Mold Inspection &
Moisture Mapping

Visual + Infrared Screening + Moisture Meter Verification

Sampling is only part of the story. Most mold problems are moisture problems first. A strong inspection focuses on identifying where water is getting in, where it’s staying trapped, and what materials are impacted.

Inspection & Moisture Mapping

Our inspection combines visual assessment, infrared thermal screening, and moisture meter verification to build a clear picture of what's happening in your home. The goal is to identify the moisture pathway—not just confirm mold exists.

IICRC publishes ANSI-accredited standards that emphasize best practices for restoration and mold-related work. NIOSH also provides the Dampness and Mold Assessment Tool (DMAT), grounded in visual/odor evidence of dampness and mold indicators.

What We Identify

What This Inspection Is Designed to Do

Identify Moisture Intrusion

Active or historical moisture pathways—leaks, seepage, condensation, drainage failures—that create conditions for mold growth.

Narrow Concealed Issues

Determine where hidden problems may exist behind finishes, in cavities, or within building assemblies using non-invasive screening tools.

Support a Remediation Plan

Provide the information needed for a remediation plan that addresses the real driver—not just the visible symptoms.

Infrared Screening

Infrared: A Screening Tool, Not a Verdict

Thermal Imaging for Moisture Anomaly Detection

Infrared thermal imaging showing moisture anomalies during mold inspection

Infrared helps us see temperature patterns that can suggest moisture, missing insulation, or air movement. But thermal patterns must be verified with a moisture meter before conclusions are made.

What Infrared Can Help Identify

  • Temperature anomalies suggesting moisture behind finishes
  • Missing or displaced insulation affecting wall performance
  • Air infiltration patterns around windows, doors, or penetrations
  • HVAC-related temperature differences that may contribute to condensation

What Infrared Cannot Do

  • ×Detect mold directly—it shows temperature, not biology
  • ×Confirm moisture without meter verification—cold spots have multiple causes
  • ×See through all materials equally—surface emissivity and conditions affect readings
  • ×Provide a "pass/fail" result—interpretation requires context
Moisture Verification

Moisture Meter Verification

Why It Matters

Moisture meter verification during mold inspection

Moisture meters help confirm whether materials are elevated relative to surrounding areas and whether the condition is consistent with a current moisture pathway. This verification step is what turns a thermal anomaly into an actionable finding.

Comparative Readings

We compare readings across adjacent areas and materials to identify patterns—not just isolated numbers.

Material-Specific Context

Different materials have different baseline moisture levels. Drywall, wood framing, and concrete all read differently—interpretation accounts for this.

Pathway Identification

By mapping moisture patterns across a wall or room, we can trace the likely pathway—where water entered, where it traveled, and what it affected.

FAQ

Frequently Asked Questions

Can infrared detect mold directly?

No. Infrared detects temperature differences that can suggest moisture, missing insulation, or air movement—but it cannot see mold. It’s a screening tool that helps us identify areas warranting further investigation with a moisture meter or sampling.

Do I need sampling if the inspection finds visible mold?

Not always. If visible growth is clearly present and the moisture source is identified, the priority is moisture correction and remediation. Sampling adds value when the extent is uncertain, when you need documentation, or when the situation involves a dispute or insurance claim.

What’s the difference between a moisture meter reading and a moisture problem?

A single elevated reading may or may not indicate a problem—context matters. We compare readings across surrounding areas and materials, look at patterns, and consider building history. An isolated high reading near a shower valve tells a different story than a consistent pattern across an entire wall.

How long does a typical inspection take?

It depends on the size of the home and the complexity of the concern. A focused assessment of one or two areas may be straightforward, while a whole-home evaluation for a real estate transaction or multi-area odor complaint requires more time. We’ll discuss scope during your initial consultation.

When Testing Is Needed

When Sampling Follows Inspection

Inspection identifies the moisture pathway. When additional data is needed to define scope, document conditions, or evaluate concealed areas, targeted sampling builds on the inspection findings.
