Moisture mapping is a comprehensive and effective method for detecting hidden moisture sources, especially under houses. It involves utilizing specialized equipment to create detailed maps that pinpoint areas where moisture may be penetrating the structure.

### Moisture Detection Methods

Various methods are employed in moisture mapping, each with its own advantages and applications:

– **Infrared Thermography:** Infrared cameras generate heat maps, highlighting areas of temperature variation that may indicate moisture accumulation.
– **Moisture Meters:** Invasive devices that measure the moisture content within building materials.
– **Hygrometers:** Sensors that measure the air’s humidity levels, detecting potential moisture issues.
– **Ground Penetrating Radar (GPR):** Non-invasive technology that uses electromagnetic waves to detect moisture pockets or leaks underground.

### How to Check for Moisture Under My House

Identifying moisture sources beneath your house is crucial for maintaining its structural integrity. Here’s a step-by-step guide to help you:

1. **Examine the Basement or Crawl Space:** Look for signs of mold, mildew, condensation, or water stains.
2. **Inspect the Foundation Walls:** Check for cracks, holes, or efflorescence (a white, powdery substance indicating moisture seepage).
3. **Observe the Soil:** If the soil around your house is damp or saturated, it could be a sign of water accumulation.
4. **Contact a Professional:** For thorough and accurate moisture detection, it is recommended to hire a certified moisture mapping expert.
