Mold Surface & Swab Testing

Not every dark patch is what it looks like, and knowing the species and whether it’s active changes the response. Surface and swab sampling identify what’s growing on a specific spot.

Mold Surface & Swab Testing — the problem we remediate

The problem

Identify the Specific Spot

Tape lifts and swabs capture material from a visible patch for lab identification — species and viability. It answers the question a look alone can’t: what is this, and is it active.

The approach

The Right Test for the Question

Surface testing confirms what a spot is; air testing finds hidden sources. Often the two work together — we’ll recommend what actually answers your question rather than over-testing.

  1. Hidden growth. Mold hides in wall cavities, behind tile, and inside ductwork.
  2. We sample the air. A calibrated pump captures the spores you can smell but can’t see.
  3. Data, not a guess. Lab results locate the source — and confirm when it’s clear.
You can smell it but not find it — because the growth is usually behind a surface. Testing locates the source and confirms, later, that it’s actually gone.

How it works

A Documented Process, First Look to Verified Result.

  1. 01 Inspection & Moisture Mapping We walk the property and trace where moisture is feeding growth.
  2. 02 Air & Surface Sampling Calibrated air samples and surface swabs from suspect areas.
  3. 03 Accredited Lab Analysis Samples sent to an independent lab for species and counts.
  4. 04 Written Report Findings, indoor-vs-outdoor comparison, and a clear recommendation.
  5. 05 Next Steps Remediation guidance if needed — or documented peace of mind.

Common questions

Before You Call, the Honest Answers.

Can’t you tell what mold is by looking?

You can suspect, but only a lab can identify the species and whether it’s active — and that can change whether and how it’s remediated. Surface testing settles it.

What’s the difference from air testing?

Surface testing identifies a specific visible patch; air testing measures spores in the air to find hidden growth. They answer different questions and sometimes pair up.

Do I need testing before remediation?

Not always — an obvious mold problem with a known cause can go straight to remediation. Testing is most useful when it’s unclear what you have or whether there’s a hidden source.
