FAQ: How Do You Measure Moisture Levels in a Crawl Space After Water Damage?

If you’ve had standing water or a leak under your home, you might be wondering: how do we actually know when the crawl space is dry? Here’s how we do it.

Our Tools: Moisture Meters and Thermal Imaging

At Total Home Water Restoration, we use two key tools to track crawl space moisture:

• Moisture Meters: These measure the actual water content in materials like floor joists, subfloor, insulation, and sometimes even the soil. We use both pin and pinless meters, depending on the surface.

• Thermal Imaging Cameras: These cameras spot temperature differences caused by moisture. Wet materials usually show up cooler than dry ones. This lets us find hidden damp spots that aren’t visible to the eye.

What We Measure:

• Wood framing (joists, sill plate, subfloor)

• Insulation (especially fiberglass or spray foam)

• Concrete walls or footers

• Soil or vapor barrier condition

We scan each area and document readings before, during, and after drying. If it’s not dry, we keep going until it is. You’ll always get a full report showing the results.

Why It Matters

Here’s why tracking moisture is so important:

• Mold prevention: Mold grows fast when wood or insulation stays damp.

• Structural safety: Wet wood can warp, rot, or attract termites.

• Insurance claims: Proper documentation helps support your claim and proves the work was done right.

Real Example from Grove City

We helped a homeowner in Grove City who found standing water in their crawl space after a heavy storm. Using our thermal camera, we spotted soaked insulation that didn’t look wet at first glance. Moisture meters confirmed it. We pulled it out, set up drying equipment, and monitored it for several days—checking wood moisture content until it dropped to a safe level.
