Air Quality Testing

Is mold from the crawlspace getting into your living space?

An air quality test answers that question with data, not guesswork. We collect air samples from your living areas and compare them to a same day outdoor sample, so you can see whether mold spores inside the home are elevated above what’s naturally in the air outside.

Indoor Sample
Outdoor Control

Indoor results are only meaningful when measured against an outdoor baseline.

What the Test Actually Measures

An air quality test doesn’t just tell you mold is “present,” it gives you specific, comparable data.

Spore Types

The lab identifies the specific types of mold spores present in each sample, not just a general yes or no on whether mold is in the air.

Spore Counts

Each spore type is counted, giving you an actual number for indoor air and for outdoor air, instead of a vague description.

Outdoor Control Sample

An outdoor sample is collected the same day to establish what’s naturally in the local air, since mold spores exist outdoors everywhere.

Indoor vs. Outdoor Comparison

Each room is rated None, Slight, or Major elevation based on how its spore types and counts compare to the outdoor sample, so you know exactly where to focus.

How the Test Works

1

Outdoor Control Sample

Collected first, outside the home and away from obvious mold sources, to set the baseline for what’s normal that day.

2

Indoor Air Samples

Collected in the living areas, the rooms people actually spend time in, not just the crawlspace itself.

3

Lab Analysis

Samples go to Sporecyte’s accredited lab, where AI analyzes 100% of each sample and a PAACB certified spore analyst confirms the results.

Comparison Report

You receive a report rating each room None, Slight, or Major elevation compared to the outdoor control, along with photos of what was found, so it’s clear whether the air inside is elevated.

Why This Matters for Crawlspace Concerns

A damp or moldy crawlspace doesn’t always stay contained to the crawlspace. Air moves between a crawlspace and the living space above it through gaps around plumbing, HVAC returns and supply lines, and the natural stack effect that pulls air upward through a house.

If that’s happening in your home, an air quality test is how you find out. Instead of guessing based on smell or what’s visible in the crawlspace, the test measures what’s actually in the air people are breathing upstairs and compares it to a same day outdoor sample.

What We’re Looking For

  • Indoor spore counts that are elevated relative to the outdoor control
  • Spore types often associated with water intrusion, such as Stachybotrys or Chaetomium, appearing indoors but not in the outdoor sample
  • Overall patterns that point to an indoor source rather than normal background air

What This Looks Like in Practice

In one example report, a basement sample measured roughly seven times the outdoor control’s spore count, including mold types tied to water damage that weren’t present outdoors at all. A bedroom sample in the same home came back essentially identical to the outdoor air, no elevation at all.

Powered by Sporecyte

AI-analyzed. Analyst-confirmed.

We run our air quality samples through Sporecyte, an AI powered mold and air particulate lab. Their technology scans 100% of each sample in minutes, compared to the roughly 30% a traditional manual count typically covers, and every result is then reviewed and confirmed by a PAACB certified spore analyst before your report is finalized.

The lab is PJLA ISO/IEC 17025:2017 accredited and identifies more than 90 mold spore types, along with common air particulates like pollen, insect parts, and skin cells.

Common Questions

What is an air quality test? +

It’s a lab based test that collects air samples from your home and identifies and counts the mold spore types present. An outdoor sample is collected the same day so the indoor results have a baseline to be compared against.

How does this tell me if mold is coming from the crawlspace? +

If the air in your living areas shows elevated spore counts, or spore types that don’t show up in the outdoor sample, that points to an indoor source rather than normal background mold that’s present in outside air everywhere. The comparison is what makes the result meaningful.

What’s the difference between this and a mold inspection? +

Air quality testing focuses on what’s actually in the air using lab analyzed samples and counts. A visual mold inspection focuses on visible growth, moisture readings, and likely sources. The two are often used together for a complete picture.

How long does it take to get results? +

Samples are analyzed through Sporecyte, an AI powered lab that offers same day report turnaround on samples they receive by their weekday cutoff. We’ll let you know the expected timeline when you schedule.

Can I add this to a home inspection? +

Yes. Air quality testing can be added to a home inspection or scheduled as a standalone service. Let us know when you schedule and we’ll work it into the visit.

Can you test surfaces too, like crawlspace framing or insulation? +

Yes. Alongside air samples, we can collect a surface swab or tape lift from a specific area of concern to check for active mold growth directly on that material. It’s often paired with air sampling for a fuller picture, especially when a crawlspace or basement is the suspected source.

Does a high spore count always mean there’s a problem? +

Not on its own. Spore counts are interpreted by comparing indoor results to the outdoor control, not as an isolated number. Your report walks through what the comparison shows so you can make an informed decision about next steps.
