outside spore counts

  • Samples are analyzed for total spore load and mold species

🧬 Best for: Musty odors, general air quality concerns, post-remediation clearance, and health-related investigations

Surface Swab Testing

Surface sampling confirms whether visible staining, spotting, or discoloration is actually mold.

  • A sterile swab or tape lift is collected from drywall, tile, wood, insulation, vents, or furnishings

  • The lab identifies the mold genus (e.g. Cladosporium, Aspergillus, Stachybotrys)

🧬 Best for: Confirming visible mold, identifying species, or verifying if cleaning/removal was effective

Wall Cavity Air Sampling (In-Wall Mold Testing)

When mold is suspected behind walls or ceilings, we perform in-wall air sampling (aka cavity testing):

  • A small, penny-sized hole is drilled into the wall or ceiling

  • A sterile air tube is inserted to draw a sample from inside the cavity

  • The sample is analyzed for mold spores by volume and type

🧬 Best for: Hidden mold detection, unexplained odors, water-damaged walls, or pre-renovation clearance

Cavity testing is minimally invasive, and we can either seal the opening or leave it accessible for a contractor. It provides a powerful look inside without opening large areas.

When Should You Get Mold Testing?

You may benefit from mold testing if:

  • You smell something musty but don’t see visible mold

  • You’re sensitive to mold and need air quality confirmation

  • You’re in a real estate transaction that requires documentation

  • You’re doing remediation or renovation and want to confirm safety

  • You’re a tenant or landlord involved in a mold dispute

  • You’re working with a doctor or attorney and need lab evidence

  • You’re prepping a home for sale and want to rule out airborne issues

Unlike inspections, testing focuses entirely on the biological content of your space — giving you real lab data to make confident decisions.

How Mold Samples Are Collected

Here’s what happens during a standard mold testing appointment:

  1. Discussion of your concerns and property history

  2. Targeted air samples collected in concern areas and outdoors

  3. Surface swabs or tape lifts from visible staining or suspect growth

  4. Cavity air sample (if needed), using a specialized tube through a small access hole

  5. Labeling and secure packaging of all samples

  6. Samples are shipped to a licensed lab the same day

📄 You’ll receive a full lab report + our interpretation within 2–3 business days.

What Will the Lab Report Show?

Every certified mold test includes a detailed lab report showing:

  • Mold types (e.g. Penicillium, Aspergillus, Stachybotrys, Chaetomium)

  • Spore counts per cubic meter of air (air samples)

  • Confirmation of mold presence on swabs (surface samples)

  • Our interpretation of whether levels are elevated or normal

  • Next steps or clearance confirmation (if applicable)

These reports are often used for:

  • Insurance claims

  • Real estate disclosures

  • Legal cases

  • Medical documentation

  • Remediation verification
