**Moisture Mapping**

Moisture mapping is a non-invasive method used to detect and map moisture levels in buildings. By analyzing moisture patterns, professionals can identify potential sources of water damage and take appropriate action to address them.

**Detection Methods**

* **Thermal Imaging:** Thermal cameras detect temperature differences, which can indicate the presence of moisture. Damp areas tend to be cooler than dry areas, making them visible on thermal images.
* **Moisture Meters:** Moisture meters measure the electrical resistance of materials. Higher resistance typically indicates lower moisture levels.
* **Infrared Cameras:** Infrared cameras detect moisture by capturing heat radiation emitted by wet surfaces.
* **Capacitance Sensors:** Capacitance sensors measure the water content in building materials based on electrical properties.

**How to Check for Moisture Under Your House?**

To check for moisture under your house, consider the following steps:

* **Inspection:** Inspect the foundation, crawl space, and basement for signs of water damage, such as stains, mold, or peeling paint.
* **Crawl Space:** If accessible, enter the crawl space and look for dampness, mold, or rotting wood. Note any musty odors or condensation.
* **Moisture Meter:** Use a moisture meter to measure moisture levels in walls, floors, and structural elements.
* **Thermal Imaging:** Hire a professional to conduct thermal imaging to detect hidden moisture patterns.
* **Contact a Professional:** If you suspect significant moisture issues, contact a licensed moisture mapping expert for a thorough inspection and mitigation plan.
