Moisture Detection Tools Used by Professionals

When it comes to water damage, what you see is only part of the story. Moisture can hide inside walls, beneath floors, and behind ceilings — and without proper tools, it goes undetected until mold or structural damage appears.

At Purisync Heating and Air, we use industry-grade moisture detection equipment to locate and measure moisture fast — without tearing your home apart. Here’s a closer look at the most common tools we use during inspections across Kirkwood and nearby Missouri areas.

1. Moisture Meters

These handheld devices measure the moisture content of materials like drywall, wood, and concrete. There are two main types:

• Pin-type: Uses metal probes to measure resistance between two points. Ideal for getting deep readings in walls or wood framing.
• Pinless (non-invasive): Uses electromagnetic sensors to scan surfaces without puncturing them — perfect for finished walls or flooring.

2. Infrared (IR) Thermal Imaging Cameras

Thermal cameras detect temperature differences across surfaces, which can reveal cold spots caused by hidden moisture. While they don’t directly detect water, they help pinpoint areas for deeper inspection with a moisture meter.

3. Hygrometers (Humidity Meters)

Hygrometers measure the relative humidity in a room or structure. High humidity levels (over 60%) increase the risk of mold growth and moisture buildup — even when there’s no active leak.

4. Borescopes (Inspection Cameras)

When needed, we use a small camera attached to a flexible cable to inspect inside walls, HVAC ducts, and crawlspaces for visible moisture, mold, or damage without major demolition.

5. Calcium Carbide Test (For Concrete Moisture)

In commercial or structural inspections, this test helps measure moisture in concrete slabs — commonly used before flooring installations or large renovations.

Why Professional Tools Matter

Consumer-grade meters or visual checks often miss critical moisture. Our tools allow us to:

• Find leaks before mold grows
• Verify that areas are fully dry before repairs
• Prevent structural decay and warped materials
• Document accurate moisture levels for insurance claims

Our Moisture Inspection Process

1. Initial walkthrough and symptom check
2. Scanning high-risk areas using non-invasive tools
3. Pinpointing saturated materials for removal or drying
4. Reporting and recommending next steps (drying, mold testing, etc.)
